Я использую форму Authentication
по умолчанию из Django.
Это реализация по умолчанию Django из AuthenticationForm:
from django.contrib.auth.forms import AuthenticationForm
Я перевел сообщение об ошибке по умолчанию error_messages на испанский:
error_messages = {
'invalid_login': _(
"- Por favor, ingrese un nombre de usuario y contraseña correctos. "
"- Diferencie entre minúsculas y mayúsculas."
),
Однако, когда приложение загружено в производство (Heroku), эти изменения не видны (похоже, оно было применено только локально).
Почему?
