Unable to retrieve a single entity
advertisements
I'm trying to retrieve a single entity by its ID in the DomainService.
However the type of that entity is not generated in the client. Here is my query:
public Contact GetContact(int contactId)
{
return DbContext.Contacts
.Include(c => c.Phones)
.Include(c => c.Addresses)
.SingleOrDefault(c => c.ContactId == contactId);
}
The Phone entity isn't generated on the client.
I tried decorating this method with [Query], but then I get the following compile-time exception:
Query operation 'GetContact' cannot be marked composable since its return type 'Models.Contact' does not implement IEnumerable of T.
Is there any way to create a WCF RIA query that returns a single entity by ID?
Setting the IsComposable property will allow it to build. But as in our discussion, I don't know why your Phone and Address entities are not being generated.
[Query(IsComposable=false)]
public Contact GetContact(int contactId)
{
return DbContext.Contacts
.Include(c => c.Phones)
.Include(c => c.Addresses)
.SingleOrDefault(c => c.ContactId == contactId);
}
