序
一、用户
二、用户组
三、栏目
3.1添加栏目
3.2浏览栏目
3.3更新栏目
上次在树形列表里面点击栏目名称后跳转到详细信息页面~/Category/ManageDetails/id。在详细页面里点修改，来完成栏目资料修改。
先打开【CategoryController】添加[ManageDetails(int id)]action
/// <summary>
/// 栏目详细资料
/// </summary>
/// <param name="id"></param>
/// <returns></returns>
public ActionResult ManageDetails(int id)
{
categoryRsy = new CategoryRepository();
var _node = categoryRsy.Find(id);
if (_node == null)
{
Error _e = new Error { Title = "栏目不存在", Details = "栏目不存在", Cause = Server.UrlEncode("<li>栏目已经删除</li>"), Solution = Server.UrlEncode("<li>返回<a href='" + Url.Action("Manage", "Cayegory") + "'>栏目栏目管理</a></li>") };
return RedirectToAction("ManageError", "Prompt", _e);
}
ModuleRepository _moduleRsy = new ModuleRepository();
var _modules = _moduleRsy.List(true);
List<SelectListItem> _slimodule = new List<SelectListItem>(_modules.Count());
foreach (Module _module in _modules)
{
if (_node.Model == _module.Model) _slimodule.Add(new SelectListItem { Text = _module.Name, Value = _module.Model, Selected = true });
else _slimodule.Add(new SelectListItem { Text = _module.Name, Value = _module.Model });
}
ViewData.Add("Model", _slimodule);
var _type = TypeSelectList;
_type.SingleOrDefault(t => t.Value == _node.Type.ToString()).Selected = true;
ViewData.Add("Type", _type);
return View(_node);
}
代码先是看栏目是否存在，不存在跳转到错误页面，后面是添加"Model“和“Type”的ViewData
右键添加强类型视图ManageDetails.cshtml,内容基本与ManageAdd.cshtml类似
@model Ninesky.Models.Category
@{
ViewBag.Title = "栏目信息";
Layout = "~/Views/Layout/_Manage.cshtml";
}
<div class="workspace">
<div class="inside">
<div class="notebar">

@using (Html.BeginForm("ManageUpdate","Category"))

$("#li_nav").show();
}
}
</script>
@section Scripts {
@Styles.Render("~/EasyUi/icon")
@Scripts.Render("~/bundles/EasyUi")
@Scripts.Render("~/bundles/jqueryval")
}
注意的是 @using (Html.BeginForm("ManageUpdate","Category"))这句；表示点修改按钮的后是向ManageUpdate提交数据。下面开始做这个action
在【CategoryController】里添加httppost方式的[ManageUpdate]action
/// <summary>
/// 修改栏目信息
/// </summary>
/// <param name="category"></param>
/// <returns></returns>
public ActionResult ManageUpdate(Category category)
{
switch (category.Type)
{
case 0:
category.Navigation = "";
break;
case 1:
category.Model = "";
category.ContentView = "";
category.Navigation = "";
break;
case 2:
category.Model = "";
category.CategoryView = "";
category.ContentView = "";
break;
}
categoryRsy = new CategoryRepository();
if (categoryRsy.Update(category))
{
Notice _n = new Notice { Title = "修改栏目成功", Details = "修改栏目成功！", DwellTime = 5, NavigationName = "栏目详细信息", NavigationUrl = Url.Action("ManageDetails", "Category", new { id = category.CategoryId }) };
return RedirectToAction("ManageNotice", "Prompt", _n);
}
else
{
Error _e = new Error { Title = "修改栏目失败", Details = "在修改栏目信息时，未能保存到数据库", Cause = "系统错误", Solution = Server.UrlEncode("<li>返回<a href='" + Url.Action("ManageDetails", "Category", new { id = category.CategoryId }) + "'>栏目详细资料</a>页面，修改信息后重新操作</li><li>联系网站管理员</li>") };
return RedirectToAction("ManageError", "Prompt", _e);
}
}
很简单，首先是判断栏目类型，根据栏目类型清除无关数据，然后将修改保存到数据库。
试一下将“测试栏目”改成“公司简介”
保存成功！
