Thanks Stifan,
I see how can I do that for the whole query.
How can I do this row-wise? Can I create a "count_db" variable per row? As
I'm grouping by game and counting how many entries I have per game (after
grouping them), I would like to show the count per row.
The closest I got so far is by printing the whole row using:
<li>{{=r}}
{{=A(r.probdata.game,_href=URL('list_problems_by_game',args=r.probdata.game))}}</li>
And getting the result below:
- <Row {'probdata': {'game': '338841246'}, '_extra':
{'COUNT("probdata"."game")': 1L}}> 338841246
<http://127.0.0.1:8000/paravolcar5/default/list_problems_by_game/338841246>
- <Row {'probdata': {'game': '338978835'}, '_extra':
{'COUNT("probdata"."game")': 2L}}> 338978835
<http://127.0.0.1:8000/paravolcar5/default/list_problems_by_game/338978835>
- <Row {'probdata': {'game': '338995915'}, '_extra':
{'COUNT("probdata"."game")': 2L}}> 338995915
<http://127.0.0.1:8000/paravolcar5/default/list_problems_by_game/338995915>
But I just want the {'COUNT("probdata"."game")': 1L} part of the row.
Which for the lines above it would be something like this:
- Game 338841246
<http://127.0.0.1:8000/paravolcar5/default/list_problems_by_game/338841246>
1
- Game 338978835
<http://127.0.0.1:8000/paravolcar5/default/list_problems_by_game/338978835>
2
- Game 338995915
<http://127.0.0.1:8000/paravolcar5/default/list_problems_by_game/338995915>
2
Thanks & regards, Jon.
