How to access CodeIgniter user defined models?

Question

When I want to access a function of a user defined model in CodeIgniter inside a custom user defined library it throws

Call to a member function Set_wher

Answer 1

Now i fix the issue just adding $CI =& get_instance(); into that function where i want to fetch previously i declare that $CI =& get_instance(); in another function of that class for which it was not instantiated.

My working code is now..

$CI =& get_instance();

$CI->load->model('home_model');

$CI->home_model->Set_where("film_feature='Y'");
