View

Subclass this class and override :meth:dispatch_request to create a generic class-based view. Call :meth:as_view to create a view function that creates an instance of the class with the given arguments and calls its dispatch_request method with any URL variables.

Attributes

Attribute	Type	Description
methods	`t.ClassVar[t.Collection[str]	None]` = null
provide_automatic_options	`t.ClassVar[bool	None]` = null
decorators	t.ClassVar[list[t.Callable[..., t.Any]]] = []	A list of decorators to apply, in order, to the generated view function. Remember that @decorator syntax is applied bottom to top, so the first decorator in the list would be the bottom decorator.
init_every_request	t.ClassVar[bool] = true	Create a new instance of this view class for every request by default. If a view subclass sets this to False, the same instance is used for every request.
