控制器作为 ascx 工厂 - 坏主意？
我正在尝试创建类似 *.ascxs' 工厂的东西。
设想： 我想渲染取决于模型的控件，我已将其传递给partialView。 我想实现这样的目标：
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<MyAbstractModel>" %>
<%= Model.Property1 %>
<!-- other more sophisticated displays on model -->
<% Html.RenderAction("RenderControl", "Factory", new { model = Model}); %>
FactoryController：
public ActionResult RenderControl(object model) {
if (model.GetType() == typeof(Model1) {
return RenderPartial("Partial2", model);
} else {
return RenderPartial("Partial1", model);
}
}
我想知道是否有更好的方法来应对这种情况。我想这不是在 ASP.MVC 2 中构建网页的最有效方法。
如果这种方法可以接受，我如何限制对此类控制器的访问？我想仅在服务器端且仅通过 ascxs 页面使用此类
I'm trying to create something like *.ascxs' factory.
Scenario:
I would like to render controls which depends on model, which i've passed to partialView.
I'd like to achieve something like this:
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<MyAbstractModel>" %>
<%= Model.Property1 %>
<!-- other more sophisticated displays on model -->
<% Html.RenderAction("RenderControl", "Factory", new { model = Model}); %>
FactoryController:
public ActionResult RenderControl(object model) {
if (model.GetType() == typeof(Model1) {
return RenderPartial("Partial2", model);
} else {
return RenderPartial("Partial1", model);
}
}
I'd like to know is there any better way to cope with such situation. I suppose It's not the most efficient method to build web page in ASP.MVC 2.
If this method is acceptable, how can i restrict access to such controller? I would like to use this class only on server side and only by ascxs' pages

使用
ChildActionOnly()属性来限制对操作的访问。您想要做的事情已经内置到 MVC 中：
Html.DisplayFor()请参阅：http://bradwilson.typepad.com/blog/2009/10/aspnet-mvc-2-templates-part-1-introduction.html
Use the
ChildActionOnly()attribute to restrict access to your actions.What you are trying to do is already builtin to MVC:
