def lazy_module(modname, error_strings=None, lazy_mod_class=LazyModule, level='leaf'):
"""Function allowing lazy importing of a module into the namespace. A lazy module object is created, registered in `sys.modules`, and returned. This is a hollow module; actual loading, and `ImportErrors` if not found, are delayed until an attempt is made to access attributes of the lazy module. A handy application is to use :func:`lazy_module` early in your own code (say, in `__init__.py`) to register all modulenames you want to be lazy. Because of registration in `sys.modules` later invocations of `import modulename` will also return the lazy object. This means that after initial registration the rest of your code can use regular pyhon import statements and retain the lazyness of the modules. Parameters modname : str The module to import. error_strings : dict, optional A dictionary of strings to use when module-loading fails. Key 'msg' sets the message to use (defaults to :attr:`lazy_import._MSG`). The message is formatted using the remaining dictionary keys. The default message informs the user of which module is missing (key 'module'), what code loaded the module as lazy (key 'caller'), and which package should be installed to solve the dependency (key 'install_name'). None of the keys is mandatory and all are given smart names by default. lazy_mod_class: type, optional Which class to use when instantiating the lazy module, to allow deep customization. The default is :class:`LazyModule` and custom alternatives **must** be a subclass thereof. level : str, optional Which submodule reference to return. Either a reference to the 'leaf' module (the default) or to the 'base' module. This is useful if you'll be using the module functionality in the same place you're calling :func:`lazy_module` from, since then you don't need to run `import` again. Setting *level* does not affect which names/modules get registered in `sys.modules`. For *level* set to 'base' and *modulename* 'aaa.bbb.ccc':: aaa = lazy_import.lazy_module("aaa.bbb.ccc", level='base') # 'aaa' becomes defined in the current namespace, with # (sub)attributes 'aaa.bbb' and 'aaa.bbb.ccc'. # It's the lazy equivalent to: import aaa.bbb.ccc For *level* set to 'leaf':: ccc = lazy_import.lazy_module("aaa.bbb.ccc", level='leaf') # Only 'ccc' becomes set in the current namespace. # Lazy equivalent to: from aaa.bbb import ccc Returns ------- module The module specified by *modname*, or its base, depending on *level*. The module isn't immediately imported. Instead, an instance of *lazy_mod_class* is returned. Upon access to any of its attributes, the module is finally loaded. Examples -------- Lazily-loaded module numpy True 3.141592653589793 <module 'numpy' from '/usr/local/lib/python/site-packages/numpy/__init__.py'> Lazily-loaded module missing_module True ImportError: __main__ attempted to use a functionality that requires module missing_module, but it couldn't be loaded.

def lazy_callable(modname, *names, **kwargs):
"""Performs lazy importing of one or more callables. :func:`lazy_callable` creates functions that are thin wrappers that pass any and all arguments straight to the target module's callables. These can be functions or classes. The full loading of that module is only actually triggered when the returned lazy function itself is called. This lazy import of the target module uses the same mechanism as :func:`lazy_module`. If, however, the target module has already been fully imported prior to invocation of :func:`lazy_callable`, then the target callables themselves are returned and no lazy imports are made. :func:`lazy_function` and :func:`lazy_function` are aliases of :func:`lazy_callable`. Parameters modname : str The base module from where to import the callable(s) in *names*, or a full 'module_name.callable_name' string. names : str (optional) The callable name(s) to import from the module specified by *modname*. If left empty, *modname* is assumed to also include the callable name to import. error_strings : dict, optional A dictionary of strings to use when reporting loading errors (either a missing module, or a missing callable name in the loaded module). *error_string* follows the same usage as described under :func:`lazy_module`, with the exceptions that 1) a further key, 'msg_callable', can be supplied to be used as the error when a module is successfully loaded but the target callable can't be found therein (defaulting to :attr:`lazy_import._MSG_CALLABLE`); 2) a key 'callable' is always added with the callable name being loaded. lazy_mod_class : type, optional See definition under :func:`lazy_module`. lazy_call_class : type, optional Analogously to *lazy_mod_class*, allows setting a custom class to handle lazy callables, other than the default :class:`LazyCallable`. Returns ------- wrapper function or tuple of wrapper functions If *names* is passed, returns a tuple of wrapper functions, one for each element in *names*. If only *modname* is passed it is assumed to be a full 'module_name.callable_name' string, in which case the wrapper for the imported callable is returned directly, and not in a tuple. Notes ----- Unlike :func:`lazy_module`, which returns a lazy module that eventually mutates into the fully-functional version, :func:`lazy_callable` only returns thin wrappers that never change. This means that the returned wrapper object never truly becomes the one under the module's namespace, even after successful loading of the module in *modname*. This is fine for most practical use cases, but may break code that relies on the usage of the returned objects oter than calling them. One such example is the lazy import of a class: it's fine to use the returned wrapper to instantiate an object, but it can't be used, for instance, to subclass from. Examples -------- Lazily-loaded module numpy array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9]) <module 'numpy' from '/usr/local/lib/python3.5/site-packages/numpy/__init__.py'> See Also -------- :func:`lazy_module` :class:`LazyCallable` :class:`LazyModule` """ |

""" Return True if an object is part of the search index queryset. Sometimes it's useful to know if an object _should_ be indexed. If an object is saved, how do you know if you should push that change to the search index? The simplest (albeit not most efficient) way is to check if it appears in the underlying search queryset. NB this method doesn't evaluate the entire dataset, it chains an additional queryset filter expression on the end. That's why it's important that the `get_search_queryset` method returns a queryset.

The default 'full' strategy simply returns the value of `as_search_document` - thereby replacing the entire document each time. The 'partial' strategy is more intelligent - it will determine whether the fields passed are in the search document mapping, and return a partial update document that contains only those that are. In addition, if any field that _is_ included cannot be automatically serialized (e.g. a RelatedField object), then this method will raise a ValueError. In this scenario, you should override this method in your subclass.
