记开发个人图书收藏清单小程序开发（七）DB设计

前面的书房初始化的前端信息已经完善，所以现在开始实现DB的Script部分。

新增Action:Shelf_Init.sql

svc.sql

 CREATE SCHEMA [svc]
     AUTHORIZATION [dbo];

Shelf_Init.sql

 CREATE PROCEDURE [svc].[Shelf$Init](@json nvarchar(max))
 WITH ENCRYPTION
 AS
 BEGIN
     SET    NOCOUNT    ON;
     SET XACT_ABORT ON;
     BEGIN TRY
         BEGIN    TRAN;

         declare    @nickName nvarchar(20), @shelfName nvarchar(20);
         select    @nickName=NickName,     @shelfName=ShelfName
         from    openjson (@json, '$')
         with (
             NickName        nvarchar(20),
             ShelfName        nvarchar(20)
         );

         insert    core._Party(Type, Alias) select k._User, @nickName
         from    core.Party#Type() k;
         declare    @userID int=@@identity;

         insert    core._Party(PID, Type, Alias) select @userID, k._Shelf, @shelfName
         from    core.Party#Type() k;

         COMMIT    TRAN;
     END TRY
     BEGIN CATCH
         if (xact_state() = -1) ROLLBACK TRAN; throw;
     END CATCH
 END

好了，我去试试前端能不能初始化信息进DB

....

在测试之前，我们需要实现一下Init Razor Pages代码：

Init.cshtml.cs

     using M = Shelf;
     public class InitModel : PageModel
     {
         private readonly IShelfRepo _shelfRepo;
         public InitModel(IShelfRepo shelfRepo)
         {
             _shelfRepo = shelfRepo;
         }
         [BindProperty]
         public InitInputModel Input { get; set; }

         public void OnGet()
         {

         }

         public async Task<IActionResult> OnPostAsync()
         {
             if (ModelState.IsValid)
             {
                 await _shelfRepo.InitAsync(new M.InitSpec
                 {
                     NickName = Input.NickName.Trim(),
                     ShelfName = Input.ShelfName.Trim()
                 });
                 return RedirectToPage("New");
             }
             return Page();
         }
     }

页面内容也需要修改一下form部分

Init.cshtml

 <form method="post">
     <div class="form-group form-group-lg">
         <label asp-for="Input.NickName"></label>
         <input class="form-control form-control-lg" asp-for="Input.NickName" autocomplete="off">
         <span asp-validation-for="Input.NickName" class="text-danger"></span>
     </div>
     <div class="form-group form-group-lg">
         <label asp-for="Input.ShelfName"></label>
         <input class="form-control form-control-lg" asp-for="Input.ShelfName" autocomplete="off">
         <span asp-validation-for="Input.ShelfName" class="text-danger"></span>
     </div>
     <div class="form-group text-right">
         <button class="btn btn-warning btn-lg" type="submit">Save</button>
     </div>
 </form>

填写不动书房的信息：

点击Save按钮提交，OK，正常提交了并跳转了。

查看下DB有没有数据：

哈哈，看来一切正常。
