Is this possible in Django?\n\nEDIT: My solution (based on Saurabh Goyal’s answer):\n\n\nAdd a new model to your models.py, something like this:\n\nclass ShareKey(models.Model):\n location = models.TextField() # absolute path\n token = models.CharField(max_length=40, primary_key=True)\n creation_date = models.DateTimeField(auto_now_add=True)\n expiration_seconds = models.BigIntegerField()\n data = PickledObjectField() # custom sharing data\n\n\n(The data field is optional, and requires django-picklefield).\nIn your views.py, add a decorator function like this:\n\ndef allow_shares(view_func):\n def sharify(request, *args, **kwargs):\n shared = kwargs.get('__shared', None)\n if shared is not None:\n if '__shared' not in view_func.func_code.co_varnames[:view_func.func_code.co_argcount]:\n del kwargs[\"__shared\"]\n return view_func(request, *args, **kwargs)\n else: return login_required(view_func)(request, *args, **kwargs)\n return sharify\n\n\nThis decorator allows a view to require a login, unless the page is shared.\nDecorate any views you want to be shareable with @allow_shares.\nAdd a new Exception subclass, SharifyError, like this:\n\nclass SharifyError(Exception):pass\n\nAlso in views.py, add a view to resolve the shared URLs, like this:\n\ndef sharedPage(request, key):\n try:\n try:\n shareKey = ShareKey.objects.get(pk=key)\n except: raise SharifyError\n if shareKey.expired: raise SharifyError\n func, args, kwargs = resolve(shareKey.location)\n kwargs[\"__shared\"] = True\n return func(request, *args, **kwargs)\n except SharifyError:\n raise Http404 # or add a more detailed error page. This either means that the key doesn’t exist or is expired.\n\nAdd a url to urls.py, like this:\n\nurlpatterns = patterns('',\n # ...\n url(r'^access/(?P<key>\\w+)$', views.sharedPage, name=\"sharedPage\"),\n # ...\n)\n\nFinally, add URLs to create a shared link, and implement the view like this:\n\n# in imports\nfrom django.utils.crypto import get_random_string\n\ndef createShare(request, model_id):\n task = MyModel.objects.get(pk=model_id)\n key = ShareKey.objects.create(pk=get_random_string(40),\n expiration_seconds=60*60*24, # 1 day\n location = task.get_absolute_url(),\n )\n key.save()\n return render(request, 'share.html', {\"key\":key});\n\n\n\n(Your share.html template should look something like this):\n\n{% extends 'base.html' %}\n{% block content %}\n<h1>Sharing link created.</h1>\n<p>The link is <a href=\"{{ base_url }}{% url 'taskShared' key.pk %}\">{{ base_url }}{% url 'taskShared' key.pk %}</a>. It will be valid until {{ key.expiration_date|date:\"l, N dS\" }} at {{ key.expiration_date|time:\"g:i a\" }}.</p>\n{% endblock %}\n\n\nThis will require users to login to view the decorated pages unless they have entered a key." ]

Another .cpp file in the application uses these variables to instantiate another object and needs them to be instantiated to not throw a null-pointer exception. My solution so far was simply to drag-drop (XCode simplicity) the first file over the second one in the build-phase order. It works fine now, but I have a feeling that it is not the optimal solution, and that there is something fundamentally wrong with my code if I need to organise the compile order manually for the application to run properly.\n\nShould I never instantiate something outside of functions, or what is the golden rule? Thanks.\n\nEDIT: An example as requested.\nThe problem lies in a Observer/Event system.\nIn a source-file I do this:\n\nTrigger* mainMenu_init = new Trigger(std::vector<Event*> {\n // Event(s):\n event_gameInit,\n\n}, [](Event* e) {\n // Action(s):\n std::cout << \"Hello World\" << std::endl;\n\n});\n\n\nIn the trigger's constructor the Event is asked to add is as an observer:\n\nfor(Event* event : events)\n event->addObserver(this);\n\n\nBUT, the events are just external pointers, so if they are not initialised (which they are in another source-file) this initialisation will fail.

[ "Use Data From One SQL Table and Correlate It To Data In Another Table", "First off, I'm doing this for purely educational purposes. I have a Kodi (XBMC) plugin that goes through my TV Show database and stores which episodes have been watched and how many times. I figured out how to use HTML forms to retrieve data (TheTVDB ID number, Season, Episode numbers, and how many times the episode has been played) from my database using PHP. In an attempt to further my knowledge, I'm trying to convert the \"friendly\" show name which is taken by the form, then convert it to the ID number, and use that stored value in another query on a different table in the same database to return the Episode and Season Numbers. \n\nFor example, Friends is ID# 79168. The table tvshows contains columns idShow and titles, whereas the table episode_watched contains columns idShow, season, episode and playCount. After idShow is correlated to title, I would like to output a table with the columns Season and Episode which match the specific playcount and title.\n\nHere's my code: http://pastebin.com/i7Y2ZWpR\n\nThis is the PHP error that I'm getting:\n\n\n Notice: Trying to get property of non-object in\n /usr/share/webapps/pydio/sql.php on line 15\n\n\n0 Results" ]
