Question

Say I have a role entity and a site entity. Now there are many roles to one site, so on the Role class there is a Site property that represents that relationship. If I wanted the roles for a site I would do this:

Site.Roles.Load() 

Problems is, since the Site property on the Role class isn’t a collection but just a single entity, there is no Load method:

currentRole.Site //???? 

So that when a role is loaded, the Site is null and there is no way to get the site other than say a query on the role collection to get the SiteID, getting the Site from the site collection, and finally setting that to currentRole’s site property.

There has to be a better way? Do I have to force some kind of join in the query? Seems like this would be generated by code just like the Load method behaves.

Answer 1

Accessing it will load it. If you want it to load it explicitly there should be an .Include() method on the object query.

db.Sites.Include('Role').ToList(); 

Here’s some documentation
