当默认电子邮件被覆盖时，Djoser 不发送电子邮件

我有一个使用 Djoser 进行身份验证的 DRF 项目。该计划是覆盖 Djoser 的默认激活电子邮件并发送 HTML 模板电子邮件。这是我所拥有的：

# settings.py

DJOSER = {
    "SEND_ACTIVATION_EMAIL": True,
    "ACTIVATION_URL": "activate/{uid}/{token}",
    "EMAIL": {"activation": "base.emails.ActivationEmail"},
}

# base/emails

from django.contrib.auth.tokens import default_token_generator
from djoser import email, utils
from djoser.conf import settings


class ActivationEmail(email.ActivationEmail):
    template_name = "emails/activation.html"

    def get_context_data(self):
        # ActivationEmail can be deleted
        context = super().get_context_data()

        user = context.get("user")
        context["first_name"] = user.first_name
        context["uid"] = utils.encode_uid(user.pk)
        context["token"] = default_token_generator.make_token(user)
        context["url"] = settings.ACTIVATION_URL.format(**context)
        return context

# templates/emails/activation.html

{% extends "emails/base.html" %}

{% load static %}

{% block subject %}Account Activation on Dummy{% endblock %}

{% block heading %}
    Account Activation
{% endblock %}

{% block content %}
    You're receiving this email because you need to finish activation process.
    Please click on the button below to activate your account:

    <br><br><br>
    <a
        href="{{ url }}"
        target="_blank"
        style="
            text-decoration: none;
            font-family: lato, 'helvetica neue', helvetica, arial, sans-serif;
            font-size: 20px;
            color: #fff;
            background-color: #0b913a;
            padding: 10px 25px;
            border-radius: 5px;
        "
        >Activate</a
    >

一切似乎都正确，但电子邮件未发送。我检查收件箱，但什么也没有看到。但是当我删除指向自定义电子邮件的电子邮件设置时，它会发送默认的 Djoser 激活电子邮件。怎么了？

我只是将其与我的项目中使用 Djoser 的自定义激活电子邮件进行了比较，您的配置看起来非常相似。

In ActivationEmail有一个send方法。您可能想要覆盖它并添加一些日志。也许这会有所帮助。

    def send(self, to, *args, **kwargs):
        logger.info(f"Sending activation mail to {to}")
        try:
            super().send(to, *args, **kwargs)
        except:
            logger.exception(f"Couldn't send mail to {to}")
            raise
        logger.info(f"Activation mail sent successfully to {to}")

无论如何，写一个测试就可以了。在您的测试中，您可以检查电子邮件是否已使用发送

self.assertEqual(len(mail.outbox), 1)

where mail来自。

from django.core import mail
