How to fix undefined method `remote_avatar_url='?

Question

Ruby on Rails

I'm trying to connect authorization through omniauth-twitter
Gives an error

undefined method `remote_avatar_url=' for #<User:0x0000000012a69c00> Did you mean? remove_instance_variable

def self.find_or_create_from_twitter_omniauth(auth)
  user = where(provider: auth.provider, uid: auth.uid).first_or_create
  unless auth.info.image.nil?
    user.remote_avatar_url = auth.info.image.gsub('http://', 'https://').gsub('_normal', '')
  end
  user.update(
    username: auth.info.name,
    password: Devise.friendly_token[0, 20],
    email: "#{SecureRandom.hex}#{auth.info.nickname}"
  )
  user
end

omniauth-twitter obviously has nothing to do with it. Apparently, you copied somewhere an example from remote_avatar_url. But they did not migrate with the corresponding column in the database, which should store the string with the url.
