* | | | introduce `conn.data_source_exists?` and `conn.data_sources`.Yves Senn2015-09-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These new methods are used from the Active Record model layer to determine which relations are viable to back a model. These new methods allow us to change `conn.tables` in the future to only return tables and no views. Same for `conn.table_exists?`. The goal is to provide the following introspection methods on the connection: * `tables` * `table_exists?` * `views` * `view_exists?` * `data_sources` (views + tables) * `data_source_exists?` (views + tables)

However, `engine` is already destroyed at that point. Fixes #21223.

| * | | | Require explicit counter_cache option for has_manyTristan Gamilis2015-04-072-5/+5
| |/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously has_many associations assumed a counter_cache was to be used based on the presence of an appropriately named column. This is inconsistent, since the inverse belongs_to association will not make this assumption. See issues #19042 #8446. This commit checks for the presence of the counter_cache key in the options of either the has_many or belongs_to association as well as ensuring that the *_count column is present.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As per the docs, `mark_for_destruction` should do nothing if `autosave` is not set to true. We normally persist associations on a record no matter what if the record is a new record, but we were always skipping records which were `marked_for_destruction?`. Fixes #20882
* | | | 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/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 regression caused by a01d164bRafael Mendonça França2015-07-071-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

However, another expectation should be that setting `type` to `GoodCo` would correctly instantiate the object as a `Company::GoodCo`. That second expectation is what this should fix.
* | / Fix leaky chain on polymorphic associationeileencodes2015-03-153-0/+5
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | Don't redefine autosave association callbacks in nested attrsSean Griffin2015-01-282-0/+2
| | | | | | | | | | | | | | | | These callbacks will already have been defined when the association was built. The check against `reflection.autosave` happens at call time, not at define time, so simply modifying the reflection is sufficient. Fixes #18704
* | Improve consistency of counter caches updating in memorySean Griffin2015-01-261-1/+1
|/ | | | | | | | | | | | | | | | | When we made sure that the counter gets updated in memory, we only did it on the has many side. The has many side only does the update if the belongs to cannot. The belongs to side was updated to update the counter cache (if it is able). This means that we need to check if the belongs_to is able to update in memory on the has_many side. We also found an inconsistency where the reflection names were used to grab the association which should update the counter cache. Since reflection names are now strings, this means it was using a different instance than the one which would have the inverse instance set. Fixes #18689 [Sean Griffin & anthonynavarre]

The preferred way to halt a callback chain is to explicitly `throw(:abort)`.

* | Remove all cases of manuallly wrapping `Arel::Nodes::Quoted`Sean Griffin2014-12-291-1/+1
| | | | | | | | | | | | | | | | | | | | This is no longer required now that we are injecting a type caster object into the Arel table, with the exception of uniqueness validations. Since it calls `ConnectionAdapter#type_cast`, the value has already been cast for the database. We don't want Arel to attempt to cast it further, so we need to continue wrapping it in a quoted node. This can potentially go away when this validator is refactored to make better use of `where` or the predicate builder.
* | Inform Arel we don't need additional type casting in testsSean Griffin2014-12-261-1/+1
| | | | | | | | | | | | | | Part of the larger refactoring to remove type casting from Arel. We can inform it that we already have the right type by wrapping the value in an `Arel::Nodes::Quoted`. This commit can be reverted when we have removed type casting from Arel in Rail 5.1
