Devise create various forms, among them one for signing up and one for logging in of course. These are the forms as they are generated in Devise 1.0.8:
<h2>Sign up</h2>
<%= form_for(resource, as: resource_name, url: registration_path(resource_name)) do |f| %>
<%= f.error_messages %>
<div>
<%= f.label :email %><br>
<%= f.text_field :email %>
</div>
<div>
<%= f.label :password %><br>
<%= f.password_field :password %>
</div>
<div>
<%= f.label :password_confirmation %><br>
<%= f.password_field :password_confirmation %>
</div>
<div>
<%= f.submit "Sign up" %>
</div>
<% end %>
<%= render partial: "shared/devise_links" %>and
<h2>Sign in</h2>
<%= form_for(resource, as: resource_name, url: session_path(resource_name)) do |f| %>
<div>
<%= f.label :email %><br>
<%= f.text_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 %>
<%= render partial: "shared/devise_links" %>If you try to put them somewhere else you’ll run into some problem. There are some variables/methods those forms use that you’ll be lacking, specifically: resource_name, resource and for logging in also devise_mapping. I’ve recently tried to put them both in the homepage for an upcoming project of mine and this is how I’ve solved it:
module ContentHelper
def resource_name
:user
end
def resource
@resource ||= User.new
end
def devise_mapping
@devise_mapping ||= Devise.mappings[:user]
end
end
