Django等价于PHP的表单值数组/关联数组

In PHP, I would do this to get name as an array.

在PHP中，我这样做是为了获得一个数组的名称。

<input type"text" name="name[]" />
<input type"text" name="name[]" />

Or if I wanted to get name as an associative array:

或者如果我想把名字作为一个关联数组:

<input type"text" name="name[first]" />
<input type"text" name="name[last]" />

What is the Django equivalent for such things?

对于这样的事情，Django是什么意思?

Check out the QueryDict documentation, particularly the usage of QueryDict.getlist(key).

查看QueryDict文档，特别是使用QueryDict.getlist(key)。

Since request.POST and request.GET in the view are instances of QueryDict, you could do this:

因为请求。邮报》和请求。GET in the view are instances of QueryDict，你可以这样做:

<form action='/my/path/' method='POST'>
<input type='text' name='hi' value='heya1'>
<input type='text' name='hi' value='heya2'>
<input type='submit' value='Go'>
</form>

Then something like this:

然后是这样的:

def mypath(request):
    if request.method == 'POST':
        greetings = request.POST.getlist('hi') # will be ['heya1','heya2']

Sorry for digging this up, but Django has an utils.datastructures.DotExpandedDict. Here's a piece of it's docs:

不好意思，我把它翻出来了，Django有一个utils. datastructuretures.dotexpandeddict。这里有一个文档:

>>> d = DotExpandedDict({'person.1.firstname': ['Simon'], \
        'person.1.lastname': ['Willison'], \
        'person.2.firstname': ['Adrian'], \
        'person.2.lastname': ['Holovaty']})
>>> d
{'person': {'1': {'lastname': ['Willison'], 'firstname': ['Simon']}, '2': {'lastname': ['Holovaty'], 'firstname': ['Adrian']}}}

The only difference being you use dot's instead of brackets.

唯一的区别是你使用点而不是括号。

EDIT: This mechanism was replaced by form prefixes, but here's the old code you can drop in your app if you still want to use this concept: https://gist.github.com/grzes/73142ed99dc8ad6ac4fc9fb9f4e87d60

编辑:这个机制已经被表单前缀所取代，但是如果您还想使用这个概念，可以在应用程序中插入一些旧代码:https://gist. github.com/grzes/73142ed99dc8ad4fc9fc9fb9ffb4e87d60

Django does not provide a way to get associative arrays (dictionaries in Python) from the request object. As the first answer pointed out, you can use .getlist() as needed, or write a function that can take a QueryDict and reorganize it to your liking (pulling out key/value pairs if the key matches some key[*] pattern, for example).

Django不提供从请求对象获取关联数组(Python中的字典)的方法。正如第一个答案指出的那样，您可以根据需要使用.getlist()，或者编写一个函数，它可以使用QueryDict并将其重新组织到您喜欢的地方(例如，如果键匹配某个关键的[*]模式)，就可以取出键/值对。
