ruby on rails - Redirect to Page after Facebook Sign Up -

i'm trying redirect user after successful facebook sign (not sign in).

i want redirect /getstarted/welcome after user registers for first time.

my omniauth callback :

def facebook         # need implement method below in model (e.g. app/models/user.rb)         @user ||=             user.find_for_facebook_oauth(request.env["omniauth.auth"], current_user)          if @user.persisted?             # throw if @user not activated             sign_in_and_redirect @user, event: :authentication             if is_navigational_format?                 set_flash_message(:notice, :success, kind: "facebook")             end         else             session["devise.facebook_data"] = request.env["omniauth.auth"]             redirect_to new_user_registration_url         end     end 

for devise use

def after_sign_up_path_for(source)   '/getstarted/welcome' end 

my user model:

facebook settings

  def self.find_for_facebook_oauth(auth, signed_in_resource = nil)     user = user.where(provider: auth.provider, uid: auth.uid).first     if user.present?         user     else         user = user.create(first_name:auth.extra.raw_info.first_name,                                              last_name:auth.extra.raw_info.last_name,                                              facebook_link:auth.extra.raw_info.link,                                              user_name:auth.extra.raw_info.name,                                              provider:auth.provider,                                              uid:auth.uid,                                              email:auth.info.email,                                              password:devise.friendly_token[0,20])     end end 

can me set ?

i solved adding user model

attr_accessor `just_signed_up` 

and setting in user.find_for_facebook_oauth in part of block create new user (first_or_create block).

edit: more explanation

so in ruby (not rails) there class method/macro called attr_accessor (actually theres attr_reader , attr_writer, attr_accessor shorthand calling other two)

if you, in user model write

class user   attr_accessor :some_attribute 

then you're able perform

u = user.first u.some_attribute = 'asdf' u.some_attribute # => 'asdf' 

but attribute not going saved db, may used temporary storage of value in rails model.

another thing know there 2 "values" false in ruby, false , nil.

using 2 tricks may create new user , temporarily set flag on object

u = user.create u.just_signed_up = true u.just_signed_up # => true u.reload! # fetches record db u.just_signed_up # => nil

and since nil false, check fail every user except ones created!
