Djoser更改邮件语言

Question

有没有办法根据用户实例的语言更改在djoser中发送的电子邮件？我已经找到了这个问题How do I explicitly specify language of email I want to send?，但它似乎不是一个选项在最新版本的djoser，因为不再有每个操作(激活，重置密码等)的视图。或者我还没有弄清楚它是如何工作的。此外，我还尝试继承UserViewSet类并应用转换，但我不知道这是否是执行此操作的方法，以及如何指定djoser的所有urls。

class UserViewSet(djoser_view.UserViewSet):
    def perform_create(self, serializer):
        user = serializer.save()
        signals.user_registered.send(
            sender=self.__class__, user=user, request=self.request
        )

        context = {"user": user}
        to = [get_user_email(user)]
        language = user.language or 'en-us'
        with translation.override(language):
            if settings.SEND_ACTIVATION_EMAIL:
                settings.EMAIL.activation(self.request, context).send(to)
            elif settings.SEND_CONFIRMATION_EMAIL:
                settings.EMAIL.confirmation(self.request, context).send(to)

    def perform_update(self, serializer):
        super().perform_update(serializer)
        user = serializer.instance
        language = user.language or 'en-us'
        with translation.override(language):
            if settings.SEND_ACTIVATION_EMAIL:
                context = {"user": user}
                to = [get_user_email(user)]
                settings.EMAIL.activation(self.request, context).send(to)


    @action(["post"], detail=False)
    def activation(self, request, *args, **kwargs):
        serializer = self.get_serializer(data=request.data)
        serializer.is_valid(raise_exception=True)
        user = serializer.user
        user.is_active = True
        user.save()

        signals.user_activated.send(
            sender=self.__class__, user=user, request=self.request
        )

        language = user.language or 'en-us'
        with translation.override(language):
            if settings.SEND_CONFIRMATION_EMAIL:
                context = {"user": user}
                to = [get_user_email(user)]
                settings.EMAIL.confirmation(self.request, context).send(to)

        return Response(status=status.HTTP_204_NO_CONTENT)

有没有人有什么建议或者已经这么做了？

你当然可以！

您正确地识别了发送邮件的操作。

    @action(["post"], detail=False)
    def activation(self, request, *args, **kwargs):
        serializer = self.get_serializer(data=request.data)
        serializer.is_valid(raise_exception=True)
        user = serializer.user
        user.is_active = True
        user.save()

        signals.user_activated.send(
            sender=self.__class__, user=user, request=self.request
        )

        if settings.SEND_CONFIRMATION_EMAIL:
            context = {"user": user}
            to = [get_user_email(user)]
            settings.EMAIL.confirmation(self.request, context).send(to)

因此，在继承UserViewSet子类之后，您可以在activation操作中提供一个模板名称。

        if settings.SEND_CONFIRMATION_EMAIL:
            context = {"user": user}
            to = [get_user_email(user)]
            kwargs = {"request": self.request, "context": context}
            if user.country == "Country1":
                kwargs["template_name"] = "email/country1/activation.html"
            settings.EMAIL.confirmation(**kwargs)).send(to)

Djoser正在使用templated-mail创建邮件内容。

但是，如您所见，user实体是在上下文中传递的。因此，我建议您稍微调整一下设置，在负责生成此电子邮件的类中执行此操作。

在你的app/email.py中

class CountryActivationMail(ActivationEmail):
    def __init__(self, **kwargs):
        super().__init__(**kwargs)
        if self.context.user.country == "Country1":
            self.template_name = "email/country1/activation.html"

并按照in the docs.的说明在djoser设置中设置CountryActivationMail
