оператор не существует: jsonb ~~ * неизвестная ошибка

1 голос
/ 18 февраля 2020

Я пытаюсь запустить эту строку кода. Это делает запрос sqlalchemy, который нечувствителен к регистру данных. precedent_query = and_(Db_obj.data.ilike(f"{{'collections': [{{'idType': {id_type}, 'externalId': {external_id}}}]}}"))

Документы в sqlalchemy, на которые я смотрел, не помогли мне понять, что означает часть ошибки jsonb ~~* unknown, разве она не знает, что такое jsonb? Я импортировал это. Или это ~~ *, что неизвестно?

Буду признателен за любую помощь или лучшее решение для этой версии без учета регистра (precedent_query = and_(Db_obj.data.contains({'collections': [{'idType': id_type, 'externalId': external_id}]})))

Моя ошибка
