Django shortcut functions
|

=========================
|

|

.. module:: django.shortcuts

:synopsis:
|
||||
Convience shortcuts that spam multiple levels of Django's MVC stack.
|
||||
|
||||
.. index:: shortcuts
|
||||
|
||||
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.

``django.shortcuts.render_to_response`` renders a given template with a given

|
||||
text.
|
||||
.. function:: render_to_response(template[, dictionary][, context_instance][, mimetype])
|
||||
|

Renders a given template with a given context dictionary and returns an

:class:`~django.http.HttpResponse` object with that rendered text.

``redirect``
|
||||
============
|
||||
|
||||
.. function:: redirect(to[, permanent=False], *args, **kwargs)
|
||||
|
||||
Returns an HttpResponseRedirect to the apropriate URL for the arguments
|
||||
passed.
|
||||
|
||||
The arguments could be:
|
||||
|
||||
* A model: the model's `get_absolute_url()` function will be called.
|
||||
|
||||
* A view name, possibly with arguments: `urlresolvers.reverse()` will
|
||||
be used to reverse-resolve the name.
|
||||
|
||||
* A URL, which will be used as-is for the redirect location.
|
||||
|
||||
By default issues a temporary redirect; pass permanent=True to issue a
|
||||
permanent redirect
|
||||
|
||||
Examples
|
||||
--------
|
||||
|
||||
You can use the :func:`redirect` function in a number of ways.
|
||||
|
||||
1. By passing some object; that object's
|
||||
:meth:`~django.db.models.Model.get_absolute_url` method will be called
|
||||
to figure out the redirect URL::
|
||||
|
||||
def my_view(request):
|
||||
...
|
||||
object = MyModel.objects.get(...)
|
||||
return redirect(object)
|
||||
|
||||
2. By passing the name of a view and optionally some positional or
|
||||
keyword arguments; the URL will be reverse resolved using the
|
||||
:func:`~django.core.urlresolvers.reverse` method::
|
||||
|
||||
def my_view(request):
|
||||
...
|
||||
return redirect('some-view-name', foo='bar')
|
||||
|
||||
3. By passing a hardcoded URL to redirect to::
|
||||
|
||||
def my_view(request):
|
||||
...
|
||||
return redirect('/some/url/')
|
||||
|
||||
This also works with full URLs::
|
||||
|
||||
def my_view(request):
|
||||
...
|
||||
return redirect('http://example.com/')
|
||||
|
||||
By default, :func:`redirect` returns a temporary redirect. All of the above
|
||||
forms accept a ``permanent`` argument; if set to ``True`` a permanent redirect
|
||||
will be returned::
|
||||
|
||||
def my_view(request):
|
||||
...
|
||||
object = MyModel.objects.get(...)
|
||||
return redirect(object, permanent=True)
|
||||
|
||||
``get_object_or_404``
|
||||
=====================
|
||||
|
||||
``django.shortcuts.get_object_or_404`` calls
|
||||
:meth:`~django.db.models.QuerySet.get()` on a given model manager, but it raises
|
||||
``django.http.Http404`` instead of the model's ``DoesNotExist`` exception.
|
||||
.. function:: get_object_or_404(object, *args, **kwargs)
|
||||
|
||||
Calls :meth:`~django.db.models.QuerySet.get()` on a given model manager,
