In virtual field functions, you must refer to the table name and field name
within each row object, so:
return gi.country_code_by_addr(row.melodigram_play.from_where)
should be:
return gi.country_code_by_addr(row.from_where)
That doesn't explain the problem below, but I wonder if something else is
going on there (e.g., is the app compiled, and you didn't re-compile after
making the change?).
As an aside, if you already have a function, no need to wrap it in a lambda
-- just do:
Field.Virtual('from_country', get_country)
