| * | | Fix .new with multiple through associationsSam DeCesare2018-04-091-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a bug with building an object that has multiple `has_many :through` associations through the same object. Previously, when building the object via .new, the intermediate object would be created instead of just being built. Here's an example: Given a GameBoard, that has_one Owner and Collection through Game. The following line would cause a game object to be created in the database. GameBoard.new(owner: some_owner, collection: some_collection) Whereas, if passing only one of those associations into `.new` would cause the Game object to be built and not created in the database. Now the above code will only build the Game object, and not save it.

However, supporting identity data type will make `prefetch_primary_key?` returns `false` then no primary key column name added. As a result, `empty_insert_statement_value` raises `NotImplementedError` To address this error `empty_insert_statement_value` can take one argument `primary_key` to generate insert statement like this. `INSERT INTO "POSTS" ("ID") VALUES(DEFAULT)` It needs arity change for the public method but no actual behavior changes for the bundled adapters.

Example: ``` shared: adapter: mysql2 host: <%= ENV["DB_HOST"] || "localhost" %> username: root connect_timeout: 0 pool: 100 reconnect: true development: database: development_db adapter: mysql2 ``` To fix, only create a DatabaseConfig object when an adapter, database, or URL are present. The merging behavior for `shared` doesn't work with a 3-tier config. I don't think it worked before this change either - since Rails doesn't know which point to merge it in. That's something we may have to fix with the refactoring I'm working on.

* | Avoid generating full changes hash on every saveEugene Kenny2018-04-081-1/+1
| | | | | | | | | | | | | | | | | | | | `changed_attribute_names_to_save` is called in `keys_for_partial_write`, which is called on every save when partial writes are enabled. We can avoid generating the full changes hash by asking the mutation tracker for just the names of the changed attributes. At minimum this saves one array allocation per attribute, but will also avoid calling `Attribute#original_value` which is expensive for serialized attributes.

In addition. Before 5.2, if both an AR model class and a Relation instance have same named methods (e.g. `arel_attribute`, `predicate_builder`, etc), named scope doesn't respect relation instance information. For example: ```ruby class Post < ActiveRecord::Base has_many :comments1, class_name: "RecentComment1" has_many :comments2, class_name: "RecentComment2" end class RecentComment1 < ActiveRecord::Base self.table_name = "comments" default_scope { where(arel_attribute(:created_at).gteq(2.weeks.ago)) } end class RecentComment2 < ActiveRecord::Base self.table_name = "comments" default_scope { recent_updated } scope :recent_updated, -> { where(arel_attribute(:updated_at).gteq(2.weeks.ago)) } end ``` If eager loading `Post.eager_load(:comments1, :comments2).to_a`, `:comments1` (default_scope) respects aliased table name, but `:comments2` (using named scope) may not work correctly since named scope doesn't respect relation instance information. See also 801ccab. But this is a breaking change between releases without deprecation. I decided to bring back private class methods accessibility in named scope. Fixes #31740. Fixes #32331.

|/ / / | | | | | | | | | | | | | | | | | | | | | | | | An entry in `ActiveRecord::Base.configurations` can either be a connection spec ("two-level") or a hash of specs ("three-level"). We were detecting two-level configurations by looking for the `database` key, but the database can also be specified as part of the `url` key, which meant we incorrectly treated those configurations as three-level.

This is the correct behaviour when a new record is assigned, but not when the existing record is preloaded. As long as we mark the association as loaded, we can skip setting the target when the record is missing and avoid clobbering the foreign key.

Currently this is determined by checking if the foreign key name is `fk_rails_` followed by a 10-character hash. At [Cookpad](https://github.com/cookpad), we use [Departure](https://github.com/departurerb/departure) (Percona's pt-online-schema-change runner for ActiveRecord migrations) to run migrations. Often, `pt-osc` will make a copy of a table in order to run a long migration without blocking it. In this copy process, foreign keys are copied too, but [their name is prefixed with an underscore to prevent name collision ](https://www.percona.com/doc/percona-toolkit/LATEST/pt-online-schema-change.html#cmdoption-pt-online-schema-change-alter-foreign-keys-method). In the process described above, we often end up with a development database that contains foreign keys which name starts with `_fk_rails_`. That name does not match the ignore pattern, so next time Rails dumps the database schema (eg. when running `rake db:migrate`), our `db/schema.rb` file ends up containing those unwanted foreign key names. This also produces an unwanted git diff that we'd prefer not to commit. In this PR, I'd like to suggest a way to expose the foreign key name ignore pattern to the Rails configuration, so that individual projects can decide on a different pattern of foreign keys that will not get their names dumped in `schema.rb`.

I was considering doing this in a future refactoring but our set up forced me to move it now. You see there are `mattr_accessor`'s on the Core module that have default settings. For example the `schema_format` defaults to Ruby. So if I call `configs_for` or any methods in the Core module it will reset the `schema_format` to `:ruby`. By moving it to it's own class we can keep the logic contained and avoid this unfortunate issue. The second change here does a double loop over the yaml files. Bear with me... Our tests dictate that we need to load an environment before our rake tasks because we could have something in an environment that the database.yml depends on. There are side-effects to this and I think there's a deeper bug that needs to be fixed but that's for another issue. The gist of the problem is when I was creating the dynamic rake tasks if the yaml that that rake task is calling evaluates code (like erb) that calls the environment configs the code will blow up because the environment is not loaded yet. To avoid this issue we added a new method that simply loads the yaml and does not evaluate the erb or anything in it. We then use that yaml to create the task name. Inside the task name we can then call `load_config` and load the real config to actually call the code internal to the task. I admit, this is gross, but refactoring can't all be pretty all the time and I'm working hard with `@tenderlove` to refactor much more of this code to get to a better place re connection management and rake tasks.

The change here allows for the database commands to operate on all the configs in the environment. Previously we couldn't slice the hashes and iterate over them becasue they could be two tier or could be three tier. By using the database config structs we don't need to care whether we're dealing with a three tier or two tier, we can just parse all the configs based on the environment. This makes it possible for us to run `bin/rails db:create` and it will create all the configs for the dev and test environment ust like it does for a two tier - it creates the db for dev and test. Now `db:create` will create `primary` for dev and test, and `animals` for dev and test if our database.yml looks like: ``` development: primary: etc animals: etc test: primary: etc animals: etc ``` This means that `bin/rails db:create`, `bin/rails db:drop`, and `bin/rails db:migrate` will operate on the dev and test env for both primary and animals ds.
