在 Orchard 中使用 FindView [英] Using FindView in Orchard

问题描述

我正在尝试使用:

var viewEngineResult = ViewEngines.Engines.FindView(ControllerContext, myViewName, null);

作为渲染视图内容以发送格式良好的电子邮件的过程的一部分.我在果园控制器中使用它.我在 MVC 项目中使用了 Orchard 之外的类似代码，并且运行良好.

as part of a process to render the contents of a view to send nice formatted emails. I'm using it inside an Orchard Controller. I have used similar code outside of Orchard in an MVC project and it works fine.

但是在 Orchard 中运行此代码无法找到我正在寻找的视图并返回搜索了 0 个位置的视图引擎结果.

However in Orchard running this code fails to find the view I'm looking for and returns a view engine result that has searched 0 locations.

viewEngineResult 被调用后具有以下值:

viewEngineResult has the following values after it is called:

• SearchedLocations: Count = 0,
• 视图:空，
• 视图引擎:空

这是否有原因在 Orchard 中不起作用?有没有办法让它起作用?

Is there a reason this doesn't work in Orchard and is there a way to make it work?

推荐答案

我想你应该仔细看看 Orchard.Framework/Mvc/ViewEngines，特别是 IViewEngineProvider 和 ThemeAwareViewEngine.在 Orchard 中还有很多事情要做，例如主题、多租户和更丰富的环境，这些通常可能需要使这项工作发挥作用.这里可能发生的情况是视图引擎没有足够的信息来解析视图，因此选择退出链.您可能希望在 ThemeAwareViewEngine.FindView 中放置一个断点，然后检查该类的私有依赖项字段.如果它们为空，我不会感到惊讶，因为通过静态获取 FindView 可能不允许依赖注入正确地完成它的工作.再说一次，我只是猜测.

I think you'll want to take a close look at Orchard.Framework/Mvc/ViewEngines, in particular IViewEngineProvider and ThemeAwareViewEngine. There's a lot more going on when in Orchard, such as themes, multi-tenancy, and a richer environment in general that may be needed to make this work. What's likely happening here is that the view engines don't have enough information to resolve a view and thus opt out of the chain. You might want to put a breakpoint into ThemeAwareViewEngine.FindView, and then inspect the private dependency fields of that class. I wouldn't be surprised if they were null, because getting to FindView through statics will probably not allow dependency injection to do its stuff properly. Then again I'm just guessing.
