Question

I am using Devise gem for authentication in my current project. I am stuck with an issue to use devise registration and login form inside my custom form and I am not sure how to implementation it in my project.

This custom form has 20-25 fields and if current user is not logged in, I want to include device login and registration forms as well on same view. So when user hit save button of the form, controller will first authenticate or register the user and then later save the form.

class BookController < ApplicationController
    def new
        @book = Shop::Book.new
    end

    def create
        @book = Book.new(params[:book])

        # TODO::
        # validate / register the user if not currently logged-in

        if @book.save
            redirect_to :action => 'list'
        else
            @subjects = Subject.find(:all)
            render :action => 'new'
        end   
    end
end

check out Digi_Cazter’s link then add the form after checking for signed_in?

In your create method something like this should work:

   @user = User.new(:email => '[e-mail]', :password => 'password',    #values from params   
   :password_confirmation => 'password')
   @user.save
   sign_in @user  #if you want to do this

       if @book.save
            redirect_to :action => 'list'
        else
            @subjects = Subject.find(:all)
            render :action => 'new'
        end
