codeigniter model problem

I updated to CI 2.0 now my models stopped working.I used

 parent::__construct();

And i defined the class correctly extends CI_Model but even using a simple ge开发者_运维知识库t all

$query = $this->db->get('mytable');

Returns an error

 Call to a member function get() on a non-object in models\crudModel.php on line 13

It sounds very much like you are not loading the database library - have you got it in your config/autoload.php? It is sensible to autoload it if you use the database library in all your controllers:

$autoload['libraries'] = array( 'database' );
