class UserProfileForm(forms.ModelForm):
    sex = forms.CharField(max_length = 20,label="I am :",widget=forms.Select(choices=SEX_CHOICES,attrs = {'class':''}),required = False)
    first_name = forms.CharField(max_length = 50,widget = forms.TextInput(attrs={'placeholder':'Please enter your real name.','class':''}),required = False)
    last_name = forms.CharField(max_length = 50,widget = forms.TextInput(attrs={'placeholder':'Enter last name.','class':''}),required = False)

        self.instance.save()
        return self.instance

    class Meta:
        model = User
        fields = ('first_name','last_name','phone','sex','profession','location')
        #exclude = ('email')

疑问

一切正常，但我无法将信息保存到用户个人资料中，当我使用self.instance.get_profile().phone = self.cleaned_data.get('#some_field')时，因为当我检索的数据没有以m格式显示时，请帮助，提前谢谢

Answer 1

如果我理解得很好，那么您从表单中获取数据并且无法将其保存到用户配置文件中。要解决此问题，您还需要保存用户配置文件：

def save(self,*args,**kw):
    self.instance.first_name = self.cleaned_data.get("first_name")
    self.instance.last_name = self.cleaned_data.get("last_name")
    profile = self.instance.get_profile()
    profile.sex = self.cleaned_data.get("sex")
    profile.location = self.cleaned_data.get("location")
    profile.profession = self.cleaned_data.get("profession")
    profile.phone = self.cleaned_data.get("phone")
    profile.save()
    self.instance.save()
    return self.instance

获取字段时不应使用#。这样做：

self.cleaned_data.get('some_field')
