I currently have the following classes in my EF based project. Data is stored in a SQL Database using the Table per Hierarchy (TPH) configuration :
class Lot {
Building building
...
}
class Building {
string name {get; set;}
string address {get; set;}
string discriminator {get; set;}
...
}
class House : Building {
...
}
class Employee: {
Building building {get; set;}
Person person {get; set;}
string jobName {get; set;}
}
class Shop: Building {
List<Employee> employees {get; set;}
Person owner {get; set;}
...
}
class Factory: Building {
List<Employee> employees {get; set;}
List<Machine> equipment {get; set;}
...
}
I setup my ef model this way using Ardalis clean architecture configuration classes:
...
builder.HasMany(x => ((Shop)x).employees).WithOne(x => x.building);
builder.HasDiscriminator(x => x.discriminator)
.HasValue<House>("House")
.HasValue<Shop>("Shop")
.HasValue<Factory>("Factory");
Finally in my lot specification where I need to access all the informations I include all the stuff I should need to access
Query.Include(x => x.building).ThenInclude(x => (x as Shop).employees).ThenInclude(x => x.person)
My relationships between the Lot and Building works properly, but the one between Shop and Employees doesn't. Would you have any idea how to make it work? I need an employee list in both Shop and Factory and both are too different to be in a same class.
I tried to make a ModelBuilder for the Shop class specifically that would define the relationship between Shop but it also didn't worked properly. I also try to swap between different type of cast for Building to Shop.
