From 5fb0138a3220161703e6ab1087319a669d14e7f4 Mon Sep 17 00:00:00 2001 From: Mike Bayer Date: Sat, 4 Jul 2020 12:21:36 -0400 Subject: Implement rudimentary asyncio support w/ asyncpg Using the approach introduced at https://gist.github.com/zzzeek/6287e28054d3baddc07fa21a7227904e We can now create asyncio endpoints that are then handled in "implicit IO" form within the majority of the Core internals. Then coroutines are re-exposed at the point at which we call into asyncpg methods. Patch includes: * asyncpg dialect * asyncio package * engine, result, ORM session classes * new test fixtures, tests * some work with pep-484 and a short plugin for the pyannotate package, which seems to have so-so results Change-Id: Idbcc0eff72c4cad572914acdd6f40ddb1aef1a7d Fixes: #3414 --- lib/sqlalchemy/dialects/postgresql/base.py | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'lib/sqlalchemy/dialects/postgresql/base.py') diff --git a/lib/sqlalchemy/dialects/postgresql/base.py b/lib/sqlalchemy/dialects/postgresql/base.py index 3bd7e62d5..7717a2526 100644 --- a/lib/sqlalchemy/dialects/postgresql/base.py +++ b/lib/sqlalchemy/dialects/postgresql/base.py @@ -1299,6 +1299,14 @@ class UUID(sqltypes.TypeEngine): """ self.as_uuid = as_uuid + def coerce_compared_value(self, op, value): + """See :meth:`.TypeEngine.coerce_compared_value` for a description.""" + + if isinstance(value, util.string_types): + return self + else: + return super(UUID, self).coerce_compared_value(op, value) + def bind_processor(self, dialect): if self.as_uuid: -- cgit v1.2.1
