如何将 PhoneNumberField 数据保存到数据库？

Question

我的 forms.py 文件

class CreateUserForm(UserCreationForm):
    phone=PhoneNumberField()
    class Meta:
        model = User
        fields = ['username', 'email', 'password1', 'password2', 'phone']
        widgets={
            'username':forms.TextInput(attrs={'placeholder':"Username"}),
            'email':forms.TextInput(attrs={'placeholder':"Email Address"}),
            'password1': forms.PasswordInput(attrs={'placeholder': 'Your Password'}),
            'password2': forms.PasswordInput(attrs={'placeholder': 'Confirm Password'}),
            'phone':PhoneNumberField(),
        }

我的 models.py 文件

class CustomerReg(models.Model):
    user=models.OneToOneField(User, null=True, blank=True, on_delete=models.CASCADE)
    name=models.CharField(max_length=200, null=True)
    email=models.EmailField(max_length=254)

def create_profile(sender, **kwargs):
    if kwargs['created']:
        user_profile=CustomerReg.objects.create(user=kwargs['instance'])

post_save.connect(create_profile, sender=User)

我的views.py文件

def registerPage(request):
    if request.user.is_authenticated:
        return redirect('form')
    else:
        form=CreateUserForm()

        if request.method == 'POST':
            form = CreateUserForm(request.POST)
            if(form.is_valid()):
                form.save()
                user=form.cleaned_data.get['username']
                user=User.objects.get(username=user)
                phone=form.cleaned_data.get['phone']
                user.phone_number=phone
                user.save()
                return redirect('login')

        context = {'form': form}
        return render(request, 'customer/register.html', context)

点击注册页面时会显示错误

AttributeError at /register/
'str' object has no attribute 'User'

那么我有没有办法保存表单中的数据，因此我必须创建新的自定义用户模型才能在注册页面上保存用户的电话号码？

我的管理员.py

from django.contrib import admin
from .models import *
from django.contrib.auth.admin import UserAdmin as BaseUserAdmin
from .forms import UserChangeForm,UserCreationForm
# Register your models here.

admin.site.register(Customer)

class UserAdmin(BaseUserAdmin):
    form = UserChangeForm
    add_form = UserCreationForm
    list_display = ('email', 'phone')

admin.site.register(User, UserAdmin)

Answer 1

如果您的模型创建正确，那么您所犯的错误是您的变量 user 不是 User 对象。该错误通知您user 变量表示一个字符串（来自表单的输入），它没有User 作为其属性。在这种情况下，您可能需要执行类似的操作

user = User.objects.get(username=user)

为了将User 对象分配给变量user。

既然user 是一个User 对象，那么，你可以这样做

user.phone_number = phone
user.save()

Answer 2

请试试这个：

def registerPage(request):
    if request.user.is_authenticated:
        return redirect('form')
    else:
        form=CreateUserForm()

        if request.method == 'POST':
            form = CreateUserForm(request.POST)
            if form.is_valid():
                form.save()
                username=form.cleaned_data['username']
                user=User.objects.get(username=username)
                phone=form.cleaned_data['phone']
                user.phone=phone
                user.save()
                return redirect('login')

        context = {'form': form}
        return render(request, 'customer/register.html', context)

那么您是否为管理员显示电话字段，

admin.py

from .forms import UserChangeForm,UserCreationForm
from django.contrib import admin
from django.contrib.auth.models import User
from django.contrib.auth.admin import UserAdmin as BaseUserAdmin
class UserAdmin(BaseUserAdmin):
    form = UserChangeForm
    add_form = UserCreationForm
    list_display = ('email', 'phone') # You can add field to display field here..
    list_filter = ('name')
    fieldsets = (
       (None, {'fields': ('email')}),
       ('Personal info', {'fields': ('name','phone')}),
       ('Permissions', {'fields': ('name',)}),
    )
    add_fieldsets = (
       (None, {
          'classes': ('wide',),
          'fields': ('name' ,'user','email','email', 'phone')
       }),
    )
    search_fields = ('email',)
    ordering = ('email',)
    filter_horizontal = ()
admin.site.register(User, UserAdmin)
