Когда я хочу зарегистрировать нового пользователя в Django, я получаю следующее предупреждение:
UNIQUE constraint failed: polls_usuario.matriculaUsuario
Когда я редактирую реестр, как администратором, так и в главном представлении, эта ошибка не возникает.Эта ошибка возникает только при создании нового пользователя.Когда я создаю пользователя с помощью регистра просмотра, создается пользователь с регистрацией по умолчанию.Когда я пытаюсь создать администратором, пользователь даже не создается.Что может происходить?

user = form.save(commit=False)
user.refresh_from_db() # load the profile instance created by the signal
user.usuario.matriculaUsuario = form.cleaned_data.get('matriculaUsuario')
usuario_form.save()
user.save()
raw_password = form.cleaned_data.get('password1')
user = authenticate(username=user.username, password=raw_password)
