無效的對象名稱'dbo.AspNetUserAspNetRoles'

Question

使用實體框架處理我的第一個MVC5項目。當我加載用戶並嘗試訪問他們所在的角色時，延遲加載正嘗試從AspNetUserAspNetRoles加載。該表實際上命名爲AspNetUserRoles，我認爲它是默認的，並且在向用戶添加角色時工作正常。我的DBA爲我設置了最初的模型集合，並且正在參加一個會議。我想我可能會在我的DBContext中丟失一些東西，但一小時後我仍然在尋找一個很好的參考來解決我的問題。

這是我的AspNetUser模型。我消除了一些其他的關係，以節省空間

public partial class AspNetUser : IBusinessObject 
{ 
    public AspNetUser() 
    { 
     this.AspNetRoles = new List<AspNetRole>(); 
    } 

    public string Id { get; set; } 
    public string UserName { get; set; } 
    public string PasswordHash { get; set; } 
    public string SecurityStamp { get; set; } 
    public string Discriminator { get; set; } 
    public string FirstName { get; set; } 
    public string LastName { get; set; } 
    public string Email { get; set; } 
    public System.DateTime CreatedOn { get; set; } 
    public System.DateTime UpdatedOn { get; set; } 
    public string CreatedByUserId { get; set; } 
    public bool IsDeleted { get; set; } 
    public string ResetPasswordKey { get; set; } 
    public Nullable<System.DateTime> ResetPasswordKeyExpiration { get; set; } 
    public virtual ICollection<AspNetRole> AspNetRoles { get; set; } 

    public void SoftDelete(bool reverse = false) 
    { 
     IsDeleted = !reverse; 
    } 

} 

這裏是AspNetRole模型

public partial class AspNetRole : INameable, IBusinessObject 
{ 
    public AspNetRole() 
    { 
     this.AspNetUsers = new List<AspNetUser>(); 
    } 

    public string Id { get; set; } 
    public string Name { get; set; } 
    public virtual ICollection<AspNetUser> AspNetUsers { get; set; } 

} 

，這裏是我的DbContext

public partial class SdContext : DbContext 
    { 
     static SdContext() 
     { 
      Database.SetInitializer<SdContext>(null); 
     } 

     public SdContext() 
      : base("SdConnection") 
     { 
     } 

     public DbSet<Cluster> Clusters { get; set; } 
     public DbSet<CoLabDate> CoLabDates { get; set; } 
     public DbSet<CoLabLocation> CoLabLocations { get; set; } 
     public DbSet<CoLab> CoLabs { get; set; } 
     public DbSet<CoLabType> CoLabTypes { get; set; } 
     public DbSet<Contact> Contacts { get; set; } 
     public DbSet<Document> Documents { get; set; } 
     public DbSet<Organization> Organizations { get; set; } 
     public DbSet<Participant> Participants { get; set; } 
     public DbSet<Project> Projects { get; set; } 
     public DbSet<Statement> Statements { get; set; } 
     public DbSet<TriggeringQuestion> TriggeringQuestions { get; set; } 
     public DbSet<VoteAction> VoteActions { get; set; } 
     public DbSet<Vote> Votes { get; set; } 
     public DbSet<VoteType> VoteTypes { get; set; } 
     public DbSet<AspNetUser> AspNetUser { get; set; } 
     public DbSet<AspNetRole> AspNetRole { get; set; } 

     protected override void OnModelCreating(DbModelBuilder modelBuilder) 
     { 
      modelBuilder.Configurations.Add(new ClusterMap()); 
      modelBuilder.Configurations.Add(new CoLabDateMap()); 
      modelBuilder.Configurations.Add(new CoLabLocationMap()); 
      modelBuilder.Configurations.Add(new CoLabMap()); 
      modelBuilder.Configurations.Add(new CoLabTypeMap()); 
      modelBuilder.Configurations.Add(new ContactMap()); 
      modelBuilder.Configurations.Add(new DocumentMap()); 
      modelBuilder.Configurations.Add(new OrganizationMap()); 
      modelBuilder.Configurations.Add(new ParticipantMap()); 
      modelBuilder.Configurations.Add(new ProjectMap()); 
      modelBuilder.Configurations.Add(new StatementMap()); 
      modelBuilder.Configurations.Add(new TriggeringQuestionMap()); 
      modelBuilder.Configurations.Add(new VoteActionMap()); 
      modelBuilder.Configurations.Add(new VoteMap()); 
      modelBuilder.Configurations.Add(new VoteTypeMap()); 
     } 
    } 

Answer 1

好了...想通了什麼是可能處理這個問題的上級方法。我創建名爲AspNetRoleMap.cs

public AspNetRoleMap() 
{ 
    // Primary Key 
    this.HasKey(t => t.Id); 

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

    // Relationships 
    this.HasMany(u => u.AspNetUsers) 
     .WithMany(t => t.AspNetRoles) 
     .Map(
      m => 
      { 
       m.MapLeftKey("RoleId"); 
       m.MapRightKey("UserId"); 
       m.ToTable("AspNetUserRoles"); 
      } 
     ); 

} 

然後在的DbContext OnModelCreating（）的映射文件I加入下面包含它。

modelBuilder.Configurations.Add(new AspNetRoleMap());
