* Ensure `StatementCache#execute` never raises `RangeError`Ryuta Kamizono2019-01-182-7/+13
| | | | | | | | | | | | | Since 31ffbf8d, finder methods no longer raise `RangeError`. So `StatementCache#execute` is the only place to raise the exception for finder queries. `StatementCache` is used for simple equality queries in the codebase. This means that if `StatementCache#execute` raises `RangeError`, the result could always be regarded as empty. So `StatementCache#execute` just return nil in that range error case, and treat that as empty in the caller side, then we can avoid catching the exception in much places.
* Refs #28025 nullify *_type column on polymorphic associations on :nu… ↵Laerti2019-01-152-0/+34
| | | | | | (#28078) This PR addresses the issue described in #28025. On `dependent: :nullify` strategy only the foreign key of the relation is nullified. However on polymorphic associations the `*_type` column is not nullified leaving the record with a NULL `*_id` but the `*_type` column is present.

* Enable `Style/RedundantBegin` cop to avoid newly adding redundant begin blockRyuta Kamizono2018-12-212-37/+31
| | | | | | | | | | Currently we sometimes find a redundant begin block in code review (e.g. https://github.com/rails/rails/pull/33604#discussion_r209784205). I'd like to enable `Style/RedundantBegin` cop to avoid that, since rescue/else/ensure are allowed inside do/end blocks in Ruby 2.5 (https://bugs.ruby-lang.org/issues/12906), so we'd probably meets with that situation than before.

| | | | | | | | | | | | | | Unlike the `Relation#delete_all`, `delete_all` on collection proxy doesn't return affected count. Since the `CollectionProxy` is a subclass of the `Relation`, this inconsistency is probably not intended, so it should return the count consistently.

* Fix handling of duplicates for `replace` on has_many-throughFlorian Ebeling2018-11-061-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There was a bug in the handling of duplicates when assigning (replacing) associated records, which made the result dependent on whether a given record was associated already before being assigned anew. E.g. post.people = [person, person] post.people.count # => 2 while post.people = [person] post.people = [person, person] post.people.count # => 1 This change adds a test to provoke the former incorrect behavior, and fixes it. Cause of the bug was the handling of record collections as sets, and using `-` (difference) and `&` (union) operations on them indiscriminately. This temporary conversion to sets would eliminate duplicates. The fix is to decorate record collections for these operations, and only for the `has_many :through` case. It is done by counting occurrences, and use the record together with the occurrence number as element, in order to make them work well in sets. Given a, b = *Person.all then the collection used for finding the difference or union of records would be internally changed from [a, b, a] to [[a, 1], [b, 1], [a, 2]] for these operations. So a first occurrence and a second occurrence would be distinguishable, which is all that is necessary for this task. Fixes #33942.
* Partly revert #31819bogdanvlviv2018-10-261-26/+0
| | | | | | | | | The PR#31819 changed `#preloaders_on` and added some test, then #33938 reverted changes that were added to the method in #31819. Since changes in the method were reverted and as mentioned in the comment https://github.com/rails/rails/pull/31819#discussion_r221847481 that titles of the tests added in #31819 don't reflect implementation I think we can remove those test for now.
* Lazy checking whether or not values in IN clause are boundableRyuta Kamizono2018-10-241-1/+1
| | | | | | | | | | | | | Since #33844, eager loading/preloading with too many and/or too large ids won't be broken by pre-checking whether the value is constructable or not. But the pre-checking caused the type to be evaluated at relation build time instead of at the query execution time, that is breaking an expectation for some apps. I've made the pre-cheking lazy as much as possible, that is no longer happend at relation build time.
* Add regression test against habtm memoized singular_idsAlberto Almagro2018-10-161-0/+12
| | | | | | | | | | | | | | | Starting in Rails 5.0.0 and still present in Rails 5.2.1, `singular_ids` got memoized and didn't reload after more items were added to the relation. Although 19c8071 happens to fix the issue, it only adds tests for `has_many` relations while this bug only affected `has_and_belongs_to_many` relations. This commit adds a regression test to ensure it never happens again with `habtm` relations. Ensures #34179 never gets reproduced.
* Ensure to test that `project.developers` is ordered by `developers.name desc`Ryuta Kamizono2018-10-151-1/+1
| | | | | | | | | `developers.name desc` was added at d59f3a7, but any test case isn't failed even if the `developers.name desc` is removed since all tested developers are consistently ordered on both `name` and `id`. I changed one developers creation ordering to ensure to test that `project.developers` is ordered by `developers.name desc`.

| * Generate delegation methods to named scope in the definition timeRyuta Kamizono2018-10-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The delegation methods to named scope are defined when `method_missing` is invoked on the relation. Since #29301, the receiver in the named scope is changed to the relation like others (e.g. `default_scope`, etc) for consistency. Most named scopes would be delegated from relation by `method_missing`, since we don't allow scopes to be defined which conflict with instance methods on `Relation` (#31179). But if a named scope is defined with the same name as any method on the `superclass` (e.g. `Kernel.open`), the `method_missing` on the relation is not invoked. To address the issue, make the delegation methods to named scope is generated in the definition time. Fixes #34098.

* | Fix `AssociationRelation` not to set inverse instance key just like beforeRyuta Kamizono2018-10-071-0/+12
|/ | | | | | | | | | | | | | | | | Since #31575, `set_inverse_instance` replaces the foreign key by the current owner immediately to make it happen when a record is added to collection association. But `set_inverse_instance` is not only called when a record is added, but also when a record is loaded from queries. And also, that loaded records are not always associated records for some reason (using `or`, `unscope`, `rewhere`, etc). It is hard to distinguish whether or not we should invoke `set_inverse_instance`, but at least we should avoid the undesired side-effect which was brought from #31575. Fixes #34108.

| | | | | | | | | `test_update_does_not_run_sql_if_record_has_not_changed` would pass without #18501 since `assert_queries` ignores BEGIN/COMMIT unless `ignore_none: true` is given. Since #32647, empty BEGIN/COMMIT is ommited. So we no longer need to use `assert_queries(0)` to ignore BEGIN/COMMIT in the queries.

* Don't update counter cache unless the record is actually savedRyuta Kamizono2018-09-191-6/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a 4th attempt to make counter cache transactional completely. Past attempts: #9236, #14849, #23357. All existing counter cache issues (increment/decrement twice, lost increment) are caused due to updating counter cache on the outside of the record saving transaction by assigning belongs_to record, even though assigning that doesn't cause the record saving. We have the `@_after_replace_counter_called` guard condition to mitigate double increment/decrement issues, but we can't completely prevent that inconsistency as long as updating counter cache on the outside of the transaction, since saving the record is not always happened after that. We already have handling counter cache after create/update/destroy, https://github.com/rails/rails/blob/1b90f614b1b3d06b7f02a8b9ea6cd84f15d58643/activerecord/lib/active_record/counter_cache.rb#L162-L189 https://github.com/rails/rails/blob/1b90f614b1b3d06b7f02a8b9ea6cd84f15d58643/activerecord/lib/active_record/associations/builder/belongs_to.rb#L33-L59 so just removing assigning logic on the belongs_to association makes counter cache transactional completely. Closes #14849. Closes #23357. Closes #31493. Closes #31494. Closes #32372. Closes #33113. Closes #33117 Closes #33129. Closes #33458.

| | | | | | | | | `topic` and `reply` belongs_to associations on `SillyReply` are defined with the same `foreign_key` (`parent_id`) and `counter_cache` (`replies_count`) columns. This would cause unintentional side-effect (e.g. saving `SillyReply` object would cause double increment `replies_count`), so it is better to avoid that side-effect.

* Eager loading/preloading should be worked regardless of large number of recordsRyuta Kamizono2018-09-121-0/+13
| | | | | | | | | | | | | | | | Since 213796f, bind params are used for IN clause if enabled prepared statements. Unfortunately, most adapter modules have a limitation for # of bind params (mysql2 65535, pg 65535, sqlite3 250000). So if eager loading large number of records at once, that query couldn't be sent to the database. Since eager loading/preloading queries are auto-generated by Active Record itself, so it should be worked regardless of large number of records like as before. Fixes #33702.

| | | | | | | | | | | | | | | | Previously ActiveRecord couldn't find inverse associations if they were plural, which is a pretty standard use case. This commit changes the behavior to first attempt to find the singular version, then attempt to find the plural version. That makes it work and find plural associations as in the example below: ``` class Post has_many :comments end class Comment belongs_to :post end ``` Previously the `:post` association reflection would only attempt to find a `comment` inverse, as opposed to both a `comment` and `comments` inverse.

For example, if we replace ``` ActiveRecord::Associations::HasManyAssociation .any_instance .expects(:reader) .never ``` with `assert_not_called`, Minitest wisely raises ``` NameError: undefined method `reader' for class `ActiveRecord::Associations::HasManyAssociation' ``` as `:reader` comes from a deeply embedded abstract class, `ActiveRecord::Associations::CollectionAssociation`. This patch tackles this difficulty by adding `ActiveSupport::Testing::MethodCallAsserts#assert_called_on_instance_of` which injects a stubbed method into `klass`, and verifies the number of times it is called, similar to `assert_called`. It also adds a convenience method, `assert_not_called_on_instance_of`, mirroring `assert_not_called`. It uses the new method_call_assertions to replace the remaining Mocha calls in `ActiveRecord` tests. [utilum + bogdanvlviv + kspath]

|/ | | | | | | | | | | | | | | | | | | | Since fe9547b6, numericality validator would parse raw value only when a value came from user to work type casting to a value from database. But that was caused a regression that the validator would work against getter value instead of parsed raw value, a getter is sometimes customized by people. #33550 There we never guarantees that the value before type cast was going to the used in this validation (actually here is only place that getter value might not be used), but we should not change the behavior unless there is some particular reason. The purpose of fe9547b6 is to work type casting to a value from database. We could achieve the purpose by using `read_attribute`, without using getter value. Fixes #33550.

| | | | | | | | | | | | | | | | | Currently, column aliases which is used for eager loading are calculated before constructing all table aliases in FROM clause. `JoinDependency#join_constraints` constructs table aliases for `joins` first, and then always re-constructs table aliases for eager loading. If both `joins` and eager loading are given a same table association, the re-construction would cause the discrepancy between column aliases and table aliases. To avoid the discrepancy, the column aliases should be calculated after all table aliases are constructed. Fixes #30603.
