Suppressing Id generation in EF code first. #492

Hi,

Is there anything in the framework that might get in the way of overriding the default name and type for an entities PK please?

Marking a property like this results in the right primary key being defined:

    [Key]
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public Guid SupplierId { get; set; }

However, the EF default of "Id" is still created. Naming a property "<EntityClassName>Id" should suppress this:

Cheers,

Laurie

    Hi,

    You can derive your entity from Entity<TKey> and override Id as shown below:

    public class Supplier : Entity<Guid>
{
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public override Guid Id { get; set; }

    //...your other properties
}

    Entity's primary key must be Id in ABP framework. If you want to map it to a different field in db, you can add a [Column("SupplierId")] to the Id property. But the entity model's id should be Id.

    Thanks hikalkan.

    For those who are interested, to override Id with guid datatype and also implement the full audit log pattern, do this:

    [Table("Supplier")]
public class Supplier : **FullAuditedEntity&lt;Guid&gt;**

{

    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public override Guid Id { get; set; }
