ContextMixin
|
|
------------
|
|
|
|
.. class:: django.views.generic.base.ContextMixin
|
|
|
|
.. versionadded:: 1.5
|
|
|
|
**classpath**
|
|
|
|
``django.views.generic.base.ContextMixin``
|
|
|
|
**Methods**
|
|
|
|
.. method:: get_context_data(**kwargs)
|
|
|
|
Returns a dictionary representing the template context. The keyword
|
|
arguments provided will make up the returned context.
|
|
|
|
The template context of all class-based generic views include a
|
|
``view`` variable that points to the ``View`` instance.
|
|
|
|
.. admonition:: Use ``alters_data`` where appropriate
|
|
|
|
Note that having the view instance in the template context may
|
|
expose potentially hazardous methods to template authors. To
|
|
prevent methods like this from being called in the template, set
|
|
``alters_data=True`` on those methods. For more information, read
|
|
the documentation on :ref:`rendering a template context
|
|
<alters-data-description>`.
|
|
|
|
TemplateResponseMixin
|
|
---------------------
|
|
|
|
.. class:: django.views.generic.base.TemplateResponseMixin
|
|
|
|
Provides a mechanism to construct a
|
|
:class:`~django.template.response.TemplateResponse`, given
|
|
suitable context. The template to use is configurable and can be
|
|
further customized by subclasses.
|
|
|
|
**Methods and Attributes**
|
|
|
|
.. attribute:: response_class
|
|
|
|
The response class to be returned by ``render_to_response`` method.
|
|
Default is
|
|
:class:`TemplateResponse <django.template.response.TemplateResponse>`.
|
|
The template and context of ``TemplateResponse`` instances can be
|
|
altered later (e.g. in
|
|
:ref:`template response middleware <template-response-middleware>`).
|
|
|
|
If you need custom template loading or custom context object
|
|
instantiation, create a ``TemplateResponse`` subclass and assign it to
|
|
``response_class``.
|
|
|
|
.. method:: render_to_response(context, **response_kwargs)
|
|
|
|
Returns a ``self.response_class`` instance.
|
|
|
|
If any keyword arguments are provided, they will be
|
|
passed to the constructor of the response class.
|
|
|
|
Calls :meth:`~TemplateResponseMixin.get_template_names()` to obtain the
|
|
list of template names that will be searched looking for an existent
|
|
template.
|
|
|
|
.. method:: get_template_names()
|
|
|
|
Returns a list of template names to search for when rendering the
|
|
template.
|
|
|
|
If :attr:`TemplateResponseMixin.template_name` is specified, the
|
|
default implementation will return a list containing
|
|
:attr:`TemplateResponseMixin.template_name` (if it is specified).
