To update IdentityUser with custom properties using MVC5 and Entity Framework, follow these steps:
Step 1: Add custom properties to the IdentityUser class
Add the custom properties to the IdentityUser class by creating a new class that inherits from IdentityUser. For example:
public class ApplicationUser : IdentityUser
{
public string FirstName { get; set; }
public string LastName { get; set; }
public DateTime DateOfBirth { get; set; }
}
Step 2: Create a database context class
Create a database context class that inherits from IdentityDbContext<ApplicationUser>. This class will represent the database context for your application and will include a DbSet for your custom ApplicationUser class.
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
public ApplicationDbContext() : base("DefaultConnection")
{
}
public static ApplicationDbContext Create()
{
return new ApplicationDbContext();
}
public DbSet<ApplicationUser> ApplicationUsers { get; set; }
}
Step 3: Update the User Manager class
Update the UserManager class to use your custom ApplicationUser class. In the ApplicationUserManager class, update the Create method to return an instance of your ApplicationUserManager class with the custom ApplicationUser class.
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, etc.
// ...
return manager;
}
}
Step 4: Update the AccountController
Update the AccountController to add the custom properties to the RegisterViewModel and ApplicationUser objects. In the Register action, map the values from the RegisterViewModel to the ApplicationUser object.
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Register(RegisterViewModel model)
{
if (ModelState.IsValid)
{
var user = new ApplicationUser { UserName = model.Email, Email = model.Email, FirstName = model.FirstName, LastName = model.LastName, DateOfBirth = model.DateOfBirth };
var result = await UserManager.CreateAsync(user, model.Password);
// ...
}
// ...
}
Step 5: Update the database Finally, update the database to include the new custom properties. Run the following command in the Package Manager Console:
Update-Database
This will create a migration to add the new properties to the database and update the database schema.
After these steps, you should be able to update the IdentityUser with custom properties using MVC5 and Entity Framework.
To extend the IdentityUser class with a custom property, you can create a new class that inherits from IdentityUser and add your custom property to it. Here are the steps to do so:
Create a new class that inherits from IdentityUser. This class should have a public property that represents your custom property. Here's an example:
public class ApplicationUser : IdentityUser
{
public string CustomProperty { get; set; }
}
Modify the ApplicationDbContext class to use your custom user class instead of the default IdentityUser class. You can do this by specifying the type parameter for the IdentityDbContext class. Here's an example:
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
: base(options)
{
}
// DbSets and other context configuration here
}
In this example, we're specifying ApplicationUser as the type parameter for IdentityDbContext.
Modify the ConfigureServices method in the Startup class to use your custom user class. You can do this by adding a call to the AddIdentity method and specifying your custom user class as the type parameter. Here's an example:
services.AddIdentity<ApplicationUser, IdentityRole>()
.AddEntityFrameworkStores<ApplicationDbContext>()
.AddDefaultTokenProviders();
In this example, we're specifying ApplicationUser as the type parameter for AddIdentity.
Use your custom user class in your controllers or services. Here's an example of how to create a new user with a custom property:
var user = new ApplicationUser { UserName = "[email protected]", CustomProperty = "custom value" };
var result = await _userManager.CreateAsync(user, "password123");
In this example, we're creating a new ApplicationUser instance with a username and a custom property value, and then using the UserManager to create the user with a password.
With these steps, you should now be able to extend the IdentityUser class with a custom property and use it in your application. Note that you may need to customize the ApplicationUser class or the IdentityDbContext depending on your specific use case.
You can use Entity Framework to reset the identity seed of a LocalDB table by executing a raw SQL query that includes the DBCC CHECKIDENT command. The DBCC CHECKIDENT command is a Transact-SQL statement that checks the current identity value for a specified table and, if necessary, resets the seed value.
Here's an example of how to reset the identity seed of a LocalDB table using Entity Framework:
using (var context = new MyDbContext())
{
var tableName = "MyTable";
var identitySeed = 1;
var query = $"DBCC CHECKIDENT ('{tableName}', RESEED, {identitySeed})";
context.Database.ExecuteSqlCommand(query);
}
In this example, MyDbContext is the DbContext class for your LocalDB database. The tableName variable is set to the name of the table whose identity seed you want to reset, and the identitySeed variable is set to the new seed value.
The query variable is then set to a string that includes the DBCC CHECKIDENT command with the RESEED option and the new seed value. The ExecuteSqlCommand method of the Database property is called with the query parameter to execute the raw SQL command.
Note that executing a raw SQL query can be risky and can expose your application to SQL injection attacks. You should always validate and sanitize any user input before using it in a raw SQL query. Additionally, resetting the identity seed of a table can affect the integrity of your data, so you should use this approach with caution and make sure to backup your data before making any changes.
