本文介绍了Django:在表单中覆盖clean()方法 - 提出错误的问题的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
if self.cleaned_data ['type']。 organ_by!= self.cleaned_data ['organized_by']:
raise forms.ValidationError('类型和组织不匹配')
如果self.cleaned_data ['start']> self.cleaned_data ['end']:
raise forms.ValidationError('开始日期不能晚于结束日期')
但是这意味着表单一次只能引发其中一个错误。有没有办法提出这两个错误?
编辑#1 :
上述任何解决方案很棒,但是会喜欢在一个场景中也可以使用的东西:
if self.cleaned_data ['type']。organized_by != self.cleaned_data ['organized_by']:
raise forms.ValidationError('类型和组织不匹配')
如果self.cleaned_data ['start']> self.cleaned_data ['end']:
raise forms.ValidationError('开始日期不能晚于结束日期')
super(FooAddForm,self).clean()
其中FooAddForm是一个ModelForm,具有唯一的约束,也可能会导致错误。如果有人知道这样的东西,那将是很棒的... 解决方案从文档:
from django.forms.util import ErrorList
def clean(self):
如果self.cleaned_data ['type']。organized_by!= self.cleaned_data ['organized_by']:
msg ='类型和组织不匹配'
self。 _errors ['type'] = ErrorList([msg])
del self.cleaned_data ['type']
如果self.cleaned_data ['start']> self.cleaned_data ['end']:
msg ='开始日期不能晚于结束日期'
self._errors ['start'] = ErrorList([msg])
del self.cleaned_data ['start']
return self.cleaned_data
I've been doing things like this in the clean method:
if self.cleaned_data['type'].organized_by != self.cleaned_data['organized_by']:
raise forms.ValidationError('The type and organization do not match.')
if self.cleaned_data['start'] > self.cleaned_data['end']:
raise forms.ValidationError('The start date cannot be later than the end date.')
But then that means that the form can only raise one of these errors at a time. Is there a way for the form to raise both of these errors?
EDIT #1:Any solutions for the above are great, but would love something that would also work in a scenario like:
if self.cleaned_data['type'].organized_by != self.cleaned_data['organized_by']:
raise forms.ValidationError('The type and organization do not match.')
if self.cleaned_data['start'] > self.cleaned_data['end']:
raise forms.ValidationError('The start date cannot be later than the end date.')
super(FooAddForm, self).clean()
Where FooAddForm is a ModelForm and has unique constraints that might also cause errors. If anyone knows of something like that, that would be great...
解决方案 From the docs:
from django.forms.util import ErrorList
def clean(self):
if self.cleaned_data['type'].organized_by != self.cleaned_data['organized_by']:
msg = 'The type and organization do not match.'
self._errors['type'] = ErrorList([msg])
del self.cleaned_data['type']
if self.cleaned_data['start'] > self.cleaned_data['end']:
msg = 'The start date cannot be later than the end date.'
self._errors['start'] = ErrorList([msg])
del self.cleaned_data['start']
return self.cleaned_data
