DependentOptionChecker

dependent_option_checker is a simple gem that provides a Rake task to detect missing dependent options in has_many / has_one associations in ActiveRecord models. It also helps identify missing has_many / has_one associations themselves.

• Detects associations lacking a dependent: ... option.
• Identifies missing has_many / has_one associations.
• Outputs the names of models and the specific missing configurations.
• Allows excluding specific tables from the check via a YAML config file.

Add this line to your application's Gemfile:

gem 'dependent_option_checker'

And then execute:

bundle install

bin/rails g dependent_option_checker:install

This will generate a configuration file at config/dependent_option_checker.yml, which you can edit to specify tables to ignore during checks.

Run the following command:

bin/rails dependent_option_checker:check

If any missing configuration is detected, the task will output the corresponding model names and the details of what is missing.

You can create a dependent_option_checker.yml file in your Rails config directory to exclude specific tables and relations from the check:

ignored_tables:
  - users

ignored_relations:
  Organization:
    - employees # alert: this is table name

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
