How do I explicitly specify language of email I want to send? - email

Question

I have a custom user model that have a preferred_language field. I want all the emails (activation and password reset) to be sent translated to the language that user specified in profile.
class CustomUser(AbstractBaseUser, PermissionsMixin):
...
LANGUAGE_CHOICES = (
(1, "English"),
(2, "Русский")
)
preferred_language = models.PositiveSmallIntegerField(choices=LANGUAGE_CHOICES, default=2,
verbose_name=_("Preferred language"))
I thought about setting custom email class but didn't saw in navive djoser's classes any points where I could explicitly set the language of outcome emails despite of ready-to-be-translated style of email templates:
class ActivationEmail(BaseEmailMessage):
template_name = 'email/activation.html'
def get_context_data(self):
context = super(ActivationEmail, self).get_context_data()
user = context.get('user')
context['uid'] = utils.encode_uid(user.pk)
context['token'] = default_token_generator.make_token(user)
context['url'] = settings.ACTIVATION_URL.format(**context)
return context
Reset password view (which's refference is settings.EMAIL.activation used in ActivationEmail class above):
class ResetPassword(ActionViewMixin, generics.GenericAPIView):
...
def send_password_reset_email(self, user):
context = {'user': user}
to = [get_user_email(user)]
settings.EMAIL.password_reset(self.request, context).send(to)
def send_activation_email(self, user):
context = {'user': user}
to = [get_user_email(user)]
settings.EMAIL.activation(self.request, context).send(to)

In your case I would use the override context manager that stores the current language on enter (in order to sent the email) and restores it on exit.
from django.utils import translation
def send_password_reset_email(self, user):
context = {'user': user}
to = [get_user_email(user)]
lang_code = user.lang_code # retrieve user's language code here
with translation.override(lang_code):
settings.EMAIL.password_reset(self.request, context).send(to)
def send_activation_email(self, user):
context = {'user': user}
to = [get_user_email(user)]
lang_code = user.lang_code # retrieve user's language code here
with translation.override(lang_code):
settings.EMAIL.activation(self.request, context).send(to)
