In these cases Black produces unexpected results, e.g.
def make_random_password(
self,
length=10,
allowed_chars='abcdefghjkmnpqrstuvwxyz' 'ABCDEFGHJKLMNPQRSTUVWXYZ' '23456789',
):
or
cursor.execute("""
SELECT ...
""",
[table name],
)
Having it happen at the lookup creation time ensures entry points
called before the compilation phase (e.g. get_group_by_cols) don't have
to duplicate the logic in charge of altering Query instances used as
rhs.
It also has the nice effect of reducing the amount of time the
alteration logic to once as opposed to multiple times if the queryset
is compiled more than once.
Having lookups group by subquery right-hand-sides is likely unnecessary
in the first place but relatively large amount of work would be needed
to achieve that such as making Lookup instances proper resolvable
expressions.

Thanks James A. Munsch for the report.

Nonlitteral right-hand-sides of lookups need to be wrapped in
parentheses to avoid operator precedence ambiguities.
Thanks Charles Lirsac for the detailed report.
This required implementing a limited form of dynamic dispatch to combine
expressions with numerical output. Refs #26355 should eventually provide
a better interface for that.
Use pre-existing select fields (and thereby GROUP BY fields) from
subquery if they were specified, instead of always defaulting to pk.
Thanks Aur Saraf for the report and Simon Charette for guidance.
Oracle requires the EXISTS expression to be wrapped in a CASE WHEN in
the following cases.
1. When part of a SELECT clause.
2. When part of a ORDER BY clause.
3. When compared against another expression in the WHERE clause.
This commit moves the systematic CASE WHEN wrapping of Exists.as_oracle
to contextual .select_format, Lookup.as_oracle, and OrderBy.as_oracle
methods in order to avoid unnecessary wrapping.
The previous heuristics were naively enabling the BETWEEN optimization on
successful cast of the first rhs SQL params to an integer while it was
not appropriate for a lot of database resolved expressions.
Thanks Alexey Chernov for the report.
Thanks Josh Smeaton, Mariusz Felisiak, Sergey Fedoseev, Simon Charettes,
Adam Chainz/Johnson and Tim Graham for comments and reviews and Jamie
Cockburn for initial patch.
Lookup right hand side processing was compiling query compilers which happened
to work by chance as SQLCompiler defines a as_sql() method with two optional
parameters albeit it doesn't expect the same type of arguments.
