测试＆QUOT的正确途径;关联＆QUOT;使用RSpec？ [英] Correct way of testing "associations" with Rspec?

问题描述

我想测试以下情形：

- >我有一个叫团队模式，是很有道理的时候就已经由用户创建的。因此，每个队的实例已被相关的用户

-> I have a model called Team which it just makes sense when it has been created by a User. Therefore, each Team instance has to be related to a User.

为了测试这一点，我已经做了以下内容：

In order to test that, I have done the following:

describe Team do

...

  it "should be associated with a user" do
    no_user_team = Team.new(:user => nil)
    no_user_team.should_not be_valid
  end

...

end

这迫使我改变球队模型

为：

Which forces me to change the Team model as:

class Team < ActiveRecord::Base
  # Setup accessible (or protected) attributes for your model
  attr_accessible :name, :user

  validates_presence_of :name
  validates_presence_of :user

  belongs_to :user
end

这看起来正确的吗？我只是担心做出的：用户属性的访问（质量分配）。

Does this seem correct to you? I am just worried of make the :user attribute as accessible (mass assignment).

推荐答案

我通常使用这种方法：

describe User do
  it "should have many teams" do
    t = User.reflect_on_association(:teams)
    t.macro.should == :has_many
  end
end

有一个更好的解决办法是使用宝石早该这将让您只需：

A better solution would be to use the gem shoulda which will allow you to simply:

describe Team do
  it { should belong_to(:user) }
end
