Définition

class View(builtins.object):

help(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.

See :doc:`views` for a detailed guide.

.. code-block:: python

    class Hello(View):
        init_every_request = False

        def dispatch_request(self, name):
            return f"Hello, {name}!"

    app.add_url_rule(
        "/hello/<name>", view_func=Hello.as_view("hello")
    )

Set :attr:`methods` on the class to change what methods the view
accepts.

Set :attr:`decorators` on the class to apply a list of decorators to
the generated view function. Decorators applied to the class itself
will not be applied to the generated view function!

Set :attr:`init_every_request` to ``False`` for efficiency, unless
you need to store request-global data on ``self``.
