Я хочу добавить multi formSet в свой проект. Я следовал https://github.com/shitalluitel/formset этому коду. Но покажите это сообщение об ошибке в моем терминале: «ImproperlyConfigured: вызов modelformset_factory без явного определения полей или исключений запрещен».

inside views.py изменить эту строку 

journalEntryFormset = modelformset_factory( AccountsJournalVouch­erEntery, form=AccountsPymtVoucherF­orm)

на эту 

journalEntryFormset = modelformset_factory( AccountsJournalVouch­erEntery, form=AccountsPymtVoucherF­orm, fields={'field_1', 'field_2', 'field_....'})
