my controller
$user = $this->session->userdata(‘userid’);
        $e =  new Profile();
      $e->user_id = $this->session->userdata(‘userid’);
      $e->Name = $this->input->post(‘pname’);
      $e->Sex =  $this->input->post(‘sex’);
      $e->City =  $this->input->post(‘city’);
      $e->DOB = $this->input->post(‘stats’);
      $e->Interests = $this->input->post(‘interests’);
      $e->image_loc = $u->image_loc = $newfilepath;
      $e = Doctrine::getTable(‘Profile’)->find($user);
      $e-save();
      $this->load->view(‘profile’);

Call to undefined function save()

my model is
<?php
class Profile extends Doctrine_Record {

public function setTableDefinition() {
$this->hasColumn('user_id', 'string', 255);
$this->hasColumn('Name', 'string', 255);
$this->hasColumn('City', 'string', 255);
$this->hasColumn('Sex', 'string', 255);
$this->hasColumn('DOB','date');
$this->hasColumn('image_loc','string',255);
$this->hasColumn('Interests', 'string', 255);


}
 
  public function setUp() {
$this->setTableName('user_profile');
$this->actAs('Timestampable');
}

 
}
