Features

Or install it yourself as:

gem install safe_params

Usage

In the Model

class User < ApplicationRecord
  include SafeParams
  safe_params :name, :email, nested: { address_attributes: [:city, :zip] }
end

In the Controller

def user_params
  safe_params(User)
end

YAML Config (Optional)

  - name
  - email
  - address_attributes:
      - city
      - zip

CLI Generator

bundle exec ruby -Ilib -r safe_params/cli -e "SafeParams::CLI.start(['generate', 'User'])"
