Chapter 3 modifying user group operations 3.3, mvc43.3

I. Users
Ii. User Group 
2.1 browsing user groups
2.2 Add a user group
2.3 modify user groups
First open [UserGroupController] and modify [Edit (int Id)] Action

/// <Summary> /// modify the user group /// </summary> /// <param name = "Id"> User Group Id </param> /// <returns> </returns> [AdminAuthorize] public ActionResult Edit (int Id) {userGroupRsy = new UserGroupRepository (); var _ userGroup = userGroupRsy. find (Id); return View (_ userGroup );}

Right-click to add a strong view and modify the view code (similar to adding a user group)

@ Model Ninesky. Models. UserGroup @ {ViewBag. Title = "Modify user group"; Layout = "~ /Views/Layout/_ Manage. cshtml ";} <div class = "left"> <div class = "top"> </div> list on the left </div> <div class = "split"> </div> <div class = "workspace"> <div class = "inside"> <div class = "notebar">  modify user group information </div> @ using (Html. beginForm ("Eidt", "UserGroup") {@ Html. validationSummary (true) <fieldset> <legend> User Group Information </legend> @ Html. hiddenFor (model => model. userGroupId) <ul> <li> <div class = "editor-label"> @ Html. labelFor (model => model. type) </div> <div class = "editor-field"> @ Html. displayTextFor (model => model. type) </div> </li> <div class = "editor- Label "> @ Html. labelFor (model => model. name) </div> <div class = "editor-field"> @ Html. editorFor (model => model. name) @ Html. validationMessageFor (model => model. name) </div> </li> <div class = "editor-label"> @ Html. labelFor (model => model. description) </div> <div class = "editor-field"> @ Html. editorFor (model => model. description) @ Html. validationMessageFor (model => model. description) </div> </li> <li> <Div class = "editor-label"> </div> <div class = "editor-field"> <input type = "submit" value = "save"/> </div> </li> </ul> </fieldset >}</div> <div class = "clear"> </div> @ section Scripts {@ Scripts. render ("~ /Bundles/jqueryval ")}

Modify and process Action [Eidt (UserGroup userGroup)]

[HttpPost] [AdminAuthorize] public ActionResult Eidt (UserGroup userGroup) {userGroupRsy = new UserGroupRepository (); var _ userGroup = userGroupRsy. find (userGroup. userGroupId); if (_ userGroup = null) {Error _ e = new Error {Title = "User Group does not exist", Details = "An Error occurred while modifying the user. The modified User Group does not exist. ", Cause =" this user group has been deleted by another administrator ", Solution = Server. urlEncode ("<li> Returns <a href = '" + Url. action ("List", "UserGroup") + "'> User Group List </a> </li>")}; return RedirectToAction ("ManageError", "Prompt ", _ e);} _ userGroup. name = userGroup. name; _ userGroup. description = userGroup. description; if (userGroupRsy. update (_ userGroup) {Notice _ n = new Notice {Title = "modified successfully", Details = "modified User Group information", DwellTime = 3, NavigationN Ame = "User Group list", NavigationUrl = Url. action ("List", "UserGroup")}; return RedirectToAction ("ManageNotice", "Prompt", _ n );} else {Error _ e = new Error {Title = "failed to update data", Details = "failed to save the modified information to the database when modifying user group information. ", Cause = Server. UrlEncode (" <li> you have not changed the user group information. </Li> <li> unknown database error. </Li> "), Solution = Server. urlEncode ("<li> Returns <a href = '" + Url. action ("List", "UserGroup") + "'> User Group List </a> </li> <li> re-<a href ='" + Url. action ("Edit", "UserGroup", new {id = userGroup. userGroupId}) + "'> modify user group </a> </li>")}; return RedirectToAction ("ManageError", "Prompt", _ e );}}
