我对 ION Auth 库有疑问。我想编辑现有组，当我尝试 dedit 时出现此错误：

错误在哪里，我探索了所有和 CI doc，但一切看起来都很好。

致命错误：在第 603 行的 /var/www/ci_balcanrent/beta/modules/user/controllers/user.php 中的非对象上调用成员函数 row()

这是编辑功能的控制器：

   //edit a group
    function edit_group($id) {
        // bail if no group id given
        if (!$id || empty($id)) {
            redirect('user', 'refresh');
        }

        $this->data['title'] = $this->lang->line('edit_group_title');

        if (!$this->ion_auth->logged_in() || !$this->ion_auth->is_admin()) {
            redirect('user', 'refresh');
        }

        $group = $this->ion_auth->group($id)->row();

        //validate form input
        $this->form_validation->set_rules('group_name', $this->lang->line('edit_group_validation_name_label'), 'required|alpha_dash|xss_clean');
        $this->form_validation->set_rules('group_description', $this->lang->line('edit_group_validation_desc_label'), 'xss_clean');

        if (isset($_POST) && !empty($_POST)) {
            if ($this->form_validation->run() === TRUE) {
                $group_update = $this->ion_auth->update_group($id, $_POST['group_name'], $_POST['group_description']);

                if ($group_update) {
                    $this->session->set_flashdata('success', $this->lang->line('edit_group_saved'));
                } else {
                    $this->session->set_flashdata('error', $this->ion_auth->errors());
                }
                redirect("user", 'refresh');
            }
        }

        //set the flash data error message if there is one
        $this->data['message'] = (validation_errors() ? validation_errors() : ($this->ion_auth->errors() ? $this->ion_auth->errors() : $this->session->flashdata('error')));

        //pass the user to the view
        $this->data['group'] = $group;

        $this->data['group_name'] = array(
            'name' => 'group_name',
            'id' => 'group_name',
            'type' => 'text',
            'value' => $this->form_validation->set_value('group_name', $group->name),
        );
        $this->data['group_description'] = array(
            'name' => 'group_description',
            'id' => 'group_description',
            'type' => 'text',
            'value' => $this->form_validation->set_value('group_description', $group->description),
        );

        $this->template->build('auth/edit_group', $this->data);
    }

603 行 $group = $this->ion_auth->group($id)->row();

模型 ：

/**
     * group
     *
     * @return object
     * @author Ben Edmunds
     **/
    public function group($id = NULL)
    {
        $this->trigger_events('group');

        if (isset($id))
        {
            $this->db->where($this->tables['groups'].'.id', $id);
        }

        $this->limit(1);

        return $this->groups();
    }

看法：

<?php echo form_open(current_url());?>

      <p>
            <?php echo lang('create_group_name_label', 'group_name');?> <br />
            <?php echo form_input($group_name);?>
      </p>

      <p>
            <?php echo lang('edit_group_desc_label', 'description');?> <br />
            <?php echo form_input($group_description);?>
      </p>

      <p><?php echo form_submit('submit', lang('edit_group_submit_btn'));?></p>

<?php echo form_close();?>

$group = $this->ion_auth->group($id)->row();

问题 ：

$this->ion_auth->group($id)返回group类对象。所以你不能从类中调用数据库row()方法。group
