Question

When I create a new account through google, the email gets stored in my user record. When I create a user through twitter, the email column is blank. I’d like to update that entry if a user associates their current twitter account with google.

in my User model:

def self.create_from_hash!(hash)
  create! do |user|
    user.name = hash['user_info']['name']
    user.email = hash['user_info']['email']
  end
end

In sessions controller:

def create
  auth = request.env['rack.auth']
  unless @auth = Authorization.find_from_hash(auth)
    @auth = Authorization.create_from_hash(auth, current_user)
  end
  self.current_user = @auth.user
  flash[:notice] = "Welcome, #{current_user.name}."
  redirect_to '/'
end

and in the Authorization model:

def self.create_from_hash(hash, user = nil)
  user ||= User.create_from_hash!(hash)
  Authorization.create(:user => user, :uid => hash['uid'], :provider => hash['provider'])
end

How can I update that column when I am adding an authorization method?

Answer 1

I added the following line into my sessionscontroller create action, which seems to solve the issue:

if @user && (@user.email.blank? || @user.email.nil?)
    @user.update_attribute(:email, request.env['rack.auth']['user_info']['email']) unless request.env['rack.auth']['user_info']['email'].nil? || @user.nil?
end
