I\'m trying to automatically generate my database if it doesn\'t exists and run the Seed()
method to populate the data. In my Database Context constructor I have th
I ended up with this Configuration
class:
public class Configuration : DbMigrationsConfiguration
{
private readonly bool _pendingMigrations;
public Configuration()
{
AutomaticMigrationsEnabled = true;
// Check if there are migrations pending to run, this can happen if database doesn't exists or if there was any
// change in the schema
var migrator = new DbMigrator(this);
_pendingMigrations = migrator.GetPendingMigrations().Any();
// If there are pending migrations run migrator.Update() to create/update the database then run the Seed() method to populate
// the data if necessary
if (_pendingMigrations)
{
migrator.Update();
Seed(new Context.MyDBContext());
}
}
protected override void Seed(Context.MyDBContext context)
{
// Microsoft comment says "This method will be called after migrating to the latest version."
// However my testing shows that it is called every time the software starts
// Run whatever you like here
// Apply changes to database
context.SaveChanges();
base.Seed(context);
}
}
So on this way the Seed()
method is called when the database is created and also when there are pending migrations.
This is my MyDBContext
class:
public class MyDBContext: DbContext
{
public MyDBContext() : base(AppSettings.DBConnectionString)
{
}
public static MyDBContext Create()
{
return new MyDBContext();
}
public DbSet Users { get; set; }
public DbSet Entries { get; set; }
}
