If you are upgrading to ransack from meta_search, and you are missing
being able to use
attr_unsearchable to hide various model methods from
search, you can add this to your model instead:
def self.ransackable_attributes(auth_object = nil) (column_names - ['company_name']) + _ransackers.keys end
In this case,
company_name will no longer be searchable with the
dynamic scopes that ransack creates.
