验证单个字段是没有问题的。self.cleaned_data 显示值!
但是当我想在clean 方法中打印 self.cleaned_data 时,所有值的结果都是 None !这将如何发生?我还尝试使用 Super() 获取数据……但没有运气……有什么想法吗?
def validator_number_or_one_letter(fieldvalue):
if not re.match("^[A-Za-z0-9]*$", fieldvalue) or len(fieldvalue)>1:
raise forms.ValidationError("Error, Error!")
class CodeForm(forms.Form):
letter_one = forms.CharField(widget=forms.TextInput(attrs={'placeholder': '#','requiried':'required','required': 'true','size':'1','class':'first-field' }))
letter_two =forms.CharField(widget=forms.TextInput(attrs={'placeholder': '#','requiried':'required','required': 'true','size':'1' }))
letter_three = forms.CharField(widget=forms.TextInput(attrs={'placeholder': '#', 'requiried':'required','required': 'true','size':'1' }))
letter_four = forms.CharField(widget=forms.TextInput(attrs={'placeholder': '#','requiried':'required','required': 'true','size':'1' }))
letter_five = forms.CharField(widget=forms.TextInput(attrs={'placeholder': '#','requiried':'required','required': 'true','size':'1' }))
def clean(self):
#cleaned_data = super(CodeForm, self).clean() ###this does not work either
#print cleaned_data ###this does not work either
print self.cleaned_data['letter_one']

validator_number_or_one_letter(self.cleaned_data['letter_one'])
