我在Django探索表单集的机制。以下是我所做工作的要点：

创建了一个示例choicefield表单

forms.py

      from django import forms

      MONTH_CHOICES = (("JANUARY", "January"),
                       ("FEBRUARY", "February"),
                       ("MARCH", "March"),
                       ("DECEMBER", "December"),)

      class NameForm(forms.Form):
            your_name = forms.ChoiceField(label="Your Name",choices=MONTH_CHOICES)

    from django.shortcuts import render
    from django.http import HttpResponseRedirect,HttpResponse
    from django.forms.formsets import formset_factory
    from .forms import NameForm

    def index(request):
        lfs = formset_factory(NameForm)
        if request.method == 'POST':
            postedformset = lfs(request.POST)
            if postedformset.is_valid():
                for formz in postedformset:
                    print formz.cleaned_data['your_name']
            return HttpResponseRedirect('/polls/thanks/')
        else:
            form = NameForm()
                return render(request,'name.html',{'form':lfs})

    def thanks(request):
        return HttpResponse('Form filled. Thanks!')

添加了带有表单集实例的视图代码，用于NameForm和数据处理

视图.py

      from django import forms

      MONTH_CHOICES = (("JANUARY", "January"),
                       ("FEBRUARY", "February"),
                       ("MARCH", "March"),
                       ("DECEMBER", "December"),)

      class NameForm(forms.Form):
            your_name = forms.ChoiceField(label="Your Name",choices=MONTH_CHOICES)

    from django.shortcuts import render
    from django.http import HttpResponseRedirect,HttpResponse
    from django.forms.formsets import formset_factory
    from .forms import NameForm

    def index(request):
        lfs = formset_factory(NameForm)
        if request.method == 'POST':
            postedformset = lfs(request.POST)
            if postedformset.is_valid():
                for formz in postedformset:
                    print formz.cleaned_data['your_name']
            return HttpResponseRedirect('/polls/thanks/')
        else:
            form = NameForm()
                return render(request,'name.html',{'form':lfs})

    def thanks(request):
        return HttpResponse('Form filled. Thanks!')

3.用于实现表单集的HTML，以及用于添加和删除表单的javascript

name.html

<html>
<head>
    <title>DJANGO - First Forms</title>
</head>
<body>
    <form action="/polls/" method="POST">
        {{ form.management_form }}      
        <div class="link-formset">
            {{ form }}
        </div>
        <input type="Submit"/>
    </form>
</body>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery.formset/1.2.2/jquery.formset.min.js"></script>
<script>
    $('.link-formset').formset({
        addText: 'add link',
        deleteText: 'remove'
    });
</script>

他被处决了。Querydict from request.POST具有表单集中所有表单的选项（请参阅更新）

请分享你的想法

PS：我确实检查了诸如和之类的问题，但仍然无法找到根本原因

更新

对于我的表单集中的两个表单，当我尝试打印request.POST时，获得了下面的QueryDict，其中包含来自两个表单的信息

<QueryDict: {u'form-1-form-TOTAL_FORMS': [u''],  u'form-1-form-MIN_NUM_FORMS': [u''], u'form-1-form-MAX_NUM_FORMS': [u''],   u'form-1-form-INITIAL_FORMS': [u''], u'form-MAX_NUM_FORMS': [u'1000', u'1000'],   u'form-1-your_name': [u'FEBRUARY'], u'form-0-your_name': [u'FEBRUARY'],   u'form-MIN_NUM_FORMS': [u'0', u'0'], u'form-INITIAL_FORMS': [u'0', u'0'],   u'form-TOTAL_FORMS': [u'2', u'1']}>
