Django 相当于 PHP 的表单值数组/关联数组 [英] Django equivalent of PHP's form value array/associative array

问题描述

在 PHP 中，我会这样做以获得 name 作为数组.

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

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

或者如果我想获得 name 作为关联数组:

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

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

什么是 Django 等价物?

What is the Django equivalent for such things?

推荐答案

查看 QueryDict 文档，特别是 QueryDict.getlist(key).

由于视图中的 request.POST 和 request.GET 是 QueryDict 的实例，您可以这样做:

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

<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>

然后是这样的:

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