[jason3130]

repo field is bytes type so cast to str update before：

      <tr>
                    <td><a href="{{repo}}" target='_blank'>{{repo}}</a></td>

                    <td>{{desc.repo_desc}}</td>
                    <td>{{desc.star}}</td>
                    <td><input type="checkbox" class="del-repo" data={{repo}}></td>
                </tr>

update after: 

  <tr>
                    <td><a href="{{repo.decode('utf-8')}}" target='_blank'>{{ repo.decode('utf-8')}}</a></td>

                    <td>{{desc.repo_desc}}</td>
                    <td>{{desc.star}}</td>
                    <td><input type="checkbox" class="del-repo" data={{repo.decode('utf-8')}}></td>
                </tr>
