cancan

I'm looking to do pagination with cancan however it's not obvious how to integrate this with gems such as will_paginate. Ideally cancan's load_resource will delegate to will_paginate and add extra conditions. For example in cancan I've declared guest users can :read, Post, :published => true and this is handled automatically by load_resource. However I'd then like to have will_paginate page through all these results. Any ideas. Regards Brad This is simple to do with kaminari https://github.com/amatsuda/kaminari in my PostsController I just do before_filter :load_by_pagination, :only => :index

I'm currently stuck on how to separate roles for CanCan depending on each condition that we want. In our application, there are many categories (such as math, english, history, etc.) and within each are many courses. Each user can have many different roles on each category. For example, John can be a "reader" for math, which means he can read all the courses that are in math. John can also be a "writer" for english, which means he can read all the courses in english, create a course within category english, and edit/delete only the courses he created within english. If these were the only

How do I grant permission to edit/ destroy links on a by-user basis in the user index of rails? I'm using Rails3, Devise and CanCan to define role based abilities. I'd like the current user to be able to see and access a link to edit/delete their profile in the user index page. They should not be able to see or access these links for all other users. I've set up the following in the index view: <% if can? :update, @user %> <%= link_to 'Edit', edit_user_registration_path(@user) %> | <% end %> And in abilities.rb def initialize(user) can :update, User, :id => user.id if user.role? :super_admin

I am very new to ruby and I have been really struggling with this for months. I searched extensively and tried what the answers said but still no luck. (I tried Multiple user models with Ruby On Rails and devise to have separate registration routes but one common login route but didnt work) I currently have a user.rb model and it is connected to devise and works fine. 1- On the sign-up page, I would like to have 3 buttons that would lead to separate registration forms (one each for business, manager and the already existing user). Do I set this up in routes.rb? 2- The forms will have different

I'm using rails 4.0.2, devise and cancancan . I'm trying to allow an admin to create new users. Admin users are assigned with a boolean field in the users table. In ability.rb I have the following: can :manage, :all if user.admin? Following some of the advise in this question I created a new controller called AdminsController and it looks like so: class AdminsController < Devise::RegistrationsController def create build_resource(sign_up_params) if resource.save redirect_to admin_editors_path else clean_up_passwords resource respond_with resource end end def new build_resource({}) end end I've

Here is the Controller I want to test: class UsersController < ApplicationController load_and_authorize_resource def index @users = User.all respond_to do |format| format.html # index.html.erb format.json { render json: @users } end end def show @user = User.find(params[:id]) respond_to do |format| format.html # show.html.erb format.json { render json: @user } end end #other actions here end As you can see I use CanCan method load_and_authorize_resource so I've written a ControllerHelper for RSpec: # spec/support/controller_spec.rb module ControllerHelper def should_authorize(action, subject)
