* pg, `create_schema`, `drop_schema` and `rename_table` quote schema name.Yves Senn2015-08-281-0/+12
| | | | | | | | Closes #21418. Previously schema names were not quoted. This leads to issues when a schema names contains a ".". Methods in `schema_statements.rb` should quote user input.

* Only nullify persisted has_one target associationsAgis-2015-08-241-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | 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.
* uniqueness validation raises error for persisted record without pk.Yves Senn2015-08-201-0/+7
| | | | | | | | Closes #21304. While we can validate uniqueness for record without primary key on creation, there is no way to exclude the current record when updating. (The update itself will need a primary key to work correctly).

* | Add ActiveRecord::Relation#in_batchesSina Siadat2015-08-071-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `in_batches` yields Relation objects if a block is given, otherwise it returns an instance of `BatchEnumerator`. The existing `find_each` and `find_in_batches` methods work with batches of records. The new API allows working with relation batches as well. Examples: Person.in_batches.each_record(&:party_all_night!) Person.in_batches.update_all(awesome: true) Person.in_batches.delete_all Person.in_batches.map do |relation| relation.delete_all sleep 10 # Throttles the delete queries end

* | | `destroy` shouldn't raise when child associations fail to saveSean Griffin2015-07-241-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Deep down in the association internals, we're calling `destroy!` rather than `destroy` when handling things like `dependent` or autosave association callbacks. Unfortunately, due to the structure of the code (e.g. it uses callbacks for everything), it's nearly impossible to pass whether to call `destroy` or `destroy!` down to where we actually need it. As such, we have to do some legwork to handle this. Since the callbacks are what actually raise the exception, we need to rescue it in `ActiveRecord::Callbacks`, rather than `ActiveRecord::Persistence` where it matters. (As an aside, if this code wasn't so callback heavy, it would handling this would likely be as simple as changing `destroy` to call `destroy!` instead of the other way around). Since we don't want to lose the exception when `destroy!` is called (in particular, we don't want the value of the `record` field to change to the parent class), we have to do some additional legwork to hold onto it where we can use it. Again, all of this is ugly and there is definitely a better way to do this. However, barring a much more significant re-architecting for what I consider to be a reletively minor improvement, I'm willing to take this small hit to the flow of this code (begrudgingly).
* | | Rename the enum_{prefix,suffix} options to _{prefix,suffix}Robin Dupret2015-07-231-1/+1
| | | | | | | | | | | | | | | | | | This makes it more clear that they are reserved keywords and also it seems less redundant as the line already starts with the call to the `enum` method.
* | | Extra caller details added to ActiveRecord::RecordNotFoundSameer Rahmani2015-07-211-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ActiveRecord::RecordNotFound modified to store model name, primary_key and id of the caller model. It allows the catcher of this exception to make a better decision to what to do with it. For example consider this simple example: class SomeAbstractController < ActionController::Base rescue_from ActiveRecord::RecordNotFound, with: :redirect_to_404 private def redirect_to_404(e) return redirect_to(posts_url) if e.model == 'Post' raise end end
* | | Deprecate and rename the keys for association restrict_dependent_destroyRoque Pinel2015-07-201-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously `has_one` and `has_many` associations were using the `one` and `many` keys respectively. Both of these keys have special meaning in I18n (they are considered to be pluralizations) so by renaming them to `has_one` and `has_many` we make the messages more explicit and most importantly they don't clash with linguistical systems that need to validate translation keys (and their pluralizations). The `:'restrict_dependent_destroy.one'` key should be replaced with `:'restrict_dependent_destroy.has_one'`, and `:'restrict_dependent_destroy.many'` with `:'restrict_dependent_destroy.has_many'`. [Roque Pinel & Christopher Dell]
* | | Fix state being carried over from previous transactionRoque Pinel2015-07-201-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This clears the transaction record state when the transaction finishes with a `:committed` status. Considering the following example where `name` is a required attribute. Before we had `new_record?` returning `true` for a persisted record: ```ruby author = Author.create! name: 'foo' author.name = nil author.save # => false author.new_record? # => true ```
* | | Correctly ignore `mark_for_destruction` without `autosave`Sean Griffin2015-07-201-0/+7
|/ / | | | | | | | | | | | | | | | | 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/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Griffin2015-07-181-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* | Deprecate force association reload by passing truePrem Sichanugrist2015-07-151-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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'Antonio2015-07-131-0/+5
| | | | | | | | | | | | | | | | | | | | 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.

* | Correct through associations using scopesSean Griffin2015-06-301-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* | `dump_schema_after_migration` applies migration tasks other than db:migrateYves Senn2015-06-301-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | Closes #20743. The task `db:_dump` now only dumps the schema if `ActiveRecord::Base.dump_schema_after_migration` is true. This has effects: - `db:migrate:up` - `db:migrate:down` - `db:forward` - `db:rollback`
* | Add reversible syntax for change_column_defaultPrem Sichanugrist2015-06-261-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | Passing `:from` and `:to` to `change_column_default` makes this command reversible as user has defined its previous state. So, instead of having the migration command as: change_column_default(:posts, :state, "draft") They can write it as: change_column_default(:posts, :state, from: nil, to: "draft")

* | | Include `Enumerable` in `ActiveRecord::Relation`Sean Griffin2015-06-191-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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]
* | | Use `Enumerable#sum` on `ActiveRecord::Relation` when a block is givenSean Griffin2015-06-191-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | This matches our behavior in other cases where useful enumerable methods might have a different definition in `Relation`. Wanting to actually enumerate over the records in this case is completely reasonable, and wanting `.sum` is reasonable for the same reason it is on `Enumerable` in the first place.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a getter has side effects on the DB, `changes_applied` will be called twice. The second time will try and remove the changed attributes cache, and will crash because it's already been unset. This also demonstrates that we shouldn't assume that calling getters won't change the value of `changed_attributes`, and we need to clear the cache if an attribute is modified. Fixes #20531.
