| * Fix preloader to never reset associations in case they are already loadedBogdan Gusiev2019-03-073-64/+90
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the issue when association is preloaded with a custom preload scope which disposes the already preloaded target of the association by reseting it. When custom preload scope is used, the preloading is now performed into a separated Hash - #records_by_owner instead of the association. It removes the necessaty the reset the association after the preloading is complete so that reset of the preloaded association never happens. Preloading is still happening to the association when the preload scope is empty.

|\ \ | | | | | | Bugfix: Fix false autosave for has_one :through association
| * | Fix unintended autosave on has_one through associationSergiy Kukunin2019-03-221-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes #35680 The problem occurred, when a `has one through` association contains a foreign key (it belongs to the intermediate association). For example, Comment belongs to Post, Post belongs to Author, and Author `has_one :first_comment, through: :first_post`. In this case, the value of the foreign key is comparing with the original record, and since they are likely different, the association is marked as changed. So it updates every time when the origin record updates.
* | | Add Relation#annotate for SQL commentingMatt Yoho2019-03-2115-19/+118
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch has two main portions: 1. Add SQL comment support to Arel via Arel::Nodes::Comment. 2. Implement a Relation#annotate method on top of that. == Adding SQL comment support Adds a new Arel::Nodes::Comment node that represents an optional SQL comment and teachers the relevant visitors how to handle it. Comment nodes may be added to the basic CRUD statement nodes and set through any of the four (Select|Insert|Update|Delete)Manager objects. For example: manager = Arel::UpdateManager.new manager.table table manager.comment("annotation") manager.to_sql # UPDATE "users" /* annotation */ This new node type will be used by ActiveRecord::Relation to enable query annotation via SQL comments. == Implementing the Relation#annotate method Implements `ActiveRecord::Relation#annotate`, which accepts a comment string that will be appeneded to any queries generated by the relation. Some examples: relation = Post.where(id: 123).annotate("metadata string") relation.first # SELECT "posts".* FROM "posts" WHERE "posts"."id" = 123 # LIMIT 1 /* metadata string */ class Tag < ActiveRecord::Base scope :foo_annotated, -> { annotate("foo") } end Tag.foo_annotated.annotate("bar").first # SELECT "tags".* FROM "tags" LIMIT 1 /* foo */ /* bar */ Also wires up the plumbing so this works with `#update_all` and `#delete_all` as well. This feature is useful for instrumentation and general analysis of queries generated at runtime.

* | | | Bulk Insert: Reuse indexes for unique_byKasper Timm Hansen2019-03-202-61/+55
|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I found `:unique_by` with `:columns` and `:where` inside it tough to grasp. The documentation only mentioned indexes and partial indexes. So why duplicate a model's indexes in an insert_all/upsert_all call when we can just look it up? This has the added benefit of raising if no index is found, such that people can't insert thousands of records without relying on an index of some form.
* / / Make aliases of `database` option in generators workyuuji.yaginuma2019-03-202-2/+2
|/ / | | | | | | | | | | | | | | | | | | | | Thor automatically adds `-` if aliases do not start with `-`. https://github.com/erikhuda/thor/blob/0879c1773d188902d54f95174f33961ac33111f8/lib/thor/parser/options.rb#L53 But Thor follows a convention of one-dash-one-letter options. So, even if `-` is added to `db`, it does not work. https://github.com/erikhuda/thor/blob/0879c1773d188902d54f95174f33961ac33111f8/lib/thor/parser/options.rb#L4 Follow up #34021.

OTOH, GeneratedAssociatedMethods is assigned to a constant under the model namespace. This is inconsistent and looks strange in the list of ancestors. There is no particular reason *not* to assign a constant for this (very important) module under the model namespace, so that's what this commit does. Previous to this change, ancestors for an AR class looked like this: ``` => [User (call 'User.connection' to establish a connection), User::GeneratedAssociationMethods, #<ActiveRecord::AttributeMethods::GeneratedAttributeMethods:0x000055ace0f05b08>, ApplicationRecord(abstract), ApplicationRecord::GeneratedAssociationMethods, #<ActiveRecord::AttributeMethods::GeneratedAttributeMethods:0x000055ace093c460>, ActiveRecord::Base, ... ``` With this change, they look like this: ``` => [User (call 'User.connection' to establish a connection), User::GeneratedAssociationMethods, User::GeneratedAttributeMethods, ApplicationRecord(abstract), ApplicationRecord::GeneratedAssociationMethods, ApplicationRecord::GeneratedAttributeMethods, ActiveRecord::Base, ... ``` The previously named `GeneratedAttributeMethods` module builder class is renamed `GeneratedAttributeMethodsBuilder` to emphasize that this is not a module but a class.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | roflscaling (using frozen string constants instead of literal strings) was added in 2012, before frozen string literals were added in Ruby 2.3. Now that Rails no longer supports Ruby <2.3, and all of these files use frozen string literals, there is no reason to keep the roflscaling. This does not delete or deprecate the related constants. Such a change can be made in a later commit.

We'd see the following error: ``` lib/active_record/database_configurations.rb:72:in `block in find_db_config': undefined method `env_name' for [nil]:Array (NoMethodError) ``` The problem here is that Rails does correctly identify this as not a real configuration but returns `[nil]` along with the others. We need to make sure to flatten the array and remove all the `nil`'s before returning the `configurations` objects. Fixes #35646
