Django shortcut functions
|
|
=========================
|
|
|
|
The package ``django.shortcuts`` collects helper functions and classes that
|
|
"span" multiple levels of MVC. In other words, these functions/classes
|
|
introduce controlled coupling for convenience's sake.
|
|
|
|
``render_to_response``
|
|
======================
|
|
|
|
``django.shortcuts.render_to_response`` renders a given template with a given
|
|
context dictionary and returns an ``HttpResponse`` object with that rendered
|
|
text.
|
|
|
|
Example::
|
|
|
|
from django.shortcuts import render_to_response
|
|
r = render_to_response('myapp/template.html', {'foo': 'bar'})
|
|
|
|
This example is equivalent to::
|
|
|
|
from django.http import HttpResponse
|
|
from django.template import Context, loader
|
|
t = loader.get_template('myapp/template.html')
|
|
c = Context({'foo': 'bar'})
|
|
r = HttpResponse(t.render(c))
|
|
|
|
``get_object_or_404``
|
|
=====================
|
|
|
|
``django.shortcuts.get_object_or_404`` calls ``get()`` on a given model
|
|
manager, but it raises ``django.http.Http404`` instead of the model's
|
|
``DoesNotExist`` exception.
|
|
|
|
``get_list_or_404``
|
|
===================
|
|
|
|
``django.shortcuts.get_list_or_404`` returns the result of ``filter()`` on a
|
|
given model manager, raising ``django.http.Http404`` if the resulting list is
|
|
empty.
