问题描述
我正在使用 python 3.6 和 Django V 2.2 创建一个 Django 项目。现在在 Django 管理面板（超级用户）中无法将用户类型转换为人员。它也无法编辑某些用户字段。我已经在我的本地主机和 Postgresql DB（PG 管理员）Apache2 服务器上尝试过 DB.sqlite。 请为我的问题提供任何解决方案。我已经在下面描述了所有相关代码。 还可以找到我的问题的附件。 Django Admin 显示成功消息。但行动无果 (https://i.ibb.co/tDstxff/django-adminerror.png)Error after change user to staff
我的项目文件是：models.py

class UsersAdmin(BaseUserAdmin):

admin.site.site_header = 'Django- administration'
admin.site.register(CustomUser,UsersAdmin)
admin.site.register(Tree)
admin.site.register(Transaction)
admin.site.register(DefaultValues)
admin.site.register(ContactUS)
admin.site.register(AdminProfit)
admin.site.register(ErrorLog)
我还粘贴了 Users/Views.py 用于注册视图
# customer registration page
class SignUp(SuccessMessageMixin,generic.CreateView):
model = CustomUser
form_class = CustomUserCreationForm
template_name = "proApp/signup.html"
success_url = reverse_lazy('proApp:login')
success_message = "Successfully registered"
def form_valid(self,request,form):
form.instance.usertype = "2"
result = super().form_valid(form)
return result
最后这是我在 Users/forms.py
中的用户更改表单class CustomUserChangeForm(UserChangeForm):
class Meta:
model = get_user_model()
fields = (
'first_name','last_name','email','mobile','user_doc')
widgets = {
'first_name': forms.TextInput(attrs={'class': 'form-control','placeholder': 'First Name','required': 'required'}),'last_name': forms.TextInput(attrs={'class': 'form-control','placeholder': 'Last Name','mobile': forms.TextInput(attrs={'class': 'form-control','placeholder': 'Mobile','email': forms.TextInput(attrs={'class': 'form-control','placeholder': 'Email','address': forms.TextInput(attrs={'class': 'form-control','placeholder': 'Address'}),'zipCode': forms.TextInput(attrs={'class': 'form-control','placeholder': 'Zip Code'}),'country': forms.TextInput(attrs={'class': 'form-control','placeholder': 'Country'}),'bank_ac_no': forms.TextInput(attrs={'class': 'form-control','placeholder': 'Account Number','bank_ifsc': forms.TextInput(attrs={'class': 'form-control','placeholder': 'IFSC','bank_proof': forms.FileInput(attrs={'class': 'form-control-file','idproof_no': forms.TextInput(attrs={'class': 'form-control','placeholder': 'ID Proof Number','id_proof': forms.FileInput(attrs={'class': 'form-control-file',}),'user_doc': forms.FileInput(attrs={'class': 'form-control-file',}
解决方法
试试这个：
您可以覆盖 pre_save 模型的 save() 方法，而不是通过 CustomUser 信号更改值。
class CustomUser(AbstractUser):
sponsorId = models.CharField(max_length=256,null=True,blank=True)
mobile = models.CharField(max_length=15,blank=True)
.......
def save(self,*args,**kwargs):
if self.userId is not None:
self.username = self.userId
self.usertype = 2
self.is_staff = False
else:
self.userId = self.username
self.name = self.username
self.usertype = 1
self.is_staff = True
super(CustomUser,self).save(*args,**kwargs)
class meta:
db_table = "Custom User"
