    class userInfoForm(forms.ModelForm):
        class Meta:
            model = userInfo
        def __init__(self, *args, **kwargs):        
            super(userInfoForm,self).__init__()

推荐答案

在 __ unicode __ 方法中 userInfo 尝试使用 self.suggestion 但建议未在模型字段中定义。

Inside the__unicode__ method of userInfo, you are trying to use self.suggestion but suggestion is not defined in the model fields.

尝试使用另一个属性：

class userInfo(models.Model):
    # Model fields..
    def __unicode__(self):
        return self.u_name
