* Load only needed records on ActiveRecord::Relation#inspectHendy Tanata2017-03-281-0/+6
| | | | | | | Instead of loading all records and returning only a subset of those, just load the records as needed. Fixes #25537.
* Use `SET CONSTRAINTS` for `disable_referential_integrity` without superuser ↵Fumiaki MATSUSHIMA2017-03-261-1/+1
| | | | | | | | | | | | | | | privileges (take 2) Re-create https://github.com/rails/rails/pull/21233 eeac6151a5 was reverted (127509c071b4) because it breaks tests. ---------------- ref: 72c1557254 - We must use `authors` fixture with `author_addresses` because of its foreign key constraint. - Tests require PostgreSQL >= 9.4.2 because it had a bug about `ALTER CONSTRAINTS` and fixed in 9.4.2.
* Fix where_clause#except with specific where valueJohn Hawthorn2017-03-201-0/+8
| | | | | | | | | 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 Kamizono2017-03-191-7/+7
| | | | | | | 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.
* Allow order to be given expressions as hash keysEugene Kenny2017-02-271-1/+24
| | | | | | | | | | | | | 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`.

* Respect new records for `CollectionProxy#uniq`Ryuta Kamizono2016-11-131-1/+0
| | | | | | | | | | | | | Currently if `CollectionProxy` has more than one new record, `CollectionProxy#uniq` result is incorrect. And `CollectionProxy#uniq` was aliased to `distinct` in a1bb6c8b06db. But the `uniq` method and the `SELECT DISTINCT` method are different methods. The doc in `CollectionProxy` is for the `SELECT DISTINCT` method, not for the `uniq` method. Therefore, reverting the alias in `CollectionProxy` to fix the inconsistency and to have the both methods.

* | Allow the connection adapters to determine the order of bind paramsSean Griffin2016-05-061-0/+18
|/ | | | | | | | | | | | In 5.0 we use bind parameters for limit and offset, while in 4.2 we used the values directly. The code as it was written assumed that limit and offset worked as `LIMIT ? OFFSET ?`. Both Oracle and SQL Server have a different syntax, where the offset is stated before the limit. We delegate this behavior to the connection adapter so that these adapters are able to determine how the bind parameters are flattened based on what order their specification has the various clauses appear.

These tests examine to sanitize `ORDER BY FIELD()` with empty data appropriately. ```ruby Tag.order(['field(id, ?)', []]).to_sql # => SELECT "tags".* FROM "tags" ORDER BY field(id, NULL) Tag.order(['field(id, ?)', nil]).to_sql # => SELECT "tags".* FROM "tags" ORDER BY field(id, NULL) ```

| * Fix `first(limit)` to take advantage of `loaded?` records if availableBen Woosley2015-12-241-3/+14
|/ | | | | | | | | | | | | | | | | I realized that `first(2)`, etc. was unnecessarily querying for the records when they were already preloaded. This was because `find_nth_with_limit` can not know which `@records` to return because it conflates the `offset` and `index` into a single variable, while the `@records` only needs the `index` itself to select the proper record. Because `find_nth` and `find_nth_with_limit` are public methods, I instead introduced a private method `find_nth_with_limit_and_offset` which is called internally and handles the `loaded?` checking. Once the `offset` argument is removed from `find_nth`, `find_nth_with_limit_and_offset` can be collapsed into `find_nth_with_limit`, with `offset` always equal to `offset_index`.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for sanitizing arrays in SQL ORDER clauses. This is useful when using MySQL `ORDER BY FIELD()` to return records in a predetermined way. ```ruby Tag.order(['field(id, ?', [1,3,2]].to_sql # => SELECT "tags".* FROM "tags" ORDER BY field(id, 1,3,2) ``` Prior to this, developers must be careful to sanitize `#order` arguments themselves.
* | Add deprecation warning to `ActiveRecord::Relation#update`Ted Johansson2015-10-151-0/+7
| | | | | | | | | | | | | | | | When passing an instance of `ActiveRecord::Base` to `#update`, it would internally call `#find`, resulting in a misleading deprecation warning. This change gives this deprecated use of `#update` its own, meaningful warning.

* | Fix regression caused by a01d164bRafael Mendonça França2015-07-071-0/+19
| | | | | | | | | | | | | | | | | | When preload is used in a default scope the preload_values were returning nested arrays and causing the preloader to fail because it doesn't know how to deal with nested arrays. So before calling preload! we need to splat the arguments. This is not needed to includes because it flatten its arguments.
