python - Django CBV 方法从不同的 CBV 输出 HTML

Question

有没有办法在一个基于类的视图中创建一个方法，该方法能够在调用时输出另一个基于类的视图的 HTML？

伪代码看起来像这样：

class View1(ListView):
  def method(self, *args, **kwargs):
    return   # template.html output from View2

class View2(ListView):
  ...
  # normal ListView

Answer 1

您不使用 django 视图来创建电子邮件的 html 正文。为此，您可以使用render_to_string. 在此处阅读更多信息：

Answer 2

这是您可以使用的代码段：

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

def send_template_email(context, # variables for the templates
                        plain_text, # plain text template
                        html_part, # html template
                        subject, # the email subject
                        recipients, # a list of recipients
                        from_addr):

    plaintext = get_template(plain_text)
    html_part = get_template(html_part)
    ctx = Context(context)
    text_content = plaintext.render(ctx)
    html_content = htmly.render(ctx)
    msg = EmailMultiAlternatives(subject,text_content,from_addr,recipients)
    msg.attach_alternative(html_content,"text/html")
    msg.send(True)

从您的视图（或任何地方）调用它，如下所示：

plain_text = 'plain-text.txt'
html_part = 'html-email.html'
recipients = ['user@email.com']
from_addr = 'admin@domain.com'
subject = 'Your email'

variables = {'name': 'John Smith'}

send_template_email(variables,
                    plain_text,
                    html_part,
                    recipients,
                    from_addr,
                    subject)

plain-text.txt并且html-email.html应该在您TEMPLATE_DIRS所在位置的某个地方，这些是普通的 django 模板，因此plain-text.txt可以是：

Dear {{ name }},
   All you bases are belong to us!

Love,

Robot Overload

和html-email.html：

<p>Dear {{ name }},<br />
   All your bases are belong to <strong>us!</strong>
</p>
<hr />
<p>Love,<br />Robot <em>Overlord</em></p>
