In this issue, the editor will bring you about how to achieve the background management of user roles in the development of ASP.NETMVC5 website. The article is rich in content and analyzes and describes for you from a professional point of view. I hope you can get something after reading this article.

Role is a function in the website, which is used to distinguish the types of users and divide the permissions of users. This time, role list browsing, role addition, role modification and role deletion are realized.

I. Business logic layer

1. Role model

Ninesky.Core [right]-> add-> class, and enter the class name Role.

Reference System.ComponentModel.DataAnnotations Namespace

Using System.ComponentModel.DataAnnotations;namespace Ninesky.Core {/ role / public class Role {[Key] public int RoleID {get; set;} / name / [Required (ErrorMessage = "must be entered {0}")] [StringLength (20 min length = 2, ErrorMessage = "{2}-{1} characters")] [Display (Name = "name")] public string Name {get Set;} / description / / [StringLength (1000, ErrorMessage = "{0} must be less than {1} characters")] [Display (Name = "description")] public string Description {get; set;}

2. Add table mapping

Open Ninesky.Core/NineskyContext.cs and add Role table mapping

3. Migrate data

1) enable data migration

Go to [Toolbar]-> [tools]-> NuGet package Manager-> package Manager console.

Enter the command Enable-Migrations enter to enable data migration for Ninesk.Core.

Open the Ninesky.Core/Migrations/Configuration.cs file

Change AutomaticMigrationsEnabled = false; to AutomaticMigrationsEnabled = ture; to enable automatic migration.

2), update the data table

Run the command Update-Database. Error: There is already an object named 'Administrators' in the database.

This is because the data migration is enabled after the husband becomes the Administrators table. The view failed to create the Administrators table while updating the table.

Open Server Explorer and select Administrators [right]-> Delete as shown in the figure.

Run Update-Database again after the deletion is successful, and the execution is successful.

Because the administrator account was also deleted when deleting the table just now, remember to open the Administrators table to add an administrator account, and remember that the password can be entered into jZae727K08KaOmKSgOaGzww/XVqGr/PKEgIMkjrcbJI=, which is a 123456 encrypted string.

4. Role management

Ninesky.Core [right]-> add-> class, enter the class name RoleManager, which inherits from BaseManager

Using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace Ninesky.Core {/ role Management / public class RoleManager:BaseManager {}}

II. Display layer

Ninesky.Web/Areas/Control/Controllers [right]-> add-> Controller. Select MVC5 Controller-null, enter the controller name RoleController.

Introduce the namespace Ninesky.Core into the controller

Add the variable private RoleManager roleManager = new RoleManager ()

Add authentication to the controller [AdminAuthorize]

1. Message prompt

During the operation, we often need to prompt for the success, failure and error of the operation, so the model class Prompt is specially designed to prompt.

1), add a class

Ninesky.Web/Models [right]-> add-> Class enter the class name Prompt

The copy code is as follows:

Using System.Collections.Generic;namespace Ninesky.Web.Models {/ prompt / public class Prompt {/ title / public string Title {get; set;} / message / public string Message {get; set;} / button group / public List Buttons {get; set;}

2. Introduce the namespace of the class into the controller

Reference the namespace Ninesky.Web.Models in Rolecontroller.

3. Add a view

In Ninesky.Web/Areas/Control/Views/Shared [right]-> add-> View

@ model Ninesky.Web.Models.Prompt@ {ViewBag.Title = Model.Title;} @ section SideNav {@ Html.Partial ("SideNavPartialView")} @ Html.ActionLink ("Home", "Index", "Home") @ Model.Title @ Model.Title

@ Html.Raw (Model.Message)

@ if (Model.Buttonsinvalid null & & Model.Buttons.Count > 0) {

@ foreach (var item in Model.Buttons) {@ Html.Raw (item+ "")}

}

2. List of administrators

1), return list method (Json mode)

Add the method ListJson () to the control and return the type JsonResoult

/ list [Json] / public JsonResult ListJson () {return Json (roleManager.FindList ());}

2. Add role home page view

Add a view in the index () method [right]->

@ {ViewBag.Title = "role Management" } @ section SideNav {@ Html.Partial ("SideNavPartialView")} @ Html.ActionLink ("Home", "Index", "Home") @ Html.ActionLink ("user Management", "Index", "User") @ Html.ActionLink ("role Management", "Index" "Role") @ section style {@ Styles.Render ("~ / Content/bootstrapplugincss")} @ section scripts {@ Scripts.Render ("~ / bundles/jqueryval") @ Scripts.Render ("~ / bundles/bootstrapplugin") $(document) .ready (function () {/ / form var $table = $('# admingrid') $table.bootstrapTable ({showRefresh: true, showColumns: true, showFooter: true, method: "post", url: "@ Url.Action (" ListJson ")", columns: [{title: "ID", field: "RoleID"}, {title: "name", field: "Name", formatter: function (value, row, index) {return "+ value +"}, {title: "description" Field: "Description"}, {title: "Operation", field: "RoleID", formatter: function (value) {return "delete"}], onLoadSuccess: function () {/ / delete button $("a [data-operation='deleterole']") .click (function () {var id = $(this) .attr ("data-value") BootstrapDialog.confirm ("are you sure you want to delete" + $(this). Parent (). Parent (). Find ("td"). Eq (1). Text () +? " , function (result) {if (result) {$.post ("@ Url.Action (" DeleteJson "," Role ")", {id: id}, function (data) {if (data.Code = = 1) {BootstrapDialog.show ({message: "role deleted successfully", buttons: [{icon: "glyphicon glyphicon-ok") Label: "OK", action: function (dialogItself) {$table.bootstrapTable ("refresh") DialogItself.close ();}}]});} else BootstrapDialog.alert (data.Message);}, "json");}});}); / / Delete button end}}); / / form end});}

3. Navigation view

The navigation view is displayed on the left side of the view to navigate the functions under the controller

Ninesky.Web/Areas/Control/Views/Role [right]-> add-> View

User Management @ Html.ActionLink ("role add", "Add", "Role") @ Html.ActionLink ("role Management", "Index", "Role")

4. Add roles

1), add method

Add an Add method to the controller

The copy code is as follows:

/ / add / public ActionResult Add () {return View ();}

2), add a view

Right-click on the method to add a view

@ model Ninesky.Core.Role@ {ViewBag.Title = "add roles" } @ section SideNav {@ Html.Partial ("SideNavPartialView")} @ Html.ActionLink ("Home", "Index", "Home") @ Html.ActionLink ("user Management", "Index", "User") @ Html.ActionLink ("role Management", "Index", "Role") add roles @ using (Html.BeginForm ()) {@ Html.AntiForgeryToken () @ Html.ValidationSummary (true, " New {@ class = "text-danger"}) @ Html.LabelFor (model = > model.Name, htmlAttributes: new {@ class = "control-label col-md-2"}) @ Html.EditorFor (model = > model.Name, new {htmlAttributes = new {@ class = "form-control"}}) @ Html.ValidationMessageFor (model = > model.Name, ", new {@ class =" text-danger "}) @ Html.LabelFor (model = > model.Description HtmlAttributes: new {@ class = "control-label col-md-2"}) @ Html.EditorFor (model = > model.Description, new {htmlAttributes = new {@ class = "form-control"}) @ Html.ValidationMessageFor (model = > model.Description, "", new {@ class = "text-danger"}) @ section Scripts {@ Scripts.Render ("~ / bundles/jqueryval")}

3) add the receiving and processing method of submitted data

Add the post method of Add method to the controller

[HttpPost] [ValidateAntiForgeryToken] public ActionResult Add (Role role) {if (ModelState.IsValid) {if (roleManager.Add (role). Code = = 1) {return View ("Prompt", new Prompt () {Title = "role added successfully", Message = "you have successfully added roles [" + role.Name+ "]", Buttons = new List () {"role Management", "continue to add"}}) } return View (role);}

5. Modification of administrator data

1), add method

Add the Modify method to the controller.

/ modify / RoleID / public ActionResult Modify (int id) {var _ role = roleManager.Find (id); if (_ role = = null) return View ("Prompt", new Prompt () {Title = "error", Message = "roles where ID is [" + id + "] does not exist", Buttons = new List () {"role Management"}); return View (_ role) }

2), add a view

Right-click to add a view in the method
