如何使用omniauth和devise保存Facebook名称

Question

I'm trying to save the name of a Facebook user upon saving that user, but I don't seem to be able to. I have followed the guides on the devise github and the integration with Facebook works fine; the users email is saved as is to be expected. However, I can't figure out how to save the users name. Right now, I do this:

  def self.find_for_facebook_oauth(access_token, signed_in_resource=nil)
    data = access_token['extra']['user_hash']
    if user = User.find_by_email(data["email"])
      user
    else # Create a user with a stub password.
      User.create(:email => data["email"], :name => data["name"], :password => Devise.friendly_token[0,20]) 
    end
  end

but that doesn't work. Am I doing something wrong?

Answer 1

Seems like Auth hash schema has changed a lot: https://github.com/intridea/omniauth/wiki/Auth-Hash-Schema

def self.find_for_facebook_oauth(access_token, signed_in_resource=nil)
  data = access_token.extra.raw_info
  if user = User.where(:email => data.email).first
    user
  else
    # Create a user with a stub password. 
    user = User.create!(:username => data.username ? data.username : data.nickname , :email => data.email, :password => Devise.friendly_token[0,20])
  end
end

The users name is stored in:

auth = request.env['omniauth.auth']  #I think this is what your access_token variable equates to.
auth['user_info']['name']

If that is not what you need, I suggest you inspect the contents of the access_token.
