我正在使用django-dynamic-formset将表单动态添加到表单集中。
只要我extra=1在创建表单集时可以正常工作。
不过，我想做的是在用户单击“添加表单”按钮之前不显示任何表单。推荐
的解决方案是使用，但由于某种原因不起作用（不起作用意味着没有记录保存到数据库中）。按照工作代码，不使用empty_form： empty_forms
<div id="coding">
<div id="coding-inner">
<form action="" method="post" accept-charset="utf-8" id="form">
{% csrf_token %}
{{ formset.management_form }}
{% for form in formset %}
<div class="form-container">
<table border="0" cellspacing="5" cellpadding="5">
<tr>
<td><label for="id_form-0-event_date">Event Date:</label></td>
<td>{{ form.event_date}}</td>
</tr>
<tr>
<td><label for="id_form-0-location">Location:</label></td>
<td><div class="location_wrapper">{{ form.location }}</div></td>
</tr>
<tr>
<td><label for="id_form-0-actors">Actors:</label></td>
<td>{{ form.actors }}</td>
</tr>
<tr>
<td><label for="id_form-0-num_participants">Number of Participants:</label></td>
<td>{{ form.num_participants }}</td>
</tr>
<tr>
<td><label for="id_form-0-issue">Issue:</label></td>
<td>{{ form.issue }}</td>
</tr>
<tr>
<td><label for="id_form-0-side">Side:</label></td>
<td>{{ form.side }}</td>
</tr>
<tr>
<td><label for="id_form-0-scope">Scope:</label></td>
<td>{{ form.scope }}</td>
</tr>
<tr>
<td><label for="id_form-0-part_violence">Participant Violence:</label></td>
<td>{{ form.part_violence}}</td>
</tr>
<tr>
<td><label for="id_form-0-sec_engagement">Security Forces Engagment:</label></td>
<td>{{ form.sec_engagement }}</td>
</tr>
</table>
</div>
{% endfor %}
<div id="form-nav">
<div id="save-stay">
<input type="submit" name="coding_form_save" value="Save">
</div>
<div id="save-next">
<input type="submit" name="coding_form_next" value="Save & Next">
</div>
</div>
</form>
</div>
<div id="pagination">
<span class="step-links">
{% if articles.has_previous %}
<a href="?page={{ articles.previous_page_number }}">previous</a>
{% endif %}
<span class="current">
Article {{ articles.number }} of {{ articles.paginator.num_pages }}.
</span>
{% if articles.has_next %}
<a href="?page={{ articles.next_page_number }}">next</a>
{% endif %}
</span>
</div>
</div>
</div>
<script type="text/javascript">
$(function() {
$('.form-container').formset({
prefix: '{{ formset.prefix }}',
addText: 'add Event',
deleteText: 'delete Event'
});
})
</script>
现在使用的代码empty_form不起作用。唯一的其他区别是，对于使用 的代码empty_form，extra将其设置为 0 而不是 1。
<div id="coding">
<div id="coding-inner">
{% with formset.empty_form as form %}
<div id="form-container" style="display:none;">
<table border="0" cellspacing="5" cellpadding="5">
<tr>
<td><label for="id_form-0-event_date">Event Date:</label></td>
<td>{{ form.event_date}}</td>
</tr>
<tr>
<td><label for="id_form-0-location">Location:</label></td>
<td><div class="location_wrapper">{{ form.location }}</div></td>
</tr>
<tr>
<td><label for="id_form-0-actors">Actors:</label></td>
<td>{{ form.actors }}</td>
</tr>
<tr>
<td><label for="id_form-0-num_participants">Number of Participants:</label></td>
<td>{{ form.num_participants }}</td>
</tr>
<tr>
<td><label for="id_form-0-issue">Issue:</label></td>
<td>{{ form.issue }}</td>
</tr>
<tr>
<td><label for="id_form-0-side">Side:</label></td>
<td>{{ form.side }}</td>
</tr>
<tr>
<td><label for="id_form-0-scope">Scope:</label></td>
<td>{{ form.scope }}</td>
</tr>
<tr>
<td><label for="id_form-0-part_violence">Participant Violence:</label></td>
<td>{{ form.part_violence}}</td>
</tr>
<tr>
<td><label for="id_form-0-sec_engagement">Security Forces Engagment:</label></td>
<td>{{ form.sec_engagement }}</td>
</tr>
</table>
</div>

我错过了什么？
