python 3.x - In a nested for-loop, how can I access the outer loop index in a jinja template? -

-

{{loop.index}} correctly dereferences innermost loop. i'm not seeing way identify loop index i'd like, however, if have more 1 loop nested.

http://jinja.pocoo.org/docs/dev/templates/

yes. part of documentation answers question!

the special loop variable points innermost loop. if it’s desired have access outer loop it’s possible alias it:

<table> {% row in table %}   <tr>   {% set rowloop = loop %}   {% cell in row %}     <td id="cell-{{ rowloop.index }}-{{ loop.index }}">{{ cell }}</td>   {% endfor %}   </tr> {% endfor %} </table>

Deploying Qt Application on Android is really slow? -

-
as may know there 3 ways deploy qt application on android : use ministro service install qt deploy local qt libraries temporary directory bundle qt libraries in apk the first method takes 30 seconds , needs install apk . ministro . second takes 1 minute me ! , anytime try run program qt creator pushes qt libraries device. third 1 makes .apk file big , again takes 1 minute me. think situation that's not reasonable develop android application using qt. there way make deploying process faster? almost full year since op , things have not changed @ all. deployment of 7 mb apk takes on minute , half project compiles in 5 seconds. reason answering not problem got resolved, offer alternative solution. i've implemented "workaround" consisting of 2 applications work in tandem - 1 on pc , 1 on device - created compile files remotely, turned out faster alternative deployment well. on host create application launches compilation in separate process, when do...
