Override method of UsersController in Clearance - ruby-on-rails

I want to change the
def url_after_create
'/'
end
of UsersController in Clearance. If I do this:
class UsersController < Clearance::UsersController
protected
def url_after_create
'/dashboard'
end
end
When I'm trying to sign up a new user, which works perfectly when not overriding, I get the following: The action 'index' could not be found for UsersController -- The action (post) is to '/users' and it seems that since the index action is not defined it fails. What should I do?
EDIT: Added code of Clearance::UsersController
class Clearance::UsersController < ApplicationController
unloadable
skip_before_filter :authorize, :only => [:new, :create]
before_filter :redirect_to_root, :only => [:new, :create], :if => :signed_in?
def new
#user = ::User.new(params[:user])
render :template => 'users/new'
end
def create
#user = ::User.new(params[:user])
if #user.save
sign_in(#user)
redirect_back_or(url_after_create)
else
flash_failure_after_create
render :template => 'users/new'
end
end
private
def flash_failure_after_create
flash.now[:notice] = translate(:bad_email_or_password,
:scope => [:clearance, :controllers, :passwords],
:default => "Must be a valid email address. Password can't be blank.")
end
def url_after_create
'/'
end
end

This line match ':controller(/:action(/:id(.:format)))' located in routes was causing the trouble. Commenting that solved it.

ruby - run http://localhost:3000/admin/users but redirect_to http://localhost:3000/admin/login

I am new in Ruby on Rails.

end

Thank you!
Your UsersControllers is under the admin namespace, that's to say you must be logged in order to access to this.
If you want to have access without validating the user is currently logged in, then you'll have to remove the constraint or verification to the controller or to make a new controller and index method which point to /admin/users but this time without the user verification.
That's:
# app/controllers/users_controller.rb
class UsersController < ApplicationController
...
def index
#users = User.all
end
...
end
# config/routes.rb
get '/users', to: 'users#index'
'/users' or '/admin/users' as you want to do it, but if you use the last one then any person must infer that's a restricted resource .

how to define the admin_user to delete posts? Ruby on rails app

I am trying to get admins to be able to delete postings by users.
This is the code I'm using inside post.html.erb
<% if current_user.admin? %>
<%= link_to "delete", post, method: :delete %>
<% end %>
This is what I have inside the controller
class PostsController < ApplicationController
before_filter :signed_in_user
before_filter :admin_user, only: :destroy
before_filter :correct_user, only: :destroy
def destroy
#post.destroy
redirect_to root_path
end
private
def correct_user
#post = current_user.posts.find_by_id(params[:id])
redirect_to root_path if #post.nil?
end
I'm able to get it working for correct_user, but not for admin. I get this error message
undefined local variable or method `admin_user' for #<PostsController:0x5fda230>
I tried to def admin_user as user.id ==1
private
def admin_user?
current_user && current_user.id == 1
end
But I'm experiencing the same error message.
before_filter :admin_user, only: :destroy
class ApplicationController
def admin_user?
if current_user && current_user.id == 1
return true
else
redirect_to root_url, :error => "Admin only"
return false
end
end
end
Since admin_user? is called from any controller so put it in application controller
class ApplicationController < ActionController::Base
def admin_user?
unless current_user && current_user.admin?
redirect_to root_url
return false
end
end
end
class PostsController < ApplicationController
before_filter :signed_in_user
# before_filter :admin_user?, only: :destroy
before_filter :load_post, :only: :destroy
def destroy
#post.destroy
redirect_to root_url
end
private
def load_post
#post = current_user.admin? ? Post.find(params[:id]) : current_user.posts.find(params[:id])
end
end
UPD:
As I understood from comments you want users to be able to destroy their own posts and admin to be able to destroy any posts. In this case you don't have to check is user admin in before_filter, e.g. remove this line:
before_filter :admin_user?, only: :destroy

Rails cancan issue with before_filter

I recently integrated cancan (1.6.9) into my Rails (3.2.10) project for authorization, and I'm having an issue with manually loading a resource in a before_filter. Here's a brief description of my scenario.
In config/routes.rb, I have the following entries...
resources :users
match '/profile', :to => 'users#show'
Here's what my users_controller.rb looks like...
class UsersController < ApplicationController
before_filter :load_show_resource, :only => :show
load_and_authorize_resource
...
def show
end
...
private
def load_show_resource
#user = params[:id] ? User.find(params[:id]) : current_user
end
end
If my current_user's id is 1, this code will let me access localhost:3000/users/1 but not localhost:3000/profile.
The entry in my cancan ability.rb class that's blocking this access is seen below - it's the cannot section. If I comment out the cannot entry, both urls work.
...
can [:show, :update], User, :id => user.id
cannot [:show, :update, :destroy], User do |u|
u.site_id != user.site_id
end
....
Shouldn't cancan use the resource that's being manually loaded in the before_filter for the show action regardless of whether or not params[:id] is present?
Interestingly enough, if I modify my users controller (see below) to use skip_load_and_authorize_resource :only => :show and manually calling authorize! in the show action, both urls work. Also, if I remove cancan altogether both urls work.
class UsersController < ApplicationController
load_and_authorize_resource
skip_load_and_authorize_resource :only => :show
...
def show
#user = params[:id] ? User.find(params[:id]) : current_user
authorize! :show, #user
end
...
private
def load_show_resource
#user = params[:id] ? User.find(params[:id]) : current_user
end
end
So, my question is why does what's explained in the Override loading in the cancan documentation, not work in this situation?
Thanks!
# controller
class UsersController < ApplicationController
load_and_authorize_resource, :except => :show
# skip_load_and_authorize_resource :only => :show
...
def show
#user = params[:id] ? User.find(params[:id]) : current_user
authorize! :show, #user
end
...
end
# ability.rb
can [:show, :update, :destroy], User do |u|
u.id == user.id && u.site_id == user.site_id
end

handling exception in nested resources with Mongoid::Errors::DocumentNotFound rails 3.1

I have in my application_controller.rb
class ApplicationController < ActionController::Base
protect_from_forgery
rescue_from Mongoid::Errors::DocumentNotFound, :with => :render_not_found
def render_not_found
render :file => "#{Rails.root}/public/404.html", :status => 404, :layout => false
end
end
Then I call
This code working fine for example in my routes.rb:
resources :posts
The problem is that If I have a nested resource like this in routes.rb:
resources :users do
resources :posts
end
I have this in posts_controller.rb
class PostsController < ApplicationController
end
Now with this parent :users does not work!. I have that write in every actions from posts_controller.rb this nested resource the next for working fine e.g..
def show
#post = Post.find(params[:id])
respond_to do |format|
format.html # show.html.erb
format.json { render json: #post }
end
rescue
render_not_found
end
In your controller code here,
class Users::PostsController < ApplicationController
end
you have Users::Posts, but you are not specifying the location of the PostsController in the routes above.

Multi-form in rails using Wicked Gem and Devise

I am trying to set a multi-form login system using the Wicked gem. I have devise installed up and running correctly, when following these steps:http://railscasts.com/episodes/346-wizard-forms-with-wicked.
I'm not being redirected to the user_step_paths? everything is done as stated in the tutorial but, I'm guessing because I'm using devise i need to do it in a controller inherited by devise? my code is below for the controllers:
users_controller.rb
class UsersController < Devise::RegistrationsController
def new
#user = User.new
end
def create
#user = User.new(params[:sign_up])
if #user.save
session[:user_id] = #user.id
redirect_to user_steps_path
else
redirect_to new_user_registration_path
end
end
end
users_steps_controller.rb
class UserStepsController < ApplicationController
include Wicked::Wizard
steps :education, :social
def show
render_wizard
end
end
routes
get 'pages/home'
devise_for :users, :controllers => { :registrations => 'users'}
resources :user
resources :user_steps
1.Needed a update method in the controller and needed to define user in the show method:
def show
#user = current_user
render_wizard
end
def update
#user = current_user
#user.update_attributes(user_params)
render_wizard #user
end
2.Needed to generate the devise controllers:
rails generate devise:controllers [scope]
3.Update the registration_controller for devise
class Users::RegistrationsController < Devise::RegistrationsController
# before_filter :configure_sign_up_params, only: [:create]
# before_filter :configure_account_update_params, only: [:update]
# GET /resource/sign_up
def new
super
end
# POST /resource
def create
super
end
# GET /resource/edit
# def edit
# super
# end
# PUT /resource
def update
super
end
# The path used after sign up.
def after_sign_up_path_for(resource)
user_steps_path
end
# The path used after sign up for inactive accounts.
def after_inactive_sign_up_path_for(resource)
super(resource)
end
end
4.This controller is invalid, you need to use the generated controllers by devise:
class UsersController < Devise::RegistrationsController
