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.
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.
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).
Context processors
TemplateResponse uses RequestContext
which means that callables defined in
TEMPLATE_CONTEXT_PROCESSORS may overwrite template
variables defined in your views. For example, if you subclass
DetailView and
set context_object_name to user, the
django.contrib.auth.context_processors.auth context processor
will happily overwrite your variable with current user.
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.
If template_name is specified, the default implementation will
return a list containing template_name (if it is specified).
