Comment (by felixxm):
I prepared patch to reorganize database functions docs and code
([https://github.com/django/django/pull/9227 PR]). I think we should
organize code and doc as follows (bolded functions doesn't exist):
- `docs/ref/models/database-functions.txt` main section
(`django/db/models/functions/misc.py`):
- ''**Ascii**, Cast, **Chr**, Coalesce, Greatest, Least, Now'';
- `docs/ref/models/database-functions.txt` section `Date Functions`
(`django/db/models/functions/datetime.py`):
- ''Extract, ExtractDay, ExtractHour, ExtractMinute, ExtractMonth,
ExtractQuarter, ExtractSecond, ExtractWeek, ExtractWeekDay, ExtractYear,
Trunc, TruncDate, TruncDay, TruncHour, TruncMinute, TruncMonth,
TruncQuarter, TruncSecond, TruncTime, TruncYear;';
- `docs/ref/models/database-functions.txt` section `Math Functions`
(`django/db/models/functions/math.py`):
- ''**Abs**, **Acos**, **Asin**, **Atan**, **Atan2**, **Ceil**, **Cos**,
**Cot**, **Exp**, **Floor**, **Log**, **Mod**, **Sin**, **Sqrt**,
**Tan**'';
- `docs/ref/models/database-functions.txt` section `Text Functions`
(`django/db/models/functions/text.py`):
- ''Concat, ConcatPair, Length, **Lpad**, Lower, **Ltrim**, **Power**,
**Replace**, **Round**, **Rpad**, **Rtrim**, StrIndex, Substr, **Trim**,
Upper'';
- `docs/ref/models/database-functions.txt` section `Window Functions`
(`django/db/models/functions/window.py`):
- ''CumeDist, DenseRank, FirstValue, Lag, LastValue, Lead, NthValue,
Ntile, PercentRank, Rank, RowNumber''.
Headers and functions in docs and code should be organized alphabetically.
Thanks Tim Graham for suggestions.
I'm not convince that following functions should be implemented because
there not supported on all databases:
- LEFT(), MD5(), REPEAT(), REVERSE(), RIGHT(), DEGREES(), PI(), RADIANS().
