正在触发管理表单集错误
Management Formset error is getting triggered
下面的 HTML 代码返回 ['ManagementForm data is missing or has been tampered with']。这个 HTML 给了我想要的自定义外观,但为什么会这样?我不明白,因为我已经声明了 management_data 标签。
HTML
<form method="POST" enctype="multipart/form-data" action=".">
{{ formset.management_data }}
<!-- Security token -->
{% csrf_token %}
{{ formset.non_form_errors.as_ul }}
<table>
{% for form in formset.forms %}
{% if forloop.first %}
<thead>
<tr>
{% for field in form.visible_fields %}
<th name={{field.label}}>{{ field.label }}</th>
{% endfor %}
</tr>
</thead>
{% endif %}
<tr class="{% cycle row1 row2 %}">
{% for field in form.visible_fields %}
<td name={{field.label}}>
{# Include the hidden fields in the form #}
{% if forloop.first %}
{% for hidden in form.hidden_fields %}
{{ hidden }}
{% endfor %}
{% endif %}
{{ field.errors.as_ul }}
{{ field }}
</td>
{% endfor %}
</tr>
{% endfor %}
</table>
</form>
您需要在模板中包含 {{ formset.management_form }}
而不是 {{ formset.management_data }}
。 Docs
