Здравствуйте!
Данное задание было выдано преподавателем, вроде бы простое, но я довольно таки не лажу с базами данных.
Сначала я сделал добавление пользователей на сайт (через локальную БД), но когда я стал переключать на postgresql вылезла ошибка. По данной проблеме смотрел на разных сайтах ничего не помогло.
Проблема такова: Формат строки инициализации не соответствует спецификации, начиная с индекса 36 (Строка 16 - Контроллера)
Текст задания: (см.Вложения)
P.S: Пожалуйста не удивляйтесь названию проекта
