EF 7映射EntityTypeConfiguration [英] EF 7 Mapping EntityTypeConfiguration

问题描述

在EF6我们通常能够用这种方式来配置实体

In EF6 we usually able to use this way to configure the Entity

public class AccountMap : EntityTypeConfiguration<Account>
{
    public AccountMap()
    {
        ToTable("Account");
        HasKey(a => a.Id);

        Property(a => a.Username).HasMaxLength(50);
        Property(a => a.Email).HasMaxLength(255);
        Property(a => a.Name).HasMaxLength(255);
    }
}

我们如何能够EF 7，做自当I类继承EntityTypeConfiguration是无法找到类。

推荐答案

在EF7，可以覆盖OnModelCreating对你实施的DbContext类。

In EF7, you override OnModelCreating on the DbContext class you're implementing.

protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        modelBuilder.Entity<Account>()
            .ForRelational(builder => builder.Table("Account"))
            .Property(value => value.Username).MaxLength(50)
            .Property(value => value.Email).MaxLength(255)
            .Property(value => value.Name).MaxLength(255);
    }
