Overview

Options

Manages database connection options from multiple configuration sources. This class is responsible for:

  • Loading configuration from various sources (YAML files, environment variables, .env files)
  • Applying precedence rules for configuration sources
  • Processing adapter-specific options (especially PostgreSQL schema handling)
  • Managing Sequel extensions
  • Setting up after_connect callbacks

Configuration Sources (in order of precedence)

  1. Passed options (highest priority)
  2. .env file
  3. Environment variables
  4. config/database.yml
  5. ~/.config/sequelizer/database.yml (lowest priority)

Examples:

Basic usage

options = Options.new(adapter: 'postgres', host: 'localhost')
hash = options.to_hash

Loading from environment

ENV['SEQUELIZER_ADAPTER'] = 'postgres'
options = Options.new
puts options.adapter  # => 'postgres'
