Django：在表单中覆盖clean（）方法 - 提出错误的问题 [英] Django: Overriding the clean() method in forms - question about raising errors

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：
 
 
 
  https://docs.djangoproject.com/en/1.7/ref/forms/validation/#cleaning-and-validating-fields-that-depend-on-each-other  
  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:

https://docs.djangoproject.com/en/1.7/ref/forms/validation/#cleaning-and-validating-fields-that-depend-on-each-other
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
