Devise: How to create a new user being already logged in? - ruby-on-rails

Question

I'm going to create a multi user app, so, I will have a admin user that will have permission to create new ones.
I've created the UsersControllerbut when trying to create a new user, being already signed in, I'm getting redirect to root_path with an error message that says "You are already signed in".
So, what should I do to make this possible?

Answer 1

Found.
I have just to removed the registerable module from devise and it works.

Answer 2

In a controller method can't you just go:
def create_user
#user = User.new(:email => params[:email], :password => params[:password])
#user.save
...
end

Answer 3

This is how I am doing it in 2015
# in your terminal
rails g controller Registrations
Registrations controller should look like this,
# registrations_controller.rb
class RegistrationsController < Devise::RegistrationsController
skip_before_filter :require_no_authentication, only: [:new]
def new
super
end
end
The important line is the skip_before_filter...
That will disable the requirement that there be no user logged in.
The routes for the controller looks like this,
# routes.rb
devise_for :users,
controllers: {:registrations => "registrations"}
That will tell devise to use your custom registrations controller
Finally, setting up a custom route to that action:
# routes.rb
as :user do
get "/register", to: "registrations#new", as: "register"
end

Answer 4

There is another solution.
You must override registration controller and remove action (or actions) from prepend_before_filter.
DeviseRegistrationController source is here.
You can see:
prepend_before_filter :require_no_authentication, only: [:new, :create, :cancel]
It jumps into require_no_authentication before create method. If you want create new user while you are logged in, just remove :create from array.

Answer 5

I added in the Registrations Controller:
class RegistrationsController < Devise::RegistrationsController
...
skip_before_action :require_no_authentication, only: [:new, :create]
...
end
And it worked for me. I can now go and create a new user.

Answer 6

You could either override the default devise controller and add in your custom logic, or, It would probably be easier however to make a new (Admin) controller and simply create a user using one of it's actions.
#user = User.create!(:name => params[:foo], :email => params[:bar])
redirect_to #user
Devise has loads of guides on how to customise it's behaviour here: https://github.com/plataformatec/devise/wiki/_pages
This one in particular may be of interest to you: https://github.com/plataformatec/devise/wiki/How-To:-Manage-Users-with-an-Admin-Role-(CanCan-method) But make sure to have a look over the rest of the articles, there's a lot of them.

Answer 7

in case someone still looking for help, because it tooks a while for this to work , no clear answers
in your controller
class UsersController < ApplicationController
def new
#user = User.new
end
def add_user
#user = User.new(user_params)
if #user.save!
redirect_to root_path
end
end
private
def user_params
params.require(:user).permit(:email, :password, :password_confirmation)
end
end
in your routes :
get 'employees', to: 'users#new'
post 'employees', to: 'users#add_user'
and finally a form like this:
<%= form_for User.new , :url => {:action => "add_user"} do |user| %>
<%=user.email_field :email%>
<%=user.password_field :password%>
<%=user.password_field :password_confirmation%>
<%=user.submit 'add'%>
<%end%>

#Mourkeer +1
For simple_form 4.2.0 take #Mourkeer code and replace route.rb by:
# route.rb
devise_for :users, path_names: { registration: "registrations" }
