PHP的表单括号技巧是Django的___？ [英] PHP's form bracket trick is to Django's ___?

问题描述

在PHP中，您可以创建名称如下的表单元素：

In PHP you can create form elements with names like:

category[1]
category[2]

甚至

category[junk]
category[test]

发布，类别会自动变成一个不错的字典，如：

When the form is posted, category is automatically turned into a nice dictionary like:

category[1] => "the input value", category[2] => "the other input value"

有没有办法在Django中做到这一点？ request.POST.getlist 不太正确，因为它只是返回一个列表，而不是字典。我也需要钥匙。

Is there a way to do that in Django? request.POST.getlist isn't quite right, because it simply returns a list, not a dictionary. I need the keys too.

推荐答案

你可以使用 django.utils.datastructures.DotExpandedDict 输入命名类别.1，category2等做类似的事情，但是我不明白为什么你会有必要验证并重新显示你收到的信息，当使用django.forms.Form将做一切您 - 适当的字段将为您调用 getlist 方法，前缀参数可用于重复使用相同的表单次。

You could use django.utils.datastructures.DotExpandedDict with inputs named category.1, category.2 etc. to do something similar, but I don't really see why you would if you ever have to validate and redisplay the information you're receiving, when using a django.forms.Form will do everything for you - appropriate fields will call the getlist method for you and the prefix argument can be used to reuse the same form multiple times.
