playframework 是否可以覆盖 CRUD 控制器中的默认保存操作并重定向到列表

我正在使用 Play 框架的出色的 CRUD 模块。问题是我想在保存我的对象之前进行一些特殊的处理和验证。所以我在 CRUD 控制器中创建了一个保存操作。到目前为止，一切都很好。但现在保存对象后，我想渲染对象列表，就像在覆盖其保存操作之前 CRUD 模块所做的那样。我该怎么做呢？

这是我的控制器：

package controllers.admin;

import java.util.List;

import models.Category;
import controllers.CRUD;

@CRUD.For(Category.class)
public class Categories extends CRUD {

     public static void save(Long id, Category category) {
         // Do my custom save process here

         //Redirect to the list page like CRUD was doing before I created this save action
     }

}

我尝试了不同的东西，例如 parent() [已弃用]，这不是我想要的。我尝试了 CRUD.list() 但我需要传递我没有的参数。我还尝试了 render(admin/Categories/List.html, ??????); 但我需要传递一个列表，但我不知道该怎么称呼它。

任何帮助将不胜感激。

I'm using Play framework's great crud module. The thing is I would like to do some special processing and validation before my object gets saved. So I created a save action in my CRUD controller. So far so good. But now after the object is saved I would like to render the list of objects just like the CRUD module was doing before I overrode its save action. How would I go about doing this?

Here is my controller:

package controllers.admin;

import java.util.List;

import models.Category;
import controllers.CRUD;

@CRUD.For(Category.class)
public class Categories extends CRUD {

     public static void save(Long id, Category category) {
         // Do my custom save process here

         //Redirect to the list page like CRUD was doing before I created this save action
     }

}

I tried different things like parent() [Deprecated] not what I wanted. I tried CRUD.list() but I need to pass parameters which I don't have. I also tried render(admin/Categories/List.html, ??????); but I would need to pass a list and I don't know what to call it.

Any help would be appreciated.
