如何在 RSpec 中测试 attr_accessible 字段 [英] How to test attr_accessible fields in RSpec

问题描述

因此，我们在 Rails 3.2 应用程序中的许多字段上设置了 attr_accessible 和 attr_protected.目前我们确实没有测试以确保这些字段受到保护.

So we have been setting up attr_accessible and attr_protected on many fields through out our Rails 3.2 app. For now we really don't test to ensure that these fields are protected.

所以我决定在谷歌上搜索一些答案并偶然发现了这个解决方案:

So I decided to google some answers and stumbled upon this solution:

RSpec::Matchers.define :be_accessible do |attribute|
  match do |response|
    response.send("#{attribute}=", :foo)
    response.send("#{attribute}").eql? :foo
  end
  description { "be accessible :#{attribute}" }
  failure_message_for_should { ":#{attribute} should be accessible" }
  failure_message_for_should_not { ":#{attribute} should not be accessible" }
end

但此解决方案仅测试该方法是否有响应.我需要的是一种让我测试属性可以和不能批量分配的方法.老实说，我喜欢语法

But this solution only test's to see if the method is responding. What I need is a way for me to test that attributes can and can't be mass assigned. I honestly love the syntax

it { should_not be_accessible :field_name }
it { should be_accessible :some_field }

有没有人对这个问题有更好的解决方案?

Does anyone have a better solution to this problem?

推荐答案

您可以检查该属性是否在#accessible_attributes列表中

You can check if the attribute is on #accessible_attributes list

RSpec::Matchers.define :be_accessible do |attribute|
  match do |response|
    response.class.accessible_attributes.include?(attribute)
  end
  description { "be accessible :#{attribute}" }
  failure_message_for_should { ":#{attribute} should be accessible" }
  failure_message_for_should_not { ":#{attribute} should not be accessible" }
end
