Simple mixins
ContextMixin
-
class django.views.generic.base.ContextMixin
-
Attributes
-
extra_context
-
New in Django 2.0.
A dictionary to include in the context. This is a convenient way of specifying some simple context in
as_view()
. Example usage:from django.views.generic import TemplateView TemplateView.as_view(extra_context={'title': 'Custom Title'})
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().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 theView
instance.Use
alters_data
where appropriateNote 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
-
class 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 adjango.core.exceptions.ImproperlyConfigured
exception.
-
template_engine
-
The
NAME
of a template engine to use for loading the template.template_engine
is passed as theusing
keyword argument toresponse_class
. Default isNone
, 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 isTemplateResponse
. The template and context ofTemplateResponse
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 toresponse_class
.
-
content_type
-
The content type to use for the response.
content_type
is passed as a keyword argument toresponse_class
. Default isNone
– meaning that Django usesDEFAULT_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 containingtemplate_name
(if it is specified).
