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
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。
前台显示效果
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
