管理表單數據丟失或已被篡改驗證表格

我已經遍地搜索，但我無法解決它。我的頁面中有一個formset（底部的表格）。當我使用ajax按下保存按鈕時，主窗體和formset需要保存。 POST請求已發送但出現錯誤。管理表單數據丟失或已被篡改驗證表格

ERROR 「POST /新/ HTTP/1.1」 500 59

HTML

<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功能來發送數據

$("#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); 
    }

我到底做錯了什麼？任何幫助將不勝感激。 Multiple formsets

編輯我沒有改變表單集數。我的CSRF工作正常。此外，我沒有ajax得到同樣的問題。

<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" />

你確定你傳入的csrf標記是正確的嗎？ – Bono

您是否使用javascript來更改formset中窗體的數量？ – schwobaseggl

如果您提交沒有Ajax的表單，它會工作嗎？它看起來好像你的'data'包含csrf標記，但沒有別的。 – Alasdair

如果在發送到瀏覽器後表單數量發生了變化，formset會引發此確切錯誤。該表單使用management_form中名稱form-TOTAL_FORMS的隱藏輸入字段來跟蹤該號碼。從docs：

It is used to keep track of how many form instances are being displayed. If you are adding new forms via JavaScript, you should increment the count fields in this form as well.
