Пожалуйста, помогите .... я пытаюсь использовать solr, pysolr и haystack в моем поиске по сайту django. Я отредактировал скрипт haystack build_solr_schema для использования BaseCommand.add_argument (), удалив список параметров по умолчанию. Ниже приведены мои версии;
Python 3.5.2
Джанго 1.11.11
Solr-7.3.0
Джанго-Хейстек 2.4.0
pysolr 3.7.0

Пожалуйста, помогите, если есть какой-либо другой способ решения этой проблемы, без необходимости редактировать build_solr_schema стога сена или любое другое решение этой проблемы .. Спасибо
