在视图*问表单字段“错误”

I want to know in my view, if a certain field raised an error, that way I can send some values to the template (index of current tab (using a javascript tab widget)). Is it possible?

我想在我的视图中知道，如果某个字段引发了错误，那么我可以向模板发送一些值（当前选项卡的索引（使用javascript选项卡小部件））。可能吗？

Thanks in advance.

提前致谢。

You can definitely access your form errors in your view. Each bound Form instance has an errors attribute that gives you a dictionary mapping field name to error-message lists:

您绝对可以在视图中访问表单错误。每个绑定的Form实例都有一个errors属性，该属性为您提供字典映射字段名称到错误消息列表：

>>> f = ContactForm({'subject': 'Hello', 'message':''})
>>> f.errors
{'message':[u'This field is required.']}

You can access individual fields as follows:

您可以按如下方式访问各个字段：

>>> if f['subject'].errors:
        values = [Add values to send to template]
