Composite primary keys improvements and more

Hi, it’s Wojtek with this week’s changes in the Rails codebase.

Allow specifying WHERE clauses with column-tuple syntax.
Querying through Active Record where now accepts a tuple syntax which accepts, as a key, an array of columns and, as a value, an array of corresponding tuples. This improves support for composite primary keys.

Accept composite primary key in id=
This feature modifies the Active Record id accessor to accept an array in composite primary key contexts.

Extract sample rate in the Audio Analyzer
Add sample_rate to ActiveStorage::Analyzer::AudioAnalyzer output.

Run a load hook when TestFixtures is included
Introduces active_record_fixtures lazy load hook. Hooks defined with this name will be run whenever TestFixtures is included in a class.

ActiveSupport.on_load(:active_record_fixtures) do
  self.fixture_paths << "test/fixtures"

Allow SQL Warnings to be ignored using error codes

Active Record configuration allows now to ignore the warning codes like this:

config.active_record.db_warnings_ignore = [
  "1062" # MySQL Error 1062: Duplicate entry
