[bug] [orm] Fixed bug where the ORM annotations could be incorrect for the
primaryjoin/secondaryjoin a relationship if one used the pattern
ForeignKey(SomeClass.id)
in the declarative mappings. This pattern
would leak undesired annotations into the join conditions which can break
aliasing operations done withinQuery
that are not supposed to
impact elements in that join condition. These annotations are now removed
up front if present.References: #4367
-
[bug] [declarative] [orm] A warning is emitted in the case that a
column()
object is applied to
a declarative class, as it seems likely this intended to be a
Column
object.References: #4374
-
[bug] [orm] In continuing with a similar theme as that of very recent #4349,
repaired issue withRelationshipProperty.Comparator.any()
and
RelationshipProperty.Comparator.has()
where the "secondary"
selectable needs to be explicitly part of the FROM clause in the
EXISTS subquery to suit the case where this "secondary" is aJoin
object.References: #4366
-
[bug] [orm] Fixed regression caused by #4349 where adding the "secondary"
table to the FROM clause for a dynamic loader would affect the ability of
theQuery
to make a subsequent join to another entity. The fix
adds the primary entity as the first element of the FROM list since
Query.join()
wants to jump from that. Version 1.3 will have
a more comprehensive solution to this problem as well (#4365).References: #4363
-
[bug] [orm] Fixed bug where chaining of mapper options using
RelationshipProperty.of_type()
in conjunction with a chained option
that refers to an attribute name by string only would fail to locate the
attribute. -
Added support for the
write_timeout
flag accepted by mysqlclient and
pymysql to be passed in the URL string.References: #4381
-
Fixed issue where reflection of a PostgreSQL domain that is expressed as an
array would fail to be recognized. Pull request courtesy Jakub Synowiec.
