我到处找遍了，但没能解决。我的页面上有一个表格集(表格在底部)。当我使用ajax按“保存”按钮时，需要保存主窗体和窗体集。已发送POST请求，但存在错误。

错误"POST /new/ HTTP/1.1“500 59

ValidationError: U‘’ManagementForm数据丢失或已被篡改“”

Views.py

def master_detail_new(request):
    if request.method == 'GET':
    author = TmpPlInvoice()
    author_form = TmpForm(instance=author)
    BookFormSet = inlineformset_factory(TmpPlInvoice, TmpPlInvoicedet,
                                        exclude=('emp_id', 'voucher', 'lineitem', 'id',),
                                        form=TmpFormDetForm, )
    formset = BookFormSet(instance=author)
    return render(request, 'main.html',
                  {'form': author_form, 'formset': formset, 'formtotal': totalform, 'postform': postform},
                  )

    elif request.method == 'POST':
    def get_new_voucher_id():
        temp_vid = TmpPlInvoice.objects.order_by().values_list("voucher_id", flat=True).distinct()
        if not temp_vid:
            voucher_id = str(1).zfill(4)
        else:
            voucher_id = str(int(max(temp_vid)) + 1).zfill(4)
        return voucher_id

    author_form = TmpForm()
    author = TmpPlInvoice()
    BookFormSet = inlineformset_factory(TmpPlInvoice, TmpPlInvoicedet, exclude=('emp_id', 'voucher', 'lineitem', 'id',),
                                        form=TmpFormDetForm, extra=2)
    formset = BookFormSet(instance=author)
    voucher_id = get_new_voucher_id()
    author = TmpForm(request.POST)
    if author.is_valid():
        created_author = author.save(commit=False)
        created_author.voucher_id = voucher_id
        created_author.save()

        formset = BookFormSet(request.POST, instance=created_author)
        if formset.is_valid():
            formset.save()
        return HttpResponseRedirect('/')

 <div class="x_content">
    {{ formset.management_form }}
    {{ formset.non_form_errors.as_ul }}
     <table class="table table-striped responsive-utilities jambo_table   bulk_action form"
   id="formset" style="background-color:#d0ffff;">
       <thead style="background-color:#9df0e0;;color: #73879C">
{% for form in formset.forms %}
    {% if forloop.first %}
    <thead>
    <tr class="headings">
        {% for field in form.visible_fields %}
        <th>{{ field.label|capfirst }}</th>
        {% endfor %}
    </tr>
    </thead>
    {% endif %}

Javascript发送数据

$("#save").click(function() {
    $.ajax({
      type:'POST',
        url:'/new/',
        data:{
            csrfmiddlewaretoken:$('input[name=csrfmiddlewaretoken]').val()
        },
        success:searchSuccess,
        dataType: 'html'
    });
   });

function searchSuccess(data, textStatus, jqXHR)
  {
    $('#myForm').html(data);
   }

我做错什么了？任何帮助都将不胜感激。多模板集

编辑I不更改窗体集的数量。我的CSRF运转良好。而且，如果没有ajax，我也会遇到同样的问题。

 <input id="id_tmpplinvoicedet_set-TOTAL_FORMS" name="tmpplinvoicedet_set-TOTAL_FORMS" type="hidden" value="3" />
 <input id="id_tmpplinvoicedet_set-INITIAL_FORMS" name="tmpplinvoicedet_set-INITIAL_FORMS" type="hidden" value="0" />
 <input id="id_tmpplinvoicedet_set-MIN_NUM_FORMS" name="tmpplinvoicedet_set-MIN_NUM_FORMS" type="hidden" value="0" />
 <input id="id_tmpplinvoicedet_set-MAX_NUM_FORMS" name="tmpplinvoicedet_set-MAX_NUM_FORMS" type="hidden" value="1000" />

如果表单数量在发送到浏览器后发生了更改，则此错误将由窗体集引发。表单集使用management_form中名为management_form的隐藏输入字段来跟踪该数字。来自文档

它用于跟踪显示了多少表单实例。如果要通过JavaScript添加新表单，也应该在此表单中增加计数字段。

这就是我如何更改每个表单的TOTAL_FORMS。注意*当向页面动态添加表单时，我传入一个表单作为所有HTML和正则表达式的ID。

其中一个是我调用的add按钮：

addForm: function () {
    this.count++
    let form_count = this.count
    form_count++

    let formID = 'id_form-' + this.count

    incremented_form = this.vue_form.replace(/form-\d/g, 'form-' + this.count)
    this.formList.push(incremented_form)
    this.$nextTick(() => {
        let total_forms = document.getElementsByName('form-TOTAL_FORMS').forEach
        (function (ele, idx) {
            ele.value = form_count
            })
        })
},
