Ruby on Rails：2.3.8，過濾器自定義之前不工作？

所以，我一直在試圖設置一個before_filter來檢查是否有人可以刪除一個對象的權限。但是，一直沒有工作......最終我做到以下幾點：Ruby on Rails：2.3.8，過濾器自定義之前不工作？

before_filter :test_hack, :only => :destroy 

    def test_hack 
    return false 
    end

destroy方法在這裏：

def destroy 
    @content = Content.find(params[:id]) 

#will get rid of this when the before filter works... 
# but this doesn't stop it from getting deleted either 
    if not has_permission_to_change?(@content) 
     puts "This content is not gonig to get deleted" 
     flash[:error] = 'You do not have permission to delete this content.' 
    else 
     @content.destroy 
    end

失敗的測試：

should "not allow the deleting of #{plural_name} on different accounts" do 
     login_as(@user) 
     p = Factory(factory_name, :account => Factory(:account)) 

     assert_difference("#{klass}.count", 0) do 
     begin 
      delete :destroy, :id => p.id 
      raise "program flow should not reach this message" 
     rescue ActiveRecord::RecordNotFound 
      assert true 
     end 
     end

有人回答你的其他問題：http://stackoverflow.com/questions/6683113/ruby-on-rails-2-3-8-freaking-destroy-behavior-ignores-before-filter – ryeguy

@ryeguy：謝謝，我剛剛;） – apneadiving

Once again，測試的bahavior完全是正常現象：

你行raise "program flow should not reach this message"就一定會執行，因爲存在與物體id傳遞：您剛纔創建它

你應該保持：

assert_difference("#{klass}.count", 0) do 
    delete :destroy, :id => p.id 
    end

我an't看到你before_filter在這裏有用

在您的測試，

delete :destroy, :id => p.id

不會產生任何異常，所以執行繼續正常，在到達下一行

raise "program flow should not reach this message"

和測試失敗，因爲這不是抓。 before_filter與它無關，根據測試輸出，它甚至沒有被調用。
