Question

我在尝试更新数据库时遇到问题。我正在使用asp.net制作web-api。

我刚刚添加了新的迁移功能并且运行良好。然后使用update-database命令更新我的数据库。然后我改变了一些代码。当我添加新的迁移时，它说：

Unable to generate an explicit migration because the following explicit migrations are pending: 
[201705310248355_changeProduct, 201706191007322_ModifyModel, 201707170631209_changeProductModel, 201707170652556_EditProductModelLagi, 201707180312064_AddStorageIdOnInventory, 201707190243206_ChangeRepository, 201708091124374_EditInventory, 201803130702299_testBoom]. 

Apply the pending explicit migrations before attempting to generate a new explicit migration.

但上次更新数据库时，它完美运行

PM> update-database -target testboom -startupprojectname ShopDiaryProject.EF -force
Specify the '-Verbose' flag to view the SQL statements being applied to the target database.
Target database is already at version 201803130702299_testBoom.

Soo，我尝试使用-force参数添加迁移。它有效！

，但

我再次更新数据库，迁移内容喜欢从头开始，不能添加表。以下是我的迁移：

 public override void Up()
    {
        CreateTable(
            "dbo.Categories",
            c => new
                {
                    Id = c.Guid(nullable: false),
                    Name = c.String(maxLength: 200),
                    Description = c.String(maxLength: 200),
                    UserId = c.Guid(nullable: false),
                    CreatedDate = c.DateTime(nullable: false),
                    ModifiedDate = c.DateTime(),
                    DeletedDate = c.DateTime(),
                    CreatedUserId = c.String(),
                    ModifiedUserId = c.String(),
                    DeletedUserID = c.String(),
                    IsDeleted = c.Boolean(nullable: false),
                    User_Id = c.String(maxLength: 128),
                })
            .PrimaryKey(t => t.Id)
            .ForeignKey("dbo.AspNetUsers", t => t.User_Id)
            .Index(t => t.User_Id);

        CreateTable(
            "dbo.Products",
            c => new
                {
                    Id = c.Guid(nullable: false),
                    Name = c.String(maxLength: 250),
                    BarcodeId = c.String(maxLength: 250),
                    CategoryId = c.Guid(nullable: false),
                    CreatedDate = c.DateTime(nullable: false),
                    ModifiedDate = c.DateTime(),
                    DeletedDate = c.DateTime(),
                    CreatedUserId = c.String(),
                    ModifiedUserId = c.String(),
                    DeletedUserID = c.String(),
                    IsDeleted = c.Boolean(nullable: false),
                })
            .PrimaryKey(t => t.Id)
            .ForeignKey("dbo.Categories", t => t.CategoryId, cascadeDelete: true)
            .Index(t => t.CategoryId);

        CreateTable(
            "dbo.Shopitems",
            c => new
                {
                    Id = c.Guid(nullable: false),
                    Quantity = c.Int(nullable: false),
                    price = c.Decimal(nullable: false, precision: 18, scale: 2),
                    ProductId = c.Guid(nullable: false),
                    ShoplistId = c.Guid(nullable: false),
                    CreatedDate = c.DateTime(nullable: false),
                    ModifiedDate = c.DateTime(),
                    DeletedDate = c.DateTime(),
                    CreatedUserId = c.String(),
                    ModifiedUserId = c.String(),
                    DeletedUserID = c.String(),
                    IsDeleted = c.Boolean(nullable: false),
                })

并且它说数据库中已经有一个名为“Categories”的对象。有什么想法吗？
