我有一个Django 1.8表单,其中包含一个段落标记,可以呈现一些反馈或用户提交的问题。它还包含一个textarea输入'response_text'和一对单选按钮'close_issue'。此响应输入可用于向用户发送可选响应。如果用户提交了一些反馈,管理员应该能够点击“关闭问题”单选按钮并提交表单而不做任何回复。但是,如果textarea输入包含一个问题,那么表单应该呈现错误,告诉管理员他/她无法在不在响应输入中键入答案的情况下提交表单。我遇到的问题是,如果用户提交了一个问题但管理员没有输入响应,我无法获取表单导致模板呈现错误消息。我的视图,模型,表单和模板如下所示。 forms.py显示所有方式(全部注释掉)如果用户提交了一个问题,我试图使响应输入字段成为必需,以便模板显示错误。我还尝试覆盖默认的'clean'方法,如果用户提交了一个问题并且响应输入为空但但也无效,则会引发ValidationError。谁能告诉我我做错了什么?
感谢。

当您在POST上实例化时,您没有将submission
传递给表单,因此永远不会设置所需的属性。

下一个问题是我在init方法中的语句顺序不正确。在尝试引用'response_text'字段之前,我似乎需要执行'super()'。我需要在Django源代码中找到并研究这个方法,以确切了解原因。无论如何,这都有效:
def __init__(self, *args, **kwargs):
if 'submission' in kwargs:
submission = kwargs.pop('submission')
else:
submission = False
super(FeedbackQuestionResponseForm, self).__init__(*args, **kwargs)
if submission:
if submission.submission_type == 'question':
self.fields['response_text'].required = True
else:
self.fields['response_text'].required = False
当实施上述更改时,如果用户提交问题,表单将使response_text字段成为必需,如果管理员在提交表单之前未输入响应,则会显示错误。非常感谢Daniel让我重新走上寻找解决方案的道路。
