如何使用Django表单从外键呈现一种特定数据

如何解决如何使用Django表单从外键呈现一种特定数据

我想要的

我正在尝试构建一个应用程序，以便用户可以从商店预订一些产品。我的预订模型中有一个名为客户的外键。我只想在该字段中呈现当前登录的客户。

问题

问题是当我尝试使客户通过下拉菜单抓住所有现有客户时。 我的问题是如何从客户外键中过滤当前登录的客户。我附上了截图 Untitled.png

此处 views.py

@login_required(login_url='adminlogin')
@allowed_users(allowed_roles=['USER'])
def User_Booking(request):
    #booking = Booking.object.get(id=pk)
    bookingForm = forms.BookingForm()
    if request.method == 'POST':
        bookingForm = forms.BookingForm(request.POST)
        if bookingForm.is_valid():
            booking = bookingForm.save(commit=False)
            booking.save()
return render(request,'user_booking.html',{'bookingForm':bookingForm})

此处 models.py

class Customer(models.Model):
user = models.OneToOneField(User,on_delete=models.CASCADE)
profile_image = models.ImageField(upload_to='profile_pic/CustomerProfilePic/',null=True,blank=True)
address = models.CharField(max_length=40,null=True)
mobile = models.CharField(max_length=20,null=True)
date_created = models.DateTimeField(auto_now_add=True,null=True)
status=models.BooleanField(default=False)

@property
def get_name(self):
    return self.user.first_name+" "+self.user.last_name

@property
def get_id(self):
    return self.user.id

def __str__(self):
    return "{} {}".format(self.user.first_name,self.user.last_name)

class Booking(models.Model):
    customer = models.ForeignKey(Customer,on_delete=models.SET_NULL)
    Package = models.ForeignKey(Package,on_delete=models.SET_NULL)
    address = models.CharField(max_length=40,null=True)
    mobile = models.CharField(max_length=20,null=True)
    date_created = models.DateTimeField(auto_now_add=True,null=True)
    status=models.BooleanField(default=False)

    def __str__(self):
        return self.customer.get_name

此处 user_booking.html

           <form action="" method="POST" enctype="multipart/form-data">
                {% csrf_token %}
                <div class="mb-3">
