Code First EF缺少表格

Question

我开发了一个代码优先的应用程序，我遇到了很多问题。我有一个已定义的类，用于绘制表格＆＃39; PatientChart＆＃39; 它看起来像：

public class PatientChart
{
    [Key]
    public int PatientChartId { get; set; }
    [MaxLength(2048)]
    public string Allergies { get; set; }
    [MaxLength(2048)]
    public string PrimaryAilments { get; set; }
    [MaxLength(2048)]
    public string Sensitivities { get; set; }
    [MaxLength(2048)]
    public string Medications { get; set; }
    [MaxLength(512)]
    public string ReferredBy { get; set; }
    public string ChartNotes { get; set; }
    [MaxLength(2048)]
    public string MedicalHistory { get; set; }
    [MaxLength(2048)]
    public string SocialHistory { get; set; }
    [MaxLength(128)]
    public string PatientInfo_Id1 { get; set; }
    public virtual AspNetUser PatientInfo { get; set; }
}

我在映射ForeignKey列（PatientInfo_Id）时遇到了很多困难。出于某种原因，EntityFramework继续将它映射到像PatientInfo_Id1，Id2等奇怪的东西。所以我愚蠢地从Sql Management Studio中删除了整个表。

对于我的生活，我无法获得update-database来重新生成表PatientChart。我也清除了__MigrationHistory表！做不好的决定。

我应该删除整个数据库并重新开始吗？

这是我的DbContext：

public partial class HMSModel : DbContext
    {
        public HMSModel()
            : base("name=HMSModel")
        {
        }

        public virtual DbSet<C__MigrationHistory> C__MigrationHistory { get; set; }
        public virtual DbSet<AspNetRole> AspNetRoles { get; set; }
        public virtual DbSet<AspNetUserClaim> AspNetUserClaims { get; set; }
        public virtual DbSet<AspNetUserLogin> AspNetUserLogins { get; set; }
        public virtual DbSet<AspNetUserRole> AspNetUserRoles { get; set; }
        public virtual DbSet<AspNetUser> AspNetUsers { get; set; }
        public virtual DbSet<ActiveSession> ActiveSessions { get; set; }
        public virtual DbSet<PatientChart> PatientCharts { get; set; }
        public virtual DbSet<PatientCert> PatientCert { get; set; }
        public virtual DbSet<PatientImages> PatientImages { get; set; }
        public virtual DbSet<Appointment> Appointment { get; set; }
        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            modelBuilder.Entity<AspNetUser>()
                .HasMany(e => e.AspNetUserClaims)
                .WithRequired(e => e.AspNetUser)
                .HasForeignKey(e => e.UserId);

            modelBuilder.Entity<AspNetUser>()
                .HasMany(e => e.AspNetUserLogins)
                .WithRequired(e => e.AspNetUser)
                .HasForeignKey(e => e.UserId);

            modelBuilder.Entity<AspNetUser>()
                .HasMany(e => e.AspNetUserRoles)
                .WithRequired(e => e.AspNetUser)
                .HasForeignKey(e => e.UserId);



        }
    }

我试过了： Reset Entity-Framework Migrations Entity Framework Code First - two Foreign Keys from same table 加上一百万个其他没有运气的链接。我希望有人聪明，可以帮助我。

该Chart类应该以1：1的比例绑定到AspNetUser

 public partial class AspNetUser
    {
        [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2214:DoNotCallOverridableMethodsInConstructors")]
        public AspNetUser()
        {
            AspNetUserClaims = new HashSet<AspNetUserClaim>();
            AspNetUserLogins = new HashSet<AspNetUserLogin>();
            AspNetUserRoles = new HashSet<AspNetUserRole>();
        }

        public string Id { get; set; }

        [StringLength(256)]
        public string Email { get; set; }

        public bool EmailConfirmed { get; set; }

        public string PasswordHash { get; set; }

        public string SecurityStamp { get; set; }

        public string PhoneNumber { get; set; }

        public bool PhoneNumberConfirmed { get; set; }

        public bool TwoFactorEnabled { get; set; }

        public DateTime? LockoutEndDateUtc { get; set; }

        public bool LockoutEnabled { get; set; }

        public int AccessFailedCount { get; set; }
        [StringLength(256)]
        public string FirstName { get; set; }
        [StringLength(256)]
        public string LastName { get; set; }
        public string FullName { get { return string.Format("{0} {1}", FirstName, LastName); } }

        public string DOB { get; set; }

        public string Address1 { get; set; }
        [StringLength(256)]
        public string City { get; set; }
        [StringLength(2)]
        public string State { get; set; }
        [StringLength(25)]
        public string Zip { get; set; }

        public string Phone { get; set; }
        [StringLength(25)]
        public string Gender { get; set; }
        public bool? ReceiveSMS { get; set; }
        [Required]
        [StringLength(256)]
        public string UserName { get; set; }

        public DateTime? LastLogin { get; set; }
        public DateTime? RegisterDate { get; set; }
        public bool? Active { get; set; }
        [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")]
        public virtual ICollection<AspNetUserClaim> AspNetUserClaims { get; set; }

        [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")]
        public virtual ICollection<AspNetUserLogin> AspNetUserLogins { get; set; }

        [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")]
        public virtual ICollection<AspNetUserRole> AspNetUserRoles { get; set; }

        public virtual AspNetUserRole AspNetUserRole { get; set; }
        public virtual PatientCert PatientCert { get; set; }
        //public virtual PatientChart PatientChart { get; set; }
        public virtual ICollection<PatientImages> PatientImages { get; set; }

       // public virtual PatientChart PatientChart { get; set; }
        public virtual ICollection<Appointment> Appointment { get; set; }
    }

对于大多数大型应用程序，我总是首先使用数据库，这次我去了Code First。我觉得Code First是一种痛苦，充满了问题，但也许只是因为我缺乏知识深度。
