Custom identity user and extending profile MVC

Custom identity user and extending profile MVC

In ASP.NET MVC, you can create a custom identity user and extend the user profile using the IdentityUser class and IdentityDbContext class provided by the ASP.NET Identity framework. Here are the steps to create a custom identity user and extend the user profile in MVC:

  • Create a new class that derives from IdentityUser to represent your custom identity user. For example:
public class ApplicationUser : IdentityUser { public string FirstName { get; set; } public string LastName { get; set; } public DateTime? DateOfBirth { get; set; } }

In this example, we add some additional properties to the ApplicationUser class to represent the user's first name, last name, and date of birth.

  • Create a new class that derives from IdentityDbContext to represent your application's database context. For example:
public class ApplicationDbContext : IdentityDbContext<ApplicationUser> { public ApplicationDbContext() : base("DefaultConnection") { } public static ApplicationDbContext Create() { return new ApplicationDbContext(); } protected override void OnModelCreating(DbModelBuilder modelBuilder) { base.OnModelCreating(modelBuilder); // Customize the default schema for Identity tables modelBuilder.HasDefaultSchema("Identity"); } }

In this example, we create a new database context class ApplicationDbContext that derives from IdentityDbContext<ApplicationUser>, which specifies our custom ApplicationUser class as the user type. We also customize the default schema for Identity tables.

  • Update the ApplicationUserManager class to use your custom ApplicationUser class. For example:
public class ApplicationUserManager : UserManager<ApplicationUser> { public ApplicationUserManager(IUserStore<ApplicationUser> store) : base(store) { } public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options, IOwinContext context) { var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(context.Get<ApplicationDbContext>())); // Configure validation logic for usernames and passwords manager.UserValidator = new UserValidator<ApplicationUser>(manager) { AllowOnlyAlphanumericUserNames = false, RequireUniqueEmail = true }; manager.PasswordValidator = new PasswordValidator { RequiredLength = 8, RequireNonLetterOrDigit = false, RequireDigit = true, RequireLowercase = true, RequireUppercase = true, }; // Configure user lockout defaults manager.UserLockoutEnabledByDefault = true; manager.DefaultAccountLockoutTimeSpan = TimeSpan.FromMinutes(5); manager.MaxFailedAccessAttemptsBeforeLockout = 5; // Configure two factor authentication manager.RegisterTwoFactorProvider("PhoneCode", new PhoneNumberTokenProvider<ApplicationUser> { MessageFormat = "Your security code is {0}" }); manager.RegisterTwoFactorProvider("EmailCode", new EmailTokenProvider<ApplicationUser> { Subject = "Security Code", BodyFormat = "Your security code is {0}" }); manager.EmailService = new EmailService(); manager.SmsService = new SmsService(); var dataProtectionProvider = options.DataProtectionProvider; if (dataProtectionProvider != null) { manager.UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser>(dataProtectionProvider.Create("ASP.NET Identity")); } return manager; } }

In this example, we update the ApplicationUserManager class to use our custom ApplicationUser class and the ApplicationDbContext class that we created in steps 1 and 2.
