我是python的新手，我正在尝试进行从用户创建模型扩展的用户注册，我使用所需的字段创建了配置文件模型，并在保存用户时保存了带有信号的配置文件对象，配置文件创建成功并与用户链接，但配置文件数据未保存(在此示例中： 职位、公司、电话(为空
在 model.py
class profile (models.Model):
user = models.OneToOneField(User, on_delete = models.CASCADE)
company = models.CharField(max_length=100)
jobTitle = models.CharField(max_length = 100,default ='')
phonenumber = PhoneNumberField(null=False, blank=False, unique=True, help_text='Contact phone number', default ='')
@receiver(post_save, sender = User)
def create_user_profile( sender, instance, created, **kwargs):
if created:
profile.objects.create(user = instance)
instance.profile.save()
@receiver(post_save, sender=User)
def save_profile(sender, instance, **kwargs):
instance.profile.save()
在 forms.py
class UserRegisterForm(UserCreationForm):
email = forms.EmailField(required= True)
company = forms.CharField(required = True)
phonenumber = PhoneNumberField(widget=forms.TextInput(attrs={'placeholder': ('Phone')}), label=("Phone number"), required=True)
first_name = forms.CharField(required = True)
jobTitle = forms.CharField(required = True)
class Meta:
model = User
fields = [
'username',
'first_name',
'last_name',
'email',
'password1',
'password2',
'company',
'jobTitle'
]
def save(self, commit=True):
user = super(UserRegisterForm, self).save(commit=False)
user.first_name = self.cleaned_data['first_name']
user.last_name = self.cleaned_data['last_name']
user.email = self.cleaned_data['email']
if commit:
user.save()
return user
在 views.py
#User register
def signup(request):
if request.method == 'POST':
form = UserRegisterForm(request.POST)
if form.is_valid():
user = form.save()
UserProfile = user.profile
username = form.cleaned_data.get('username')
company = form.cleaned_data.get('company')
jobTitle = form.cleaned_data.get('jobTitle')
phonenumber = form.cleaned_data.get('phonenumber')
UserProfile.save()
messages.success(request, f'Account is created for {username}!')
return redirect('login')
else:
form = UserRegisterForm()
return render(request, 'users/signup.html', {'form': form})
那么，您能帮助我了解导致此问题的原因吗？我希望在注册到配置文件模型时保存插入的值。
谢谢
删除第二个@receiver(post_save, sender=User)，这是无用的(它总是在#1配置文件中完成(。
当你做user = form.save()时，信号被抬起，创建一个空profile。
因此，就在user = form.save()之后，获取通过信号创建的配置文件，例如：
profile = Profile.objects.get(user=user)
username = form.cleaned_data.get('username')
company = form.cleaned_data.get('company')
jobTitle = form.cleaned_data.get('jobTitle')
phonenumber = form.cleaned_data.get('phonenumber')
profile.save()
我的建议是：阅读 Python 的 PEP8：类总是"UpCase"，变量总是lower_case。
你还需要在应用程序中导入信号，让 django 知道你的实现。
您可以通过以下方式实现它：
from django.apps import AppConfig
class UsersConfig(AppConfig):
name = 'users'
def ready(self):
import users.signals
