Question

我有一个模板，其中包括一个ModelForm，一个ModelFormSet和一个Submit按钮，该按钮应该提交来自Form和FormSet的所有表单数据。问题是，当我提交数据时，如果数据无效，有时模板将重新加载，并且提交按钮位于表单容器之外，怎么办？ -尽管用户可以编辑表单中的数据以使其有效，但他们不再能够提交表单。此外，提交按钮也不会浮动。我使用ID为“ add_def_report”的按钮将表单动态添加到event_formset中（我向event_formset添加了“ empty_form”并更改了ID）。谢谢您的帮助！

模板：

<form method="post" class="form-horizontal">

{% crispy incident_form %}

<input type="button" id="delete_field_data" class="btn btn-outline-danger" value="Delete Field Incident Data">

<div id="form_set_class">
  {{ incident_formset.management_form }}
  {% for form in incident_formset %}
    {{form.non_field_errors}}
    {{form.errors}}
    {% crispy form %}
  {% endfor %}
</div>

<p>Add a part deficiency report for each component which needs repair or replacement</p>
<input type="button" id="add_def_report" class="btn btn-outline-dark" value="Add Part Deficiency Report">

<div id="empty_form" style="display:none">
  <div id="incident___prefix__">

    <fieldset>
      <legend>Part Deficiency Report</legend>
      {{incident_formset.empty_form}}
      <br>
      <input type="button" id='delete_incident___prefix__' class="btn btn-outline-danger" value="Delete Part Deficiency Report" onclick="delete_def_report()">
    </fieldset>

  </div>
</div>

<input type="submit" class="btn btn-outline-primary custom-submit" value="Submit">
</form>

CSS：

.center-text{
  display: block;
  text-align: center;
}

form{
  display: inline-block;
  margin-right: auto;
  margin-left: auto;
  text-align: left;
}

legend {
  float: left; /*allows for top margin */
  border-bottom: 1px solid black;
  margin-bottom: 20px;
  margin-top: 20px;
}

#form_set_class{
  width: auto;
  text-align: left;
}

#form_set_class *{
  display: block;
}

#add_def_report{
  text-align: left;
}

好的，所以我找到了解决提交按钮混乱行为的方法-我将所有内容都封装在div的form标签内。这显然有效，但是从技术上讲不能回答我的问题，因为它不能解释为什么会发生。但是，我将其发布为答案，以将其与上面的故障排除注释分开。如果找到原因的答案，请在此处添加。

从无效帖子重新加载表单后，为什么我的提交按钮重新放置在Django表单之外？
