I'm starting to think a middleware is probably the easiest solution that checks the request.user class and if is AnonymousUser then replaces it with a subclassed AnonymousUser that has the extra properties. That sound reasonable?

I want to make my User objects all have the same base behaviour and to do so I need to add a couple of methods / properties to Anonymous User. I've already subclassed User to make richer user objects but I was wondering if anyone has done the same for Anonymous User? And if there are any preferred ways of doing it!

This is Brian, the question asker. I have completed what I needed to do by just trial and error and hex editing, hex edit...then convert the source...see what I changed..until I finally narrowed down what I was looking for. The constants (Admin IDs) were in the hex file as converted hex (obviously) but backwards. I still have no idea how or where I'd find the != I heard IDA Pro newest version supports python, but I havent learned how to get python to work on it.

I have 2 .pyo python files that I can convert to .py source files, but they don't compile perfectly as hinted by decompyle's verify. Therefore looking at the source code, I can tell that config.pyo simply had variables in in an array: ADMIN_USERIDS = [116901, 141, 349244, 39, 1159488] I would like to take the original .pyo and disassembly or whatever I need to do inorder to change one of these IDs. Or.... in model.pyo the source indicates a if (productsDeveloperId != self.getUserId()): All I would want to do is hex edit the != to be a == .....Simple with a windows exe program but I can't find a good python disassembler anywhere. Any suggestions are welcomed...I am new to reading bytecode and new to python as well.

Convert the .pyo files to .py and then edit the .py and then run python on the .py files. Python will regenerate the .pyo files Don't edit the pyo I don't know the python bytecode but I would doubt that the strings == or 1= would appear in the .pyo file Although a much better way is get the original .py files and use them. If they give the wrong program as implied by wanting to change != to == then you could ask the supplier to fix the bug.

You might need to set the editor code completion settings. They are under: Window->Preferences->PyDev->Editor->Code Completion You might also need to add the Django install or your Django project to your path. You can set this under: Window->Preferences->PyDev->Interpreter - Python Hope this helps.

I've just started using IronPython as extensibility point in my ASP.NET MVC aplication. I have one ipy engine (in static property) and for each request I create new scope and execute the script in that scope. Each scope should be independent on other scopes, no locking is needed. If I run into issues, I'll post it here. However, I don't expect any ;)

I would like to create an ASP.NET MVC web application which has extensible logic that does not require a re-build. I was thinking of creating a filter which had an instance of the IronPython engine. What I would like to know is: how much overhead is there in creating a new engine during each web request, and would it be a better idea to keep a static engine around? However, if I were to keep a single static engine around, what are the issues I might run into as far as locking and script scope? Is it possible to have multiple scopes in the same IropPython engine so I don't get variable collision and security issues between web requests?

How do you extend the Site model in django?

I just used my own subclass of Site and created a custom admin for it. Basically, when you subclass a model in django it creates FK pointing to parent model and allows to access parent model's fields transparently- the same way you'd access parent class attributes in pyhon. Built in admin won't suffer in any way, but you'll have to un-register Sites ModelAdmin and register your own ModelAdmin.

Python templates for huge HTML/XML

python,templates

You don't need a streaming templating engine - I do this all the time, and long before you run into anything vaguely heavy server-side, the browser will start to choke. Rendering a 10000 row table will peg the CPU for several seconds in pretty much any browser; scrolling it will be bothersomely choppy in chrome, and the browser mem usage will rise regardless of browser. What you can do (and I've previously implemented, even though in retrospect it turns out not to be necessary) is use client-side xslt. Printing the xslt processing instruction and the opening and closing tag using strings is easy and fairly safe; then you can stream each individual row as a standalone xml element using whatever xml writer technique you prefer. However - you really don't need this, and likely never will - if ever your html generator gets too slow, the browser will be an order of magnitude more problematic. So, unless you benchmarked this and have determined you really have a problem, don't waste your time. If you do have a problem, you can solve it without fundamentally changing the method - in memory generation can work just fine.

Recently I needed to generate a huge HTML page containing a report with several thousand row table. And, obviously, I did not want to build the whole HTML (or the underlying tree) in memory. As result, I built the page with the old good string interpolation, but I do not like the solution. Thus, I wonder whether there are Python templating engines that can yield resulting page content by parts. UPD 1: I am not interested in listing all available frameworks and templating engines. I am interested in templating solutions that I can use separately from any framework and which can yield content by portions instead of building the whole result in memory. I understand the usability enhancements from partial content loading with client scripting, but that is out of the scope of my current question. Say, I want to generate a huge HTML/XML and stream it into a local file.

It'd be more user-friendly (assuming they have javascript enabled) to build the table via javascript by using e.g. a jQuery plugin which allows automatical loading of contents as soon as you scroll down. Then only few rows are loaded initially and when the user scrolls down more rows are loaded on demand. If that's not a solution, you could use three templates: one for everything before the rows, one for everything after the rows and a third one for the rows. Then you first send the before-rows template, then generate the rows and send them immediately, then the after-rows template. Then you will have only one block/row in memory instead of the whole table.

Most valuable thing for a developer: being able to show you can convert requirements into working and maintainable software.

Prevent web2py from caching?

web2py does cache your code, except for Google App Engine (for speed). That is not the problem. If you you edit code in models, views or controllers, you see the effect immediately. The problem may be modules; if you edit code in modules you will not see the effect immediately, unless you import them with local_import('module', reload=True), or by restarting web2py. Is that is also not your problem, then your browser is caching something. Please bring up this question to the web2py mailing list as we can help more. P.S. If you are using the latest web2py it no longer comes with cherrypy. The built-in web server is called Rocket.

I'm working with web2py and for some reason web2py seems to fail to notice when code has changed in certain cases. I can't really narrow it down, but from time to time changes in the code are not reflected, web2py obviously has the old version cached somewhere. The only thing that helps is quitting web2py and restarting it (i'm using the internal server). Any hints ? Thank you !

I use the middleware because this way I don't have to change the app's code. If I want to migrate my app to other hosting servers, I only need to modify the middleware without affecting other parts. Security is not an issue because on WebFaction you can trust what comes in from the front end server.

If more resources in your computing department are a no go, you're going to have to consider breaking down your data set into manageable chunks before you do any work on it, ad reduce the results down into a meaningful set. More resources from IT would be the way to go. Good luck ! Ben

Many of these answers are now outdated. :) In today's devappserver, use --logs_path=LOGS_FILE if you want to log to a file (in its native sqlite database format). Or as suggested in a comment, simply pipe the output if that's too complicated. Since there's a log API, it actually now stores log entries in a file in --storage_path if not set. I have noticed a few bugs myself, though. (I'll assume they don't exist now, it's been a while since I used this.)

GoogleAppEngineLauncher can display the local log file of my app while it is running on my Mac during development. However, I can't change the font size there so I would like to use the tail command to watch the log file myself. It's a shame but I can't find the log files. They are not under /var/log/, ~/Library/Logs or /Library/Logs. Do you know where they are? (Maybe there are no physical files, just the stdout of the python development environment and so the log is only available in the launcher application.)

You can run an django application in 20 mb memory easily. probably a django application will use less memory than 20mb. I want to advise you to check webpy and cherrypy but I'm big fan of django. if you have 20 mb memory to run application, django will give you everythig it has.

I'm looking for some recommendations for a python web application. We have some memory restrictions and we try to keep it small and lean. We thought about using WSGI (and a python webserver) and build the rest ourself. We already have a template engine we'd like to use, but we are open for some suggestions regarding the whole request handling (the controller). The application has to run in a single process and the requests have to be processed with multiple threads. We've looked at django, but we are a not sure if it fits into our memory budget. Your feedback is very welcome! Cheers, Reto

Suggestions for a pluggable task framework in Django

I would make an app with a very abstract definition of a Task model. The Task model might contain properties for: the input arguments, the function to run, the time that the task was submitted, the time that the task has been actually running, and the result (which would be something like a singleton Task.NotFinished until finished). You could consider using twisted to run the tasks because: twisted has a well designed and tested implementation of asynchronous tasks; and you could run the tasks on other processors or machines.

I am developing a website which is aimed at being a GUI for several image processing algorithms (referred to as 'tasks'). At the moment, only one of these algorithms is finished, but there are more to come (which will have a similar, but not quite the same, workflow) Basically, the algorithm works as follows (not that it matters a lot, but just for the sake of clarity): 1) Enter some parameters and an input image 2) run algorithm part one --algorithm runs-- 3) review an interim result 4) edit the parameters if needed, and go to 2. 5) run algorithm part two --algorithm runs-- 6) review the result 7) adjust some of the interim results if needed, and go to 5 8) all done I expect some of the additional tasks to have a rather similar work flow, though it is perfectly possible that they won't. So, the easy way to implement this would be to create a separate django application for each algorithm. However, I'd like to be able to browse through a sorted list (by time of completion) of completed tasks, and for each of these task display a summary (name, description, start time, thumbnail). Is there anyone that can provide me with some suggestions on how I can implement this? I'd like to keep it as simple as possible, so additional task can be 'plugged' in as easy as possible.

Producing a static HTML site from XML content

I would go with the PHP option. The reason being is that when the XML changes your site content "should" automatically change without you having to touch your PHP code. Creating a Python script to generate lots of static pages just seems like a bad idea to me and with javascript you will have your cross-browser headaches (unless you are using a framework maybe). Use the server side languages for these kind of tasks, it is what they were made for.

I have a long document in XML from which I need to produce static HTML pages (for distribution via CD). I know (to varying degrees) JavaScript, PHP and Python. The current options I've considered are listed here: I'm not ruling out JavaScript, so one option would be to use ajax to dynamically load the XML content into HTML pages. Edit: I'd use jQuery for this option. Learn some basic XSLT and produce HTML to the correct spec this way. Produce the site with PHP (for example) and then generate a static site. Write a script (in Python for example) to convert the XML into HTML. This is similar to the XSLT option but without having to learn XSLT. Useful information: The XML will likely change at some point, so I'd like to be able to easily regenerate the site. I'll have to produce some kind of menu for jumping around the document (so I'll need to produce some kind of index of the content). I'd like to know if anyone has any better ideas that I haven't thought of. If not, I'd like you to tell me which of my options seems the most sensible. I think I know what I'm going to do, but I'd like a second opinion. Thanks.

Go with what you are most comfortable with. If it's straightforward you could use (for example) php to generate a page and then use a command line script (in python or php) to create cached files for you.

If you have easy_install, or better yet pip installed, should be as easy as: easy_install/pip install virtualenv mkdir django1.2 virtualenv django1.2 This will put the python binary in a bin folder inside the django1.2 folder. Just use that python binary, and you've got a nice little self-contained environment. You can then install easy_install/pip into that environment, and then install django 1.2 as well, and hack away.

This is what ssh-copy-id is for. It deploys your public key onto a machine for you. Key management isn't something I'd suggest putting into code/VCS. Each user needs to setup their keys so that the local ssh client knows to use them. We use Fabric as well, but it only uses the key that the ssh config is already telling it to.

Django Inlines user permissions + view only - permissions issues

python,django,permissions,inlines

If I want a read-only version of what's in the admin, I just write some normal Django views and keep them out of the admin. I don't think the kind of thing you're talking about (allowing changes to an object but not its inlines) is really supported by the admin. Don't get me wrong: the admin is very flexible and useful, but it's not intended to do everything for you. The only way I see you being able to have this much control in the admin is to not inline A. "If you don't trust U, just deny him access to the admin area all together". Kind of a stupid doctrine. Not really, when you consider that the admin isn't intended to have the required level of security hardening to guarantee that fine-grain level of access control. There are many, many places in the admin, due to its open and extensible nature, where bugs can lurk (usually in user-written code) that can be exploited by bad actors. This is why untrusted users should always see all admin URLs return 404. Anyway, when access control requirements are that fine-grained, it becomes unlikely that a general (i.e. django.contrib) solution will fit.

I'm not sure if this is a bug or I'm just missing something (although I have already parsed the documentation about inlines), but: Let's say I have a model A. Model A is an inline of model B. User U has full access to model B, but only change permissions to model A (so, no add, nor delete). However, when editing model B, user U can still see the "Add another A" link at the bottom, although U hasn't add permissions for that respective model. What's wrong? Why does that link keep on showing? My logic says that if U does not have permissions to add A, the link shouldn't appear anymore. Also, ideally, I would like to give U only view rights to model A (so no add, delete or change - only view), but I've read about that (strange, if you ask me) philosophy according to which "If you don't trust U, just deny him access to the admin area all together". Kind of a stupid doctrine. Right now, I'm trying to simulate this 'view only permissions' by leaving U with just change rights and set all fields as read only. But I think this is kind of a stupid approach and may also cause problems like the permissions thing above... How does an average Django programmer like me achieve view-only permissions, and most of all how should I get rid of the "Add another A" link at the bottom of the admin edit form? Thanks in advance!

I am about to begin a project where I will likely use PyQt or Pyside. I will need to interface with a buggy 3rd party piece of server software that provides C++ and Java APIs. The Java APIs are a lot easier to use because you get Exceptions where with the C++ libraries you get segfaults. Also, the Python bindings to the Java APIs are automatic with Jython whereas the Python bindings for the C++ APIs don't exist. So, how would a CPython PyQt client application be able to communicate with these Java APIs? How would you go about it? Would you have another separate Java process on the client that serializes / pickles objects and communicates with the PyQt process over a socket? I don't want to re-invent the wheel... is there some sort of standard interface for these types of things? Some technology I should look into? RPC, Corba, etc? Thanks, ~Eric

I have a relatively extensive sqlite database that I'd like to import into my Google App Engine python app. I've created my models using the appengine API which are close, but not quite identical to the existing schema. I've written an import script to load the data from sqlite and create/save new appengine objects, but the appengine environment blocks me from accessing the sqlite library. This script is only to be run on my local app engine instance, and from there I hope to push the data to google. Am I approaching this problem the wrong way, or is there a way to import the sqlite library while running in the local instance's environment?

If it is your basics in OOPS that you wish to strengthen, Java is a good option(provided you know c++ or any other non-web-based language which supports OOPS). However, if you are looking towards web-development, Python should be your best option. Yes, Python is a good option Yes, Django is a very good web application framework(and they have awesome documentation and tutorials put up at their site) To learn Python I definitely recommend reading "The Python Cookbook" cover-to-cover. Its fun, and covers some very important concepts. However, there really is no substitute for the standard python documentation. Its well written, but it might take a while through a major portion of it. Using it as just reference material is also a fine idea. Well I have seen domains which allow Django to be hosted; also you should try out the GAE(google app engine) once you are comfortable with django. Its a great place to host your apps.

I'm using python for my shopping cart class which has a list of items. When a customer wants to edit an item, I need to pass the JavaScript front-end some way to refer to the item so that it can call AJAX methods to manipulate it. Basically, I need a simple way to point to a particular item that isn't its index, and isn't a reference to the object itself. I can't use an index, because another item in the list might be added or removed while the identifier is "held" by the front end. If I were to pass the index forward, if an item got deleted from the list then that index wouldn't point to the right object. One solution seems to be to use UUIDs, but that seems particularly heavyweight for a very small list. What's the simplest/best way to do this?

A UUID seems perfect for this. Why don't you want to do that? Do the items have any sort of product_id? Can the shopping cart have more than one of the same product_id, or does it store a quantity? What I'm getting at is: If product_id's in the cart are unique, you can just use that.

I have intermediate experience with Java. As of right now, I am leaning towards Python, but I just wanted to make sure, I am making the right choice. I find myself limited with books available on asp.net web developments. I am aware that there is the storefront example on the official asp.net site. However, that tutorial was a little hard for me to follow. I've done a research around and was hoping python could be my next available choice. There are more tutorials available online for Python anyways. What do you think?

Identifying if a data is RSS or HTML on python

python,html,rss

Filetypes should generally be determined out-of-band. eg. if you are fetching the file from a web server, the place to look would be the Content-Type header of the HTTP response. If you're fetching a local file, the filesystem would have a way of determining filetype—on Windows that'd be looking at the file extension. If none of that is available, you'd have to resort to content sniffing. This is never wholly reliable, and RSS is particularly annoying because there are multiple incompatible versions of it, but about the best you could do would probably be: Attempt to parse the content with an XML parser. If it fails, the content isn't well-formed XML so can't be RSS. Look at the document.documentElement.namespaceURI. If it's http://www.w3.org/1999/xhtml, you've got XHTML. If it's http://www.w3.org/1999/02/22-rdf-syntax-ns#, you've got RSS (of one flavour). If the document.documentElement.tagName is rss, you've got RSS (of a slightly different flavour). If the file couldn't be parsed as XML, it could well be HTML (or some tag-soup approximation of it). It's conceivable it might also be broken RSS. In that case most feed tools would reject it. If you need to still detect this case you'd be reduced to looking for strings like <html or <rss or <rdf:RSS near the start of the file. This would be even more unreliable.

A task is removed from the queue when it executes if and only if it returns an HTTP 200 response. For any other response, it will be retried until it successfully executes. As David's answer indicates, they can also be manually removed.

Python 2.6 + PIL + Google App Engine issue

How did you install PIL? If I remember correctly, I had to install it via MacPorts to get the App Engine SDK to recognize that it was installed. You should probably install Python 2.5 and use that, while you're at it, since that is the Python version that App Engine uses and developing against 2.6 locally could potentially lead to surprising issues when you deploy your app.

You cannot use PIL with Appengine; it uses C extensions and won't run in the sandbox environment. You do need to have PIL installed on your local machine to use the images API in dev_appserver, because the SDK version of the images API itself uses PIL, but this doesn't mean you can use all of PIL through the images API; the images API is fairly limited. Additionally, it's a good idea to use Python 2.5 for development, as the production environment uses version 2.5.2 and not all Python 2.6 syntax will work in production (notably "except FooError as bar"), and the purpose of the development server is to test that your code will work right in production.

I'd use Apache log4cxx or Apache log4j. It's Efficient. It has Logger hierarchies to modularize your logs. It's proven tecnology for a while now. Currently, appenders exist for the console , files , GUI components, remote socket servers, NT Event Loggers , and remote UNIX Syslog daemons. It is also possible to log asynchronously. How can I support distributed logging? With remote socket servers appenders for example.

python,django,cgi,web-frameworks

A web application framework is independent of the actual HTTP server in use. The server passes an application written using it the requests, and it cranks some gears and spits out a response, which is sent back to the HTTP server. Django has 3 popular connectors to the HTTP server: WSGI, FastCGI, and mod_python. These are all explained... somewhere here, so I'll not repeat information that can easily be discovered.

Basically the functions of any framework are:- make sure that you do not have to do the repetitive tasks. make it easy for you to re-use and modularize they provide a layer of abstraction(which in most cases, makes you more productive) So, Django is a web application framework; naturally it satisfies all three conditions above. If you are interested in cgi programming using Python you should`nt be looking at Django. On the other hand, if you are looking for options for web-development, then django certainly is a good option while manual cgi programming is not.

A web application framework like Django replaces CGI by spawning its own processes and handling requests from a web server. They also provide tools for simplifying html by creating templates, partial templates, helpers etc. If you don't have full control over your server, your host will need to install it for you.

Django Barcode for store sales

2,887,309

2,820

django,vb6,python

If your definition of barcode functionality is the ability to read and write barcodes, you should keep in mind two things. Barcodes are actually read by barcode readers, and from the computers' point of view they are just input devices, just like keyboards. When the reader reads a barcode, it just "types" it in, character by character. Usually it's configurable what the reader sends after the code, tab or enter are quite common options. Enter is the easiest to deal with. There's nothing special in writing barcodes, it's just text with a special font, with *-characters before and after the code. Handling barcodes doesn't really have much to do with Django. Some tricks are required to get it done within browsers, but these would apply if you were doing it in RoR, .net or whatever: Handling barcodes from a web app is quite straightforward. A text input is needed and a bit of javascript to make sure the input has focus, and to trigger action when a barcode has been read. Printing barcodes is not very hard either, just use css3 embedded fonts. If that's too cutting edge, you can always create images of the barcodes server-side, and it'll work with any browser.

java,python,huffman-code

Huffman code doesn't care about characters, it cares about symbols. Generally, it is used to encode the alphabet / other single characters, but can very easily be generalized to encode strings of characters. Basically, you would just take an existing implementation and allow symbols to be strings rather than characters. A leaf node would then correspond to a list of strings.

There is probably some code somewhere. But this sounds like a parsing and tokenising question. One of the first questions I would be answering is how many unique pairs are you dealing with. Huffman encoding works best with small numbers of tokens. For example, the 101 characters on your keyboard. But if your two characters can be anything, you are now expanding the maximum number of characters massively.

I don't think you're likely to find such a thing. Like all the other fast python template engines, Mako achieves its speed by compiling your template into python code and then executing it. An exception will divert execution out of your template's code, so by the time one is raised, that template will have no way of displaying it (or doing anything else for that matter). As an alternative, I suggest putting your template rendering code inside a try block, and rendering any caught exceptions with a separate template used specifically for that purpose.

You're not asking about sessions, you're asking about requests. What you want is known as throttling. However, it would be quite difficult to do it inside the app, because Apache manages multiple processes and threads, so you'd need some external process to keep track of these in order to enable the throttling. Basically, this sort of thing is best done within Apache itself, by something like mod_throttle.

I'm learning about metaclasses in Python. I think it is a very powerful technique, and I'm looking for good uses for them. I'd like some feedback of good useful real-world examples of using metaclasses. I'm not looking for example code on how to write a metaclass (there are plenty examples of useless metaclasses out there), but real examples where you have applied the technique and it was really the appropriate solution. The rule is: no theoretical possibilities, but metaclasses at work in a real application. I'll start with the one example I know: Django models, for declarative programming, where the base class Model uses a metaclass to fill the model objects of useful ORM functionality from the attribute definitions. Looking forward to your contributions.

The best thing I've been able to find is using if request.path_info.startswith('...') to skip over the middleware by just returning the request. Now, you could create middleware just for the sake of skipping and then inherit that. Maybe you could do something even simpler and save that list in your settings.py and then skip all those. If I'm wrong in any way, let me know.

In Django there is a settings file that defines the middleware to be run on each request. This middleware setting is global. Is there a way to specify a set of middleware on a per-view basis? I want to have specific urls use a set of middleware different from the global set.

Django URL resolving infrastructure stops working

python,django,fastcgi,django-urls

Django has a odd behaviour when matching urls in a environment that isn't under debug mode. For example, with DEBUG=False, Django will ignore urls such as: url(r'^', include('someapp.urls')), specifically in the case above, you could let the string empty: url(r'', include('someapp.urls')), In other words, check your regexes. Can you put your urls.py here to be analyzed?

We recently launched a new Django-powered website, and we are experiencing the oddest bug: The site is running under Apache with mod_fastcgi. Everything works fine for a while, and then the URL tag and reverse() functionality stops working. Instead of returning the expected URL, they return "". We haven't noticed anything in Apache's log file; there are no errors being generated by Django. And (the kicker) the problem only occurs in production mode; we can't reproduce it when DEBUG=True. Any thoughts on where we should be looking for the problem? Update: It turned out to be a problem with settings.LANGUAGES, although we haven't determined exactly why that broke things.

This has happened to me before. Normally it's due to a 'broken' urls.py file. There are two things that make this kind of bug really hard to fix: It could be the urls.py file in any of the apps that breaks the reverse() function, so knowing that reverse() breaks for app X doesn't mean the error is in that particular application's urls.py. Django won't even notify you of errors in the urls.py file, unless you somehow manage to crash the site by doing something really, really nasty in the urls.py file. Debugging: The way I go around fixing this is by manually disabling all applications (just comment out their line in INSTALLED_APPS) and checking reverse() works. If it still works, then I enable the next app, until it breaks. I know, very rudimentary stuff, but it works :)

Is there a straightforward way to do this? I'm looking at the 2.5 and 2.6 docs for "strftime()" and there doesn't seem to be a formatting option there for this case. Should I be using something else? Feel free to include any other time-formatting tips that aren't obvious from the docs. =)

No: the "plugin" you mention runs in the user's browser, your server-side script (Python or otherwise) runs on the server, a completely different proposition. This relates to your other recent question about a server-side script accessing information on your desktop: your client machine tends to be very protected against possibly malicious server-side apps (never enough, but everybody keeps trying to make it more and more protected these days).

Loops works too. With this i can send pretty much anything, like package of users id, if it is simple data. But soon i will start sending whole files, maybe xml or executables. Simple server with files is no an option because i want sending files from client too. I was thinking about serialization but i don't know it is the best solution, but if it is i will love some tips from stackoverflow community. EDIT: I added django to question and chose http.

Methods of sending web-generated config files to servers and restarting services

It really depends what you're intending to do, as the question is a little vague. The other answers cover the tools available; choosing one over the other comes down to purpose. Are you intending to manage servers, and services on those servers? If so, try Puppet, CFEngine, or some other tool for managing server configurations. Or, more specifically, are you looking for a deployment/buildout tool that talks to servers? So that you can type in something along the lines of "mytool deploy myproject", and have your project propagate to all the servers? In which case, fabric would be the tool to use. Generally a good configuration will consist of both anyway... but for what it's worth, from the sound of it (managing DHCP/network/etc.), Puppet's the way to go.

I'm thinking about sending it through scp and invoking reload command to services through ssh.

When using SQL Alchemy for abstracting your data access layer and using controllers as the way to access objects from that abstraction layer, how should joins be handled? So for example, say you have an Orders controller class that manages Order objects such that it provides getOrder, saveOrder, etc methods and likewise a similar controller for User objects. First of all do you even need these controllers? Should you instead just treat SQL Alchemy as "the" thing for handling data access. Why bother with object oriented controller stuff there when you instead have a clean declarative way to obtain and persist objects without having to write SQL directly either. Well one reason could be that perhaps you may want to replace SQL Alchemy with direct SQL or Storm or whatever else. So having controller classes there to act as an intermediate layer helps limit what would need to change then. Anyway - back to the main question - so assuming you have these two controllers, now lets say you want the list of orders for a certain set of users meeting some criteria. How do you go about doing this? Generally you don't want the controllers crossing domains - the Orders controllers knows only about Orders and the User controller just about Users - they don't mess with each other. You also don't want to go fetch all the Users that match and then feed a big list of user ids to the Orders controller to go find the matching Orders. What's needed is a join. Here's where I'm stuck - that seems to mean either the controllers must cross domains or perhaps they should be done away with altogether and you simply do the join via SQL Alchemy directly and get the resulting User and / or Order objects as needed. Thoughts?

I was playing with Goole App Engine Task Queue API to learn how to use it. But I couldn't make it trigger locally. My application is working like a charm when I upload to Google servers. But it doesn't trigger locally. All I see from the admin is the list of the tasks. But when their ETA comes, they just pass it. It's like they runs but they fails and waiting for the retries. But I can't see these events on command line. When I try to click "Run" on admin panel, it runs successfuly and I can see these requests from the command line. I'm using App Engine SDK 1.3.4 on Linux with google-app-engine-django. I'm trying to find the problem from 3 hours now and I couldn't find it. It's also very hard to debug GAE applications. Because debug messages do not appear on console screen. Thanks.

If your Python webapp is running inside a browser on the client machine, I don't see any other way than manually for the user. Some workarounds you might want to investigate: if you web app is installed on the client machine, you will be able to connect directly to the printer, as you have access to the underlying OS system. you could potentially create a plugin that can be installed on the browser that does this for him, but I have no clue as how this works technically. what is it that you want to print ? You could generate a pdf that contains everything that the user needs to print, in one go ?

Otherwise translating a django urlconf to routes manually is doable. Routes is as flexible as django urlconfs when it comes to defining urlpatterns.

I am developing a small testing website using Django 1.2 in Aptana Studio build 2.0.4.1268158907. I have a Django project that I test by running the command "runserver 8001" on my project. This command runs the project on a small server that comes with Django. However the problem arises that every time I run this command Aptana opens two instances of the process "python.exe". Upon terminating the command only one of these instances is ended. The other process continues to run and use memory. My server is not online, and the process doesn't seem to do anything that I can find. This happens every time i run the runserver command on my project and therefore more and more python.exe instances will open up through my development period. Any help discovering either the purpose of this extra python.exe or a way to prevent it from opening would be much appreciated.

Django or Drupal, which one should I use that suits best my needs?

I've built several sites on Drupal and Django, my conclusion is: if you need to create something similar to the standard drupal (or Ubercart) feature-set, you don't have much time for development, and you don't expect hight load pressure on a site - you should pick Drupal. But if you do need to create something more or less custom (no drupal modules already available) you should go with Django - it is quicker and more pleasurable to implement custom complex features using Django. For example if my goal is to implement a second stackoverflow, I'll prefer Django because it will be extremely complicated to implement this badge-based rating system with Drupal. P.S. Studying Python (and Django) is an investment in your future, I think. You'll never be able to implement something similar to DropBox using drupal and php, although it could be implemented with java - but java is not so good from development speed perspective.

Drupal and Django doesn't make for a good comparison, as they are quite different. If all you need is a simple website with a CMS and Paypal, I would go for Drupal. Drupal's strength compared Django is it's many modules (modular system), which most of the time can get you where you want. Drupal is also extremely flexible, and you can change almost anything from within your own code, and there is a huge demand for Drupal developers. You can also let site builders create content, display content and much from from within the AI. Django on the other hand, is more simple and structured. It's based a lot more on code, making it fast and easy to develop something, but hard for non coders to change certain things. For sites that require a lot of custom coding, I usually prefer working with Django. Python is also a more structured programming language than PHP (IMO), and it's easier to make more maintainable code.

I've been developing with Django for more than 2 years and have built a couple of Drupal sites in the meantime (per client's specific request to use Drupal). My conclusions are the following: Even for a smaller site I would have done it quicker building it from scratch with django (or maybe even PHP) for a simple reason, writing code for me is faster than hunting through drupal's unorganized mess of menus and options, or hunting on the web for a module that implements hack X to enable feature Y. Migrating a site from development to production with Drupal is a big PITA. You can forget about using a VCS tool. All your work is in in the MySQL dump (including configurations, programming logic, views etc.), a few hacked up modules and the uploaded files.

My Python team has been using Dojo on the client-side for a few years now, and we settled on CherryPy as our server-side about a year ago, and are pretty pleased with it. It's fairly minimal as web servers go, and enables us to customize the server behavior as needed. Initially we looked at Django and Turbogears as well, but we needed to do some things vis-a-vis user authentication, DB tuning, and templating that didn't really fit well in the "full stack" frameworks, so we've rolled our own stack instead. As for why Dojo and Python go well together, I can only speak for myself, but they seem to have a similar "feel" to me, so I can move from writing code on the server-side and client-side without having to make too much of a cognitive shift.

Why not still keep it in a database? Your remote REST store is all well and funky, but if you've got local data, there's nothing (unless there's spec saying so) to stop you storing some stuff in a local db. Doesn't have to be anything v glamorous - could be sqlite, or you could have some fun with redis, etc.

I'm building a website that doesn't require a database because a REST API "is the database". (Except you don't want to be putting site-specific things in there, since the API is used by mostly mobile clients) However there's a few things that normally would be put in a database, for example the "jobs" page. You have master list view, and the detail views for each job, and it should be easy to add new job entries. (not necessarily via a CMS, but that would be awesome) e.g. example.com/careers/ and example.com/careers/77/ I could just hardcode this stuff in templates, but that's no DRY- you have to update the master template and the detail template every time. What do you guys think? Maybe a YAML file? Or any better ideas? Thx

No. You can only do a LOT better. Awesome, popular. Supported by best hosters like Mediatemple. No. You can just change 'mysql' to 'postgresql' or 'sqlite' in your settings.py. NO! Python would never give you the right to mix up everything in one file and make the shittest shit in the world. Templates, static server. Django is a Model-Template-View framework, great for any applications, from small to huge. PHP works fine only with small apps. Yeah, PHP == Personal Home Page, lol. P.S. Also you can minify your CSS and JS. And compile to one single file (one js, one css). All with django-assets. And yeah, there's a lot more reusable Django apps (for registration, twi/facebook/openid auth, oembed, other stuff). Just search Bitbucket and Github for "django". No need to reinvent a bicycle, like you do with PHP.

Here's my background: Decent experience with PHP/MySql. Beginner's experience with OOP Why I want to learn Python Django? I gave in, based on many searches on SO and reading over some of the answers, Python is a great, clean, and structured language to learn. And with the framework Django, it's easier to write codes that are shorter than with PHP Questions Can i do everything in Django as in PHP? Is Django a "big" hit in web development as PHP? I know Python is a great general-purpose language but I'm focused on web development and would like to know how Django ranks in terms of web development. With PHP, PHP and Mysql are VERY closely related, is there a close relation between Django and Mysql? In PHP, you can easily switch between HTML, CSS, PHP all in one script. Does Python offer this type of ease between other languages? Or how do I incorporate HTML, CSS, javascript along with Python?

How to transition from PHP to Python Django?

Can i do everything in Django as in PHP? Always Is Django a "big" hit in web development as PHP? Only time will tell. With PHP, PHP and Mysql are VERY closely related, is there a close relation between Django and Mysql? Django supports several RDBMS interfaces. MySQL is popular, so is SQLite and Postgres. In PHP, you can easily switch between HTML, CSS, PHP all in one script. That doesn't really apply at all to Django. Or how do I incorporate HTML, CSS, javascript along with Python? Actually do the Django tutorial. You'll see how the presentation (via HTML created by templates) and the processing (via Python view functions) fit together. It's not like PHP.
