Question

我有以下型号 -

public class RoleModel
{
    public int Id { get; set; }
    public string RoleName { get; set; }
    public string Description { get; set; }
    public DateTime DateCreated { get; set; }
    public int CreatedBy { get; set; }
    public DateTime LastUpdated { get; set; }
    public int LastUpdateBy { get; set; }

    [NotMapped]
    public State State { get; set; }

    public virtual IEnumerable<UserModel> Users { get; set; }
    public virtual IEnumerable<UserModel> UsersNotInRole { get; set; }
    public virtual int[] SelectedUsers { get; set; }

    public virtual List<RightModel> Rights { get; set; }
    public virtual List<RightModel> SelectedRights { get; set; }

    public RoleModel()
    {

    }
}

public class RightModel
{
    public string RightName { get; set; }
    public string Description { get; set; }
    public bool Assigned { get; set; }
}

由此，每个角色都分配了一组权限。从以下视图中，我希望允许用户针对要分配给所选角色的每个权限选中一个复选框。视图正在正确加载数据并检查正确的框，但是当我按“保存”时，权限列表为空。任何想法我如何纠正这一点，以便从所选角色中删除所有权利，然后重新分配所需的权利。

 @model Project.Core.Models.Roles.RoleModel
 @using (Html.BeginForm())
 {
      @Html.ValidationSummary(true)
      <div class="tab-pane" id="tab_1_3">
                                    <table class="table table-striped">
                                        <thead>
                                            <tr>
                                                <th>Right Name</th>
                                                <th>Description</th>
                                                <th></th>
                                            </tr>
                                        </thead>
                                        <tbody>
                                            @foreach (var right in Model.Rights)
                                            {
                                                <tr>
                                                    <td>@Html.DisplayFor(model => right.RightName)</td>
                                                    <td>@Html.DisplayFor(model => right.Description)</td>
                                                    <td>
                                                        <div class="success-toggle-button">
                                                            @Html.CheckBoxFor(model => right.Assigned, new { @class = "toggle" })
                                                        </div>
                                                    </td>
                                                </tr>
                                            }
                                        </tbody>
                                    </table>
                                </div>

和我的控制器 -

[Authorize]
    public ActionResult Details(int id = 0)
    {
        RoleModel role = _roleService.GetById(id);

        if (role == null)
        {
            return HttpNotFound();
        }
        return View(role);
    }

    [HttpPost]
    public ActionResult Details(RoleModel model)
    {
        if (ModelState.IsValid)
        {
            _roleService.Update(model);

            return RedirectToAction("Index");
        }

        return View(model);
    }

和RoleService中的Update方法 -

public void Update(RoleModel entity)
    {
        entity.LastUpdated = DateTime.Now;
        entity.LastUpdateBy = 1;

        Role r = _roleRepository.FindById(entity.Id);

        AutoMapper.Mapper.CreateMap<RoleModel, Role>();

        _roleRepository.Update(AutoMapper.Mapper.Map(entity, r));
    }

和我的存储库更新方法 -

 public void Update(Role role)
    {
        _context.ObjectStateManager.ChangeObjectState(role, EntityState.Modified);

        SaveChanges();
    }

正如user3153169在评论中所述，对于集合，您需要将您的元素的id / name设置为RoleModel.Rights [i]。为自动播放器找到元素。

所以你应该使用for循环

@for (int i = 0 ; i < Model.Rights.Count() ; i++)
{
    <tr>
        <td>@Html.DisplayFor(model => Model.Rights[i].RightName)</td>
        <td>@Html.DisplayFor(model => Model.Rights[i].Description)</td>
        <td>
            <div class="success-toggle-button">
                @Html.CheckBoxFor(model => Model.Rights[i].Assigned, new { @class = "toggle" })
            </div>
        </td>
    </tr>
}
