Syntax - $this->load->model('model_name');
Practice - $this->load->model('home_model');
If you would like your model assigned to a different object name you can specify it via the second parameter of the loading method:
Syntax -
$this->load->model('model_name', 'foobar');
$this->foobar->method();
Practice -
$this->load->model('home_model', 'home');
$this->home->get_data();
