替代多對多關係的代碼優先命名約定

Question

我有兩個實體，其中多對多關係不遵循代碼優先的命名約定，我必須找到一種方法來覆蓋該關係。

第一實體：

public class User 
{ 
    public int UserId { get; set; } 
    public string Username { get; set; } 
    public virtual ICollection<Rule> { get; set; } 
} 

第二實體：

public class Rule 
{ 
    public int RuleId { get; set; } 
    public string Description { get; set; } 
    public virtual ICollection<User> { get; set; } 
} 

我有一個表中的那些2與經典的映射（名稱是UserRule具有由2個colums複合主鍵的間（UserId, RuleId）與對應的外鍵）

我使用的dbcontext是這一個：

public class DataContext : DbContext 
{ 
    public IDbSet<User> Users { get; private set; } 
    public IDbSet<Rule> Rules { get; private set; } 

    private const string ConnectionStringName = "connectionstring"; 

    public DataContext() : base(ConnectionStringName) 
    { 
     Configuration.LazyLoadingEnabled = true; 

     Rules = Set<Rule>(); 
     Users = Set<User>(); 
    } 

    protected override void OnModelCreating(DbModelBuilder builder) 
    { 
     // use this to disable database migrations and not use metadata inside database 
     Database.SetInitializer<DataContext>(null); 

     // setup MaestroAgentConfig to its table 
     builder.Configurations.Add(new UserTable()); 

     // setup SecurityRule to its table 
     builder.Configurations.Add(new RuleTable()); 

     base.OnModelCreating(builder); 
    } 

    public override int SaveChanges() 
    { 
     return base.SaveChanges(); 
    } 
} 

的映射表，我已經是：

public class UserTable : EntityTypeConfiguration<User> 
{ 
    public UserProfileTable() 
    { 
     Property(x => x.UserId).HasColumnName("UserId").HasDatabaseGeneratedOption(DatabaseGeneratedOption.Identity); 
     HasMany(x => x.SecurityRules) 
      .WithMany(x => x.UserProfiles) 
      .Map(map => 
      { 
       map.MapRightKey("UserId"); 
       map.MapRightKey("RuleId"); 
       map.ToTable("UserRule"); 
      }); 
     ToTable("User"); 
    } 
} 

和：

public class RuleTable : EntityTypeConfiguration<Rule> 
{ 
    public RuleTable() 
    { 
     Property(x => x.RuleId).HasColumnName("RuleId").HasDatabaseGeneratedOption(DatabaseGeneratedOption.Identity); 
     HasKey(x => x.RuleId); 
     ToTable("Rule"); 
    } 
} 

然而，當EF查詢數據庫，它看起來像這樣：

exec sp_executesql N' 
SELECT TOP (1) 
    [Extent1].[UserId] AS [UserId], 
    { other fields } 
FROM 
    [dbo].[UserProfile] AS [Extent1] 
WHERE 
    [Extent1].[UserName] = @p__linq__0',N'@p__linq__0 nvarchar(4000)',@p__linq__0=N'EMYODE\erick.girard' 

和：

exec sp_executesql N' 
SELECT 
    [Extent2].[RuleId] AS [RuleId], 
    [Extent2].[Description] AS [Description] 
FROM 
    [dbo].[UserRule] AS [Extent1] 
INNER JOIN 
    [dbo].[Rule] AS [Extent2] ON [Extent1].[RuleId] = [Extent2].[RuleId] 
WHERE 
    [Extent1].[User_UserId] = @EntityKeyValue1',N'@EntityKeyValue1 int',@EntityKeyValue1=37 

現在2號的要求，我不能找到一種方法，使用「UserId」僅在UserRule表

我如何能做到這一點？

（編輯） 我試着刪除以下3個約定，但到目前爲止，沒有任何改變：

builder.Conventions.Remove<PluralizingEntitySetNameConvention>(); 
builder.Conventions.Remove<NavigationPropertyNameForeignKeyDiscoveryConvention>(); 
builder.Conventions.Remove<TypeNameForeignKeyDiscoveryConvention>(); 

Answer 1

是您的代碼的精確副本，或僞代碼？

粘貼在你的代碼完全是，我得到了相同的結果 -

但是，你映射的映射表的右側部分兩次：

map.MapRightKey("UserId"); 
map.MapRightKey("RuleId"); 

我改變了top命令映射到左鍵

map.MapLeftKey("UserId"); 
map.MapRightKey("RuleId"); 

併爲我修好了。
