It is recommended to define a dynamic ACL as a callable to avoid this ambiguity. See https://github.com/Pylons/pyramid/issues/735. +Bug Fixes +--------- + +- View lookup will now search for valid views based on the inheritance + hierarchy of the context. It tries to find views based on the most + specific context first, and upon predicate failure, will move up the + inheritance chain to test views found by the super-type of the context. + In the past, only the most specific type containing views would be checked + and if no matching view could be found then a PredicateMismatch would be + raised. Now predicate mismatches don't hide valid views registered on + super-types. Here's an example that now works:: + + .. code-block:: python + + class IResource(Interface): + ... + + @view_config(context=IResource) + def get(context, request): + ... + + @view_config(context=IResource, request_method='POST') + def post(context, request): + ... + + @view_config(context=IResource, request_method='DELETE') + def delete(context, request): + ... + + @implementor(IResource) + class MyResource: + ... + + @view_config(context=MyResource, request_method='POST') + def override_post(context, request): + ... + + Previously the override_post view registration would hide the get + and delete views in the context of MyResource -- leading to a + predicate mismatch error when trying to use GET or DELETE + methods. Now the views are found and no predicate mismatch is + raised. + 1.4 (2012-12-18) ================ |
