ASP.NET MVC5网站开发之用户资料的修改和删除3（七）

2016-11-27 17:34:23　 ASP.NET MVC5 网站用户

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-l abelFor(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-l abelFor(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-l abelFor(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-l abelFor(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-l abelFor(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-l abelFor(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-l abelFor(model => model-l astLoginTime, htmlAttributes: new { @class = "control-label col-md-2" }) <div class="col-md-10"> @Html.EditorFor(model => model-l astLoginTime, new { htmlAttributes = new { @class = "form-control", disabled = "disabled" } }) @Html.ValidationMessageFor(model => model-l astLoginTime, "", new { @class = "text-danger" }) </div> </div> <div class="form-group"> @Html-l abelFor(model => model-l astLoginIP, htmlAttributes: new { @class = "control-label col-md-2" }) <div class="col-md-10"> @Html.EditorFor(model => model-l astLoginIP, new { htmlAttributes = new { @class = "form-control", disabled = "disabled" } }) @Html.ValidationMessageFor(model => model-l astLoginIP, "", new { @class = "text-danger" }) </div> </div> <div class="form-group"> @Html-l abelFor(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。
