    <% @page_title = 'Staff Area Login' -%>

    <%= form_for(:stuff, :url => {:action => 'send_login'}) do -%>

    <p>Username:  <%= text_field_tag('username', params[:username]) %></p>

    <p>Password: <%= password_field_tag('password') %></p>

    <%= submit_tag("Log in") %>

    <% end -%>
Solution

  • You can use the :html hash. 

    <%= text_field_tag('username', params[:username], :html => {:id => "username_field"}) %>
