blu*_*inc 3 python django django-forms django-views
在我看来,我可以访问form['item'].errors它,它给了我类似的东西:
> form.is_valid()
False
>
> e = form['name'].errors
>
> print e
<ul class="errorlist"><li>There already exists an item with this name. Try a different one.</li></ul>
>
> e.as_text()
* name\n * There already exists an item with this name. Try a different one.

但是,如何在There already exists...没有 HTML 标记或*name\n *显示的情况下访问错误消息?

我相信你正在寻找as_data()。
对于整个表格:
print(form.errors.as_data())
{'foo': [ValidationError([u'This is an error.'])], 'bar': [ValidationError([u'This is another error.'])]}

对于一个字段:
for e in form.errors['foo'].as_data():
print e
[u'This field is required.']
