     Finally, you can conditionally enable or disable actions on a per-request
     (and hence per-user basis) by overriding :meth:`ModelAdmin.get_actions`.
 
-    This doesn't return any actions if the user doesn't have the "change"
-    permission for the model.

     This returns a dictionary of actions allowed. The keys are action names, and
     the values are ``(function, name, short_description)`` tuples.
