cancan

问题 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 回答1: This is simple to do with kaminari https:/

问题 Trying to set up Cancan within an app of mine and having trouble with my PostsController . In a nutshell, when a Post is created I'd like it associated with the current_user so my create action looks something like this: class PostsController < ApplicationController before_filter :login_required, :except => [:index, :show] load_and_authorize_resource ... def create # @post = Post.new(params[:post]) # <-- covered by load_and_authorize_resource @user = current_user @post = @user.posts.create

问题 I'm using devise and cancan in a Rails 3.2 project. I have an event model with a boolean flag public . If the event is marked as public => true then I want anybody, signed in or not to be able to access the record with GET /events/:id If it is marked as public => false then a series of cancan abilities will decide authorization and access to the above resource. What is the best pattern for achieving this? 回答1: You can do that by skip the authenticate_user! in case of you have this args skip

问题 I have a requests spec for interactions with the User model. I want to make sure that Users with the Admin role can create/edit/destroy Users. I'm having a problem right now where the Edit action does not update the user. Everything works properly when I manually go through the actions on the site itself, but the tests fail to update the user. Here's my spec: it 'edits a user' do @user = FactoryGirl.create(:user) visit new_user_session_path unless current_path == new_user_session_path fill_in
