Fixed #33464 -- Resolved output_field for combined numeric expressions with MOD operator. 2022-09-27 20:41:10 +02:00
Mariusz Felisiak 68da6b389c
Fixed #33543 -- Deprecated passing nulls_first/nulls_last=False to OrderBy and Expression.asc()/desc(). 
Thanks Allen Jonathan David for the initial patch.

Mariusz Felisiak 1760ad4e8c
Relaxed some query ordering assertions in various tests. 
It accounts for differences seen on MySQL with MyISAM storage engine.

Mariusz Felisiak 93cae5cb2f Fixed CVE-2022-28346 -- Protected QuerySet.annotate(), aggregate(), and extra() against SQL injection in column aliases. 
Thanks Splunk team: Preston Elder, Jacob Davis, Jacob Moore,
Matt Hanson, David Briggs, and a security researcher: Danylo Dmytriiev
(DDV_UA) for the report.

Luke Plant 40b8a6174f Fixed #33397 -- Corrected resolving output_field for DateField/DateTimeField/TimeField/DurationFields. 
This includes refactoring of CombinedExpression._resolve_output_field()
so it no longer uses the behavior inherited from Expression of guessing
same output type if argument types match, and instead we explicitly
define the output type of all supported operations.

This also makes nonsensical operations involving dates
(e.g. date + date) raise a FieldError, and adds support for
automatically inferring output_field for cases such as:
* date - date
* date + duration
* date - duration
* time + duration
* time - time

Mariusz Felisiak 7119f40c98 Refs #33476 -- Refactored code to strictly match 88 characters line length. 2022-02-07 20:37:05 +01:00

Regression in b7d1da5a62.

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],
)

My-Name-Is-Nabil f37face331 Fixed #33435 -- Fixed invalid SQL generatered by Subquery.as_sql(). 2022-01-17 09:00:46 +01:00
Allen Jonathan David 28c98d4113 Fixed #33216 -- Simpilified deconstructed paths for some expressions. 2022-01-07 11:19:29 +01:00
Keryn Knight 0ed2919814 Fixed #33406 -- Avoided creation of MaxLengthValidator(None) when resolving Value.output_field for strings. 
This brings the behaviour in line with Field subclasses which append to
the validators within __init__(), like BinaryField, and prevents the
creation of a validator which incorrectly throws a TypeError, if it
were used.
 2022-01-04 05:51:00 +01:00
Keryn Knight b894199eb0 Refs #33406 -- Added test for not creating broken validators when resolving Value.output_field. 2022-01-04 05:51:00 +01:00

Hasan Ramezani 3f7b327562 Fixed #31235 -- Made assertQuerysetEqual() compare querysets directly. 
This also replaces assertQuerysetEqual() to
assertSequenceEqual()/assertCountEqual() where appropriate.

Relaxed some query ordering assertions in expressions tests. 
It accounts for differences seen on CockroachDB.

Nick Pope 06c5d3fafc Fixed #32060 -- Added Random database function. 2020-10-02 06:58:03 +02:00
Simon Charette 38fce49c82 Fixed #31919 -- Resolved output_field of IntegerField subclasses combinations. 2020-08-31 06:42:40 +02:00
Simon Charette 40894f2967 Refs #30446 -- Added tests for resolving output_field of CombinedExpression. 2020-08-31 06:40:39 +02:00
Simon Charette 51297a9232 Fixed #31792 -- Made Exists() reuse QuerySet.exists() optimizations. 
The latter is already optimized to limit the number of results, avoid
selecting unnecessary fields, and drop ordering if possible without
altering the semantic of the query.
 2020-08-13 14:10:36 +02:00
Simon Charette 156a2138db Refs #30446 -- Removed unnecessary Value(..., output_field) in docs and tests. 2020-07-15 10:58:38 +02:00
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.
 2020-07-15 10:58:29 +02:00
Simon Charette f783a99072 Refs #25425 -- Allowed unresolved Value() instances to be compiled. 
Previously unresolved Value() instances were only allowed to be
compiled if they weren't initialized with an output_field.

Given the usage of unresolved Value() instances is relatively common in
as_sql() overrides it's less controversial to add explicit support for
this previously undefined behavior now and revisit whether or not it
should be deprecated in the future.
