| * Avoid to handle polymorphic association for `AssociationQueryHandler`Ryuta Kamizono2017-03-282-29/+21
| | | | | | | | It should be handled by `PolymorphicArrayHandler` if polymorphic association.
* | Extract `construct_relation_for_exists` in `FinderMethods`Ryuta Kamizono2017-04-091-12/+15
| | | | | | | | To ease to customize a relation for `exists?`.

| | | | | | | | | | | | | | | | This reverts commit a680a5814184e2f37c4686aa53d0ad3c7fb6b1ee, reversing changes made to 842f67dd242e738419f27e752ea7dcd0bbe87b6d. Reason: I can't resist to the joke, so better to keep it there https://github.com/rails/rails/pull/28598#issuecomment-290945339.

|/ | | | | | | silly method gets a silly doc fix, or I'm missing an even sillier joke and I'm about to get schooled. BUT I'm pretty sure this is some serious Beaudrillard simulacrum, though. I'm just doing my part to spread the gospel of Douglas Adams.

|\ | | | | Preprocess association query handling in predicate builder
| * Always need to extract `value.bound_attributes` if `value.is_a?(Relation)`Ryuta Kamizono2017-03-251-3/+1
| | | | | | | | Because `RelationHandler` uses `value.arel`.
| * Preprocess association query handling in predicate builderRyuta Kamizono2017-03-201-11/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently association query is handled as a postprocess. This has two problems. 1. When `value` is a `Hash`, we need to skip the postprocess using `next`. 2. `can_be_bound?` should return false if `table.associated_with?(column_name)` is true (pass to the postprocess). These are unneeded if preprocessing association query handling.
* | Fix where_clause#except with specific where valueJohn Hawthorn2017-03-201-2/+2
| | | | | | | | | | | | | | | | | | Fixes a regression introduced in 22ca710f20c3c656811df006cbf1f4dbc359f7a6 where Relation#unscope with a specific where value (vs unscoping the entire where clause) could result in the wrong binds being left on the query. This was caused by an index variable not being incremented properly.
* | Use `load` rather than `collect` for force loadingRyuta Kamizono2017-03-191-1/+1
|/ | | | | | | Since b644964b `ActiveRecord::Relation` includes `Enumerable` so delegating `collect`, `all?`, and `include?` are also unneeded. `collect` without block returns `Enumerable` without preloading by that. We should use `load` rather than `collect` for force loading.
* Delegate `uniq` to `records`Ryuta Kamizono2017-03-181-1/+1
| | | | | | | | | | This fixes CI failure due to 48f3be8c. `Enumerable#uniq` was introduced since Ruby 2.4. We should delegate `uniq` to `records` explicitly. And since b644964b `ActiveRecord::Relation` includes `Enumerable` so delegating `map` is unneeded.

|\ | | | | Allow order to be given expressions as hash keys
| * Allow order to be given expressions as hash keysEugene Kenny2017-02-271-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | When `order` is given a hash, the keys are currently assumed to be attribute names and are quoted as such in the query, which makes it impossible to pass an expression instead: Post.order("LENGTH(title)" => :asc).last # SELECT `posts`.* FROM `posts` ORDER BY `posts`.`LENGTH(title)` DESC LIMIT 1 If the key is an `Arel::Nodes::SqlLiteral`, we now use it directly in the query. This provides a way to build a relation with a complex order clause that can still be reversed with `reverse_order` or `last`.

| * | Simply forward `Calculations#count` to `Enumerable#count`Ryuta Kamizono2017-03-101-7/+4
| | | | | | | | | | | | | | | | | | | | | Follow up of #24203. Since b644964b `ActiveRecord::Relation` includes `Enumerable` so it is enough to call `super` simply.

* | Include selects in group query with having clauseEugene Kenny2017-02-261-0/+1
|/ | | | | | | | | | | | | | When a grouped calculation contains a having clause that references a selected value, we need to include that selected value in the query. Postgres doesn't support referencing a selected value in a having clause, but other databases do; we can skip the test on the pg adapter but run it for the others. This was fixed before in 9a298a162c16e019fe6971e563e7f4916e86ced6, but the test coverage was lost in 5a05207d99b7e2678f9b42db2d9ffc21ec2c8c3b. The fix regressed in 6311975fb3c02f50730fd1e11b8dba8dd9c05306 and was removed in 97d46c17ea9113b0ce970167f5208c8d9170915c.

* Suppress `DISTINCT` clause outside aggregate functionRyuta Kamizono2017-02-251-2/+2
| | | | | | | | | | | | | | | | | | `DISTINCT` clause is applied inside aggregate function by `operation_over_aggregate_column` if needed. Unneeded outside aggregate function. ```ruby # Before author.unique_categorized_posts.count # => SELECT DISTINCT COUNT(DISTINCT "posts"."id") FROM "posts" INNER JOIN "categorizations" ON "posts"."id" = "categorizations"."post_id" WHERE "categorizations"."author_id" = ? [["author_id", 2]] # After author.unique_categorized_posts.count # => SELECT COUNT(DISTINCT "posts"."id") FROM "posts" INNER JOIN "categorizations" ON "posts"."id" = "categorizations"."post_id" WHERE "categorizations"."author_id" = ?
