Choose the right location and scope for your Rails configuration options to improve maintainability and clarity:

1. Use appropriate namespaces - For truly global configurations, place them on the module rather than on a specific class: ```ruby

   Preferred for global settings

   ActiveRecord.configuration_option = value

Avoid for global settings

ActiveRecord::Base.configuration_option = value

2. **Use environment-specific files** for environment-specific configurations:
```ruby
# config/environments/development.rb
config.active_record.verbose_query_logs = true

1. Use load hooks for adapter-specific configurations:

   # config/application.rb or an initializer
   ActiveSupport.on_load(:active_record_postgresqladapter) do
     self.datetime_type = :timestamptz
   end
   

2. Prefer simplified syntax when available: ```ruby

   Instead of

   config.yjit = true config.yjit_options = { stats: true }

Prefer

config.yjit = { stats: true } ```

Using appropriate configuration placement improves organization, reduces conflicts between environments, and makes your application more maintainable.
