Devise restrict sign up to Admin
I am working on a Rails App that uses Devise as t开发者_Go百科he authentication module, however I want to customize it so that CanCan will only permit Administrators to create a new user. I am having a hard time understanding how to customize the controller for Devise so that this can be done. Any help would be appreciated.
You don't need to customize anything :D
Remove :registerable from your Devise model.
Create your Users CRUD* (just scaffold users)
Use CanCan for user permission on your Users Controller.
*Check Devise's wiki on how to create a Users CRUD, there is a routing trick you need to do
You can create a "User" controller that will manage users and then simply set permissions for it. So in your new User controller you can have something like:
class UserController < ApplicationController
load_and_authorize_resource
def index
end
def new
end
def show
end
def create
if @user.save
flash[:notice] = "Successfully created User."
redirect_to root_path
else
render :action => 'new'
end
end
def edit
end
def update
params[:user].delete(:password) if params[:user][:password].blank?
params[:user].delete(:password_confirmation) if params[:user][:password].blank? and params[:user][:password_confirmation].blank?
if @user.update_attributes(params[:user])
flash[:notice] = "Successfully updated User."
redirect_to user_index_path
else
render :action => 'edit'
end
end
def destroy
if @user.destroy
flash[:notice] = "Successfully deleted User."
redirect_to user_index_path
end
end
end
Assuming you have administrators set to:
can :manage, :all
You should be good to go.
In your routes file you'll need to set up your routes:
resources :user, :controller => "user"
Hope this helps!
