I'm trying (and failing) to get property injection working in Orchard CMS.
This is necessary, because the below code is acting something like a code-behind for a view (horrible I know). The reason being that the view doesn't have a controller that I can use constructor injection on, because this is an alternate view for a MenuItem
, i.e. MenuItemLink-MyCustomMenuItem.cshtml
.
Not much more to say than that, except what's in the comments (note the NULL comment for the property that I am trying to set in the code below).
Oh, I've also tried adapting the property injection code from Orchard's LoggingModule
, but equally that doesn't work for me either.
How do I :
a. get the below property injection to work? (I'm pretty sure I will need it at some point regardless)
b. (if possible) get my own controller/driver in the way of the view so I can use constructor injection on the controller instead?
using System.Diagnostics;
using System.Xml.Linq;
using Autofac;
using Autofac.Core;
using Orchard;
using Module = Autofac.Module;
namespace MyCo.MyCustomMenuItem.Services
{
public class MyCustomMenuItemModule : Module
{
protected override void AttachToComponentRegistration(
IComponentRegistry componentRegistry,
IComponentRegistration registration)
{
if (implementationType.ToString() ==
"MyCo.MyCustomMenuItem.Services.MyCustomMenuItem")
{
// this does get called, but doesn't have the desired effect
registration.Activated += (s, e) =>
e.Context.InjectUnsetProperties(e);
}
}
}
public interface IFeedX : IDependency
{
XDocument GetResource();
}
public class FeedX : IFeedX
{
public XDocument GetResource()
{
return new XDocument();
}
}
public interface IMyCustomMenuItem : IDependency
{
XDocument GetResourceData();
IFeedX FeedX { get; set; }
}
public class MyCustomMenuItem : IMyCustomMenuItem
{
public IFeedX FeedX { get; set; }
// called direct by razor view
public XDocument GetResourceData()
{
Debug.WriteLine(FeedX); // NULL??
return FeedX.GetResource();
}
}
}
You definitely should not do anything of the sort in the view. I think this article describes a scenario that is close to what you're trying to achieve: http://www.davidhayden.me/blog/dynamically-injecting-menu-items-in-orchard-cms
