Migrations by Mat'as Montes
An open source utility for Codeigniter inspired by Ruby on Rails.
The one thing Ruby on Rails has that Codeigniter does not have built in is database migrations. That function to keep track of database chages (versions) and migrate your database to what ever version you need. Migrate up or migrate down. With this library you can now do this.
Copy the files to these locations.
config/migrations.php -> application/config/
libraries/Migrations.php -> application/libraries/
controllers/migrate.php -> applcation/controllers/
The migration files included in this are just examples. You should install them where ever you
point your $config["migrations_path"] to.
$this->load->library('migrations');
$this->migrations->set_verbose(TRUE); // echo statments or not
$this->migrations->version(id); // migrate the database to a particular version
$this->migrations->latest(); // migrate the database to the latest version
$this->migrations->install(); // install to the latest version.
The migrate.php controller just shows the use of these functions. If you are going to use it.
comment out the show_error() in the construct, and put it back in place when you are done.
if ( ! $this->migration->latest())
{
show_error($this->migration->error);
}
if ( ! $this->migration->version(5))
{
show_error($this->migration->error);
}
Included in this git repo is an example CodeIgniter Hook and a basic application/config/hooks.php to show how to enable it. This hook is one of several ways to have migrations run on every page load. You could also place the code into a MY_Controller.
