获取 Django 表单中的错误列表

问题描述

我正在尝试在 Django 中创建一个表单.这一切都有效，但我希望所有错误都位于表单的顶部，而不是在每个有错误的字段旁边.我尝试遍历 form.errors，但它只显示有错误的字段的名称，而不是诸如需要名称"之类的错误消息.

I'm trying to create a form in Django. That works and all, but I want all the errors to be at the top of the form, not next to each field that has the error. I tried looping over form.errors, but it only showed the name of the field that had an error, not an error message such as "Name is required."

这几乎是我希望能够在表单顶部使用的内容:

This is pretty much what I'd like to be able to use at the top of the form:

{% if form.??? %}
    <ul class="errorlist">
    {% for error in form.??? %}
        <li>{{ error }}</li>
    {% endfor %}
    </ul>
{% endif %}

??? 有什么用?这不是错误；只输出字段的名称.

What would I use for ??? there? It's not errors; that just outputs the names of the fields.

推荐答案

form.errors 是一本字典.当你做 {% for error in form.errors %} 错误对应的键.

form.errors is a dictionary. When you do {% for error in form.errors %} error corresponds to the key.

不如试试

{% for field, errors in form.errors.items %}
    {% for error in errors %}
...

等
