Use ASP. NET MVC3 + EF + Jquery to create a text live broadcast system (3)

 

In the previous article, the login function was simply implemented. In this article, the background framework was first merged.

Build a framework

Or use the template mentioned above, which uses the frameset framework. net mvc, how to use the frameset framework, I recommend you read an article in ASP. net mvc uses the frameset framework !.

In the previous article, we created a new Admin folder under the View folder. Therefore, we should first create a new AdminController and add the following code:

public class AdminController : Controller{    //    // GET: /Admin/    [Authorize]    public ActionResult Index()    {        return View("Index");    }    [Authorize]    public ActionResult Top()    {        return View("Top");    }    [Authorize]    public ActionResult Left()    {        return View("Left");    }}

Create the following view:

In Index. cshtml, use frameset to reference Top. cshtml and Left. cshtml. For details, refer to the article above.

<frame src="@Url.Action("Top")" noresize="noresize" frameborder="NO" name="topFrame" scrolling="no" marginwidth="0" marginheight="0" target="main" />

Modify the LogOn action in AccountController as follows:

/// POST:/Account/LogOn [HttpPost] public ActionResult LogOn (LogOnViewModel model) {if (ModelState. isValid) {if (context. users. any (u => u. userName = model. userName & u. password = model. password) {FormsAuthentication. setAuthCookie (model. userName, false); // return RedirectToAction ("Index", "Admin");} else {ModelState. addModelError ("", "incorrect user name or password") ;}} return View (model );}

In this way, the framework is basically ready, and the effect is as follows:

Implement User Management

To implement user management, we first modify LiveText. the User entity in the Domain project, because we use the database generated by Code-First, if the entity is modified, an error will occur again during the next operation, so the First thing to do is in LiveText. create a LiveTextDbInitializer class in the Model folder of the WebUI project to regenerate the database when the object changes.

Public class LiveTextDbInitializer: DropCreateDatabaseIfModelChanges <LiveTextDbContext>

{

Protected override void Seed (LiveTextDbContext context)

{

Context. Users. Add (new Domain. Entities. User

{

UserName = "admin ",

Password = "admin"

});

Base. Seed (context );

}

}

Register it in the Application_Start method in Global. asax:

 

Database. SetInitializer (new LiveTextDbInitializer ());

Now we can modify the User entity. If you have written them at the beginning, you don't need to modify them now ,. The modified code is as follows:

 

Public class User

{

/// <Summary>

/// User ID

/// </Summary>

Public virtual int UserID {get; set ;}

/// <Summary>

/// User Name

/// </Summary>

[Required (ErrorMessage = "cannot be blank")]

[StringLength (30)]

[Display (Name = "username")]

Public virtual string UserName {get; set ;}

/// <Summary>

/// User Password

/// </Summary>

[Required (ErrorMessage = "cannot be blank")]

[DataType (DataType. Password)]

[StringLength (30, MinimumLength = 5, ErrorMessage = "The minimum password length is 5 characters")]

[Display (Name = "password")]

Public virtual string Password {get; set ;}

Next, create a UserController and select it as shown in.

}

Finally, modify the hyperlink in Left. cshtml:

<Li> <a href = "@ Url. Action (" Create "," User ")" target = "main"> Add a User </a> </li>

<Li> <a href = "@ Url. Action (" Index "," User ")" target = "main"> User List </a> </li>

OK, run the program again:

No style, so it's hard to see

Implement text live Management

First, implement category management.

Modify the Category object.

Public class Category {// <summary> // Category ID // </summary> public virtual int CategoryID {get; set ;} /// <summary> /// category name /// </summary> [Required (ErrorMessage = "cannot be blank")] [Display (Name = "category Name")] public virtual string Name {get; set ;} /// <summary >/// Title set /// </summary> public virtual List <Title> Titles {get; set ;}}

Create a CategoryController.

Now, the category management is complete. Let's take a look at the running effect:

Second, achieve Title Management

First, modify the Title object.

Public class Title {// <summary> /// Title number /// </summary> public virtual int TitleID {get; set ;} /// <summary> /// category ID /// </summary> [Required (ErrorMessage = "category cannot be blank")] public virtual int CategoryID {get; set ;}//< summary> /// title name /// </summary> [Required (ErrorMessage = "title cannot be blank")] [Display (Name = "title Name")] public virtual string Name {get; set ;} /// <summary> /// Category /// </summary> public virtual Category {get; set ;} /// <summary> /// Text set /// </summary> public virtual List <Text> Texts {get; set ;}}

Create TitleController.

Now, let's take a look at the running effect:

Implement Text Management

First, modify the Text object.

Public class Text {// <summary> // Text number /// </summary> public virtual int TextID {get; set ;} /// <summary> /// title no. /// </summary> [Required (ErrorMessage = "title cannot be blank")] [Display (Name = "title")] public virtual int TitleID {get; set ;} /// <summary> /// publisher /// </summary> [Required (ErrorMessage = "publisher cannot be blank")] [Display (Name = "publisher")] public virtual string Prolocutor {get; set ;} /// <summary> /// post content /// </summary> [Required (ErrorMessage = "post content cannot be blank")] [Display (Name = "posted content")] public virtual string ProContent {get; set ;} /// <summary> /// title /// </summary> [Display (Name = "posting time")] public virtual DateTime ProDate {get; set ;} /// <summary> /// Title // </summary> [Display (Name = "Title")] public virtual Title {get; set ;}}

Create TextController.

OK. Check the running result:

So far today, JQuery will be used in the next article.
