Maybe any error when you upload the image, you can debug your php source why error happened, like adding var_dump($error) in 1st condition (if (!$this->upload->do_upload() || !$this->form_validation->run()) ) and comment "redirect('admin_news_adds');" just for debugging condition.
public function update_news(){
$config['upload_path'] = './assets/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '200000';
$config['max_width'] = '200000';
$config['max_height'] = '200000';
$config['new_image'] = './assets/';
$config['overwrite'] = TRUE;
$this->load->library('upload', $config);
$this->form_validation->set_rules('title', 'News Title', 'required|xss_clean');
$this->form_validation->set_rules('description', 'News Description', 'required|xss_clean');
if (!$this->upload->do_upload() || !$this->form_validation->run()) {
$error = array('error' => $this->upload->display_errors());
var_dump($error);
//redirect('admin_news_adds');
} else {
$data = $this->upload->data();
$this->thumb($data);
$id = $this->uri->segment(3);
$file = array(
'img_name' => $data['raw_name'],
'thumb_name' => $data['raw_name'] . '_thumb',
'ext' => $data['file_ext'],
'news_date' => date("l , F j, Y "),
'title' => $this->input->post('title'),
'status' => 1,
'news_description' => $this->input->post('description'),
);
$this->User->update_news($file,$id);
$data = array('upload_data' => $this->upload->data());
redirect('admin_news_add');
}
}

You have two forms. First when you call form
<?php echo form_open_multipart('edit_news/update_news'); ?>
And inside foreach block
<form action="<?php echo base_url() . "edit_news/update_news/". $n->news_id; ?>"
method="post" class="form-horizontal" role="form">
which contain Button element. Because uploading need form attribute enctype set to multipart/form-data, your inner form does not have this so no file upload took place.

试试这个
public function update_news()
{
$this->load->library('upload');
$config['upload_path'] = getcwd().'/assets/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '200000';
$config['max_width'] = '200000';
$config['max_height'] = '200000';
$config['overwrite'] = TRUE;
$this->upload->initialize($config);
$this->form_validation->set_rules('title', 'News Title', 'required|xss_clean');
$this->form_validation->set_rules('description', 'News Description', 'required|xss_clean');
if (!$this->upload->do_upload() || !$this->form_validation->run()) {
$error = array('error' => $this->upload->display_errors());
$this->load->view('your view name', $error);
} else {
$data = $this->upload->data();
$this->thumb($data);
$id = $this->uri->segment(3);
$file = array(
'img_name' => $data['raw_name'],
'thumb_name' => $data['raw_name'] . '_thumb',
'ext' => $data['file_ext'],
'news_date' => date("l , F j, Y "),
'title' => $this->input->post('title'),
'status' => 1,
'news_description' => $this->input->post('description'),
);
$this->User->update_news($file,$id);
$data = array('upload_data' => $this->upload->data());
redirect('admin_news_add');
}
}
