最近インストールdjango-parler==2.2
したのですが、モデルを書き直して継承TranslatableModel
しようとするmakemigrations
と、次のエラーが発生します。
main_menu_slug = models.SlugField(max_length=120, unique=main_menu_item)
NameError: name 'main_menu_item' is not defined
から継承すると、すべて正常に動作しmodels.Model
ます。コードは次のとおりです。
class MenuItem(TranslatableModel):
translations = TranslatedFields (
main_menu_item = models.CharField(max_length=60),
main_menu_slug = models.SlugField(max_length=120, unique=main_menu_item)
)
このモジュールを使い始めたばかりなので、些細なことかもしれませんが、解決策が見つかりませんでした。私が間違っていることは何ですか?

作業コードmodels.Model
:
class MenuItem(models.Model):
main_menu_item = models.CharField(max_length=60)
main_menu_slug = models.SlugField(max_length=120, unique=main_menu_item)
