CanCan integration for ActiveAdmin

ActiveAdmin-Cancan¶ ↑

ActiveAdmin-Cancan provides a smooth integration of the two gems ActiveAdmin and Cancan.

<img src=“https://secure.travis-ci.org/11factory/activeadmin-cancan.png” />

Getting Started¶ ↑

Active Admin - Cancan is released as a Ruby Gem. The gem is to be installed within a Ruby on Rails 3 application. To install, simply add the following to your Gemfile:

gem 'activeadmin-cancan'

Configure CanCan¶ ↑

You just have two things todo

1. Create the CanCan ability class¶ ↑

User permissions are defined in an Ability class. CanCan includes a Rails 3 generator for creating this class.

rails g cancan:ability

See CanCan page [github.com/ryanb/cancan/wiki/defining-abilities] for details.

2. Handle Unauthorized Access¶ ↑

If the user authorization fails, a CanCan::AccessDenied exception will be raised. You can catch this and modify its behavior in the ApplicationController.

class ApplicationController < ActionController::Base
  rescue_from CanCan::AccessDenied do |exception|
    redirect_to root_url, :alert => exception.message
  end

  def current_ability
    @current_ability ||= Ability.new(current_admin_user)
  end 
end

See CanCan page [github.com/ryanb/cancan/wiki/exception-handling] for more information.

How it works¶ ↑

I have just made the integration between the two gems, the two steps above are the only ones todo to get roles working with ActiveAdmin.

activeadmin-cancan's Issues

Cancancan has replaced Cancan

Cancan is no longer being updated. Cancancan https://github.com/CanCanCommunity/cancancan has been created as a continuation of Cancan. Is this compatible?

Models not loaded in normal controllers

When I require your gem, FooController#index doesn't load @foos etc. Is this by design or is this a bug? How do you recommend I handle this?

how to assign permissions to the user and how to create the form as a new user with the option of permissions?

how to assign permissions to the user and how to create the form as a new user with the option of permissions?

immediately after bundle install

/gems/activeadmin-cancan-0.1.2/lib/activeadmin-cancan/authorization.rb:9:in register': undefined local variable or methodresource_dsl' for #ActiveAdmin::Namespace:0x007f8d41431888 (NameError)

Authorization Not Performed

I`ve installed the activeadmin gem and also this one and I'm getting this error:

CanCan::AuthorizationNotPerformed in Admin::DashboardController#index

This action failed the check_authorization because it does not authorize_resource. Add skip_authorization_check to bypass this check.

this gem not compatible to activeadmin 0.5.0

i'm install this gem in activeadmin 0.5.0 not working the error :

undefined local variable or method `resource_dsl' for #ActiveAdmin::Namespace:0xa2374b8

help pls

Deeper integration of CanCan into ActiveAdmin

See my gist: https://gist.github.com/3040303

It enforces cancan on menus, action items, default_actions in index tables, and when using AA's auto_link.

Not sure if it is working

Hi,

So far I have no errors on the logs...

The thing is that I have some abilities that allow a user with role 'leader' only read projects with an status of finished... But still the projects index page is listing all the projects, and if I click on the show page of a started project that leader user is still able of seeing the information.

Is this the correct behavior?

if i install the activeadmin gem from the current github repo, then i get that errormessage

NoMethodError - protected method `authorize!' called for #Admin::UsersController:0xa4f301c:
