Then you can use the assertAllowed() and isAllowed() helpers inside
your controllers and views to check if the current user is allowed
access to perform an action on a resource. You can see this being done
in the following files:
If the user tries to perform an action that they're not allowed access
to perform, a typed exception is thrown, which can then be handled by
an error controller.
Again, I'll try to get some documentation created for this sometime
soon, but in the meantime if you have any questions, please ask.
