i have now new structure of my database, but i need to import the old data in the new format. For that reason i want to use the Laravel seeder, but i need somehow to connect to the old database and make select queries and to tell the seeder how to put the data in the new database.
Is that possible ?
Try: Examples:
php artisan iseed my_table
php artisan iseed my_table,another_table
Configure your laravel app to use two mysql connections (How to use multiple database in Laravel), one for the new database, the other for the old one.
I'll fake it like old and new.
In your seeds read from the old database and write into the new.
$old_user = DB::connection('old')->table('users')->get();
foreach ($old_users as $user) {
DB::connection('new')->table('users')->insert([
'name' => $user->name,
'email' => $user->email,
'password' => $user->password,
'old_id' -> $user->id
// ...
]);
}
Make sure to add messages while seeding like $this->command->info('Users table seeded'); or even a progress bar (you can access command line methods) to know at which point of the import you are.
.env variable in your config/database.php as they have precedence over any other setting. You caught me...it has to be get() instead of all() :DDownload package from
Git repo : https://github.com/orangehill/iseed
then update below file src/Orangehill/Iseed/IseedCommand.php
Add below code at line number 75
// update package script
if($this->argument('tables') === null){
$tables = Schema::getConnection()->getDoctrineSchemaManager()->listTableNames();
}
and update getArguments method in same file with below code
array('tables', InputArgument::OPTIONAL, 'comma separated string of table names'),
and then run php artisan iseed so it will get all the tables from your existing db and start creating seeders for all tables
