* Add insert_all to ActiveRecord models (#35077)Bob Lail2019-03-051-0/+4
| | | | | Adds a method to ActiveRecord allowing records to be inserted in bulk without instantiating ActiveRecord models. This method supports options for handling uniqueness violations by skipping duplicate records or overwriting them in an UPSERT operation. ActiveRecord already supports bulk-update and bulk-destroy actions that execute SQL UPDATE and DELETE commands directly. It also supports bulk-read actions through `pluck`. It makes sense for it also to support bulk-creation.
* Deprecate mismatched collation comparison for uniquness validatorRyuta Kamizono2019-03-041-10/+17
| | | | | | | | | | | | | | | | | | | | | In MySQL, the default collation is case insensitive. Since the uniqueness validator enforces case sensitive comparison by default, it frequently causes mismatched collation issues (performance, weird behavior, etc) to MySQL users. https://grosser.it/2009/12/11/validates_uniqness_of-mysql-slow/ https://github.com/rails/rails/issues/1399 https://github.com/rails/rails/pull/13465 https://github.com/gitlabhq/gitlabhq/commit/c1dddf8c7d947691729f6d64a8ea768b5c915855 https://github.com/huginn/huginn/pull/1330#discussion_r55152573 I'd like to deprecate the implicit default enforcing since I frequently experienced the problems in code reviews. Note that this change has no effect to sqlite3, postgresql, and oracle-enhanced adapters which are implemented as case sensitive by default, only affect to mysql2 adapter (I can take a work if sqlserver adapter will support Rails 6.0).

* Fix `pluck` and `select` with custom attributesRyuta Kamizono2019-02-131-0/+1
| | | | | | | | | Currently custom attributes are always qualified by the table name in the generated SQL wrongly even if the table doesn't have the named column, it would cause an invalid SQL error. Custom attributes should only be qualified if the table has the same named column.

| | | | Use column definition with `primary_key: true` instead.
* Support expression indexes for MySQLRyuta Kamizono2018-10-251-1/+1
| | | | | | | MySQL 8.0.13 and higher supports functional key parts that index expression values rather than column or column prefix values. https://dev.mysql.com/doc/refman/8.0/en/create-index.html
* Lazy checking whether or not values in IN clause are boundableRyuta Kamizono2018-10-241-3/+3
| | | | | | | | | | | | | 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.
* Change the empty block style to have space inside of the blockRafael Mendonça França2018-09-251-1/+1

* Eager loading/preloading should be worked regardless of large number of recordsRyuta Kamizono2018-09-121-0/+1
| | | | | | | | | | | | | | | | 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.
* Fix `touch` option to behave consistently with `Persistence#touch` methodRyuta Kamizono2018-06-181-1/+3
| | | | | | | | | | | | | | | | `touch` option was added to `increment!` (#27660) and `update_counters` (#26995). But that option behaves inconsistently with `Persistence#touch` method. If `touch` option is passed attribute names, it won't update update_at/on attributes unlike `Persistence#touch` method. Due to changed from `Persistence#touch` to `increment!` with `touch` option, #31405 has a regression that `counter_cache` with `touch` option which is passed attribute names won't update update_at/on attributes. I think that the inconsistency is not intended. To get back consistency, ensure that `touch` option updates update_at/on attributes.

* Fix .new with multiple through associationsSam DeCesare2018-04-091-0/+13
| | | | | | | | | | | | | | | | | | | This fixes a bug with building an object that has multiple `has_many :through` associations through the same object. Previously, when building the object via .new, the intermediate object would be created instead of just being built. Here's an example: Given a GameBoard, that has_one Owner and Collection through Game. The following line would cause a game object to be created in the database. GameBoard.new(owner: some_owner, collection: some_collection) Whereas, if passing only one of those associations into `.new` would cause the Game object to be built and not created in the database. Now the above code will only build the Game object, and not save it.

* Add custom prefix to ActiveRecord::Store accessorsTan Huynh2018-03-231-0/+2
| | | | | | Add a prefix option to ActiveRecord::Store.store_accessor and ActiveRecord::Store.store. This option allows stores to have identical keys with different accessors.

* Make `reflection.klass` raise if `polymorphic?` not to be misusedRyuta Kamizono2018-02-191-0/+2
| | | | | | | | | | | | | | | | This is an alternative of #31877 to fix #31876 caused by #28808. This issue was caused by a combination of several loose implementation. * finding automatic inverse association of polymorphic without context (caused by #28808) * returning `klass` even if `polymorphic?` (exists before #28808) * loose verification by `valid_inverse_reflection?` (exists before #28808) This makes `klass` raise if `polymorphic?` not to be misused. This issue will not happen unless polymorphic `klass` is misused. Fixes #31876. Closes #31877.
* Don't update counter cache when through record was not destroyedEugene Kenny2018-01-141-0/+2
| | | | | | When removing a record from a has many through association, the counter cache was being updated even if the through record halted the callback chain and prevented itself from being destroyed.

* Use nullable `id` column instead of a primary keyRyuta Kamizono2017-06-161-1/+2

* Avoid overwriting the methods of `AttributeMethods::PrimaryKey`Ryuta Kamizono2017-06-071-6/+8
