三、通用增加、修改
首先添加一个CreateEditView.aspx视图
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<%Html.RenderPartial(ViewData["PartialName"].ToString()); %>
</asp:Content>
然后添加两个Partial视图News.ascx和User.ascx，这两个视图是分别基于News和User类的强类型视图，具体内容参加源码。
接下来我们添加相应的Controller
public ActionResult CreateEditView(string partialName, int? key)
{
ViewData["PartialName"] = partialName;
RepositoryBase repositoryBase = new RepositoryBase(partialName);
ICommonTable table;
if (key == null)
{
table = repositoryBase.CreateNew();
}
else
{
table = repositoryBase.Get(key ?? 0);
}
return View("CreateEditView", table);
}
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult CreateEditView(string partialName, int? key, FormCollection formCollection)
{
RepositoryBase repositoryBase = new RepositoryBase(partialName);
ICommonTable bllTable;
if (key == null)
{
bllTable = repositoryBase.CreateNew();
}
else
{
bllTable = repositoryBase.Get(key ?? 0);
}
this.UpdateModel(bllTable, true);
if (key == null)
{
Context.GetContext().GetTable(repositoryBase.EntityType).InsertOnSubmit(bllTable);
}
Context.GetContext().SubmitChanges();
return RedirectToAction(partialName+"List");//返回到list
}
这里边大家可能有疑问的就是this.UpdateModel(bllTable, true);这个方法在mvc框架中并不存在，这是我添加的扩展方法，这个地方如果使用UpdateModel(bllTable)虽然编译不会报错，但也没有更新成功，查了一下mvc的源码，问题就出在如下源码中：
|
protected internal bool TryUpdateModel<TModel>(TModel model, string prefix, string[] includeProperties, string[] excludeProperties, IDictionary<string, ValueProviderResult> valueProvider) where TModel : class { |
