We are still waiting for the code to be released by Microsoft, but in the meantime I thought I would post up an extremly preliminary idea of what the DomainController might look like. In this case, it is the DbDomainController:
public class AddressBookDomainController : DbDomainController<AddressBookContext>
{
protected override void OnDomainCreating(DbDomainBuilder<AddressBookContext> domainBuilder)
{
domainBuilder.Repositories.Add<AddressRepository>()
.RequiresRole(OperationType.All, "AddressEditor")
.RequiresRole(OperationType.Read, "ContactViewer");
domainBuilder.Repositories.Add<PersonRepository>()
.RequiresRole(OperationType.All, "PersonEditor")
.RequiresRole(OperationType.Read, "ContactViewer");
}
}
The DomainController
can look just like the DomainService does with all of the individual CRUD methods in the body, but you will also be able to register repositories with the DomainController and have the CRUD methods picked up from the repository. This is what the repository would look like:
public class PersonRepository
{
AddressBookContext Context {get;set;}
public PersonRepository(AddressBookContext context)
{
Context = context;
}
public IQueryable<Person> GetPeople
{
return Context.Persons;
}
public void InsertPerson(Person entity)
{
DbEntityEntry<LoadRating> entityEntry = this.Context.Entry(entity);
if ((entityEntry.State != EntityState.Detached))
{
entityEntry.State = EntityState.Added;
}
else
{
this.Context.People.Add(entity);
}
}
public void UpdatePerson(Person currentPerson)
{
this.Context.People.AttachAsModified(currentPerson, this.Context);
}
public void DeletePerson(Person entity)
{
DbEntityEntry<Person> entityEntry = this.Context.Entry(entity);
if ((entityEntry.State != EntityState.Detached))
{
entityEntry.State = EntityState.Deleted;
}
else
{
this.Context.People.Attach(entity);
this.Context.People.Remove(entity);
}
}
}
