Я прочитал каждую тему об этой ошибке, и я не могу понять, откуда это происходит.Преобразование массива в строку ArrayChoiceList
У меня есть форма с большим количеством полей флажка, которые заполняются из массивов. Однако в моем Entity я конвертирую все поля в строку, разделенную запятыми (да, я знаю, это уродливо), и все поля, о которых идет речь, работают нормально, однако я получаю эту ошибку, и я просто не могу понять, где проблема исходит из. Когда я отлаживал эти поля, он дал мне массивы, которые были под вопросом, и я смог их исправить.
У меня также есть еще 4 набора списков выбора EntityType, которые заполняются из 4 других таблиц базы данных. Все данные тянутся и работают правильно для всех Entities, но когда я пытаюсь сохранить базу данных, я получаю эту ошибку, но я не могу найти ссылку на то, что относится к Entity или array/field. Все, что я вижу ниже, - это пустые массивы.
Если вы видите мою Entity и FormType, я могу опубликовать их.
