codeigniter access model from library - codeigniter

Question

I am trying to integrate the following code into my project. it is held in a library
function do_std_login($email, $password) {
$CI =& get_instance();
$login = $CI->users_model->login($email, md5($password));
if($login){
$session_array = array(
'user_id' => $login->user_id,
'name' => $login->name,
'type' => 'Standard'
);
$CI->session->set_userdata($session_array);
// Update last login time
$CI->users_model->update_user(array('last_login' => date('Y-m-d H:i:s', time())), $login->user_id);
return true;
} else {
$this->errors[] = 'Wrong email address/password combination';
return false;
}
}
I am calling it this way:
$login = $this->jaclogin->do_std_login($this->input->post('email'),$this->input->post('password'));
but when I run it I get the following error
A PHP Error was encountered
Severity: Notice
Message: Undefined property: Login::$users_model
Filename: libraries/jaclogin.php
Line Number: 45
I have check I am do load the correct library in the codeigniter autoload file.
Any Ideas?
Thanks

Using your CI instance, load your model explicitly in the library like so..
function do_std_login($email, $password) {
$CI =& get_instance();
//--------------
$CI->load->model('users_model'); //<-------Load the Model first
//--------------
$login = $CI->users_model->login($email, md5($password));
if($login){
$session_array = array(
'user_id' => $login->user_id,
'name' => $login->name,
'type' => 'Standard'
);
$CI->session->set_userdata($session_array);
// Update last login time
$CI->users_model->update_user(array('last_login' => date('Y-m-d H:i:s', time())), $login->user_id);
return true;
} else {
$this->errors[] = 'Wrong email address/password combination';
return false;
}
}
