[Grok-dev] defining permissions in a module

[Jan-Wijbrand Kolman]

Hi,


In my application it sorta felt logical to define permissions in one
module and to reuse these permission in the modules of the
application. Something like:

permissions.py:

  import grok
  ...
  ADD_FOO = 'myappprefix.add_foo'
  EDIT_FOO = 'myappprefix.edit_foo'
  ...
  grok.

model.py:

  import grok
  import permissions
  ...
  EditFoo(grok.View):
    ...
    grok.require(permissions.EDIT_FOO)

Now, this only works if the permissions.py module is grokkked *before*
the module.py, which, if they're in the same package is not the case
(due to alphabetical order I guess).

Now, I do not really see a solution to this problem actually. I don't
think the grokkking process can grow a sort of "order resolution"
issues like these (but I'm really not sure).

But at least now you know of this limitation  - or are there actullay
better ways to keep permissions in a central place?


kind regards,
jw
