I have the following error when submitting my registration information:

   NoMethodError in Devise::RegistrationsController#create

undefined method `downcase!' for 0:Fixnum

\livu_pamatskola\app\views\devise\registrations\new.html.erb:

`Reģistrācija`


 resource_name, :url => registration_path(resource_name)) do |f| %>
  


    
    
    
    
    
    
    
     true %>
    
    
    
    
    
    

     "button-link" %>

I understand that the problem is in Registrations Controller, as I think, but I don't have a such controller. I have searched all over the internet for solutions, but I haven't find anything, just spent a lot of time, so I need your help.

Problem solved:

When I was creating my user model for Devise, I included email attribute in migration. Problem was there when adding devise to user model, it adds email fields by default too, so it was conflicting with my previous migration.

I am glad that I have solved it, because I don’t have a time for these bugs. Thank you all for helping.

It looks like your user model has wrong type of attributes. Make sure your database contains valid type of fields. Learn more here: https://github.com/plataformatec/devise

Your problem might be related to known case-insensitive keys issue. Add folowing snippet to your config/initializers/devise.rb file: http://anti-pattern.com/case-insensitive-keys-with-devise

Registration controller is defined in Devise library and it is automatically added to your application controllers if you add devise to the Gemfile.
Are you submitting numerical information for some of the fields? Like, “123” for the username? That could be an issue with Devise if it is getting a number as a string, but thinking it’s actually a number.
