Ruby on Rails / gem devise / login page in a modal












-1















I would like to have the login page in a modal (instead of opening a separate page). I am using the gem devise to create account.
In views/layouts/application.html.erb, I created the code to call for the modal:



<div id="openModal" class="modalDialog">
<div>
<a href="#close" title="Close" class="close">X</a>
<%=render 'devise/sessions/newsession'%>
</div>
</div>


Then in views/devise/sessions/_newsession.html.erb



<%= form_for(resource, as: resource_name, url: session_path(resource_name)) do |f| %>

<div class="field">
<%= f.label :email %><br />
<%= f.email_field :email, autofocus: true %>
</div>

<div class="field">
<%= f.label :password %><br />
<%= f.password_field :password, autocomplete: "off" %>
</div>

<div class="actions">
<%= f.submit "Log in" %>
</div>
<% end %>

<%= render "devise/shared/links" %>


I am getting the following error message:




undefined local variable or method `resource' for <#:0x007fafd8bc60f8>




It looks like devise is not recognized in the page application.html.erb.



Would you understand where the error come from?

          As you're rendering the login form which uses a resource and resource_name variables which aren't initialized from "outside" a devise controller, what you can do is to add them to your ApplicationHelper file to be able to work with them from your current controller or any other.



          Try editing your helper file adding the resource, resource_name and devise_mapping:



          module ApplicationHelper
          def resource_name
          :user
          end

          def resource
          @resource ||= User.new
          end

          def devise_mapping
          @devise_mapping ||= Devise.mappings[:user]
          end
          end


          Just to add that if you want to render the sessions#new view file you can simply render this file as render file: 'devise/sessions/new', if you've run the devise:views command, this would help you to maintain just one form instead creating a new one, of course, is just a suggestion.

            1+ for Sebastians answer. Another way is pass the values to RenderingHelper:



            <%= render 'layouts/modal/myModal', resource: User.new, resource_name: :user, devise_mapping: Devise.mappings[:user] %>

              Used this in the past, worked great:



               <div class="modal custom fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
              <div class="modal-dialog" role="document">
              <div class="modal-content">
              <div class="modal-header">
              <button type="button" class="close" data-dismiss="modal" aria-hidden="true">
              &times;
              </button>
              <h2 class="text-center">Connexion</h2>
              </div>
              <div class="modal-body">
              <%= form_for(:user, :url => session_path(:user)) do |f| %>
              <div class="email-container">
              <%= f.text_field :email, :class =>"form-control",placeholder: "Email", value:"" %>

              <div class="password-container">

              </div>
              <%= f.submit 'Login', :class =>"form-control" %>
              <%= f.check_box :remember_me, label: "Remember me", value: "true" %>
