Actions are such a generic concept that it's +simple to reimplement action-like navigation in a different way within +any given application. For example, a module-scope global dictionary +which has keys that are action names, and values which are tuples of +(permission, link). Take that concept and expand on it, and you'll +have some passable actions tool replacement within a single application. + +The `repoze.bfg.viewgroup +<http://svn.repoze.org/repoze.bfg.viewgroup/trunk/>` package provides +some functionality for creating "view groups". Each view in a +viewgroup can provide some snippet of HTML (e.g. a single "tab"), and +views (tabs) which cannot be displayed to the user due to the user's +lack of permissions will be omitted from the group. + |
