# you see 2 models and 1 apstract parent class.
# I need to import into django project 189 Country objects (only by name, I do not have IDs)

# And then 5000 cities, only by names, I don't have IDs. And I do not want to use IDs of Country objects during import. I need to use also their names
# So example of my .csv file would be
# name      country
# Rome      Italy
# Moscow    Russia
# ...
# ...
# ...

# What should be my approach to solve that task?
