* Revert "Merge pull request #16400 from bogdan/last-with-sql"Sean Griffin2016-02-011-23/+9
| | | | | | | | | | This reverts commit 9f3730a516f30beb0050caea9539f8d6b808e58a, reversing changes made to 2637fb75d82e1c69333855abd58c2470994995d3. There are additional issues with this commit that need to be addressed before this change is ready (see #23377). This is a temporary revert in order for us to have more time to address the issues with that PR, without blocking the release of beta2.

This commit is to fix the test to NULL-agnostic way. Example: ``` activerecord_unittest=# SELECT DISTINCT "posts"."id", author_addresses_authors.id AS alias_0 FROM "posts" LEFT OUTER JOIN "authors" ON "authors"."id" = "posts"."author_id" LEFT OUTER JOIN "author_addresses" ON "author_addresses"."id" = "authors"."author_address_id" LEFT OUTER JOIN "categorizations" ON "categorizations"."category_id" = "posts"."id" LEFT OUTER JOIN "authors" "authors_posts" ON "authors_posts"."id" = "categorizations"."author_id" LEFT OUTER JOIN "author_addresses" "author_addresses_authors" ON "author_addresses_authors"."id" = "authors_posts"."author_address_id" ORDER BY author_addresses_authors.id DESC; id | alias_0 ----+--------- 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 1 | 1 (12 rows) ``` ``` root@localhost [activerecord_unittest] > SELECT DISTINCT `posts`.`id`, author_addresses_authors.id AS alias_0 FROM `posts` LEFT OUTER JOIN `authors` ON `authors`.`id` = `posts`.`author_id` LEFT OUTER JOIN `author_addresses` ON `author_addresses`.`id` = `authors`.`author_address_id` LEFT OUTER JOIN `categorizations` ON `categorizations`.`category_id` = `posts`.`id` LEFT OUTER JOIN `authors` `authors_posts` ON `authors_posts`.`id` = `categorizations`.`author_id` LEFT OUTER JOIN `author_addresses` `author_addresses_authors` ON `author_addresses_authors`.`id` = `authors_posts`.`author_address_id` ORDER BY author_addresses_authors.id DESC; +----+---------+ | id | alias_0 | +----+---------+ | 1 | 1 | | 3 | NULL | | 1 | NULL | | 2 | NULL | | 4 | NULL | | 5 | NULL | | 6 | NULL | | 7 | NULL | | 8 | NULL | | 9 | NULL | | 10 | NULL | | 11 | NULL | +----+---------+ 12 rows in set (0.00 sec) ```

| * Implement limit & offset for ourselvesMatthew Draper2015-12-181-2/+2
| | | | | | | | | | | | | | | | | | | | We know the query will return exactly one row for each entry in the `ids` array, so we can do all the limit/offset calculations on that array, in advance. I also split our new ordered-ids behaviour out of the existing `find_some` method: especially with this change, the conditionals were overwhelming the actual logic.

* | Use a bind param for `LIMIT` and `OFFSET`Sean Griffin2015-12-141-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently generate an unbounded number of prepared statements when `limit` or `offset` are called with a dynamic argument. This changes `LIMIT` and `OFFSET` to use bind params, eliminating the problem. `Type::Value#hash` needed to be implemented, as it turns out we busted the query cache if the type object used wasn't exactly the same object. This drops support for passing an `Arel::Nodes::SqlLiteral` to `limit`. Doing this relied on AR internals, and was never officially supported usage. Fixes #22250.

| | | | | | | | | | | | `replace_named_bind_variables` and `replace_bind_variables` are definded in `sanitization.rb`, so it is reasonable these tests are on `sanitize_test.rb`.

| | | | | | | | | | This ensures that we're handling all forms of nested tables the same way. We're aware that the `convert_dot_notation_to_hash` method will cause a performance hit, and we intend to come back to it once we've refactored some of the surrounding code. [Melissa Xie & Melanie Gilman]

* Treat strings greater than int max value as out of rangeSean Griffin2014-10-311-13/+14
| | | | | | | | | | | Sufficiently large integers cause `find` and `find_by` to raise `StatementInvalid` instead of `RecordNotFound` or just returning `nil`. Given that we can't cast to `nil` for `Integer` like we would with junk data for other types, we raise a `RangeError` instead, and rescue in places where it would be highly unexpected to get an exception from casting. Fixes #17380
* Fix find_by with associations not working with adequate recordGodfrey Chan2014-09-201-0/+5
| | | | | | | | | For now, we will just skip the cache when a non-column key is used in the hash. If the future, we can probably move some of the logic in PredicateBuilder.expand up the chain to make caching possible for association queries. Closes #16903 Fixes #16884

| | | | | | | | | | | | | | | | | | | | | | * Also duplicated find_by tests from relations_test.rb to finder_test.rb now that we have a completely different implementation on the class (in core.rb with AST caching stuff). * Also removed a (failing) test that used mocks. Now that we have tests for the behavior, there's no point having another test that tests the implementation (that it delegates). Further, what the test was implying is nolonger true with the current implementation, because Class.find_by is a real method now.

* | Deprecate automatic counter caches on has_many :throughSean Griffin2014-06-261-2/+2
| | | | | | | | | | | | | | | | | | | | | | Reliant on https://github.com/rails/rails/pull/15747 but pulled to a separate PR to reduce noise. `has_many :through` associations have the undocumented behavior of automatically detecting counter caches. However, the way in which it does so is inconsistent with counter caches everywhere else, and doesn't actually work consistently. As with normal `has_many` associations, the user should specify the counter cache on the `belongs_to`, if they'd like it updated.

* Make exists? use bound values.Martin Schürrer2014-03-041-2/+14
| | | | | | | | | | | When we build a query with an inline value that is a numeric (e.g. because it's out of range for an int4) PostgreSQL doesn't use an index on the column, since it's now comparing numerics and not int4s. This leads to a _very_ slow query. When we use bound parameters instead of inline values PostgreSQL raises numeric_value_out_of_range since no automatic coercion happens.

* Ensure AR #second, #third, etc. finders work through associationsJason Meller2014-01-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit fixes two regressions introduced in cafe31a078 where newly created finder methods #second, #third, #forth, and #fifth caused a NoMethodError error on reload associations and where we were pulling the wrong element out of cached associations. Examples: some_book.authors.reload.second # Before # => NoMethodError: undefined method 'first' for nil:NilClass # After # => #<Author id: 2, name: "Sally Second", ...> some_book.first.authors.first some_book.first.authors.second # Before # => #<Author id: 1, name: "Freddy First", ...> # => #<Author id: 1, name: "Freddy First", ...> # After # => #<Author id: 1, name: "Freddy First", ...> # => #<Author id: 2, name: "Sally Second", ...> Fixes #13783.
* Ensure #second acts like #first AR finderJason Meller2014-01-201-1/+89
| | | | | | | | | | | | This commit bring the famous ordinal Array instance methods defined in ActiveSupport into ActiveRecord as fully-fledged finders. These finders ensure a default ascending order of the table's primary key, and utilize the OFFSET SQL verb to locate the user's desired record. If an offset is defined in the query, calling #second adds to the offset to get the actual desired record. Fixes #13743.
