在 Django 视图中获取复选框帖子列表 [英] get the list of checkbox post in django views

问题描述

我的模板中有此代码:

{% 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:

[e-mail]
[e-mail]
[e-mail]
...

在我的视图中，我打印了关于此的 request.POST.

in my views I printed my request.POST about this.

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'[e-mail]', u'[e-mail]', u'[e-mail]'], ..., u'csrfmiddlewaretoken': [u'05e5bdb542c3be7515b87e8160c347a0', u'05e5bdb542c3be7515b87e8160c347a0']}>
[e-mail]
e
m
a
i
l
3
@
s
a
m
p
l
e
.
c
o
m

我的问题是，如何在我的视图中获取电子邮件列表?我希望输出是这样的..

my question is, how can I get the list of emails in my views? I wanted the output will be like this..

[e-mail]
[e-mail]
[e-mail]
...

推荐答案

使用 request.POST.getlist:

返回带有请求键的数据，作为 Python 列表.如果键不存在且未提供默认值，则返回一个空列表.除非提供的默认值不是列表，否则保证返回某种列表.

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.
