Django等价于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，我将这样做以名称作为数组。

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

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

或者如果我想获得名称一个关联数组：

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

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

Django等同于这样的东西是什么？

What is the Django equivalent for such things?

推荐答案

检查查询QueryDict文档，特别是使用 QueryDict.getlist（key） 。

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

由于request.POST和request.GET在视图中是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>

然后这样：

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