Question

I have a simple question. I want to start using CodeIgniter migrations. But there is no migrations.php file in my config folder, like it says in the documentation. Also, do I need to manually create the migrations folder at the application folder level?

Answer 1

It’s odd that your application/config/migration.php file wasn’t included in the download, however… Even though the config file isn’t there, the migration library will (or should) still be in your CodeIgniter system/libraries folder.

There are three config variables as part of the default migration.php config file:

/*
|--------------------------------------------------------------------------
| Enable/Disable Migrations
|--------------------------------------------------------------------------
|
| Migrations are disabled by default but should be enabled 
| whenever you intend to do a schema migration.
|
*/
$config['migration_enabled'] = FALSE;


/*
|--------------------------------------------------------------------------
| Migrations version
|--------------------------------------------------------------------------
|
| This is used to set migration version that the file system should be on.
| If you run $this->migration->latest() this is the version that schema will
| be upgraded / downgraded to.
|
*/
$config['migration_version'] = 0;


/*
|--------------------------------------------------------------------------
| Migrations Path
|--------------------------------------------------------------------------
|
| Path to your migrations folder.
| Typically, it will be within your application path.
| Also, writing permission is required within the migrations path.
|

$config['migration_path'] = APPPATH . 'migrations/';
