Django 电子邮件出现错误“'list' 对象没有属性 'splitlines'”

Question

我认为这是我的电子邮件发送代码：

def send_email():
    if dasa == 1:
        send_mail(
            'Test available',
            available_tests,
            'from_email',
            ['to_email'],
            fail_silently=False,
        )

当我在网站上运行时，我得到了这个错误：

我该如何解决？我直接从 django 教程中获取了说明，所以我不知道为什么它不起作用。我也找不到任何关于这个 'splitlines' 属性的信息。

Django 的 send_email 需要一个字符串作为消息参数。所以你需要申请例如join 首先在 available_tests 列表变量上。根据变量的结构，一个简单的 "\n".join(available_tests) 就足够了。或者 <br> 如果您有 HTML 消息。
