模板

#all errors are here
{% for dict in form_errors %}
    {{ dict }}
{% endfor %}

#all forms are here,i want to pair the errors for each form
<form method="post" action="/test/{{ author.id }}/books/">
    {% csrf_token %}
        <table>
        {{ formset }}
        </table>
    <input type="submit" value="Submit"/>
    </form>

UPDATED TEMPLATE：不显示错误

<form method="post" action="/test/{{ author.id }}/books/">
    {% formset.management_form %}
    {% csrf_token %}
    <table>
        {% for x in formset %}
        {{x.errors }}
        {{ x }}
        {% endfor %}
    </table>
<input type="submit" value="Submit"/>

authors_books_edits.html

<form method="post" action="/test/{{ author.id }}/books/">
    {% csrf_token %}
    {{ formset.management_form }}
    {% for form in formset.forms %}
        {{ form.non_field_errors }}
        {{ form.errors }}

您可以制作另一个临时应用来测试它.

它看起来像这样：http://imageshack.us/photo/my-images/824/screenshotat20120227190.png/

==结束编辑

您可以这样迭代表单：

{% for form in formset.forms %}
   {{ form }}
{% endfor %}

在这种情况下,请参阅Django使用模板文档显示表单：https://docs.djangoproject.com/en/dev/topics/forms/#displaying-a-form-using-a-template

然后,更有趣的是,自定义表单模板(请参阅form.non_field_errors)：
https://docs.djangoproject.com/en/dev/topics/forms/#customizing-the-form-template
