python - 获取 Django View 中的复选框列表

Question

我的模板中有这段代码:

{% for email in emails %}
  {%if email%}
     <input type="checkbox" name="email" value="{{email}}" /> {{email}}<br />
  {% endif %}
{% endfor %}

所以模板中的输出是:

email1@sample.com
email2@sample.com
email3@sample.com
...

在我看来，我为此打印了我的 request.POST。

print request.POST
print request.POST['email']
for email in request.POST['email']:
 print email

我得到了这个输出:

<QueryDict: {u'email': [u'email1@sample.com', u'email2@sample.com', u'email3@sample.com'], ..., u'csrfmiddlewaretoken': [u'05e5bdb542c3be7515b87e8160c347a0', u'05e5bdb542c3be7515b87e8160c347a0']}>
email3@sample.com
e
m
a
i
l
3
@
s
a
m
p
l
e
.
c
o
m

我的问题是，如何在我的 View 中获取电子邮件列表？ 我希望输出是这样的..

email1@sample.com
email2@sample.com
email3@sample.com
...

使用 request.POST.getlist :

Returns the data with the requested key, as a Python list. Returns an empty list if the key doesn’t exist and no default value was provided. It’s guaranteed to return a list of some sort unless the default value provided is not a list.
