Auto-loading Models in mvc

Auto-loading Models in mvc

If you want to perform particular model globally in your application, you can tell CodeIgniter in mvc pattern  to auto-load model during system execution. This is done by file the application/config/autoload.php file and adding the model to the autoload array.

Once a model is loaded it does NOT means to  connect automatically database. The below options for connecting are available in CodeIgniter and mvc:

·         You can connect database from a model using the standard database methods , either from within your Controller class or your Model class.

·         You can tell the model loading function to auto-connect by passing TRUE (boolean) via the third parameter, and connectivity settings, as defined in your database config file will be used:

$this->load->model('Model_name', '', TRUE);

You can manually pass database connectivity settings via the third parameter:

$config['hostname'] = "localhost";
$config['username'] = "myusername";
$config['password'] = "mypassword";
$config['database'] = "mydatabase";
$config['dbdriver'] = "mysql";
$config['dbprefix'] = "";
$config['pconnect'] = FALSE;
$config['db_debug'] = TRUE;

$this->load->model('Model_name', '', $config);
