请提出解决方法。

Answer 1

您的 send_mail 参数与要求的参数不匹配（参见 https://docs.djangoproject.com/en/3.2/topics/email/#quick-example）。

我认为您需要使用表单中的数据构建邮件正文。您可以将表单值合并到一个新字符串中，然后发送电子邮件。


email_body = '{name}\n\n    {phone} - {email} - {address} \n\n {message}'.format(**form_data))

send_mail(
    subject,
    email_body,
    'mail@domain.com', # from Email
    ['toemail@gmail.com',], # To email  
)
