I found this link very interesting:
https://github.com/plataformatec/devise/wiki/How-To:-Allow-users-to-sign-in-using-their-username-or-email-address
I don't know the dynamics of Devise, but I looked at your application:
2 controllers: application and home. home has show, new, edit defs. All
empty
1 model user
3 view folders: devise, home, layouts.
Devise has folder session with new.html.erb. It has:
<%= form_for(resource, :as => resource_name, :url =>
session_path(resource_name)) do |f| %>
<div class="field"> <%= f.label "Username or Email" %><br /> <%=
f.text_field :signin, autofocus: true %> </div> Where have you defined
resource?
