I've got some objects that look like this:
abstract public class Field
{
public int Id { get; set; }
public string Name { get; set; }
public int Ordinal { get; set; }
}
[Table("DropDownField")]
public class DropDownField : Field
{
public virtual List<FieldOption> Options { get; set; }
}
[Table("RadioButtonField")]
public class RadioButtonField : Field
{
public virtual List<FieldOption> Options { get; set; }
}
public class FieldOption
{
public int Id { get; set; }
public string Name { get; set; }
public string Value { get; set; }
}
In my database, it ends up creating the a FieldOptions table using Code First. However, it creates the following columns:
What I'd like to see is just one Field_Id in this table since the Id of a field has to be unique across the different types of fields.
Is there a way to do this? I've done some searching but I must not know the right search terms to use to find the answer.
imho, what you want, from a relational database point of view, is a column (Option.FieldId) being a foreign key to 2 tables DropDownField and RadioButtonField.
That is whenever you insert an option, FieldId must reference an existing DropDownField AND an existing RadioButtonField.
That is at least weird.
I don't think this can/should be achieved.
