Question

For some reason @store object with three attributes won’t assign the third value(generated token string).The model has user_id, product_id and token_string.But when it comes to token_generate function nothing is assigned,and end up with nil in the token_string column in the database .Product_id and user_id are saved perfectly in the database though.What is going on here?Thank you in advance.

class Store < ActiveRecord::Base
  require 'digest/sha1'

  attr_accessor :token_string

  before_save :token_generate

  def save_with_payment 
     #Until here the object has user_id and product_id attribute values
     save!
  end

  private

  def token_generate
    self.token_string = Digest::SHA1.hexdigest("random string")
  end
end

controller

def create
  @store=Store.new(params[:store])

  if @store.save_with_payment
    redirect_to :controller=>"products",:action=>"index"
  else
    redirect_to :action=>"new"
  end
end

@SrdjanPejic is correct, try removing the attr_accessor :token_string line which is likely blocking setting the :attributes hash value needed for the INSERT statement.
