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.<\/code><\/p>\n

Problem solved:<\/strong><\/p>\n
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.<\/p>\n
I am glad that I have solved it, because I don’t have a time for these bugs. Thank you all for helping.<\/p>\n

  1. \n
    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<\/p>\n
    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<\/p>\n
    Registration controller is defined in Devise library and it is automatically added to your application controllers if you add devise to the Gemfile.<\/p>\n<\/li>\n
  2. \n
    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.<\/p>\n<\/li>\n<\/ol>\n
