getProperty的1.14.12堆栈(EF6)“未定义不是一个函数”

Question

我收到以下错误：“未定义不是updateRelatedEntityInCollection updateRelatedEntityInCollection中的一个函数

当使用微风叠加1.14.12与EF 6.1 / WebApi2。

我有以下实体/地图定义的服务器端：

public partial class Agency
{
    public Agency()
    {
        this.Programs = new HashSet<AgencyProgram>();
        this.Locations = new HashSet<Location>();
        this.Participants = new HashSet<Participant>();
        this.StaffMembers = new HashSet<Staff>();
    }

    public int Id { get; set; }
    public string Name { get; set; }

    public virtual ICollection<AgencyProgram> Programs { get; set; }
    public virtual ICollection<Location> Locations { get; set; }
    public virtual ICollection<Participant> Participants { get; set; }
    public virtual ICollection<Staff> StaffMembers { get; set; }
}

public partial class Staff
{
    public Staff()
    {
        this.CareerClubs = new HashSet<CareerClub>();
        this.ClassFacilitation = new HashSet<ClassFacilitator>();
    }

    public int AgencyId { get; set; }
    public int Id { get; set; }
    public string Name { get; set; }

    public virtual Agency Agency { get; set; }
    public virtual ICollection<CareerClub> CareerClubs { get; set; }
    public virtual ICollection<ClassFacilitator> ClassFacilitation { get; set; }
}

public class StaffMap : EntityTypeConfiguration<Staff>
{
    public StaffMap()
    {
        // Primary Key
        this.HasKey(t => t.Id);

        // Properties
        this.Property(t => t.Name)
            .IsRequired()
            .HasMaxLength(50);

        // Table & Column Mappings
        this.ToTable("Staff");
        this.Property(t => t.AgencyId).HasColumnName("AgencyId");
        this.Property(t => t.Id).HasColumnName("Id");
        this.Property(t => t.Name).HasColumnName("Name");
    }
}

public class AgencyMap : EntityTypeConfiguration<Agency>
{
    public AgencyMap()
    {
        // Primary Key
        this.HasKey(t => t.Id);

        // Properties
        this.Property(t => t.Name)
            .IsRequired()
            .HasMaxLength(50);

        // Table & Column Mappings
        this.ToTable("Agency");
        this.Property(t => t.Id).HasColumnName("Id");
        this.Property(t => t.Name).HasColumnName("Name");
}

当我查询控制器是否有代理时(没有过滤器，只需要

return context.Agencies

我要拿回下面的Json

[{"$id":"1","$type":"System.Data.Entity.DynamicProxies.Agency_09777AD4C70881ED42DD78FB209FCD42C4995B1603097BBFD98C061405E71961, EntityFrameworkDynamicProxies-Model.Persistence","Locations":[],"Participants":[],"Programs":[],"StaffMembers":[{"$id":"2","$type":"System.Data.Entity.DynamicProxies.Staff_B3294F308AC9ED853C9E99FE2B1D765F9433E16FF56372757A43E397DECA38C7, EntityFrameworkDynamicProxies-Model.Persistence","Agency":{"$ref":"1"},"CareerClubs":[],"ClassFacilitation":[],"AgencyId":4,"Id":5,"Name":"Samuel Gonzalez"}],"Id":4,"Name":"Test Agency\r\n"}]

任何时候，Breeze‘type’结果(无论是用toType还是如果我设置元数据映射)，都会引发此错误。relatedEntity for updateRelatedEntityInCollection是一个填充的Staff对象，没有简单的道具(没有EntityAspect)，inverseProperty associationName是Staff_Agency。

我想无论出于什么原因，Staff对象在从服务器返回后不会得到“轻松化”。

动态代理是问题所在。您需要关闭它们，或者使用Breeze的EFContextProvider，它可以正确地配置事物。

微风通过"$type“属性识别实体，当使用代理时，该属性将变得不可识别。
