问题描述

我有一个表格与此输入：

I have a form with this inputs:

<input name="person[name]" value="">
<input name="person[surname]" value="">

推荐答案

对不起，回答这样一个老问题，但我还是坚持了同样的问题，并没有发现任何可以接受的答案。所以，这里是我的解决方案：

Sorry for answering such an old question, but i stuck with the same problem and didn't found any acceptable answers for it. So, here is my solution:

def get_post_dict(post, key):
    result = {}
    if post:
        import re
        patt = re.compile('^([a-zA-Z_]\w+)\[([a-zA-Z_\-][\w\-]*)\]$')
        for post_name, value in post.items():
            value = post[post_name]
            match = patt.match(post_name)
            if not match or not value:
                continue
            name = match.group(1)
            if name == key:
                k = match.group(2)
                result.update({k:value})
    return result

现在你可以使用这样的：

Now you can use it like this:

persons = get_post_dict(request.POST, 'person')
...

或

django.http.QueryDict.getdict = get_post_dict
persons = request.POST.getdict('person')
