* Add missing `touch_all` delegation to relationRyuta Kamizono2019-04-052-1/+33
| | | | Follow up of #31513.
* Stash `left_joins` into `joins` to deduplicate redundant LEFT JOINRyuta Kamizono2019-04-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Originally the `JoinDependency` has the deduplication for eager loading (LEFT JOIN). This re-uses that deduplication for `left_joins`. And also, This makes left join order into part of joins, i.e.: Before: ``` association joins -> stash joins (eager loading, etc) -> string joins -> left joins ``` After: ``` association joins -> stash joins (eager loading, left joins, etc) -> string joins ``` Now string joins are able to refer left joins. Fixes #34325. Fixes #34332. Fixes #34536.
* Revert unused code and re-using query annotation for `update_all` and ↵Ryuta Kamizono2019-04-012-46/+0
| | | | | | | | | | | | | | | | `delete_all` This partly reverts #35617. #35617 includes unused code (for `InsertStatement`) and re-using query annotation for `update_all` and `delete_all`, which has not been discussed yet. If a relation has any annotation, I think it is mostly for SELECT query, so re-using annotation by default is not always desired behavior for me. We should discuss about desired behavior before publishing the implementation.
* Add Relation#annotate for SQL commentingMatt Yoho2019-03-213-0/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch has two main portions: 1. Add SQL comment support to Arel via Arel::Nodes::Comment. 2. Implement a Relation#annotate method on top of that. == Adding SQL comment support Adds a new Arel::Nodes::Comment node that represents an optional SQL comment and teachers the relevant visitors how to handle it. Comment nodes may be added to the basic CRUD statement nodes and set through any of the four (Select|Insert|Update|Delete)Manager objects. For example: manager = Arel::UpdateManager.new manager.table table manager.comment("annotation") manager.to_sql # UPDATE "users" /* annotation */ This new node type will be used by ActiveRecord::Relation to enable query annotation via SQL comments. == Implementing the Relation#annotate method Implements `ActiveRecord::Relation#annotate`, which accepts a comment string that will be appeneded to any queries generated by the relation. Some examples: relation = Post.where(id: 123).annotate("metadata string") relation.first # SELECT "posts".* FROM "posts" WHERE "posts"."id" = 123 # LIMIT 1 /* metadata string */ class Tag < ActiveRecord::Base scope :foo_annotated, -> { annotate("foo") } end Tag.foo_annotated.annotate("bar").first # SELECT "tags".* FROM "tags" LIMIT 1 /* foo */ /* bar */ Also wires up the plumbing so this works with `#update_all` and `#delete_all` as well. This feature is useful for instrumentation and general analysis of queries generated at runtime.
* Delegate `only` query method to relation as with `except`Ryuta Kamizono2019-03-071-1/+1
| | | | | | | | | | | I've found the skewness of delegation methods between `except` and `only` in a88b6f2. The `only` method is closely similar with `except` as `SpawnMethods`. https://github.com/rails/rails/blob/e056b9bfb07c4eb3bcc6672d885aadd72bec574f/activerecord/lib/active_record/relation/spawn_methods.rb#L53-L67 It is preferable both behaves the same way.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a follow-up of #35310. Currently `Topic.find_by(id: "not-a-number")` matches to a `id = 0` record.

* | | All of queries should return correct result even if including large numberRyuta Kamizono2019-01-182-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently several queries cannot return correct result due to incorrect `RangeError` handling. First example: ```ruby assert_equal true, Topic.where(id: [1, 9223372036854775808]).exists? assert_equal true, Topic.where.not(id: 9223372036854775808).exists? ``` The first example is obviously to be true, but currently it returns false. Second example: ```ruby assert_equal topics(:first), Topic.where(id: 1..9223372036854775808).find(1) ``` The second example also should return the object, but currently it raises `RecordNotFound`. It can be seen from the examples, the queries including large number assuming empty result is not always correct. Therefore, This change handles `RangeError` to generate executable SQL instead of raising `RangeError` to users to always return correct result. By this change, it is no longer raised `RangeError` to users.

* | | Enable `Style/RedundantBegin` cop to avoid newly adding redundant begin blockRyuta Kamizono2018-12-211-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

|/ | | | | | | | | | | | | | | The `Relation::Merger` has a problem that order values would be merged as nested array. That was caused an issue #33664 since if array value is passed to `order` and first element in the array includes `?`, the array is regarded as a prepared statement and bind variables. https://api.rubyonrails.org/classes/ActiveRecord/Sanitization/ClassMethods.html#method-i-sanitize_sql_for_order Just merging that as splat args like other values would fix the issue. Fixes #33664.

This uses klass.arel_table and klass.predicate_builder as the defaults, so we don't have to pass them in most cases. This does change the signaure of both Relation and AssocationRelation. Are we ok with that?

| | | | | | | | | | | | | | | | | | | | `:authors` has a foreign key to `:author_addresses`. If only `:authors` fixture loaded into the database which supports foreign key and checks the existing data when enabling foreien keys like Oracle, it raises the following error `ORA-02298: cannot validate (ARUNIT.FK_RAILS_94423A17A3) - parent keys not found` It is because there is no parent data exists in `author_addresses` table. Here are how other database with foreign key support works: - MySQL does not check the existing data when enabling foreign key by `foreign_key_checks=1` https://dev.mysql.com/doc/refman/5.7/en/server-system-variables.html#sysvar_foreign_key_checks > Setting foreign_key_checks to 1 does not trigger a scan of the existing table data. Therefore, rows added to the table while foreign_key_checks=0 will not be verified for consistency. - PostgreSQL database itself has a feature to check existing data when enabling foreign key and discussed at #27636, which is reverted.
