[英]Entity Framework Core 2.0 Add-Migration doesn't create any migration files
[英]Entity framework core doesn't create migration file
我已經完成了模型結構並運行了
sudo dotnet ef遷移添加3-MyMigration
命令,但在“遷移”文件夾中未創建文件。
這是輸出:

Finding DbContext classes...
Using context 'ApplicationDbContext'.
因此,不會顯示任何錯誤。
這是使用的上下文:
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
public DbSet<GenealogyRelation> GenealogyRelation { get; set; }
public DbSet<FalEvent> FalEvent { get; set; }
public DbSet<GenealogyFalEvent> GenealogyFalEvent { get; set; }
public DbSet<BaptemeFalEvent> BaptemeFalEvent { get; set; }
public DbSet<AdoptionFalEvent> AdoptionFalEvent { get; set; }
public DbSet<ConfirmationFalEvent> ConfirmationFalEvent { get; set; }
public DbSet<GenealogyCityAndFieldFalEvent> GenealogyCityAndFieldFalEvent { get; set; }
public DbSet<City> City { get; set; }
public DbSet<FalProfile> FalProfile { get; set; }
public DbSet<SocialProfile> SocialProfile { get; set; }
public DbSet<StudyField> StudyField { get; set; }
public DbSet<UserStudyField> UserStudyField { get; set; }
public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
: base(options)
{
}
protected override void OnModelCreating(ModelBuilder builder)
{
builder.Entity<GenealogyFalEvent>().ToTable("GenealogyFalEvent");
builder.Entity<BaptemeFalEvent>().ToTable("BaptemeFalEvent");
builder.Entity<ConfirmationFalEvent>().ToTable("ConfirmationFalEvent");
builder.Entity<AdoptionFalEvent>().ToTable("AdoptionFalEvent");
base.OnModelCreating(builder);
// Customize the ASP.NET Identity model and override the defaults if needed.
// For example, you can rename the ASP.NET Identity table names and more.
// Add your customizations after calling base.OnModelCreating(builder);
builder.Entity<GenealogyRelation>().HasKey((e) => new {e.ChildID, e.GenealogyFalEventID, e.ParentID});
builder.Entity<UserCity>().HasKey(u => new {u.CityID, u.UserID});
builder.Entity<UserStudyField>().HasKey(u => new {u.StudyFieldID, u.UserID});
}
}
EF Core為什么不創建遷移文件?
您的模型真的需要遷移嗎? 如果自從上次遷移以來未進行修改,則ef可能不需要生成遷移。
只是不確定而已。
