編輯 - 重新定義的問題，其中包括額外的特定代碼在Symfony2中填充複選框基於ArrayCollection的（）
在我的Symfony2項目，我有一個包括與另一個實體的一對多關係（一個實體（配置） 配置特徵）。我試圖構建一個表單，允許用戶更改配置實體中的值，並選擇要保存到配置實體的值。有兩種使用表單的方案：
1）創建一個新配置 - >呈現一個空白表單，其中包含Configurations中值的字段以及ConfigurationsFeatures中潛在值的複選框的集合;潛在價值的來源實際上是第三個實體，CoreCodes。驗證後，表單的Configurations-values將持久保存到Configurations實體，並將選中的複選框保存到ConfigurationsFeatures。
2）更新現有的配置 - >渲染配置的現有值的形式顯示在字段和渲染複選框的集合的所有可能的值ConfigurationsFeatures BUT已經選擇的現有值。
我已經爲場景＃1構建了窗體類型和控制器操作，並對其進行了測試，並且所有工作都正常。但是，我似乎無法解決表單的複選框部分中的「已有值已選擇」。我意識到，因爲我目前已經設置了我的控制器，所以我基本上將蘋果與桔子進行比較，因爲$ entity-> getFeatures（）返回ConfigurationsFeatures實體的ArrayCollection，並且沒有任何可映射的形式，因爲表單使用CoreCodes實體的集合。
那麼我該如何填補這個空白？
