Add a class-based view mixin for checking if HTTP methods are allowed.
Review Request #9127 — Created Aug. 7, 2017 and submitted
Django's base View class for class-based views performs a check before
dispatching to make sure that the HTTP method in question is allowed,
returning a HTTP 405 if not. While useful, this is too late for more
complex views that are performing other (potentially method-specific)
logic before reaching
This change introduces
CheckRequestMethodViewMixin, which can be
placed at the beginning of the inheritance list to handle the checking
early. It will perform the same checks that
but can be done before any other mixin dispatch methods are invoked.
Unit tests pass.
Made use of this in another change and verified the dispatch handlers
never got called for unsupported HTTP methods.
Fixed ReviewBot complaints.
