Django具有相同名称的多个输入字段值 [英] Django multiple input field values with same name

问题描述

我需要一些帮助。如何使用同一个名称处理多个输入字段值的表单？只有一次查看，这实际上是基本问题的形式..另一​​个想法，我发现这种方法从

如何我处理这一切吗？目前，我正在使用< input type =radio... ，但是如果一次使用相同的名称，它将无法正常工作。但是如果我使用：< input type =checkbox... ，答案可以一次检查超过1个问题...

也许这样：

 < input type =radioname =answer- {{question.id}}> 
  

如何在视图中获得所有这些？

已解决

在我的测试中：

  {％在问题中的问题％} 
< input type =hiddenname =questionvalue ={{question.id}} /> 
 
 {％for question.get_answers％} 
< input type =radioname =answer  -  {{question.id}}value = {{answer.score}}> 
 {％endfor％} 
 {％endfor％} 
  

views.py

  questions = request.POST.getlist（'question'）
答案= [request.POST ['answer  -  {}'。format（q）] for q in questions] 
  

其结果：

  ['20'，'19'，'16'，'13' ，'11'，'10'，'9'，'8'，'1'] 
 ['5'，'2'，'3' '4'，'2'，'2'] 
  

解决方案

如果我理解你，你需要实现多项选择？
那么你可以在你的模板中做到这一点：

  {％for answer in answers％} 
< input type =checkboxname =answerid =answer {{forloop.counter}}value ={{answer.id} }> 
 {％endif％} 
  

Andi在视图中：

  answer = request.POST.getlist（'answer'）
 for el in answer：
 pass 
  

I need some help. How can I handle the form ,with multiple input field values, with same name? and only once view, this actually for basic questions form.. another idea I found this method from https://stackoverflow.com/a/478406/6396981:

relations = request.POST.getlist('relations')

How do I handle it all? Currently I'm doing it with <input type="radio"..., but of course it couldn't work if it has same name in once form. But if I use: <input type="checkbox"..., the answers can be check more than 1 in once question...

Maybe like this:

<input type="radio" name="answer-{{ question.id }}">

How can I get it all in the view?

Solved:

In my test:

{% for question in questions %}
    <input type="hidden" name="question" value="{{ question.id }}/>

    {% for answer in question.get_answers %}
        <input type="radio" name="answer-{{ question.id }}" value={{ answer.score }}>
    {% endfor %}
{% endfor %}

views.py

questions = request.POST.getlist('question')
answers = [request.POST['answer-{}'.format(q)] for q in questions]

And the results of it:

['20', '19', '16', '13', '11', '10', '9', '8', '1']
['5', '2', '3', '4', '1', '4', '4', '2', '2']

解决方案

If I understood you right you need to implement multiple choice? Then you can do in your template this:

{% for answer in answers %}
    <input type="checkbox" name="answer" id="answer{{ forloop.counter }}" value="{{ answer.id }}">
{% endif %}

Andi in view:

answer = request.POST.getlist('answer')
for el in answer:
    pass
