The db:seed command invokes the root seeder DatabaseSeeder which can
invoke another seeders using the call() related methods. The root seeder
can be set by the --class command-line option and also by the --seeder
cmd. line option on some other commands like migrate:fresh/refresh.
Seeders can be passed to the Tom application in the similar way like the
migrations using the TomApplication::seeders<>() method or through the
constructor.
Arguments can be passed to the call<>() method, then the seeders run()
method will not be called using the virtual dispatch but using the type
traits. Of course the arguments passed to the call<>() method has to
match with the run() method parameters.
Others:
- unified usingConnection() across all commands, this functionality was
extracted to own class, previous it was a part of the Migrator class,
so now every command even if it doesn't use Migrator can call
the usingConnection() and it correctly sets a default connection and
SQL queries debugging on the base of the -vvv command-line argument
- a default database connection is now required, if not set then
the exception will be thrown
- added example seeders to the Tom application
Migration classes can be named in two formats, CamelCase without the
datetime prefix and snake_case with the datetime prefix.
If the CamelCase name is used then the T_MIGRATION macro has to be
also used in the migration class.
- also added a new validations of the migration class names
