我的 views.py 中的这一行代码导致了该问题：
user_checkout = UserCheckout.objects.get(id=user_check_id)
我的 views.py 中有一个名为 OrderList 的基于类的视图。
基本上，我希望登录时模板中返回的列表（订单列表）特定于每个用户
这是我的 views.py
from django.contrib import messages
from django.http import Http404
from django.shortcuts import render, redirect
from django.views.generic.edit import CreateView, FormView
from django.views.generic.detail import DetailView
from django.views.generic.list import ListView
from .forms import AddressForm, UserAddressForm
from .mixins import CartOrderMixin, LoginRequiredMixin
from .models import UserAddress, UserCheckout, Order
class OrderList(LoginRequiredMixin, ListView):
queryset = Order.objects.all()
def get_queryset(self):
user_check_id = self.request.user.id
user_checkout = UserCheckout.objects.get(id=user_check_id)
return super(OrderList, self).get_queryset().filter(user=user_checkout)
class OrderDetail(DetailView):
model = Order
def dispatch(self, request, *args, **kwargs):
try:
user_check_id = self.request.session.get("user_checkout_id")
user_checkout = UserCheckout.objects.get(id=user_check_id)
except UserCheckout.DoesNotExist:
user_checkout = UserCheckout.objects.get(user=request.user)
except:
user_checkout = None
obj = self.get_object()
if obj.user == user_checkout and user_checkout is not None:
return super(OrderDetail, self).dispatch(request, *args, **kwargs)
else:
raise Http404
这是 models.py
from decimal import Decimal
from django.conf import settings
from django.core.urlresolvers import reverse
from django.db import models
from django.db.models.signals import pre_save, post_save
from cart.models import Cart
class UserCheckout(models.Model):
user = models.OneToOneField(settings.AUTH_USER_MODEL, null=True, blank=True) #not required
email = models.EmailField(unique=True)
braintree_id = models.CharField(max_length=120, null=True, blank=True)
def __str__(self): #def __str__(self):
return self.email
@property
def get_braintree_id(self,):
instance = self
if not instance.braintree_id:
result = braintree.Customer.create({
"email": instance.email,
})
if result.is_success:
instance.braintree_id = result.customer.id
instance.save()
return instance.braintree_id
def get_client_token(self):
customer_id = self.get_braintree_id
if customer_id:
client_token = braintree.ClientToken.generate({
"customer_id": customer_id
})
return client_token
return None
class Order(models.Model):
status = models.CharField(max_length=120, choices=ORDER_STATUS_CHOICES, default='created')
cart = models.ForeignKey(Cart, on_delete=models.CASCADE, null=True)
user = models.ForeignKey(UserCheckout, null=True)
billing_address = models.ForeignKey(UserAddress, related_name='billing_address', null=True)
shipping_address = models.ForeignKey(UserAddress, related_name='shipping_address', null=True)
shipping_total_price = models.DecimalField(max_digits=50, decimal_places=2, default=5.99)
order_total = models.DecimalField(max_digits=50, decimal_places=2, null=True )
order_id = models.CharField(max_length=20, null=True, blank=True)
def __str__(self):
return str(self.cart.id)
class Meta:
ordering = ['-id']
def get_absolute_url(self):
return reverse("order_detail", kwargs={"pk": self.pk})
def mark_completed(self, order_id=None):
self.status = "paid"
if order_id and not self.order_id:
self.order_id = order_id
self.save()
这是模板 order_list.html
{% if object_list|length <= 0 %}
<div class='col-sm-6 col-sm-offset-3 text-center'>
<p class='lead'>
You do not currently have orders.
</p>
</div>
{% else %}
<div class='col-sm-6 col-sm-offset-3'>
<h1>Your Orders</h1>
<table class='table'>
{% for object in object_list %}
<tr>
<td>
<a href='{{ object.get_absolute_url }}'>View #{% if object.order_id %}{{ object.order_id }}{% else %}{{ object.id }}{% endif %}</a>
</td>
<td>
Item Count: {{ object.cart.items.count }}
</td>
</tr>
{% endfor %}
</table>
</div>
{% endif %}
这是订购页面
的主要网址（即项目网址） urls.pyurlpatterns = [
url(r'^orders/$', OrderList.as_view(), name='orders'),
url(r'^orders/(?P<pk>\d+)/$', OrderDetail.as_view(), name='order_detail'),
]
请我为您提供更多您需要的详细信息。 问题出在 def get_queryset（self）：函数上。我需要能够对其进行自定义，使其仅基于当前登录用户的退货清单。 但是我可以访问每个单独的订单（即，通过键入管理员已知的URL来查看detailview。）
