我有两个表(表 A、表 B)与一个具有 3 个有效负载列的连接表(TableAB)连接。有效负载是指除 Id、TableAId 和 TableBId 之外的列。
我可以成功插入所有表,但我需要将数据插入到 Insert 上的有效负载列之一。我正在使用 EF 4.3,Fluent API。任何人都可以帮忙吗?提前致谢。
public class Organisation : EntityBase<int>, IAggregateRoot
{
public string Name { get; set; }

public int? OwnershipTypeId { get; set; }
public int OrganisationStatusId { get; set; }
public virtual ICollection<Feature> Features { get; set; }
public virtual ICollection<OrganisationType> OrganisationTypes { get; set; }

public class OrganisationUser : EntityBase<int>, IAggregateRoot
{
public DateTime StartDate { get; set; }
public DateTime? EndDate { get; set; }
public int OrganisationRoleId {get; set;}//Foreign Key - have tried leaving it out, tried it as public virtual Organisation Organisation {get;set;
public bool IsApproved { get; set; }
}
public class SDContext : DbContext
{
public ObjectContext Core
{
get
{
return (this as IObjectContextAdapter).ObjectContext;
}
}
public IDbSet<User> User { get; set; }
public IDbSet<Organisation> Organisation { get; set; }
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
modelBuilder.Entity<Organisation>().HasMany(u => u.Users).WithMany(o => o.Organisations).Map(m =>
{
m.MapLeftKey("OrganisationId");
m.MapRightKey("UserId");
m.ToTable("OrganisationUser");
});
//我已经尝试在fluent中专门定义外键,但我真的需要了解如何在访问和编辑它们后添加有效负载属性。
