I want to show single blog news by slug but I do not know

Blog Controller :

```html
        public function show_news($slug)
        {
          $page_data['page_title']  = 'News';
          $page_data['news_item'] = $this->blog_model->get_news($slug);

          $this->template->load('frontend/blog_news',$page_data);

        }
```

Blog Model : 

```html
  function get_news($slug)
    {
      $slugs = urldecode($slug);
       $query = $this->db->get_where('blogposts', array('slug' => $slugs));
if($query->num_rows() > 0 ){
 if($this->db->get_Where('blogposts', array('slug'=>$slugs))->row()->status == '1'){
  return $query->row_array();
     }
  }
    }
```

my route :

```html
$route['blog/(:any)/news/(:any)'] = "blog/show_news/$1/$2";
```
