Я новичок в django и использую django-taggit 0.10a1 для функциональности тегов в моем django 1.4. .2 приложение. Я также попробовал приложение с тегами django, но, поскольку этот проект не поддерживался, а django-taggit имел много положительных отзывов от разработчиков, я выбрал его.
Мне было интересно, может ли кто-нибудь из вас помочь мне с проблемой, которую я вижу. Следуя документации, я добавил:
tags = TaggableManager()
ко всем моим моделям, которые нуждаются в маркировке. Большинство моделей автоматически добавили раздел «Теги» в администраторе django, как указано в документации, но для некоторых моделей раздел «Теги» не отображается в пользовательском интерфейсе администратора. Я не мог понять, почему. Вот пара моделей, которые у меня есть с строкой тегов, объявленной после всех полей. Если вы видите что-то неправильное в размещении этого утверждения в моей модели, и если вы можете сообщить мне, если вы обнаружите какие-либо проблемы, я был бы очень признателен. Ниже приведены примеры нерабочих моделей с TaggableManager:

Я был бы искренне признателен, если бы кто-нибудь из вас мог взглянуть на него и сообщить мне, если вы видите что-то, что я мог пропустить, или если вам нужна дополнительная информация, чтобы понять мою проблему.
Заранее спасибо.
