In my app i use rails_admin and install rails_admin_import.
Model 'Team' :id, :name, :image_url, and belongs_to Sports.
If i try import CSV id, name, image_url, sport_id 1, Toronto, , 1
Program created new record but sport is Null.
I was using rails_admin_import 1.3.0 and specified "Related fields mapping" to appropriate column in the other table. It worked for me.
