在索引页面devise中调用render sign_in

Question

I'm trying to call a render of sign_in in my index page.

I don't want to go to another page I want to stay in the same page.

I have tried:

<%= render :partial ... %>

<%= render :file %>

I get an error.

Do you have any idea to how I can do that?

my file in devise/sessions/_new.html.erb

 <h2>Sign in</h2>

<%= form_for(resource, :as => resource_name, :url => session_path(resource_name)) do |f| %>
  <div><%= f.label :email %><br />
  <%= f.email_field :email %></div>

  <div><%= f.label :password %><br />
  <%= f.password_field :password %></div>

  <% if devise_mapping.rememberable? -%>
    <div><%= f.check_box :remember_me %> <%= f.label :remember_me %></div>
  <% end -%>

  <div><%= f.submit "Sign in" %></div>
 <% end %>
<% end %>

if i put content_for on the file i get an error do you know how i can render the file in my index after clicking on the link .

Answer 1

What error do you get?

If you want to render a partial view inside another view, save it with a _ prefix. So call your file:

_sign_in.html.erb

To render a partial as part of a view use the render method within the view:

<%= render "sign_in" %>

If it is not in the same folder as the other views of that controller, ie called 'shared' :

<%= render "shared/sign_in" %>
