* Only nullify persisted has_one target associationsAgis-2015-08-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Since after 87d1aba3c `dependent: :destroy` callbacks on has_one assocations run *after* destroy, it is possible that a nullification is attempted on an already destroyed target: class Car < ActiveRecord::Base has_one :engine, dependent: :nullify end class Engine < ActiveRecord::Base belongs_to :car, dependent: :destroy end > car = Car.create! > engine = Engine.create!(car: car) > engine.destroy! # => ActiveRecord::ActiveRecordError: cannot update a > destroyed record In the above case, `engine.destroy!` deletes `engine` and *then* triggers the deletion of `car`, which in turn triggers a nullification of `engine.car_id`. However, `engine` is already destroyed at that point. Fixes #21223.

* | Fix counter_cache for polymorphic associationsStefan Kanev2015-07-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Also removes a false positive test that depends on the fixed bug: At this time, counter_cache does not work with polymorphic relationships (which is a bug). The test was added to make sure that no StaleObjectError is raised when the car is destroyed. No such error is currently raised because the lock version is not incremented by appending a wheel to the car. Furthermore, `assert_difference` succeeds because `car.wheels.count` does not check the counter cache, but the collection size. The test will fail if it is replaced with `car.wheels_count || 0`.
* | Ensure cyclic associations w/ autosave don't cause duplicate errorsSean Griffin2015-07-181-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This code is so fucked. Things that cause this bug not to replicate: - Defining the validation before the association (we end up calling `uniq!` on the errors in the autosave validation) - Adding `accepts_nested_attributes_for` (I have no clue why. The only thing it does that should affect this is adds `autosave: true` to the inverse reflection, and doing that manually doesn't fix this). This solution is a hack, and I'm almost certain there's a better way to go about it, but this shouldn't cause a huge hit on validation times, and is the simplest way to get it done. Fixes #20874.

* Fix leaky chain on polymorphic associationeileencodes2015-03-151-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If there was a polymorphic hm:t association with a scope AND second non-scoped hm:t association on a model the polymorphic scope would leak through into the call for the non-polymorhic hm:t association. This would only break if `hotel.drink_designers` was called before `hotel.recipes`. If `hotel.recipes` was called first there would be no problem with the SQL. Before (employable_type should not be here): ``` SELECT COUNT(*) FROM "drink_designers" INNER JOIN "chefs" ON "drink_designers"."id" = "chefs"."employable_id" INNER JOIN "departments" ON "chefs"."department_id" = "departments"."id" WHERE "departments"."hotel_id" = ? AND "chefs"."employable_type" = ? [["hotel_id", 1], ["employable_type", "DrinkDesigner"]] ``` After: ``` SELECT COUNT(*) FROM "recipes" INNER JOIN "chefs" ON "recipes"."chef_id" = "chefs"."id" INNER JOIN "departments" ON "chefs"."department_id" = "departments"."id" WHERE "departments"."hotel_id" = ? [["hotel_id", 1]] ``` From the SQL you can see that `employable_type` was leaking through when calling recipes. The solution is to dup the chain of the polymorphic association so it doesn't get cached. Additionally, this follows `scope_chain` which dup's the `source_reflection`'s `scope_chain`. This required another model/table/relationship because the leak only happens on a hm:t polymorphic that's called before another hm:t on the same model. I am specifically testing the SQL here instead of the number of records becasue the test could pass if there was 1 drink designer recipe for the drink designer chef even though the `employable_type` was leaking through. This needs to specifically check that `employable_type` is not in the SQL statement.

* | Use bind values for joined tables in where statementsSean Griffin2014-11-011-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In practical terms, this allows serialized columns and tz aware columns to be used in wheres that go through joins, where they previously would not behave correctly. Internally, this removes 1/3 of the cases where we rely on Arel to perform type casting for us. There were two non-obvious changes required for this. `update_all` on relation was merging its bind values with arel's in the wrong order. Additionally, through associations were assuming there would be no bind parameters in the preloader (presumably because the where would always be part of a join) [Melanie Gilman & Sean Griffin]

* Deprecate automatic counter caches on has_many :throughSean Griffin2014-06-261-2/+1
| | | | | | | | | | | 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.

|/ | | | | | | | | | | | | | | | | | | | | | | | As a result of all of the refactoring that's been done, it's now possible for us to define a public API to allow users to specify behavior. This is an initial implementation so that I can work off of it in smaller pieces for additional features/refactorings. The current behavior will continue to stay the same, though I'd like to refactor towards the automatic schema detection being built off of this API, and add the ability to opt out of automatic schema detection. Use cases: - We can deprecate a lot of the edge cases around types, now that there is an alternate path for users who wish to maintain the same behavior. - I intend to refactor serialized columns to be built on top of this API. - Gem and library maintainers are able to interact with `ActiveRecord` at a slightly lower level in a more stable way. - Interesting ability to reverse the work flow of adding to the schema. Model can become the single source of truth for the structure. We can compare that to what the database says the schema is, diff them, and generate a migration.
* Fixed serialization for records with an attribute named `format`.Godfrey Chan2014-05-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * * * This bug can be triggered when serializing record R (the instance) of type C (the class), provided that the following conditions are met: 1. The name of one or more columns/attributes on C/R matches an existing private method on C (e.g. those defined by `Kernel`, such as `format`). 2. The attribute methods have not yet been generated on C. In this case, the matching private methods will be called by the serialization code (with no arguments) and their return values will be serialized instead. If the method requires one or more arguments, it will result in an `ArgumentError`. This regression is introduced in d1316bb. * * * Attribute methods (e.g. `#name` and `#format`, assuming the class has columns named `name` and `format` in its database table) are lazily defined. Instead of defining them when a the class is defined (e.g. in the `inherited` hook on `ActiveRecord::Base`), this operation is deferred until they are first accessed. The reason behind this is that is defining those methods requires knowing what columns are defined on the database table, which usually requires a round-trip to the database. Deferring their definition until the last-possible moment helps reducing unnessary work, especially in development mode where classes are redefined and throw away between requests. Typically, when an attribute is first accessed (e.g. `a_book.format`), it will fire the `method_missing` hook on the class, which triggers the definition of the attribute methods. This even works for methods like `format`, because calling a private method with an explicit receiver will also trigger that hook. Unfortunately, `read_attribute_for_serialization` is simply an alias to `send`, which does not respect method visibility. As a result, when serializing a record with those conflicting attributes, the `method_missing` is not fired, and as a result the attribute methods are not defined one would expected. Before d1316bb, this is negated by the fact that calling the `run_callbacks` method will also trigger a call to `respond_to?`, which is another trigger point for the class to define its attribute methods. Therefore, when Active Record tries to run the `after_find` callbacks, it will also define all the attribute methods thus masking the problem. * * * The proper fix for this problem is probably to restrict `read_attribute_for_serialization` to call public methods only (i.e. alias `read_attribute_for_serialization` to `public_send` instead of `send`). This however would be quite risky to change in a patch release and would probably require a full deprecation cycle. Another approach would be to override `read_attribute_for_serialization` inside Active Record to force the definition of attribute methods: def read_attribute_for_serialization(attribute) self.class.define_attribute_methods send(attribute) end Unfortunately, this is quite likely going to cause a performance degradation. This patch therefore restores the behaviour from the 4-0-stable branch by explicitly forcing the class to define its attribute methods in a similar spot (when records are initialized). This should not cause any extra roundtrips to the database because the `@columns` should already be cached on the class. Fixes #15188.
