PRG在ASP.NET MVC而是转移到重定向操作对象数据 [英] PRG in ASP.NET MVC but with object data transferred to the redirected action

问题描述

继后重定向，获得在最详细的<一个在各个景点描述，但也许格局href=\"http://stephenwalther.com/blog/archive/2008/06/20/asp-net-mvc-tip-6-call-redirecttoaction-after-submitting-a-form.aspx\"相对=nofollow>这里由斯蒂芬·沃尔特，我想用 RedirectToAction 但它不会接受一个参数发送对象给它。我只能发送路由值无论是作为一个对象或作为 RouteValueDictionary 。所以目前我发送对象ID和类型，并在行动再次拉对象从数据存储的，而我重定向（如结果）。

Following the Post-Redirect-Get pattern as described in various spots but maybe in most detail here by Stephen Walter, I want to use RedirectToAction but it does not accept a parameter for sending an object to it. I can only send route values either as an object or as a RouteValueDictionary. So currently I send object ID and type and pull the object out of the datastore again in the action to which I redirected (like Results).

// redirect to confirm view
return RedirectToAction("ChangeSuccess", "Redirect",
    new { slug = tabgroup.Slug, contentType = tabgroup.ContentType });

不过，我想有发送对象，因为我已经在我的更新控制器操作，所以我不需要再拉出来。

But I would like to send an object there because I already have it in my updating controller action so I don't need to pull it out again.

这是可能以某种方式？

推荐答案

请参阅这里。

但我会建议通过刚刚ID。如果以后决定使用延迟加载，保持实体会议将失败（因为会话重定向后消失）。我这个经历过自己，不得不重写许多动作。

But I would recommend to pass just ID. If you later decide to use lazy-loading, keeping entity in session will fail (because session is gone after redirect). I experienced this myself and had to rewrite many actions.
