* Fix the test that was broken by #16445 rather than deleting itSean Griffin2015-07-191-0/+12
| | | | | | | | Since the counter cache was properly being updated, the model became stale. Simply reloading the model before attempting to destroy is sufficient for this case. I believe this is enough of an edge case to be a valid change to the tests, even though it represents a potential breaking change.
* Fix counter_cache for polymorphic associationsStefan Kanev2015-07-196-16/+34
| | | | | | | | | | | | | | 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`.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* / Ensure that `ActionController::Parameters` can still be passed to ARSean Griffin2015-07-183-0/+33
|/ | | | | | | | | | | | | | | | | | | | | Since nested hashes are also instances of `ActionController::Parameters`, and we're explicitly looking to work with a hash for nested attributes, this caused breakage in several points. This is the minimum viable fix for the issue (and one that I'm not terribly fond of). I can't think of a better place to handle this at the moment. I'd prefer to use some sort of solution that doesn't special case AC::Parameters, but we can't use something like `to_h` or `to_a` since `Enumerable` adds both. While I've added a trivial test case for verifying this fix in isolation, we really need better integration coverage to prevent regressions like this in the future. We don't actually have a lot of great places for integration coverage at the moment, so I'm deferring it for now. Fixes #20922.
* Silence deprecation warning from force reloadPrem Sichanugrist2015-07-1610-105/+125
| | | | | | | | | | | | We deprecate the support for passing an argument to force reload in 6eae366d0d2e5d5211eeaf955f56bd1dc6836758. That led to several deprecation warning when running Active Record test suite. This commit silence the warnings by properly calling `#reload` on the association proxy or on the association object instead. However, there are several places that `ActiveSupport::Deprecation.silence` are used as those tests actually tests the force reload functionality and will be removed once `master` is targeted next minor release (5.1).
* Deprecate force association reload by passing truePrem Sichanugrist2015-07-159-0/+70
| | | | | | | | | | | | | | | | | | This is to simplify the association API, as you can call `reload` on the association proxy or the parent object to get the same result. For collection association, you can call `#reload` on association proxy to force a reload: @user.posts.reload # Instead of @user.posts(true) For singular association, you can call `#reload` on the parent object to clear its association cache then call the association method: @user.reload.profile # Instead of @user.profile(true) Passing a truthy argument to force association to reload will be removed in Rails 5.1.

* | Replaced `ActiveSupport::Concurrency::Latch` with concurrent-ruby.Jerry D'Antonio2015-07-133-21/+26
|/ | | | | | | | | | The concurrent-ruby gem is a toolset containing many concurrency utilities. Many of these utilities include runtime-specific optimizations when possible. Rather than clutter the Rails codebase with concurrency utilities separate from the core task, such tools can be superseded by similar tools in the more specialized gem. This commit replaces `ActiveSupport::Concurrency::Latch` with `Concurrent::CountDownLatch`, which is functionally equivalent.
* Fix regression caused by a01d164bRafael Mendonça França2015-07-073-2/+37
| | | | | | | | | 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.

| | | | | | | | | | | After 908cfef was introduced fixtures that did not set an enum would return nil instead of the default enum value. The fixtures should assume the default if a different enum is not defined. The change checks first if the enum is defined in the fixture before setting it based on the fixture.
* Correct through associations using scopesSean Griffin2015-06-304-6/+16
| | | | | | | | | | | | | | | | | | | | | | The changes introduced to through associations in c80487eb were quite interesting. Changing `relation.merge!(scope)` to `relation = relation.merge(scope)` should in theory never cause any changes in behavior. The subtle breakage led to a surprising conclusion. The old code wasn't doing anything! Since `merge!` calls `instance_exec` when given a proc, and most scopes will look something like `has_many :foos, -> { where(foo: :bar) }`, if we're not capturing the return value, it's a no-op. However, removing the `merge` causes `unscope` to break. While we're merging in the rest of the chain elsewhere, we were never merging in `unscope` values, causing a breakage on associations where a default scope was being unscoped in an association scope (yuk!). This is subtly related to #20722, since it appears we were previously relying on this mutability. Fixes #20721. Fixes #20727.

* Revert the behavior of association names and `where` to be closer to 4.2Sean Griffin2015-06-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this change, we will always assume the association name is the same as the table it's referencing. This is subtly different than treating the hash key passed to `where` as the table name, as it still allows the class referenced by the association to provide additional type information. After exploring several possible solutions to the ambiguity problem, I do not think there is a short term answer that will maintain backwards compatibility. This change will make it so the following code does not work: class User has_many :approved_posts, -> { where(approved: true) }, class_name: "Post" end User.where(approved_posts: { id: 1 }) But prevents potential ambiguity and collision as demonstrated in [this gist](https://gist.github.com/senny/1ae4d8ea7b0e269ed7a0). Unfortunately, truely solving this requires significantly re-architecting this code, so that what is currently represented as an `Arel::Attribute` is instead another data structure that also references the association it is representing, so we can identify the proper table name for aliasing when we construct the final tree. While I'd still like to accomplish that in the long run, I don't think I'll be able to get there in time for Rails 5 (since I'm not full time OSS any more, and this is several weeks worth of work). I'm hoping to achieve this for Rails 5.1. Fixes #20308

| * More granular console SQL colorationChris Tonkinson2015-06-231-8/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This new coloration approach makes it easier to scan the rails console for specific types of activity with more fine-grained visual cues. Virtual terminal ANSI color escape codes are used when displaying SQL statements in the rails console. The former implementation alternates line prefix information (including the statement name and execution latency) between CYAN and MAGENTA. This visually differentiates any SQL statements in the log and is useful for quickly scanning for database activity. While a great idea and a solid foundation, alternating between just two colors on an even/odd basis (much like striping an HTML table) can be improved upon. This patch replaces the even/odd striping with a more comprehensive scheme that applies coloration based on the type of statement being run. Every statement logged has its prefix (name and latency) colored white (as the statement body was previously). The statement body is now colored according to the nature of the statement: - INSERT statements are GREEN (symbolic of creation or genesis) - SELECT statements are BLUE (typically used for informational displays, as SELECT statements do not normally have side-effects) - DELETE statements are RED (commonly used to indicate the danger of a destructive action) - UPDATE statements are YELLOW (it's like a less extreme RED :P) - TRANSACTION statements are CYAN (arbitrary) - and any other statements are MAGENTA (again, arbitrary)

|/ / | | | | | | | | | | | | | | | | | | | | After discussing, we've decided it makes more sense to include it. We're already forwarding every conflicting method to `to_a`, and there's no conflation of concerns. `Enumerable` has no mutating methods, and it just allows us to simplify the code. No existing methods will have a change in behavior. Un-overridden Enumerable methods will simply delegate to `each`. [Sean Griffin & bogdan]
