Django和HTML数组 [英] Django and HTML arrays

问题描述

我有一个表单与这个输入：

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

当我提交，我如何将该html数组分配给一个变量，因为request.POST.getlist （'person'）不工作，我一直在检查其他帖子，但是我发现唯一没有任何有用的东西

THEAD

我希望有人可以帮我弄清楚，因为阅读文档，并且做得很顺利...

事实是，我有一个桌子在我的数据分析中有折扣...每个折扣都有一个默认值...所以我做了

  discounts = Discount.objects.all（）
 
 {％for i in discounts％} 
< input name =discount [{{i.id} }]value ={{i.default_value}}> 
 {％endfor％} 
  

在我没有任何方法来捕获该HTML数组我发送...任何建议？

解决方案

对不起，回答这样一个老问题，但我坚持一样问题，没有找到任何可接受的答案。所以，这是我的解决方案：

  def get_post_dict（post，key）：
 result = {} 
如果发布：
 import re 
 patt = re.compile（'^（[a-zA-Z_] \w +）\ [（[a-zA-Z_\  - ] [\\ $'$'）
 for post_name，post.items（）中的值：
 value = post [post_name] 
 match = patt.match（post_name ）
如果不匹配或不是值：
 continue 
 name = match.group（1）
如果name == key：
k = match.group（2） 
 result.update（{k：value}）
返回结果
  

现在你可以这样使用：

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

或

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

I have a form with this inputs:

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

when I submit, how can i assign that html array to a variable, cause request.POST.getlist('person') doesn't work, i been checking for other post but the only one i found doesn't have anything usefull

THEAD

I hope someone could help me figure it out, cause a read the doc, and did quite get the way to do it...

the thing is that i have a table in my db with discounts... where every discount has a default value... so i made it

discounts = Discount.objects.all( )

{% for i in discounts %} 
<input name="discount[{{ i.id }}]" value="{{ i.default_value }}"> 
{% endfor %}

and on my i dont have any method to catch that html array i'm sending... any suggestions?

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

Now you can use it like this:

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

or

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