【问题描述】:
我正在尝试在自学的同时构建一个项目,但一直卡在一个地方。
我有这门课Roles:
namespace IC2021.Models
{
public partial class Roles
{
public Roles()
{
Staffs = new HashSet<Staffs>();
}
public int Id { get; set; }
public string Name { get; set; }
public virtual ICollection<Staffs> Staffs { get; set; }
}
}
还有一个叫Staffs:
namespace IC2021.Models
{
public partial class Staffs
{
public int Id { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Location { get; set; }
public int? RoleId { get; set; }
public string Archived { get; set; }
public virtual Roles Role { get; set; }
}
}
这是我的RolesController:
namespace IC2021.Controllers
{
public class RolesController : Controller
{
private readonly ICOctober2021Context _context;
public RolesController(ICOctober2021Context context)
{
_context = context;
}
// GET: Roles
public async Task<IActionResult> Index()
{
return View(await _context.Roles.ToListAsync());
}
public async Task<IActionResult> RolesWithStaffs()
{
var iCOctober2021Context = _context.Roles.Include(s => s.Staffs);
return View(await iCOctober2021Context.ToListAsync());
}
}
}
最后我尝试从RolesWithStaffs查看它:
<!-- model declaration -->
@model IEnumerable<IC2021.Models.Roles>
@{
ViewData["Title"] = "RolesWithViewController";
}
<h1>RolesWithViewController</h1>
<p>
<a asp-action="Create">Create New</a>
</p>
<table class="table">
<thead>
<tr>
<th>
Role
</th>
<th>
Staff Name
</th>
<th>
<th></th>
</tr>
</thead>
<tbody>
@foreach (var item in Model)
{
<tr>
<td>
@Html.DisplayFor(modelItem => item.Id)
</td>
<td>
@Html.DisplayFor(modelItem => item.Staffs)
</td>
@*<td>
<a asp-action="Edit" asp-route-id="@item.Id">Edit</a> |
<a asp-action="Details" asp-route-id="@item.Id">Details</a> |
<a asp-action="Delete" asp-route-id="@item.Id">Delete</a>
</td>*@
</tr>
}
</tbody>
</table>
因此,当我尝试从Staffs 访问时,我无法访问(例如item.Staffs.FirstName,或来自Staffs 的任何其他内容)。而我可以通过其他方式做到这一点,我的意思是从员工的角度来看,我可以访问 Roles.Name 或 Id)。
谁能帮帮我?任何帮助将不胜感激。

有什么问题?错误?预期的输入/输出?
