KeyError: ('profiles', 'talk') - Как мне решить?

Question

новичок здесь. Пытается создать приложение, используя Django и Postgres db. Я изо всех сил мигрировать в данный момент получаю эту ошибку «KeyError: („Профили“,„говорить“)»

Вот моя ошибка из моей командной строки после попытки переноса:

Не уверен, что, если я дал слишком много или слишком мало информации, но, будучи новичком, я понятия не имею, что значит ошибка или какая информация вам может понадобиться, чтобы понять это!

Заранее благодарю вас за помощь в решении этой проблемы и ваше терпение, глядя на весь мой ужасный код! : -s

Answer 1

Это происходит, когда вы выполните следующие действия:

1. Run

migrate appname

и исполнение остановлено из-за ошибки.

2. Вы запускаете его снова, но на этот раз его ошибка, потому что новая таблица уже создана.

3. Вы редактируете файл миграции, удалите код, создающий таблицу , а затем выполните миграцию снова.

Мой обходной путь, вместо удаления CreateModel, я переехал ее к предыдущей миграции файла.

Answer 2

Вам лучше показать код ваших файлов миграции в этой проблеме, потому что проблема, вероятно, есть.

Возможно, у вас не было файла миграции, в котором вы создали свою модель с именем talk.

Проблема может быть решена с добавлением создания модели talk в один из файлов миграции.

Answer 3

Эта ошибка ударила меня, когда я редактировал файл миграции, но не заметил, что я разместил один AddField() для поля до того, как была создана модель для этого поля. Может быть, помогает кому-то.
