You have more than one solution, i think of 2:
1. has_many is very configurable, check the api. You can make special
queries, filters, etc. This approach seems the best if your complex
logic is just on the find method.
2. put the special logic on a controller:
class FilteredTranslations < ActionController
active_scaffold :translations do |config|
...some config...
end
def conditions_for_collection
...some logic...
end
# use a before_filter to use session or user parameters.
# put before_filter :before_filter_config inside controller class
def before_filter_config
active_scaffold_config.label = "translations made by #
{current_user.name}"
end
# and last: add the nested link onto the other controller, and
intercepting the relation.
def self.active_scaffold_controller_for(klass)
return FilteredTranslationsController if klass == Translation
return "#{klass}ScaffoldController".constantize rescue super
end
