在表单中创建 mixin 以检查密码

Question

我有一些 Patient、Doctors 等模型，然后我使用它们创建基于 ModelForm 的表单，其中包含一些附加字段：

class CreateClinicForm(forms.ModelForm):
    email = forms.EmailField(required=True)
    name = forms.CharField(max_length=200, required=True)
    specialties = forms.CharField(max_length=100, required=True)
    phone = forms.IntegerField(required=True)

    class Meta:
        model = Clinic
        fields = ('name', 'specialties')

而且我在这些表单中进行了密码检查，所以使用 mixin 会很好。我试过创建这个，但是没有用。

class PasswordMatchMixin(object):
    password = forms.CharField(max_length=32, required=True)
    password_confirm = forms.CharField(max_length=32, required=True)

def clean_password_confirm(self):
    password = self.cleaned_data.get('password')
    password_confirm = self.cleaned_data.get('password_confirm')
    if password and password != password_confirm:
        raise ValidationError(_("Passwords don't match"))
    return self.password_confirm

当然，之后我像这样将它添加到我的表格中：

class CreateDoctorForm(PasswordMatchMixin, forms.ModelForm) : ...

有什么想法或想法？

如果您是 cleaning fields that rely on each other，您应该覆盖 clean 而不是 clean_password。

class PasswordMatchMixin(object):
    password = forms.CharField(max_length=32, required=True)
    password_confirm = forms.CharField(max_length=32, required=True)

    def clean(self):
        cleaned_data = super(PasswordMatchMixin, self).clean()
        password = cleaned_data.get('password')
        password_confirm = cleaned_data.get('password_confirm')
        if password and password != password_confirm:
            raise ValidationError(_("Passwords don't match"))
        return cleaned_data

如果您在表单中覆盖 clean，请记住调用 super() 以便调用 PasswordMatchMixin.clean 方法。
