Question

在我的测试中，我这样做：

     delete :destroy, :id => p.id
     assert_equal "You do not have permission to delete this Object.", flash[:error]
     Object.find_by_id(p.id).should_not be_nil #line 48 (reffed by console output below)

和我之前的过滤器，有一个put，所以我知道结果是false，并且不返回

  before_filter lambda { |controller| 
      result = controller.is_object_on_same_account_as_current_account_for_id?(
                  controller_name.classify.constantize, 
                  controller.params[:id])
      puts result
      return if result
  }, :only => [:destroy]

根据此页面：http://citizen428.net/archives/846，过滤器绑定的操作仅在过滤器返回时执行。

这是控制台输出：

Started
false
F
Finished in 0.865708 seconds.

  1) Failure:
test: .... ...
blah blah, issue is on line 48

     shoulda (2.11.3) lib/shoulda/context.rb:382:in `...']:
expected: not nil
     got: nil

那么......这里发生了什么？我完全无能为力。

相关代码：

破坏方法：

 def destroy
    @content.destroy

不，我只运行一次测试。

根据官方Rails Docs，使用before_filter停止执行操作的正确方法是在过滤器中实际重定向或呈现。

所以你可能想要：

before_filter lambda { |controller| 
      result = controller.is_object_on_same_account_as_current_account_for_id?(
                  controller_name.classify.constantize, 
                  controller.params[:id])
      puts result
      if !result
        flash[:error] = "You do not have permission to delete this Object."
        redirect_to "/" # or wherever you want to redirect to
      end
  }, :only => [:destroy]

RoR：在过滤器返回false之前，不会停止运行表单
