在playframework中有可能覆盖CRUD控制器中的默认保存操作，并重定向到列表之后 [英] Is it possible in playframework to override the default save action in the CRUD controller and redirect to list after

问题描述

我使用Play框架的伟大crud模块。事情是我想在我的对象被保存之前做一些特殊的处理和验证。所以我在我的CRUD控制器中创建了一个保存操作。到现在为止还挺好。但现在在对象被保存后，我想渲染对象列表，就像CRUD模块在我覆盖它的保存操作之前做的。

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?

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
     }

}

我尝试过不同的东西，如 parent（） [Deprecated ]不是我想要的。我尝试了 CRUD.list（）但我需要传递我没有的参数。我也试过 render（admin / Categories / List.html，??????）; 但我需要传递一个列表，我不知道什么

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.

任何帮助将不胜感激。

推荐答案

在正确的道路上。最后只需调用 redirect（request.controller +.list）; 它应该工作。

You're on the right path. At the end just call redirect(request.controller + ".list"); It should work.
