获取django视图中的复选框帖子列表
问题描述:
我的模板中有这个代码:
I have this code in my template:
{% for email in emails %}
{%if email%}
<input type="checkbox" name="email" value="{{email}}" /> {{email}}<br />
{% endif %}
{% endfor %}
所以输出在模板中是:
email1@sample.com
email2@sample.com
email3@sample.com
...
在我的意见中,我打印了我的请求。
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

我的问题是,我如何得到电子邮件列表在我的意见?

email1@sample.com
email2@sample.com

...
答
使用请求。 POST.getlist :
以请求的密钥返回数据,作为Python列表。如果该键不存在并且没有提供默认值,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.
