Comment (by cuppett):
Okay. Have testcase. Thanks for the pointers today![[BR]]
[[BR]]
The problem seems to be database specific. Postgres exhibits the problem,
MySQL does not. I do not know about other engines.[[BR]]
[[BR]]
Using MySQL, the test passes and I see this:[[BR]]
[[BR]]
Query #12: DELETE `PostsTag` FROM `posts_tags` AS `PostsTag` WHERE
`PostsTag`.`tag_id` = '1' AND `PostsTag`.`post_id` IN (1, 2)[[BR]]
[[BR]]
Query #17: DELETE `PostsTag` FROM `posts_tags` AS `PostsTag` WHERE
`PostsTag`.`post_id` = 2 AND `PostsTag`.`tag_id` = ('3')[[BR]]
[[BR]]
Using PostgreSQL, the test fails. I get the following (unrelated?)
error:[[BR]]
[[BR]]
Query #19: SELECT "Tag"."id" AS "Tag__id", "Tag"."tag" AS "Tag__tag",
"Tag"."created" AS "Tag__created", "Tag"."updated" AS "Tag__updated",
"PostsTag"."post_id" AS "PostsTag__post_id", "PostsTag"."tag_id" AS
"PostsTag__tag_id" FROM "tags" AS "Tag" JOIN "posts_tags" AS "PostsTag" ON
("PostsTag"."post_id" = '1' AND "PostsTag"."tag_id" = "Tag"."id") WHERE 1
= 1[[BR]]
[[BR]]
Error: ERROR: operator does not exist: character varying = integer LINE 1:
...PostsTag"."post_id" = '1' AND "PostsTag"."tag_id" = "Tag"."i... ^ HINT:
No operator matches the given name and argument type(s). You might need to
add explicit type casts.[[BR]]
[[BR]]
And the problematic query:[[BR]]
[[BR]]
Query #24: DELETE FROM "posts_tags" WHERE "post_id" IN ('1', '2')[[BR]]
[[BR]]
I'm unsure about the second save's results as the first eliminates extra
rows that makes the second DELETE query unnecessary on ->save().[[BR]]
[[BR]]
I've attached the testcase. Also, I will apply my patch and post back
with those results for MySQL and PostgreSQL.
