Email can't be blank. How to create a user with blank email?

[ksbek]

I can't create the user if the email is nil or blank even the email field is not a required field in the database. Bit if I remove include DeviseTokenAuth::Concerns::User from the user model I can create with a blank email.

A few validations are added by default here There is a default_callbacks options you can disable to prevent the inclusion of DeviseTokenAuth::Concerns::UserOmniauthCallbacks concern Just make sure you know what you're doing, you will not only lose validations but everything inside that concern You can find the config option in here In your devise_toke_auth.rb file:

DeviseTokenAuth.setup do |config|
  ...
  # By default we will use callbacks for single omniauth.
  # It depends on fields like email, provider and uid.
  config.default_callbacks = false
end
