ruby on rails 4 - Factory Girl Passing nil to user model -

pretty simple, using factory girl following:

factorygirl.define     sequence :user_email |n|         "user#{n}@example.com"     end      # allows multiple user names     sequence :user_name |n|         "user#{n}"     end      factory :user, class: xaaron::user         first_name 'adam'         last_name 'something'         user_name {generate :user_name}         email {generate :user_email}         password 'somepasswordthat_is$ecure10!'     end end 

and there pass information user modal:

require 'bcrypt'  module xaaron   class user < activerecord::base     attr_accessor :password      before_save :encrypt_password      validates :first_name, presence: true     validates :user_name, uniqueness: true, presence: true, length: {minimum: 5}     validates_format_of :email, :with => /\a([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})\z/i     validates_uniqueness_of :user_name     validates_uniqueness_of :email     validates :password, presence: true, confirmation: true, length: { minimum: 10 }, if: :new_record?      def self.authenticate_user(user_name, password)         user = xaaron::user.find_by_user_name(user_name)         if(user && user.password == bcrypt::engine.hash_secret(password, user.salt))             user         else             nil         end     end      def encrypt_password         if password.present?             self.salt = bcrypt::engine.generate_salt             self.password = bcrypt::engine.hash_secret(password, salt)         end     end   end end 

from there, test tests user password validation or seeing if password generate same 1 store in database fails because factory girl passing nil database.

failed test output

  5) xaaron::user validation checks should validate user based on login credentials      failure/error: xaaron::user.authenticate_user(@user.user_name, @user.password).should == @user        expected: #<xaaron::user id: 5, first_name: "adam", last_name: "something", user_name: "user9", email: "user8@example.com", password: nil, salt: "$2a$10$y1m4yk.4znwvz2icp0ento", created_at: "2014-04-06 15:20:53", updated_at: "2014-04-06 15:20:53">             got: nil (using ==)      # ./spec/models/xaaron/user_spec.rb:33:in `block (3 levels) in <top (required)>' 

you can see in above that: password: nil shouldn't ...

the test generated fail

it "should validate user based on login credentials"   @user = factorygirl.create(:user)   xaaron::user.authenticate_user(@user.user_name, @user.password).should == @user end 

as requested - schema

activerecord::schema.define(version: 20140323000123)    # these extensions must enabled in order support database   enable_extension "plpgsql"    create_table "xaaron_users", force: true |t|     t.string   "first_name"     t.string   "last_name"     t.string   "user_name"     t.string   "email"     t.string   "password"     t.string   "salt"     t.datetime "created_at"     t.datetime "updated_at"   end  end 

remove attr_accessor :password class user. activerecord treat virtual attribute , not saved in database.

if notice rspec failure message received:

expected: #<xaaron::user id: 5, first_name: "adam", last_name: "something", user_name: "user9", email: "user8@example.com", password: nil, salt: "$2a$10$y1m4yk.4znwvz2icp0ento", created_at: "2014-04-06 15:20:53", updated_at: "2014-04-06 15:20:53"> 

password not saved in database. make sure remove attr_accessor user model password treated field , would saved in database.

next, need update example below:

it "should validate user based on login credentials"   @user = factorygirl.create(:user)   @login_user = factorygirl.build(:user)    xaaron::user.authenticate_user(@user.user_name, @login_user.password).should == @user  end 

@user contains actual record created in database, @user.password has encrypted password already. example fails because sending encrypted password authenticate_user method , re-encrypting encrypted password with:

bcrypt::engine.hash_secret(password, user.salt) 

in reality, example pass need pass actual password without encryption. why added @login_user in example.
