Asp.Net 核心和支架

Asp.Net Core and Scaffold

生成自动脚手架到Asp.Net Razor 页面是否兼容 bool 数据类型?

我问一下,因为我正在学习这个教程:https://docs.microsoft.com/en-us/aspnet/core/tutorials/razor-pages/model。在创建 POCO class、配置 dbContext 和迁移之后,我 运行 此命令自动生成脚手架

dotnet aspnet-codegenerator razorpage -m Movie -dc MovieContext -udl -outDir Pages\Movies --referenceScriptLibraries

它很漂亮,但如果我的 POCO class 没有 bool 类型,它就可以工作。

示例 POCO class:

using System;

namespace RazorPagesMovie.Models
{
    public class Movie
    {
        public int ID { get; set; }
        public string Title { get; set; }
        public DateTime ReleaseDate { get; set; }
        public string Genre { get; set; }
        public bool Active { get; set; }
    }
}

通过这个实现,我会在尝试创建电影时得到这个错误:

'CreateModel' does not contain a definition for 'Active' and no extension method 'Active' accepting a first argument of type 'CreateModel' could be found (are you missing a using directive or an assembly reference?)

有什么想法吗?

也许是我使用 SQLite 作为数据库的必要信息...

和 CreateModel class:

using System;    
using System.Collections.Generic;    
using System.Linq;    
using System.Threading.Tasks;    
using Microsoft.AspNetCore.Mvc;    
using Microsoft.AspNetCore.Mvc.RazorPages;    
using Microsoft.AspNetCore.Mvc.Rendering;    
using RazorPagesMovie.Models;

namespace RazorPagesMovie.Pages.Movies    
{    
    public class CreateModel : PageModel    
    {    
        private readonly RazorPagesMovie.Models.MovieContext _context;    

        public CreateModel(RazorPagesMovie.Models.MovieContext context)    
        {    
            _context = context;    
        }        

        public IActionResult OnGet()    
        {    
            Movie = new Movie    
            {    
                Title = "The Good, the bad, and the ugly",    
                Genre = "Western",    
                Price = 1.19M,    
                ReleaseDate = DateTime.Now,    
                Active = true    
            };    
            return Page();    
        }        

        [BindProperty]    
        public Movie Movie { get; set; }    

        public async Task<IActionResult> OnPostAsync()    
        {    
            if (!ModelState.IsValid)    
            {    
                return Page();    
            }    

            _context.Movie.Add(Movie);    
            await _context.SaveChangesAsync();    

            return RedirectToPage("./Index");    
        }    
    }    
}

这一行有问题:

@Html.DisplayNameFor(model => model.Active))

Create.cshtml 中,在使用 this 的地方,model 指的是 CreateModel 而不是 Movie。相反,您需要:

@Html.DisplayNameFor(model => model.Movie.Active))

我在 ASP.NET Core GitHub 网站上提出了这个错误,它已在 .NET Core 2.0 中修复: https://github.com/aspnet/Scaffolding/issues/830

但是看起来修复程序并没有移植到 2.1,所以我在这里提出了一个新错误: https://github.com/aspnet/Scaffolding/issues/855
