我正在開發一個在線商店的web項目。目前,我試圖在網頁上顯示數據庫表格中的內容。使用asp.net mvc爲數據庫創建Web界面5
表看起來是這樣的:
這是型號:
using System;
using System.ComponentModel.DataAnnotations;
namespace Vidly.Models
{
public class Rental
{
public int Id { get; set; }
[Required]
public Customer Customer { get; set; }
[Required]
public Movie Movie { get; set; }
public DateTime DateRented { get; set; }
public DateTime? DateReturned { get; set; }
}
}
我創建了一個API控制器,它看起來像這樣
using AutoMapper;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using Vidly.Dtos;
using Vidly.Models;
using System.Data.Entity;
namespace Vidly.Controllers.Api
{
public class RentalsController : ApiController
{
private ApplicationDbContext _context;
public RentalsController()
{
_context = new ApplicationDbContext();
}
// GET /api/rentals
public IHttpActionResult GetRentals(string query = null)
{
var rentalsQuery = _context.Rentals
.Include(r => r.Customer)
.Include(r => r.Movie);
var rentalDtos = rentalsQuery
.ToList()
.Select(Mapper.Map<Rental, RentalDto>);
return Ok(rentalDtos);
}
// GET /api/rentals/1
public IHttpActionResult GetRental(int id)
{
var rental = _context.Rentals.SingleOrDefault(r => r.Id == id);
if (rental == null)
return NotFound();
return Ok(Mapper.Map<Rental, RentalDto>(rental));
}
}
}
,另一個控制器,看起來像這樣:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using Vidly.Models;
using System.Data.Entity;
using Vidly.ViewModels;
namespace Vidly.Controllers
{
public class RentalsController : Controller
{
private ApplicationDbContext _context;
[Authorize(Roles = RoleName.CanManageMovies)]
public ViewResult Index()
{
if (User.IsInRole(RoleName.CanManageMovies))
return View("Index");
else
return View("Home");
}
public ActionResult New()
{
return View();
}
public ActionResult Details(int id)
{
var rental = _context.Rentals.Include(r => r.Movie).Include(r => r.Customer).SingleOrDefault(r => r.Id == id);
if (rental == null)
return HttpNotFound();
return View(rental);
}
}
}
最後,CSHTML文件看起來是這樣的:
@model IEnumerable<Vidly.Models.Rental>
@{
ViewBag.Title = "Rentals";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<h2>Rentals</h2>
<table id="rentals" class="table table-bordered table-hover">
<thead>
<tr>
<th>Customer</th>
<th>Movie</th>
<th>Date Rented</th>
</tr>
</thead>
<tbody></tbody>
</table>
@section scripts
{
<script>
$(document).ready(function() {
var table = $("#rentals").DataTable({
ajax: {
url: "/api/rentals",
dataSrc: ""
},
columns: [
{
data: "customer.name"
},
{
data: "movie.name"
},
{
data: "daterented"
}
]
});
});
</script>
}
的問題是,每當我試圖訪問該網頁時,我收到此錯誤消息5次,在每個條目表:
數據表警告:表ID =出租 - 請求的未知參數 「daterented」爲行0,列2。有關此 錯誤的詳細信息,請參閱http://datatables.net/tn/4
表看起來是這樣的:
和XML文件(訪問https://localhost:44300/api/rentals可用時),從那裏對錶中的數據將被取回這個樣子的:
我會很很高興能幫助我解決這個問題! 非常感謝!
你能告訴我們什麼是從服務器的響應。您可以在網絡標籤 –
中檢查。這是一個鏈接到它的圖像。 https://ibb.co/nmFO2a – Adrian
那麼你正在調用這個方法:'/ api/rentals',但我看不到它。這應該是正確的方法:'GetRentals'? –
