Trying to use custom fields with the inline plugin but I get a NameError

[vazaha-nl]

I am trying to use custom fields provided by another plugin with the inline plugin, but it does not seem to work. The standard fields are available in python but custom fields provided by other plugins give a python NameError.

Context: I use the beets-artistcountry plugin to get the country of the artist. It is available in the $artist_country variable and I can use it in my paths definition, like this, and it works:

paths:
  albumtype:album: Modern/$artist_country/$albumartist/$album%aunique{}/$albumartist - $album - $track. $title

But I want to get one step deeper and retrieve the country name, and the continent for that artist_coutry. I am able to do that using the inline plugin and a python snippet. I got it working for the default country field but that is the country of release, not the artist country. So I want to do the same with artist_country.

However, artist_country seems not to be accessible in python using the inline plugin. I get a NameError: name 'artist_country' is not defined error.

Relevant parts from my config:

plugins:
  - artistcountry
  - inline

item_fields:
  country_name: |
    import pycountry_convert
    country_name = pycountry_convert.country_alpha2_to_country_name(artist_country)
    return country_name

  continent_name: |
    import pycountry_convert
    continent_code = pycountry_convert.country_alpha2_to_continent_code(artist_country)
    continent_name = pycountry_convert.convert_continent_code_to_continent_name(continent_code)
    return continent_name

paths:
  albumtype:album: Modern/$continent_name/$country_name/$albumartist/$album%aunique{}/$albumartist - $album - $track. $title

Error output when I do an import is:

beetsplug.inline.InlineError: error in inline path field code:
import pycountry_convert
continent_code = pycountry_convert.country_alpha2_to_continent_code(artist_country)
continent_name = pycountry_convert.convert_continent_code_to_continent_name(continent_code)
return continent_name

NameError: name 'artist_country' is not defined

Try:

  country_name: |
    import pycountry_convert
    artist_country = item['artist_country']
    country_name = pycountry_convert.country_alpha2_to_country_name(artist_country)
    return country_name

Thanks for your answer, unfortunately this also doesn't work. I get NameError: name 'item' is not defined

I added some debug code to print all the available globals with

  country_name: |
    from pprint import pprint
    pprint(globals())

but artist_country is not available anywhere. There is a items var but the items also do not contain a artist_country property.

Also looking at the documentation it looks like the custom fields are only available in path definitions and not in other plugins? Then what I want is indeed not possible using the inline plugin, which is unfortunate.

Maybe I will try to write my own plugin that adds %country_name{country_code} and %continent_name{country_code} path functions, that should accomplish what I want.
