Rails 4, Devise - Error messages on Login aren't working properply

Question

Piece of code on github: http://bit.ly/ZMSJXQ

1) On Login, I get no error messages if:

• email doesn't exist in db
• password is empty
• password is wrong

devise_error_messages! is empty as resource.errors is empty. Looks like resource doesn't get validated. Why?

---

2) If I run resource.valid? then resource.errors returns :email=>["has already been taken"], :password=>["can't be blank"]

I get error messages but they're not correct. 'Email has already been taken' doesn't make sense on log in. Why?

(Sign up, Reset password etc. work fine.)

devise_error_messages! is only a helper to return a formatted list of resource.errors. Some devise failure messages are set in rails's flash object though. Somewhere in your layout you should render those flash messages:

<%- flash.each do |name, msg| -%>
  <%= content_tag :div, msg, id: "flash_#{name}" %>
<%- end -%>
