Я пытаюсь построить четыре сущности с помощью Doctrine Symfony 2.
Один из объектов имеют «перекрывающий или пересекаемую Non первичного ключ составной ключ» - извиниться за мой плохой английский.
Я попытался изменить объект doctrine, но я все еще не могу сохранить все объекты PostgreSQL.
Ниже доктрины объектов четырех сущностей я построил:Overlapped Non Первичного ключ для составного ключ Учения Symfony 2

Таблица "geography_city" имеют две внешние ключи.
Один из них относится к таблице «geography_country» со столбцом «country_id».
Другое относится к таблице «geography_province» с двумя столбцами «country_id» и «province_id», колонка «провинция» является необязательной и может иметь значение NULL (подписанное как «MATCH SIMPLE» FOREIGN KEY), потому что, возможно, «Город страны» есть провинция.

Я ожидаю, что значение столбца «country_id» будет предоставлено автоматически при вставке в таблицу «geography_city», но на основании ошибок выше этого нет.
Любая помощь, которую я действительно ценю.
Большое спасибо.
С наилучшими пожеланиями.
Что не работает? У вас есть сообщение об ошибке? –
Почему бы вам не использовать целое число в качестве идентификатора в каждой таблице? Я думаю, что это будет проще использовать в качестве основного и внешнего ключей во всех ваших таблицах. –
Пожалуйста, добавьте сообщения об ошибке в свой вопрос и удалите их из комментариев, их будет легче читать. –
