How To: Display a custom sign_in form anywhere in your app

It’s easy to create a custom login form that can be used anywhere in your application.

Here’s an example in HAML:

= form_tag new_user_session_path do
  = text_field_tag 'user[email]'
  = password_field_tag 'user[password]'
  = check_box_tag 'user[remember_me]'
  = label_tag 'user[remember_me]', 'Remember me'
  %button Login
  = link_to "Forgot your password?", new_password_path('user')

Another example with form_for and posting to user_session_path:

<%= form_for("user", :url => user_session_path) do |f| %>
  <%= f.text_field :email %>
  <%= f.password_field :password %>
  <%= f.check_box :remember_me %>
  <%= f.label :remember_me %>
  <%= f.submit 'Sign in' %>
  <%= link_to "Forgot your password?", new_password_path('user') %>
<% end %>

Note: “user” in this context is the resource you specified when setting up Devise.
