Asp.Net Razor Page 的自动脚手架生成是否兼容 bool 数据类型?
我问这个问题,因为我正在学习本教程:https://learn.microsoft.com/en-us/aspnet/core/tutorials/razor-pages/model .在创建 POCO 类、配置 dbContext 和迁移之后,我运行了这个命令来自动生成脚手架
dotnet aspnet-codegenerator razorpage -m Movie -dc MovieContext -udl -outDir Pages\Movies --referenceScriptLibraries
它很漂亮,但如果我的 POCO 类没有 bool 类型,它就可以工作。
示例 POCO 类:
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,当尝试创建电影时,我会得到这个错误:
'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 类:
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");
}
}
}
最佳答案
问题出在这一行:
@Html.DisplayNameFor(model => model.Active))
在 Create.cshtml
中,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))
