django-bot 9c19aff7c7 Refs #33476 -- Reformatted code with Black. 2022-02-07 20:37:05 +01:00
Mariusz Felisiak c5cd878382
Refs #33476 -- Refactored problematic code before reformatting by Black. 
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],
)

Simon Charette e3bde71676 Refs #32690 -- Altered lookups Query rhs alterations during initialization. 
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.

saeedblanchette d3d95d645f Refs #24121 -- Added __repr__() to Lookup. 2021-05-24 07:32:25 +02:00
Simon Charette 136ff592ad Fixed #32690 -- Fixed __in lookup crash when combining with filtered aggregates. 
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.

Regression in 3543129822.

Thanks James A. Munsch for the report.

Refs #32673 -- Fixed lookups crash when comparing against lookups on Oracle.

Simon Charette 170b006ce8 Fixed #32673 -- Fixed lookups crash when comparing against lookups on PostgreSQL. 
Regression in 3a505c70e7.

Nonlitteral right-hand-sides of lookups need to be wrapped in
parentheses to avoid operator precedence ambiguities.

Thanks Charles Lirsac for the detailed report.

Simon Charette bbf141bcdc Refs #27149 -- Fixed sql.Query identity. 
By making Query subclass BaseExpression in

identity based off _construct_args which is not appropriate.

David Smith e74b3d724e Bumped minimum isort version to 5.1.0. 
Fixed inner imports per isort 5.
isort 5.0.0 to 5.1.0 was unstable.

Simon Charette 1e38f1191d Fixed #30446 -- Resolved Value.output_field for stdlib types. 
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.

Support hyphens in iexact, contains, icontains, startswith, istartswith,
endswith and iendswith UUIDField filters on backends without UUID
datatype.

James Timmins 0719edcd5f Fixed #30771 -- Fixed exact lookup against queries with selected columns. 
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.

Refs #25367 -- Simplified OrderBy and Lookup by using Case() instead of RawSQL() on Oracle. 
Follow up to efa1908f66.
 2019-08-29 11:56:12 +02:00
Simon Charette efa1908f66 Refs #25367 -- Moved Oracle Exists() handling to contextual methods. 
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.

Simon Charette 4d1420947e Fixed #30494 -- Disabled __year lookup optimization for indirect values. 
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.

Simon Charette 9ae4362bec Refs #16187 -- Stopped compiling query compilers during lookup rhs processing. 
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.

Simon Charette eb4724a063 Reverted "Refs #20939 -- Moved subquery ordering clearing optimization to the __in lookup." 
This reverts commit e62ea0bb9c since it
