Provides validation for when one of a set of fields is required not to be blank, but no one particular field is required on its own.
Add this line to your application's Gemfile:
gem 'one_of_many_validator'
And then execute:
$ bundle
Or install it yourself as:
$ gem install one_of_many_validator
A common use case is validating that a user provides either a mobile number or landline phone number.
You could do this like so:
validates_with OneOfManyValidator, :fields => [:mobile, :landline]
This will pass validation if either :mobile or :landline is provided, and will fail validation if both are blank.
The I18n key used will follow the Rails standard, so in this example the error key will be:
activerecord.errors.models.[model_name].attributes.mobile_and_landline_blank
