Getting the Part value for the Site content item

I'm extending the Settings -> General section of the admin page to include an Enumeration Field called Erp. To do this I'm using this code in the migration:
            ContentDefinitionManager.AlterPartDefinition("Erp", part => part
                .WithField("ErpEngine", field =>
                                        new[] {"Default", "SAP", "Dynamics AX"}))));

            ContentDefinitionManager.AlterTypeDefinition("Site", builder => builder
This displays correctly and saves correctly too.

Now I want to get that selected value from inside of a driver. I can get the Site content item with:
var site = _contentManager.Query().ForType("Site").List(); 
But debugging through this, I can't see anything that resembles my Erp Field. Where would this be?

Can you see the part?

I can see the part through the admin, yes. It appears as: "Erp Engine (Enumeration Field)".

Under "Edit Content Type - Site" I can also see it as:


ErpEngine (EnumerationField)

An option is required
Check to ensure the user is providing an option for this field.

Dynamics AX

Enter an option per line.
List mode
Dropdown list

Help text.... etc...
I can also see it at the bottom on my Settings -> General page, under "Default number of items per page"

It appears as a dropdown list, with the three options in it, and persists when I click save.

I meant in the debugger.

Adding a qucikwatch to the line:

var site = _contentManager.Query().ForType("Site").List();

Gives me this:

What's under the one called "contentpart"? you should be able to drill to the field from that one. What happens when you enumerate the fields for that part?

Ah neat!

I had to go through linq hell to get what I wanted, but here's the result:
            var site = _contentManager.Query().ForType("Site").List();
            var contentPart = site.FirstOrDefault().Parts.FirstOrDefault(p => p.GetType() == typeof(ContentPart));
            var enumField = (Orchard.Fields.Fields.EnumerationField)contentPart.Fields.FirstOrDefault(f => f.Name == "ErpEngine");

            if (enumField.Value == "Dynamics AX") //do something...;

You should be able to do:
dynamic site =  _contentManager.Query().ForType("Site").List().First();
var enumField = site.Site.ErpEngine;

I can't get that to work. In Orchard.InvokeExtensions it throws:
{"'Orchard.ContentManagement.ContentItem' does not contain a definition for 'Site'"}

My mistake. Should be site.Erp.ErpEngine

Ah, nice, I should have guessed that!
