I created my own module, the table is created in the database and in a phtml I can call:
$res = $model->getExample();
and effectively it function is called.
In Model:
protected function _construct() {
$this->_init('table_name', 'column_id');
}
public function getExample(){
$result = $this->getData();
}
but 'result' is empty and I know there're data in a database, so... what's the problem?
CLUES
gettype($this) // is object
$this->load() // Call to a member function load() on a non-object
