Instance Method Details

#translate_association(key, assoc = nil, **variables) ⇒ Object Also known as: ta

Translates the passed key for an active record association. This helper is used for rendering association dependent keys in forms like :no_entry, :none_available or :please_select. The key is looked up in the following order:

- activerecord.associations.models.{model_name}.{association_name}.{key}
- activerecord.associations.{association_model_name}.{key}
- global.associations.{key}

def translate_association(key, assoc = nil, **variables)
  if assoc && assoc.options[:polymorphic].nil?
    variables[:default] ||= [association_klass_key(assoc, key).to_sym,
                             :"global.associations.#{key}"]
    t(association_owner_key(assoc, key), **variables)
  else
    t("global.associations.#{key}", **variables)
  end
end

#translate_inheritable(key, **variables) ⇒ Object Also known as: ti

Translates the passed key by looking it up over the controller hierarchy. The key is searched in the following order:

- {controller}.{current_partial}.{key}
- {controller}.{current_action}.{key}
- {controller}.global.{key}
- {parent_controller}.{current_partial}.{key}
- {parent_controller}.{current_action}.{key}
- {parent_controller}.global.{key}
- ...
- global.{key}
