Добрый день!
У нас есть TPT-наследование в нашей модели данных EF, основанное на наборе представлений и хранимых процедур в базе данных. Существует базовая сущность Tag , которая НЕ является абстрактной и имеет первичный ключ TtrId, и унаследованная сущность FinancialGoal . Тег сущность, основанная на представлении vwTagTree, FinancialGoal основанная на представлении vwGoals. Оба представления имеют поле TtrId, реализующее отношение один к одному. Каждый объект связан с другими модельными объектами. Поле TtrId объекта Tag имеет атрибут StoreGeneratedPattern = Identity, но оно не участвует ни в какой ассоциации в качестве зависимого поля.
Однако мы получаем ошибку " Зависимое свойство в ReferentialConstraint отображается в столбец, созданный магазином. Столбец: 'TtrId'. " при попытке добавить объект FinancialGoal, Выбор в порядке, обновление в порядке, вставка Tag объекта в порядке, но вставка FinancialGoal объекта вызывает упомянутую ошибку.
Вот часть схемы модели EF:
К сожалению, я не могу опубликовать скриншот из-за низкой репутации, поэтому вот CSDL часть определения EDMX:
