django 2.0

我有一个django模型,有不同的slug字段:

from django.core.validators import validate_slug

class MyModel(models.Model):
     # with slug field
     slug_field = models.SlugField(max_length=200)

     # or charfield with slug validator (should be exactly the same)
     char_field = models.CharField(max_length=200, validators=[validate_slug])

我的第一个问题,在我的形式,我有一个干净的方法,来验证多个字段的值,而不是单独的.理论上应该在clean_fields方法之后调用此方法,但即使clean_fields引发错误也会调用它.

我的forms.py:

class MyForm(forms.ModelForm):
    class Meta:
        model = MyModel
        fields = '__all__'

    def clean(self):
        cleaned_data = super().clean()
        print(cleaned_data.get('slug_field'))  # > None
        print(cleaned_data.get('char_field'))  # > ééé; uncleaned data
        print(self.errors)  # only from slug_field
        return cleaned_data

使用SlugField时,slug_field未设置cleaned_data,当它无效时,以及在引发错误并由表单返回给用户之后.(我不明白为什么clean()甚至达成,因为clean_fields()之前提出过错误)

问题是,使用CharField …
