Rails3 + Rspec2 + Factorygirl关联

Question

我有以下模型

class User < ActiveRecord::Base
  devise :database_authenticatable, :registerable,
        :recoverable, :rememberable, :trackable, :validatable
   
     attr_accessible :email, :password, :password_confirmation, :remember_me, :company_id
end


 class Company < ActiveRecord::Base
   attr_accessible :email, :name
 end


#test/factories/companies.rb
FactoryGirl.define do
  factory :company do
    name "sample company"
    email "sample@company.com"
  end
end

#test/factories/users.rb
FactoryGirl.define do
 factory :user do |u|
   u.email 'sameera@sample.com'
   u.password 'welcome'
   u.password_confirmation 'welcome'
   u.association :company, :factory => :company
 end
end


#spec/models/user_spec.rb
require 'spec_helper'
 
describe User do
   describe "Validations" do
     it "should validate the email" do
       user = FactoryGirl.build(:user, :email => nil)
       user.should have(1).error_on(:email)
     end
   end
end

但是我得到了这个错误，有了guard (即使在重新启动Guard之后)

Done.

您的User模型并没有像您的工厂假设的那样声明belongs_to关联：

您应该添加它：

class User < ActiveRecord::Base
  devise :database_authenticatable, :registerable,
        :recoverable, :rememberable, :trackable, :validatable

     attr_accessible :email, :password, :password_confirmation, :remember_me, :company_id
  belongs_to :company
end

当然，这假设您的用户表有一个company_id列(但我猜您已经添加了它，就像您在attr_accessible中列出的那样)
