| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The documentation previously claimed that `db/schema.rb` was "the authoritative source for your database schema" while simultaneously also acknowledging that the file is generated. These two statements are incongruous and the guides accurately call out that many database constructs are unsupported by `schema.rb`. This change updates the comment at the top of `schema.rb` to remove the assertion that the file is authoritative. The documentation also previously referred vaguely to "issues" when re-running old migrations. This has been updated slightly to hint at the types of problems that one can encounter with old migrations. In sum, this change attempts to more accurately capture the pros, cons, and shortcomings of the two schema formats in the guides and in the comment at the top of `schema.rb`.

| * | | Fix .new with multiple through associationsSam DeCesare2018-04-097-1/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

When `Rails.root` is defined, `config[:database]` will look something like `vagrant/rails/activerecord/db/primary.sqlite3` instead of just `db/primary.sqlite3`. (See https://github.com/rails/rails/blob/00caf95e14b90782ab17fbd6d2b930844df99980/activerecord/lib/active_record/connection_adapters/sqlite3_adapter.rb#L27) Relaxing `assert_equal` to `assert_match` will allow these tests to pass regardless of how they are run. I do have a question why we need both ways to run tests. I have been using `bin/test` lately, but I see from #32426 that this is not the preferred method.

DEFAULT VALUES` then every insert statement needs at least one column name specified. When `prefetch_primary_key?` returns `true` insert statement always have the primary key name since the primary key value is selected from the associated sequence. 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.

| * | Prevent changes_to_save from mutating attributesEugene Kenny2018-04-081-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an array of hashes is added to a `HashWithIndifferentAccess`, the hashes are replaced with HWIAs by mutating the array in place. If an attribute's value is an array of hashes, `changes_to_save` will convert it to an array of HWIAs as a side-effect of adding it to the changes hash. Using `merge!` instead of `[]=` fixes the problem, as `merge!` copies any array values in the provided hash instead of mutating them.

|/ / | | | | | | | | | | | | | | | | | | `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.
