I cannot for the life of me get two separate tables to save with a relationship and two
identity columns. I keep getting errors like A dependent property in a ReferentialConstraint is mapped to a store-generated column. Column: 'OlsTerminalId'. I can't imagine that this setup is abnormal.
[DataContract]
public class OlsData {
private static readonly DateTime theUnixEpoch = new DateTime(1970, 1, 1, 0, 0, 0, 0, DateTimeKind.Utc);
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int OlsDataId { get; set; }
[DataMember(Name = "id")]
public int Id { get; set; }
public DateTime Timestamp { get; set; }
[DataMember(Name = "created")]
[NotMapped]
public double Created {
get { return (Timestamp - theUnixEpoch).TotalMilliseconds; }
set { Timestamp = theUnixEpoch.AddMilliseconds(value); }
}
[InverseProperty("OlsData")]
[DataMember(Name = "terminal")]
public virtual OlsTerminal OlsTerminal { get; set; }
}
[DataContract]
public class OlsTerminal {
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int OlsTerminalId { get; set; }
public int OlsDataId { get; set; }
[DataMember(Name = "account")]
[NotMapped]
public virtual OlsAccount OlsAccount { get; set; }
[DataMember(Name = "terminalId")]
public string TerminalId { get; set; }
[DataMember(Name = "merchantId")]
public string MerchantId { get; set; }
public virtual OlsData OlsData { get; set; }
}
public class OlsDataContext : DbContext {
protected override void OnModelCreating(DbModelBuilder aModelBuilder) {
aModelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
}
public OlsDataContext(string aConnectionString) : base(aConnectionString) {}
public DbSet<OlsData> OlsData { get; set; }
public DbSet<OlsTerminal> OlsTerminal { get; set; }
public DbSet<OlsAccount> OlsAccount { get; set; }
}
