如何自动将对象与创建它的用户连接并仅显示特定用户在 django 中创建的那些对象？

Question

我正在 django 中制作房地产应用程序，我遇到的问题是用户可以登录他的帐户并开始创建他的属性，然后他可以查看这些属性，但我得到的是每个用户的属性在页面上，而它应该只是特定用户创建的属性。

这里是属性的models.py，我使用的是django的用户模型

from django.core.urlresolvers import reverse
from django.contrib.auth.models import User

class Property(models.Model):
title = models.CharField(max_length = 210,default = 'None')

STATUS_CHOICES = (
('R','Rent'),
('S','Sale'),
    )

status = models.CharField(max_length = 210,choices =     STATUS_CHOICES,default = 'None')

price = models.IntegerField(default = 'None')

area = models.CharField(max_length = 210,default = 'None')

ROOM_CHOICES = (
('1','1'),
('2','2'),
('3','3'),
('4','4'),
('MORE','More'),
    )

rooms = models.CharField(max_length = 210,choices = ROOM_CHOICES,default = 'None')
BATHROOM_CHOICES = (
('1','1'),
('2','2'),
('3','3'),
('4','4'),
    )
bathroom = models.CharField(max_length = 210,choices = BATHROOM_CHOICES,default = 'None')
address = models.CharField(max_length = 210,default = 'None')
state = models.CharField(max_length = 210,default = 'None')
code = models.CharField(max_length = 210,default = 'None')
images = models.ImageField(upload_to = 'media',default = 'None')
info = models.TextField(max_length = 1000,default = 'None')
parking = models.BooleanField(default = False)
air = models.BooleanField(default = False)
swimming = models.BooleanField(default = False)
laundry = models.BooleanField(default = False)
dealer_name = models.CharField(max_length = 210,default = 'None')
dealer_email = models.EmailField(max_length = 210,default = 'None')
dealer_number = models.CharField(max_length = 210,default = 'Not mentioned')
user = models.ForeignKey(User,related_name = 'user')



def get_absolute_url(self,*args,**kwargs):
    return reverse('profile_details:property', kwargs={'pk':self.pk,})

我还需要一些课程的帮助，这些课程可以帮助我完整而清晰地完成 django，以便我以后可以遇到这些问题。如果你知道，请在 cmets 中写下来。

您有两个选项来获取用户的属性。

使用filter() 方法：

# View to display the user properties
def properties_page(request):
    properties = Property.objects.filter(user=request.user)
    return render(request, 'app/user_properties.html', {'properties': properties})

使用_set.all()

# View to display the user properties
def properties_page(request):
    properties = request.user.property_set.all()
    return render(request, 'app/user_properties.html', {'properties': properties})
