Я пытаюсь сделать какой-то рабочий портал. Я хочу, чтобы один пользователь мог применить к различным заданиям, но не к одному. Если один пользователь применил одно задание, он не может подать заявку на другой. Это проблема, и с помощью моей логики, когда я запустить вид я получилIntegrityError: (1062, "Duplicate for key 'user_id'")
«integrityerror»
. Пожалуйста, помогите мне. Спасибо
