我想发送html电子邮件,使用Django模板,像这样:

<html>
<body>
hello <strong>{{username}}</strong>
your account activated.
<img src="mysite.com/logo.gif" />
</body>

我找不到任何关于send_mail的东西,django-mailer只发送HTML模板,没有动态数据。

如何使用Django的模板引擎生成电子邮件?


当前回答

使用EmailMultiAlternatives和render_to_string来使用两个可供选择的模板(一个是纯文本,一个是html):

from django.core.mail import EmailMultiAlternatives
from django.template import Context
from django.template.loader import render_to_string

c = Context({'username': username})    
text_content = render_to_string('mail/email.txt', c)
html_content = render_to_string('mail/email.html', c)

email = EmailMultiAlternatives('Subject', text_content)
email.attach_alternative(html_content, "text/html")
email.to = ['to@example.com']
email.send()

其他回答

我创建了Django Simple Mail,为你想发送的每一封事务性电子邮件提供了一个简单的、可定制的和可重用的模板。

邮件内容和模板可以直接从django的管理编辑。

在你的例子中,你会注册你的电子邮件:

from simple_mail.mailer import BaseSimpleMail, simple_mailer


class WelcomeMail(BaseSimpleMail):
    email_key = 'welcome'

    def set_context(self, user_id, welcome_link):
        user = User.objects.get(id=user_id)
        return {
            'user': user,
            'welcome_link': welcome_link
        }


simple_mailer.register(WelcomeMail)

然后用这种方式发送:

welcome_mail = WelcomeMail()
welcome_mail.set_context(user_id, welcome_link)
welcome_mail.send(to, from_email=None, bcc=[], connection=None, attachments=[],
                   headers={}, cc=[], reply_to=[], fail_silently=False)

我很乐意得到任何反馈。

在Django 1.7的send_email方法中加入了html_message参数。

html_message:如果提供了html_message,生成的电子邮件将是 多部分/可选的电子邮件,以消息作为文本/纯内容 Type和html_message作为文本/html内容类型。

所以你可以:

from django.core.mail import send_mail
from django.template.loader import render_to_string


msg_plain = render_to_string('templates/email.txt', {'some_params': some_params})
msg_html = render_to_string('templates/email.html', {'some_params': some_params})

send_mail(
    'email title',
    msg_plain,
    'some@sender.com',
    ['some@receiver.com'],
    html_message=msg_html,
)

send_emai()不适合我,所以我在django docs中使用EmailMessage。

我有两个版本的答案:

只提供html电子邮件版本 与纯文本电子邮件和html电子邮件版本

from django.template.loader import render_to_string 
from django.core.mail import EmailMessage

# import file with html content
html_version = 'path/to/html_version.html'

html_message = render_to_string(html_version, { 'context': context, })

message = EmailMessage(subject, html_message, from_email, [to_email])
message.content_subtype = 'html' # this is required because there is no plain text email version
message.send()

如果你想包含一个纯文本版本的电子邮件,修改如下:

from django.template.loader import render_to_string 
from django.core.mail import EmailMultiAlternatives # <= EmailMultiAlternatives instead of EmailMessage

plain_version = 'path/to/plain_version.html' # import plain version. No html content
html_version = 'path/to/html_version.html' # import html version. Has html content

plain_message = render_to_string(plain_version, { 'context': context, })
html_message = render_to_string(html_version, { 'context': context, })

message = EmailMultiAlternatives(subject, plain_message, from_email, [to_email])
message.attach_alternative(html_message, "text/html") # attach html version
message.send()

我的普通和html版本是这样的: plain_version.html:

Plain text {{ context }}

html_version.html

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
 <head>
 ...
 </head>
<body>
<table align="center" border="0" cellpadding="0" cellspacing="0" width="320" style="border: none; border-collapse: collapse; font-family:  Arial, sans-serif; font-size: 14px; line-height: 1.5;">
...
{{ context }}
...
</table>
</body>
</html>

我喜欢使用这个工具,允许轻松地发送电子邮件HTML和TXT与简单的上下文处理:https://github.com/divio/django-emailit

使用EmailMultiAlternatives和render_to_string来使用两个可供选择的模板(一个是纯文本,一个是html):

from django.core.mail import EmailMultiAlternatives
from django.template import Context
from django.template.loader import render_to_string

c = Context({'username': username})    
text_content = render_to_string('mail/email.txt', c)
html_content = render_to_string('mail/email.html', c)

email = EmailMultiAlternatives('Subject', text_content)
email.attach_alternative(html_content, "text/html")
email.to = ['to@example.com']
email.send()
