  3. Internet Application • To learn ASP.NET MVC, we will Build an Internet Application • We will build an Internet application that supports adding, editing, deleting, and listing of information stored in a database. Part I: Creating the Application Part II: Exploring the Application Folders Part III: Adding Styles and a Consistent Look (Layout). Part IV: Adding a Controller Part V: Adding Views for Displaying the Application Part VI: Adding a Database. Part VII: Adding a Data Model T2-Lecture-15 Ahmed Mumtaz Mustehsan www.w3schools.com

  4. Part VI: Adding a Database.

  5. Creating the Database Visual Web Developer comes with a free SQL database called SQL Server Compact. The database needed for this lesson can be created with these simple steps: • Right-click the App_Datafolder in the SolutionExplorer window • Select Add, New Item • Select SQLServerCompactLocalDatabase* • Name the database Movies.sdf. • Click the Add button T2-Lecture-15 Ahmed Mumtaz Mustehsan www.w3schools.com

  6. Creating the Database • Visual Web Developer automatically creates the database in the App_Datafolder. If SQL Server Compact Local Database is not an available option, means SQL Server Compact not installed. • If SQL Server Compact not installed on your computer. Install it from this link: SQL Server Compact T2-Lecture-15 Ahmed Mumtaz Mustehsan www.w3schools.com

  7. Adding a Database Table • Double-clicking the Movies.sdf file in the App_Data folder will open a DatabaseExplorer window. • To create a new table in the database, right-click the Tables folder, and select CreateTable. • Create the following columns: T2-Lecture-15 Ahmed Mumtaz Mustehsan www.w3schools.com

  8. Adding a Database Table • ID is an integer (whole number) used to identify each record in the table. • Title is a 100 character text column to store the name of the movie. • Director is a 100 character text column to store the director's name. • Date is a datetime column to store the release date of the movie. • After creating the columns described above, you must make the ID column the table's primarykey (record identifier). • To do this, click on the column name (ID) and select Primary Key. Also, in the Column Properties window, set the Identity property to True: T2-Lecture-15 Ahmed Mumtaz Mustehsan www.w3schools.com

  9. T2-Lecture-15 Ahmed Mumtaz Mustehsan www.w3schools.com

  10. Adding a Database Table • When you have finished creating the table columns, save the table and name it MovieDBs. Note: • We have deliberately named the table "MovieDBs" (ending with s). • Later we willname it "MovieDB" used for the data model. • It looks strange, but this is the naming convention you have to use to make the controller connect to the database table. T2-Lecture-15 Ahmed Mumtaz Mustehsan www.w3schools.com

  11. Adding Database Records • Use Visual Web Developer to add some test records to the movie database. • Double-click the Movies.sdffile in the App_Datafolder. • Right-click the MovieDBstable in the Database Explorer window and select ShowTableData. • Add some records: Note:The ID column is updated automatically. You should not edit it. T2-Lecture-15 Ahmed Mumtaz Mustehsan www.w3schools.com

  12. Part VII: Adding a Data Model.MVC Models

  13. Models The MVC Model contains all application logic: • business logic, • validation logic, • data access logic, • (except pure view and controller logic.) MVC, models are used for both: Hold and manipulate application data. T2-Lecture-15 Ahmed Mumtaz Mustehsan www.w3schools.com

  14. The Models Folder • The Models Folder contains the classes that represent the application model. • Visual Web Developer automatically creates an AccountModels.cs file that contains the models for application security. • AccountModels contains: • A LogOnModel, • A ChangePasswordModel, and • A RegisterModel. T2-Lecture-15 Ahmed Mumtaz Mustehsan www.w3schools.com

  15. Adding a Database Model • The database model needed for this Lesson can be created with these simple steps: In the Solution Explorer, • right-click the Models folder, select Add and Class. • Name the class MovieDB.cs, and click Add. Edit the class: T2-Lecture-15 Ahmed Mumtaz Mustehsan www.w3schools.com

  16. T2-Lecture-15 Ahmed Mumtaz Mustehsan www.w3schools.com

  17. Adding a Database Model Note: • We have deliberately named the model class "MovieDB". • In the previous section, we used the name "MovieDBs" (ending with s) used for the database table. It looks strange, but this is the naming convention we have to use to make the model connect to the database table. T2-Lecture-15 Ahmed Mumtaz Mustehsan www.w3schools.com

  18. Adding a Database Controller The database controller needed for this lesson can be created with these simple steps: Re-Build your project: • Select Debug, and then BuildMvcDemo from the menu. • In the Solution Explorer, right-click the Controllers folder, and select Add and Controller • Set controller name to MoviesController • Select template: Controllerwithread/writeactionsandviews, usingEntityFramework • Select model class: MovieDB (MvcDemo.Models) • Select data context class: MovieDBContext (MvcDemo.Models) • Select views Razor (CSHTML) • Click Add T2-Lecture-15 Ahmed Mumtaz Mustehsan www.w3schools.com

  19. Adding a Database Controller Visual Web Developer will create the following files: • A MoviesController.cs file in the Controllers folder • A Movies folder in the Views folder T2-Lecture-15 Ahmed Mumtaz Mustehsan www.w3schools.com

  20. Adding Database Views The following files are automatically created in the Movies folder: • Create.cshtml • Delete.cshtml • Details.cshtml • Edit.cshtml • Index.cshtml T2-Lecture-15 Ahmed Mumtaz Mustehsan www.w3schools.com

  21. Adding a Connection String • Add the following element to the <connectionStrings> element in your Web.config file: <add name="MovieDBContext"connectionString="Data Source=|DataDirectory|\Movies.sdf"providerName="System.Data.SqlServerCe.4.0"/> T2-Lecture-15 Ahmed Mumtaz Mustehsan www.w3schools.com

  22. MVC Application Security • The Models Folder contains the classes that represent the application model. • Visual Web Developer automatically creates an AccountModels.cs file that contains the models for application authentication. AccountModels contains A LogOnModel, A ChangePasswordModel, and A RegisterModel: T2-Lecture-15 Ahmed Mumtaz Mustehsan www.w3schools.com

  23. Account Model T2-Lecture-15 Ahmed Mumtaz Mustehsan www.w3schools.com

  24. The Change Password Model public class ChangePasswordModel{[Required][DataType(DataType.Password)][Display(Name = "Current password")]public string OldPassword { get; set; }[Required][StringLength(100, ErrorMessage = "The {0} must be at least {2}      characters long.", MinimumLength = 6)][DataType(DataType.Password)][Display(Name = "New password")]public string NewPassword { get; set; }[DataType(DataType.Password)][Display(Name = "Confirm new password")][Compare("NewPassword", ErrorMessage = "The new password and confirmation password do not match.")]public string ConfirmPassword { get; set; }} T2-Lecture-15 Ahmed Mumtaz Mustehsan www.w3schools.com

  25. A Logon Model public class LogOnModel{[Required][Display(Name = "User name")]public string UserName { get; set; }[Required][DataType(DataType.Password)][Display(Name = "Password")]public string Password { get; set; }[Display(Name = "Remember me?")]public bool RememberMe { get; set; }} T2-Lecture-15 Ahmed Mumtaz Mustehsan www.w3schools.com
