Question

所以这真的很奇怪。当我做clean_email时，我收到一个错误，然后为emailConfirm输出“None”。当我做clean_emailConfirm时，它完美无缺。由于某种原因，我得到了不同的结果，即使我唯一要改变的是函数的名称（clean_email到clean_emailConfirm）。有人有任何想法吗？

class SignUpForm(forms.ModelForm):
    fname = forms.CharField(max_length=256, label="", required=True, widget=forms.TextInput(attrs={'class': 'form-control','placeholder': 'First Name','required':True}))
    lname = forms.CharField(max_length=256, label="", required=True, widget=forms.TextInput(attrs={'class': 'form-control','placeholder': 'Last Name','required':True}))
    email = forms.EmailField(max_length=256, label="", required=True, widget=forms.EmailInput(attrs={'class': 'form-control','placeholder': 'Email','required':True}))
    emailConfirm = forms.EmailField(max_length=256, label="", required=True, widget=forms.EmailInput(attrs={'class': 'form-control','placeholder': 'Email','required':True}))
    password = forms.CharField(max_length=256, label="", required=True, widget=forms.PasswordInput(attrs={'class': 'form-control','placeholder': 'Password','required':True}))
    datetime = forms.DateTimeInput()

    class Meta:
        model=SignUp
        fields=['fname','lname','email','emailConfirm','password']

    # def clean_email(self):    
    #   email=self.cleaned_data.get('email')
    #   emailConfirm=self.cleaned_data.get('emailConfirm')
    #   if email != emailConfirm:
    #       #print(cleaned_data2)
    #       print(email)
    #       print(emailConfirm)
    #       raise forms.ValidationError("Your two emails must be the same!")
    #   else:
    #       return email
    def clean_emailConfirm(self):   
        email=self.cleaned_data.get('email')
        emailConfirm=self.cleaned_data.get('emailConfirm')
        if emailConfirm != email:
            #print(cleaned_data2)
            print(email)
            print(emailConfirm)
            raise forms.ValidationError("Your two emails must be the same!")
        else:
            print(emailConfirm)
            print(email)
            return email

您无法通过clean_foo方法交叉验证字段，因为并非所有字段都是＆＃39;当您在其中一个方法中时，会调用clean_foo个方法，因此可能存在一些尚未填充的表单值。它应该在clean方法中完成。 Django doc非常明确地记录了这一点：

当调用表单的clean（）方法时，所有个体将运行字段清理方法（前两节），所以 self.cleaned_data将填充任何幸存下来的数据远。所以你还需要记住允许的事实您想要验证的字段可能无法在初始阶段幸存个别实地考察。
