Support formulas inside select()
-
external.prepare
for Model and Property became Expr instead of dict. -
Expr now has it's own unparse and preserves exact expression representation.
-
Sql
backend now supports formulas inselect()
. -
count()
now must be insideselect()
, but only forSql
backend. -
Property.external
no longer can be a list, if you need more than one value, useprepare
.
