Simple mixins

ContextMixin

class 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

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 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).
