Question

您好我正在尝试在多上下文项目中启用迁移。我收到这个错误：

在模型生成期间检测到一个或多个验证错误： Mellon.Pricing.RiskControl.Migrations.RetornoValidacao :: EntityType＆＃39; RetornoValidacao＆＃39;没有定义键。定义此EntityType的密钥。

事情是在上下文中没有这样的DBSet。

代码如下：

 public partial class RiskControlContext : DbContext
 {
  public RiskControlContext()
  : base("RiskControlContext")
{
}

#region Repositorios

IDbSet<DeParaCurvas> _deParaCurvas;
public IDbSet<DeParaCurvas> DeParaCurvas
{
  get { return _deParaCurvas ?? (_deParaCurvas = base.Set<DeParaCurvas>()); }
}

IDbSet<DeParaPrecos> _deParaPrecos;
public IDbSet<DeParaPrecos> DeParaPrecos
{
  get { return _deParaPrecos ?? (_deParaPrecos = base.Set<DeParaPrecos>()); }
}

IDbSet<PrecoRiskControl> _precoRiskControl;
public IDbSet<PrecoRiskControl> PrecoRiskControl
{
  get { return _precoRiskControl ?? (_precoRiskControl = base.Set<PrecoRiskControl>()); }
}

IDbSet<VerticeRiskControl> _verticeRiskControl;
public IDbSet<VerticeRiskControl> VerticeRiskControl
{
  get { return _verticeRiskControl ?? (_verticeRiskControl = base.Set<VerticeRiskControl>()); }
}

#endregion


protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
  //Remover as conventions que não são usadas
  modelBuilder.Conventions.Remove<OneToManyCascadeDeleteConvention>();

  //Adiciona a configuração das entidades de maneira estruturada usando as classes 'TypeConfiguration' em Mapping
  modelBuilder.Configurations.Add(new DeParaPrecosConfiguration());
  modelBuilder.Configurations.Add(new DeParaCurvasConfiguration());
  modelBuilder.Configurations.Add(new PrecoRiskControlConfiguration());
  modelBuilder.Configurations.Add(new VerticeRiskControlConfiguration());

}

}

我解决了这个问题。错误消息绝对是错误的。

延迟加载引用实体“DeParaPreco”中的另一个项目是一个问题所以我通过添加

来解决

this.Ignore（e =＆gt; e.Ativo）;

EntityTypeConfiguration

中的
