How to convert a Sitecore Item object into a strongly-typed Glass model?

Question

I have a Sitecore template MyTemplate and a corresponding Glass model MySite.Model.MyTemplate.

In my page code, I retrieve a raw Sitecore.Data.Items.Item object from a legacy data access class. This object represents an item of the template MyTemplate, but it is still a generic item object, so I have to access its fields like this: item["FieldName"].

Is there a quick way to convert this Item object into a strongly-typed Glass model of the class MySite.Model.MyTemplate? I want to do this directly in my page code, without replacing the way in which I obtain the item object.

Answer 1

Instantiate a SitecoreContext and call the Cast<T>() method.

ISitecoreContext context = SitecoreContext.GetFromHttpContext();
var myTemplateObject = context.Cast<MySite.Model.MyTemplate>(item);

Answer 2

Looks like SitecoreContext.GetFromHttpContext() is obsolete.

The recommend way is SitecoreContextFactory.Default.GetSitecoreContext()

My preferred way is new SitecoreContext()

So casting can be done like:

var model = SitecoreContextFactory.Default.GetSitecoreContext().Cast<T>(item);
var model = new SitecoreContext().Cast<T>(item);

Answer 3

I'm not sure if this is GlassMapper specific but this works for me in my 9.1

SitecoreService context = new SitecoreService(Sitecore.Context.Database);
MyModel rule = context.GetItem<MyModel>(item);
