Question

  context "can have 2 companies associated with it(v2)" do
    it "should have an error when multiple companies can't belong to an industry " do
        @company1 = Factory(:company)
        @company2 = Factory(:company)
        @industry = Factory(:industry)
        @company1.industry = @industry
        @company2.industry = @industry
        @industry.should have(2).companies
    end
  end

这个测试失败了，我很难用它。其他15项测试都可以。问题是当我尝试使用相关对象时。

我的模特是：

class Company < ActiveRecord::Base
  belongs_to :industry
  validates_presence_of :name
  validates_length_of :state, :is => 2, :allow_blank => true
  validates_length_of :zip, :maximum => 30, :allow_blank => true
end
class Industry < ActiveRecord::Base
  has_many :companies
  validates_presence_of :name
  validates_uniqueness_of :name
  default_scope :order => "name asc"
end

只是插入记录本身似乎没问题 -

  context "can have 2 companies associated with it" do
    it "should have an error when multiple companies can't belong to an industry " do
      lambda do
        @company1 = Factory(:company)
        @company2 = Factory(:company)
        @industry = Factory(:industry)
        @company1.industry = @industry
        @company2.industry = @industry
      end.should change(Company, :count).by(2)
    end
  end

btw我的规格的顶部是：

require 'spec_helper'
describe Industry do
  before(:each) do
    @industry = Factory(:industry)
  end

我也注释掉了

#  config.use_transactional_fixtures = true

位于spec/spec_helper.rb的底部，但没有帮助

如果公司属于一个行业，那么当你创建一家公司时，它就会为每个公司创造一个行业。

您可以通过将行业设置为公司来解决这个问题，但是您没有保存它们。或者，您可以：

before do
  @industry = Factory(:industry)
  @company1 = Factory(:company, :industry => @industry)
  @company2 = Factory(:company, :industry => @industry)
end

it "should have both companies" do
  @industry.companies.should == [@company1, @company2]
end
