[ASP.net教程]MVC5 网站开发之七 用户功能 2 .1用户资料的修改和删除


这次主要实现管理后台界面用户资料的修改和删除,修改用户资料和角色是经常用到的功能,但删除用户的情况比较少,为了功能的完整性还是坐上了。主要用到两个action “Modify”和“Delete”。

一、用户资料修改(Modify)

此功能分两个部分:

public ActionResult Modify(int id) 用于显示用户信息

[httppost]

public ActionResult Modify(FormCollection form)用户就收前台传来的信息并修改

1、显示用户信息

/// <summary>    /// 修改用户信息    /// </summary>    /// <param name="id">用户主键</param>    /// <returns>分部视图</returns>    public ActionResult Modify(int id)    {      //角色列表      var _roles = new RoleManager().FindList();      List<SelectListItem> _listItems = new List<SelectListItem>(_roles.Count());      foreach (var _role in _roles)      {        _listItems.Add(new SelectListItem() { Text = _role.Name, Value = _role.RoleID.ToString() });      }      ViewBag.Roles = _listItems;      //角色列表结束      return PartialView(userManager.Find(id));    }

此action有一个参数id,接收传入的用户ID,在action中查询角色信息,并利用viewBage传递到视图,并通过return PartialView(userManager.Find(id))向视图传递用户模型返回分部视图。

视图代码如下:

@model Ninesky.Core.User@using (Html.BeginForm()){  @Html.AntiForgeryToken()  <div class="form-horizontal">    @Html.ValidationSummary(true, "", new { @class = "text-danger" })    @Html.HiddenFor(model => model.UserID)    <div class="form-group">      @Html.LabelFor(model => model.RoleID, htmlAttributes: new { @class = "control-label col-md-2" })      <div class="col-md-10">        @Html.DropDownListFor(model => model.RoleID, (IEnumerable<SelectListItem>)ViewBag.Roles, new { @class = "form-control" })        @Html.ValidationMessageFor(model => model.RoleID, "", new { @class = "text-danger" })      </div>    </div>    <div class="form-group">      @Html.LabelFor(model => model.Username, htmlAttributes: new { @class = "control-label col-md-2" })      <div class="col-md-10">        @Html.EditorFor(model => model.Username, new { htmlAttributes = new { @class = "form-control", disabled = "disabled" } })        @Html.ValidationMessageFor(model => model.Username, "", new { @class = "text-danger" })      </div>    </div>    <div class="form-group">      @Html.LabelFor(model => model.Name, htmlAttributes: new { @class = "control-label col-md-2" })      <div class="col-md-10">        @Html.EditorFor(model => model.Name, new { htmlAttributes = new { @class = "form-control" } })        @Html.ValidationMessageFor(model => model.Name, "", new { @class = "text-danger" })      </div>    </div>    <div class="form-group">      @Html.LabelFor(model => model.Sex, htmlAttributes: new { @class = "control-label col-md-2" })      <div class="col-md-10">        @Html.RadioButtonFor(model => model.Sex, 1) 男        @Html.RadioButtonFor(model => model.Sex, 0) 女        @Html.RadioButtonFor(model => model.Sex, 2) 保密        @Html.ValidationMessageFor(model => model.Sex, "", new { @class = "text-danger" })      </div>    </div>    <div class="form-group">      @Html.LabelFor(model => model.Password, htmlAttributes: new { @class = "control-label col-md-2" })      <div class="col-md-10">        @Html.EditorFor(model => model.Password, new { htmlAttributes = new { @class = "form-control" } })        @Html.ValidationMessageFor(model => model.Password, "", new { @class = "text-danger" })      </div>    </div>    <div class="form-group">      @Html.LabelFor(model => model.Email, htmlAttributes: new { @class = "control-label col-md-2" })      <div class="col-md-10">        @Html.EditorFor(model => model.Email, new { htmlAttributes = new { @class = "form-control" } })        @Html.ValidationMessageFor(model => model.Email, "", new { @class = "text-danger" })      </div>    </div>    <div class="form-group">      @Html.LabelFor(model => model.LastLoginTime, htmlAttributes: new { @class = "control-label col-md-2" })      <div class="col-md-10">        @Html.EditorFor(model => model.LastLoginTime, new { htmlAttributes = new { @class = "form-control", disabled = "disabled" } })        @Html.ValidationMessageFor(model => model.LastLoginTime, "", new { @class = "text-danger" })      </div>    </div>    <div class="form-group">      @Html.LabelFor(model => model.LastLoginIP, htmlAttributes: new { @class = "control-label col-md-2" })      <div class="col-md-10">        @Html.EditorFor(model => model.LastLoginIP, new { htmlAttributes = new { @class = "form-control", disabled = "disabled" } })        @Html.ValidationMessageFor(model => model.LastLoginIP, "", new { @class = "text-danger" })      </div>    </div>    <div class="form-group">      @Html.LabelFor(model => model.RegTime, htmlAttributes: new { @class = "control-label col-md-2" })      <div class="col-md-10">        @Html.EditorFor(model => model.RegTime, new { htmlAttributes = new { @class = "form-control", disabled = "disabled" } })        @Html.ValidationMessageFor(model => model.RegTime, "", new { @class = "text-danger" })      </div>    </div>  </div>}

2、修改用户资料的后台处理

[HttpPost]    [ValidateAntiForgeryToken]    public ActionResult Modify(int id,FormCollection form)    {      Response _resp = new Auxiliary.Response();      var _user = userManager.Find(id);      if (TryUpdateModel(_user, new string[] { "RoleID", "Name", "Sex", "Email" }))      {        if (_user == null)        {          _resp.Code = 0;          _resp.Message = "用户不存在,可能已被删除,请刷新后重试";        }        else        {          if (_user.Password != form["Password"].ToString()) _user.Password = Security.SHA256(form["Password"].ToString());          _resp = userManager.Update(_user);        }      }      else      {        _resp.Code = 0;        _resp.Message = General.GetModelErrorString(ModelState);      }      return Json(_resp);    }

此方法有两个参数id 和FormCollection form,不用User直接做模型的原因是因为user会把前台所有数据都接收过来,这里我并不想允许修改用户名,所以在方法中使用TryUpdateModel绑定允许用户修改的属性。TryUpdateModel在绑定失败时同样会在在ModelState中记录错误,可以利用自定义方法GetModelErrorString获取到错误信息并反馈给视图。

2、前台显示和处理

打开Index视图找到表格初始化方法,格式化列“Username”使其显示一个连接,代码红线部分。

使其看起来这个样子,当用户点击连接的时候可以显示修改对话框

image

弹出窗口和发送到服务器的js代码写到表格的onLoadSuccess方法里

onLoadSuccess: function () {          //修改          $("a[data-method='Modify']").click(function () {            var id = $(this).attr("data-value");            var modifyDialog = new BootstrapDialog({              title: "<span class='glyphicon glyphicon-user'></span>修改用户",              message: function (dialog) {                var $message = $('<div></div>');                var pageToLoad = dialog.getData('pageToLoad');                $message.load(pageToLoad);                return $message;              },              data: {                'pageToLoad': '@Url.Action("Modify")/' + id              },              buttons: [{                icon: "glyphicon glyphicon-plus",                label: "保存",                action: function (dialogItself) {                  $.post($("form").attr("action"), $("form").serializeArray(), function (data) {                    if (data.Code == 1) {                      BootstrapDialog.show({                        message: data.Message,                        buttons: [{                          icon: "glyphicon glyphicon-ok",                          label: "确定",                          action: function (dialogItself) {                            $table.bootstrapTable("refresh");                            dialogItself.close();                            modifyDialog.close();                          }                        }]                      });                    }                    else BootstrapDialog.alert(data.Message);                  }, "json");                  $("form").validate();                }              }, {                icon: "glyphicon glyphicon-remove",                label: "关闭",                action: function (dialogItself) {                  dialogItself.close();                }              }]            });            modifyDialog.open();          });          //修改结束}

显示效果如下图

二、删除用户

UserController中添加删除方法

/// <summary>    /// 删除    /// </summary>    /// <param name="id">用户ID</param>    /// <returns></returns>    [HttpPost]    public ActionResult Delete(int id)    {      return Json(userManager.Delete(id));    }

 

打开Index视图找到表格初始化方法,添加“操作”列格式化列使其显示一个删除按钮,代码红框部分。

然后在表格的onLoadSuccess方法里刚写的修改用户信息的js代码后面写删除用户的js代码

//修改结束          //删除按钮          $("a[data-method='Delete']").click(function () {            var id = $(this).attr("data-value");            BootstrapDialog.confirm("你确定要删除" + $(this).parent().parent().find("td").eq(3).text() + "吗?\n 建议尽可能不要删除用户。", function (result) {              if (result) {                $.post("@Url.Action("Delete", "User")", { id: id }, function (data) {                  if (data.Code == 1) {                    BootstrapDialog.show({                      message: "删除用户成功",                      buttons: [{                        icon: "glyphicon glyphicon-ok",                        label: "确定",                        action: function (dialogItself) {                          $table.bootstrapTable("refresh");                          dialogItself.close();                        }                      }]                    });                  }                  else BootstrapDialog.alert(data.Message);                }, "json");              }            });          });          //删除按钮结束        }      });      //表格结束

前台显示效果
