我在使用 django 的表单集时遇到了问题，当我只有一个表单集时，来自 POST 的数据被存储了，但是在我添加了第二个表单集之后，我只得到了每个表单集的最后一个输入。以下是表格：

class OperationsForm( forms.Form ):
    operation = forms.CharField(
        required = True,
        max_length = 20,
        widget = forms.TextInput( attrs = {
            'placeholder':'Operation Name'
            } ),
    )
class DataTypesForm( forms.Form ):
field = forms.CharField(
        required = True,
        max_length = 20,
        widget = forms.TextInput( attrs = {
            'placeholder':'Field Name'
        } ),
)
type = forms.CharField(
        required = True,
        max_length = 20,
        widget = forms.TextInput( attrs = {
            'placeholder':'Field Type'
        } ),
)

这是views.py：

    def index( request ):
     OperationsFormSet = formset_factory( OperationsForm )
     DataTypesFormSet = formset_factory( DataTypesForm )

if request.method == 'POST':
    operations_formset = OperationsFormSet( request.POST, prefix='operations' )
    data_formset = DataTypesFormSet( request.POST, prefix='datas' )

    if operations_formset.is_valid() and data_formset.is_valid():
        operations_list = []

        for operation_form in operations_formset:
            operation = operation_form.cleaned_data.get( 'operation'
            if operation:
                print( operation )
                operations_list.append( operation )
        operations = ' '.join(operations_list)
        operations = "\"" + operations + "\""

        data_list = []

        for data in data_formset:
            dataName = data.cleaned_data.get( 'field' )
            dataType = data.cleaned_data.get( 'type' )
            if dataType and dataName:
                dataToAdd = dataName + '-' + dataType
                data_list.append( dataToAdd )
        datas = ' '.join( data_list )
        datas = "\"" + datas + "\""

        print( "%s" % operations )
        print( "%s" % datas )
        #Do Something 
        return response
else:
    operations_formset = OperationsFormSet( prefix='operations' )
    data_formset = DataTypesFormSet( prefix='datas' )

context = { 'operations_formset': operations_formset, 'data_formset': data_formset }

return render( request, 'arquetipo/index.html', context )

这是 index.html

    <div class="maven-arguments">
        <div class="row">
            <div class="operations">
                {% for f_form in operations_formset %}
                    <div class="operation-formset">
                        {{ f_form.as_table }}
                    </div>
                {% endfor %}
                {{ operations_formset.management_form }}
            </div>

            <div class="data">
                {% for d_form in data_formset %}
                    <div class="data-formset">
                        {{ d_form.as_table }}
                    </div>
                {% endfor %}
                {{ data_formset.management_form }}
            </div>
    </div>
</div>
</br>
    <button types='submit' value='generate'>Generar</button>
</form>

任何人都可以帮助我吗？

谢谢你。

更新：

我忘了提到我使用 JS 在运行时添加或删除额外的字段，这是代码：

    <script>
       $('.operation-formset').formset({
        addText: 'Add operation',
        deleteText: 'Delete'
    });
       $('.data-formset').formset({
        addText: 'Add a field',
        deleteText: 'Delete'
    });
  </script>
