Question

我有一个包含大量表单的模板，所有表单都包含在一个表单元素中。我有MultiForm，它由4个常规表单和两个表单集组成。已重写表单集以使用自定义formset类。我在模板中呈现管理表单，并可以在帖子中看到相关信息。

对于表单集，我初始化页面时只显示一个表单。

当我尝试提交组合表单时，我收到以下错误：

ManagementForm data is missing or has been tampered with

我到处寻找答案，并在堆栈溢出时阅读了大约15个相同错误的帖子，但没有一个解决方案似乎有帮助。

错误页面突出显示以下行：

{{ beneficiaries.management_form }}

模板：

<form class='pension_form' id='implementation_form' action="{% url "confirmation_form" %}" method="post">
 {% csrf_token %}

<ul>
{{ the_form.user_info.as_ul }}  
 </ul>
<ul>
{{ the_form.spouse_info.as_ul }}  
</ul>

 <div class='formset_container'> {{ children.management_form }}
 {% for form in children %}
    <div class='formset'><ul>{{ form.as_ul }}  </ul><a class="glyphicon glyphicon-plus"></a></div>
{% endfor %}
</div>
  <ul>
{{ the_form.employer_info.as_ul }}  
</ul>
  <ul>
<li>{{ the_form.beneficiary_general.WHO_BENEFITS }}</li>
</ul>
<div id='beneficiary_info_container' style='display:none;'>
<div class='formset_container'>
 {{ beneficiaries.management_form }}
{% for form in beneficiaries %}
<div class='formset' >
<ul>{{ form.as_ul }}</ul><a class="glyphicon glyphicon-plus"></a></div>
    {% endfor %}
</div>
<ul><li id='inheritance_order'>
{{ the_form.beneficiary_general.BENEFICIARIES_DIE.label_tag }}
{{ the_form.beneficiary_general.BENEFICIARIES_DIE }}
</li>
</ul>
</div>

<button class='btn btn-default main-btn'>{% trans "_Continue" %}
</form>

如果有人遇到类似的问题：

问题是如果选中了某个复选框，我只显示了表单集，并且管理表单位于隐藏区域。我将它移出了隐藏的div，它完美地工作了。
