martian CLASS_OR_MODULE scope directive information is not inherited between modules

[Jan Wijbrand Kolman]

Consider a module a.py:

  import grok

  grok.context(SomeContext)

  class AContextView(grok.View):
    pass

and module b.py:

  import grok
  import a

  class BContextView(a.AContextView):
    pass

It is expected that since BContextView subclasses AContextView, the context for the BContextView class is SomeContext too (the grok.context directive has a CLASS_OR_MODULE scope).

That is currently not how the CLASS_OR_MODULE scope is implemented. Currently it will look for a context in the b.py module in the case where no grok.context directive is used on the class level - and in this example it means no context can be found for BContextView.

The solution for CLASS_OR_MODULE scope directives, in case the directive cannot be found on the component or the component's module, would be to recursively loop through the __mro__ of the component class and apply the directive.

This has been fixed in the martian refactoring for a while now already, the issue was never updated. Closed now.
