This module collects helper functions and classes that "span" multiple levels of MVC. In other words, these functions/classes introduce controlled coupling for convenience's sake.

Function Details

[hide private]

_get_queryset(klass)

source code

Returns a QuerySet from a Model, Manager, or QuerySet. Created to make get_object_or_404 and get_list_or_404 more DRY.

get_object_or_404(klass, *args, **kwargs)

source code

Uses get() to return an object, or raises a Http404 exception if the object does not exist.

klass may be a Model, Manager, or QuerySet object. All other passed arguments and keyword arguments are used in the get() query.

Note: Like with get(), an MultipleObjectsReturned will be raised if more than one object is found.

get_list_or_404(klass, *args, **kwargs)

source code

Uses filter() to return a list of objects, or raise a Http404 exception if the list is empty.

klass may be a Model, Manager, or QuerySet object. All other passed arguments and keyword arguments are used in the filter() query.
