_assign_libraries error when adding to the database

Yes - removing the _assign_libraries() call from the core Loader class is likely to break other things.

The problem here is that you're experiencing a unique problem. This is why we tend to think it's something you've changed or done, rather than something wrong with the CI files.

Hmm, I was about to suggest you go through the same process again, only this time checking each time you add a new file, or at least confirming the basic system is working, but re-scanning your original question again I see that this bit might be a problem:

Code:

// controller ...
    function enviar(){
        $this->load->model('pedidos');

Code:

// model ...
class Pedidos_model extends Model{

In your controller, you really need to load the name of your model - in this case Pedidos_model and not the name of your controller (pedidos).

Try changing your controller to:

Code:

$this->load->model('Pedidos_model');
