Rails CanCan: Doesn't CanCan assume I can :read if I can :update?
Category : Programming Languages

This works for an authorize! call


can [:read,:update], brand

but CanCan::AccessDenied is thrown when the line in the Ability class is changed to:


can :update, brand

brand is not nil.


If I can :update something, shouldn't I automatically be able to :read it?


I just want to know if this is by design, o

CanCan uninitialized constant Ability::CanCan

Any idea what I could be doing wrong here? I know it's not very useful to say ability.can? :manage, all; however I'm just trying to get started with CanCan.


I do have the gem, and have run generate cancan:ability.


Thanks.


Error and Code:


uninitialized constant Ability::CanCan

CanCan - Access denied - Way to make CanCan Specify in the LOG Why?
Category : Programming Languages

I'm working to implement CanCan. For some reason CanCan keeps giving me Access Denied when I try to get specific about model permissions. And I can't figure out why.


Is there a way to get CanCan to be specific, perhaps in the logs or in development about Why Access is denied? something like, No Read Ability to XXX Model.


That would be helpful for debugging.

Rspec for cancan
Category : Programming Languages

I am not sure where I'll write test cases for our app, if i am using cacncan.


This should be in model or controller section.


In my case:


a user can delete or not a object.
To handle this case I used cancan and I think this code should be in model not in controller and how do I test this using rspec.


Please provide me a better advise.

Complex use of cancan
Category : Programming Languages

We're using cancan to authorize access to ~130 controllers, as things currently stand, this process takes ~100ms per authorization .. that is super slow (it literally takes around a second to just render the menu bar)


Is there techniques for breaking up cancan to simplify the work it needs to do per authorization, or in general speeding it up?


Does anyone have any cancan
