[英]Return the right parent's `get` after a child `post` action
我在幾個父母的動作中都有相同的子動作,讓我們說有兩個父視圖:
@model Parent1Model
@{
ViewBag.Title = "Parent1";
Layout = "~/Views/Shared/_Layout.cshtml";
}
@Html.Action("Child","MainControler")
第二個父母:
@model Parent2Model
@{
ViewBag.Title = "Parent2";
Layout = "~/Views/Shared/_Layout.cshtml";
}
@Html.Action("Child","MainControler")
所有操作都放在同一個控制器中。
public ActionResult parent1() //GET
{
Parent1Model model = new Parent1Model()
return View(model );
}
public ActionResult parent2() //GET
{
Parent2Model model = new Parent2Model()
return View(model );
}
public ActionResult Child() //GET
{
ChildModel model = new ChildModel()
return View(model );
}
[HttpPost]
public ActionResult Child(ChildModel model) //POST
{
DoThingsWithResult(model)
// The next line should return the get of the parent action
return RedirectToParent() // This does not exist...
}
現在,我該如何告訴孩子給他父母的GET
打電話? 作為許多父母的孩子,他怎么能知道哪一位家長這次稱呼它?
我找不到任何東西,谷歌和“可能已經有你的答案的問題”。
您可以添加一個參數來確定它的來源,您也可以將此參數設置為一個字符串,該字符串將成為父操作名稱本身並將該參數傳遞給RedirectToAction(param)
防爆
[HttpPost]
public ActionResult Child(string ParentName, ChildModel model) //POST
{
DoThingsWithResult(model)
// The next line should return the get of the parent action
return RedirectToAction(ParentName) // This does not exist...
}
在您的父動作中
public ActionResult parent2() //GET
{
Parent2Model model = new Parent2Model();
ViewBag.Parent = "parent2";
return View(model );
}
在你看來
@model Parent2Model
@{
ViewBag.Title = "Parent2";
Layout = "~/Views/Shared/_Layout.cshtml";
}
@Html.Action("Child","MainControler", new {ParentName= ViewBag.Parent})
為父母行動1做同樣的事情
