extra_data values not being displayed

[colinmccann]

Hi there, I am trying to use :extra_data to search multiple columns in the model. That is, I want a single 'location' input field to show autocompleted results from either the city and country attributes in a model.

The README explains that extra_data is used to 'Passing an array of attributes/column names to this option will fetch and return the specified data'. It's not clear to me if this functions as a solution for me. However, I see this accepted answer on stack: https://stackoverflow.com/questions/30790421/rails-jquery-autocomplete-search-multiple-attributes.

Am I able to use extra_data in this way?

organizations_controller
autocomplete :organization, :city, full: true, limit: 5, :extra_data => [:country]

organization view
= autocomplete_field_tag 'location', '', autocomplete_organization_city_organizations_path

Or do I need to instead overwrite the autocomplete controller method (autocomplete_organization_city)?
This seems to be a pretty common use case, would be great if it was supported...

Thanks
