ruby-on-rails - 轨attr_accessible rspec的检查

Question

当我想测试属性是否为/时 无障碍 使用 RSpec 我就是这样做的

class Foo
  attr_accesible :something_else
end

describe Foo do
  it('author should not be accessible')    {lambda{described_class.new(:author=>true)}.should raise_error ActiveModel::MassAssignmentSecurity::Error}
  it('something_else should be accessible'){lambda{described_class.new(:something_else=>true)}.should_not raise_error ActiveModel::MassAssignmentSecurity::Error}
end

有没有更好的方法呢？

...谢谢

This is the way attribute accessibility tests are done in the Rails Tutorial ，我觉得还不错。因此，在您的情况下，可以稍微修改测试代码，如下所示:

describe Foo do
  describe "accessible attributes" do
    it "should not allow access to author" do
      expect do
        Foo.new(author: true)
      end.to raise_error(ActiveModel::MassAssignmentSecurity::Error)
    end

    it "should allow access to something_else" do
      expect do
        Foo.new(something_else: true)
      end.to_not raise_error(ActiveModel::MassAssignmentSecurity::Error)
    end
  end
end

如果这不是您想要的，当您询问是否有“更好的方法”时，您能否让我们更好地了解您所追求的解决方案？

您可能对 Shoulda ActiveModel matchers 感兴趣，这会将代码清理为每个测试仅一行。就像是:

it { should_not allow_mass_assignment_of(:author) }
it { should allow_mass_assignment_of(:something_else) }
