* Resolve association class correctly when assigning ids on a through associationMatthew Draper2016-12-091-0/+4

| | | | | | | | Fixes casting of IDs to the data type of the association primary key, rather than then the data type of the model's primary key. (Tests use a string primary key on the association, rather than an int.) Tests issue #20995

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the changes in #25337, double save bugs are pretty much impossible, so we can just lift this restriction with pretty much no change. There were a handful of cases where we were relying on specific quirks in tests that had to be updated. The change to has_one associations was due to a particularly interesting test where an autosaved has_one association was replaced with a new child, where the child failed to save but the test wanted to check that the parent id persisted to `nil`. I think this is almost certainly the wrong behavior, and I may change that behavior later. But ultimately the root cause was because we never remove the parent in memory when nullifying the child. This makes #23197 no longer needed, but it is what we'll do to fix some issues on 5.0 Close #23197

| | | | | | | | | | | | | | | | `ThroughReflection` initializes `@delegate_reflection` and delegate all public methods to `delegate_reflection`. But `PolymorphicReflection` does not initialize `@delegate_reflection`. It is enough to inherit `AbstractReflection` (using `alias_candidate` only).

This is to keep sentences within Rails itself consistent and with a '.' at the end.
* start hiding the `scope_chain` data structureAaron Patterson2016-03-041-0/+10
| | | | | Introduce a predicate method that doesn't need to build a scope chain, but also hides the data structure used for representing the scope chain.
* don't build the reflection chain to calculate `nested?`Aaron Patterson2016-03-041-1/+9
| | | | | | | | We know a reflection can be considered as `nested?` if the source reflection or the through reflection are also through reflections (since the through reflection will also add another join table). This allows us to avoid traversing the entire reflection tree just to calculate whether or not there will be more join tables.

* Respect through association scopes when used with polymorphicSean Griffin2016-02-291-1/+1
| | | | | | | | | | | When the `source_type` option is passed to a has_many through, the resulting `Reflection` will be an instance of `PolymorphicReflection` and not `ThroughReflection`, meaning that it will ignore the scopes that it needs to apply from the through reflections. This adds an additional delegation call to remedy this. I've been finding the reflection code completely impenetrable lately, it could use some major love. Fixes #22726
* build scope chain functionally and remove cachingAaron Patterson2016-02-101-14/+40
| | | | | | | This commit walks the reflection tree and builds the scope chain functionally. It also removes the chain cache since the cache doesn't seem to have any impact on performance (I'd prefer to only cache at proven bottlenecks)

* | Remove `case macro` from `calculate_constructable`yui-knk2016-02-011-8/+13
| | | | | | | | | | | | | | | | | | Rails has abstract Reflection classes (`MacroReflection`, `AssociationReflection` etc.) and concrete Reflection classes (e.g. `HasManyReflection`, `HasOneReflection` etc.). In many case `calculate_constructable` returns `true`, so change `calculate_constructable` to always return `true` and override this method if necessary.

* Freeze association foreign keys to reduce allocationsSean Griffin2015-11-151-1/+1
| | | | | | | | | | | | The string returned here will ultimately get used as a key of a hash in the attribute set once the attributes are being built. When you give a non-frozen string to `Hash#[]`, it will be duped. Be freezing we can significantly reduce the number of times we end up allocating `"user_id"` This does not include any additional tests, as this should not have any public facing implications. If you are mutating the result of `Reflection#foreign_key`, please stop.

* Fix regression in inverse_of on through associationseileencodes2015-09-261-14/+16
| | | | | | | | | | | | | | | | | | | `inverse_of` on through associations was accidently removed/caused to stop working in commit f8d2899 which was part of a refactoring on `ThroughReflection`. To fix we moved `inverse_of` and `check_validity_of_inverse!` to the `AbstractReflection` so it's available to the `ThroughReflection` without having to dup any methods. We then need to delegate `inverse_name` method in `ThroughReflection`. `inverse_name` can't be moved to `AbstractReflection` without moving methods that set the instance variable `@automatic_inverse_of`. This adds a test that ensures that `inverse_of` on a `ThroughReflection` returns the correct class name, and the correct record for the inverse relationship. Fixes #21692

| * HasManyAssociation: moved half of counter cache code to reflectionBogdan Gusiev2015-09-031-9/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current implementation has a lot of utility methods that accept reflection call a lot of methods on it and exit. E.g. has_counter_cache?(reflection) It causes confusion and inability to cache result of the method even through it always returns the same result for the same reflection object. It can be done easier without access to the association context by moving code into reflection itself. e.g. reflection.has_counter_cache? Reflection is less complex object than association so moving code there automatically makes it simplier to understand.

* Rename association option :class to :anonymous_classAndrew White2015-04-211-2/+2
| | | | | | | | | | | | | In 1f006c an option was added called :class to allow passing anonymous classes to association definitions. Since using :class instead of :class_name is a fairly common typo even amongst experienced developers this can result in hard to debug errors arising in raise_on_type_mismatch? To fix this we're renaming the option from :class to :anonymous_class as that is a more correct description of what the option is for. Since this was an internal, undocumented option there is no need for a deprecation. Fixes #19659
* Add `clear_association_scope_cache` methodeileencodes2015-03-181-0/+15
| | | | | | | | | | | | | In the tests if I were to call `post.categorizations.to_a` and then later call `post.categorizations.to_a` expecting to have different results the 2 queries would be the same because of the caching involved in `@association_scope_cache`. The chain gets cached and the queries will be the same even if they are not supposed to be (i.e. testing an order dependent scoping issue). I found this issue because I was working on a bug with cached scoped in hm:t and hm:t polymorphic relationships but `capture_sql` was outputting the wrong SQL to write a good test.

* Fix leaky chain on polymorphic associationeileencodes2015-03-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
