ContextMixin
¶django.views.generic.base.
ContextMixin
¶Methods
get_context_data
(**kwargs)¶Returns a dictionary representing the template context. The keyword arguments provided will make up the returned context. Example usage:
def get_context_data(self, **kwargs):
context = super(RandomNumberView, self).get_context_data(**kwargs)
context['number'] = random.randrange(1, 100)
return context
The template context of all class-based generic views include a
view
variable that points to the View
instance.
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 rendering a template context.
TemplateResponseMixin
¶django.views.generic.base.
TemplateResponseMixin
¶Provides a mechanism to construct a
TemplateResponse
, given
suitable context. The template to use is configurable and can be
further customized by subclasses.
Attributes
template_name
¶The full name of a template to use as defined by a string. Not defining
a template_name
will raise a
django.core.exceptions.ImproperlyConfigured
exception.
template_engine
¶The NAME
of a template engine to use for
loading the template. template_engine
is passed as the using
keyword argument to response_class
. Default is None
, which
tells Django to search for the template in all configured engines.
response_class
¶The response class to be returned by render_to_response
method.
Default is TemplateResponse
. The template and context
of TemplateResponse
instances can be altered later (e.g. in
template response middleware).
If you need custom template loading or custom context object
instantiation, create a TemplateResponse
subclass and assign it to
response_class
.
content_type
¶The content type to use for the response. content_type
is passed
as a keyword argument to response_class
. Default is None
–
meaning that Django uses DEFAULT_CONTENT_TYPE
.
Methods
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 get_template_names()
to obtain the list of template names
that will be searched looking for an existent template.
get_template_names
()¶Returns a list of template names to search for when rendering the template. The first template that is found will be used.
If template_name
is specified, the default implementation will
return a list containing template_name
(if it is specified).
