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/", 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``.

By default, the generated view will create a new instance of the view class for every request and call its :meth:`dispatch_request` method. If the view class sets :attr:`init_every_request` to ``False``, the same instance will be used for every request. Except for ``name``, all other arguments passed to this method are forwarded to the view class ``__init__`` method. .. versionchanged:: 2.2 Added the ``init_every_request`` class attribute. rrkwargsrcs&ji}t|jfi|SN) view_classr ensure_syncr)r"r)rr viewrrr&is zView.as_view..viewcstjfi|Sr#)rr%r)r"rrrr&rs)rr__name__ __module__r$__doc__rr)clsrrr decoratorr)rr rr&ras_viewTs   z View.as_view) r'r( __qualname__r)r__annotations__rrrr classmethodr,rrrrrs "   rcs8eZdZdZdddfdd Zddddd ZZS) MethodViewaDispatches request methods to the corresponding instance methods. For example, if you implement a ``get`` method, it will be used to handle ``GET`` requests. This can be useful for defining a REST API. :attr:`methods` is automatically set based on the methods defined on the class.
