If I select from an IQueryable then the Include is lost
- by Connor Murphy
The include does not work after I perform a select on the IQueryable query.
Is there a way arround this? My query is
public IQueryable<Network> GetAllNetworks()
{
var query = (from n in _db.NetworkSet
.Include("NetworkContacts.Contact")
.Include("NetworkContacts.Contact.RelationshipSource.Target")
.Include("NetworkContacts.Contact.RelationshipSource.Source")
select (n));
return query;;
}
I then try to populate mya ViewModel in my WebUI layer using the following code
var projectedNetworks =
from n in GetAllNetworks()
select new NetworkViewModel
{
Name = n.Name,
Contacts = from contact in networkList
.SelectMany(nc => nc.NetworkContacts)
.Where(nc => nc.Member == true)
.Where(nc => nc.NetworkId == n.ID)
.Select(c => c.Contact)
select contact,
};
return projectedNetworks;
The problem now occurs in my newly createdNetworkViewModel
The Contacts object does include any loaded data for RelationshipSource.Target or RelationshipSource.Source
The data should is there when run from the original Repository IQueryable object. However the related include data does not seem to get transferred into the new Contacts collection that is created from this IQueryable using the Select New {} code above. Is there a way to preserve this Include data when it gets passed into a new object?
