Question

django的新手，到目前为止爱它。我有一个django管理员，架构设计问题。我有一个拥有客户，产品和订单表的应用程序。客户有一个产品订单，由admin预先构建，并保存在CustomerProduct表中。当客户登录时，他们只能查看他们的订单，更新数量，以及它。他们无法访问产品表或其他客户订单。我现在卡住的三个部分，

订单表应与customer_products表具有多对多关系。
订单历史记录需要以某种方式保存在单独的表中，因此如果用户的订单更改，我们仍会记录其过去的订单。我需要为用户构建一个只显示其订单的视图。 /管理/ onlineordering / ordersheet。
如何设置此网址并限制对经过身份验证的用户的访问权限。用户A只能看到用户A的CustomerProduct（订单）

以下是apps models.py和admin.py

onlineordering / models.py

from django.conf import settings
from django.db import models
from datetime import datetime

class Customer(models.Model):
    customer = models.ForeignKey(settings.AUTH_USER_MODEL, limit_choices_to={'groups__name': "customers"})
    customer_product = models.ManyToManyField('Product', through='CustomerProduct')
    company_name = models.CharField(max_length=255)
    address1 = models.CharField(max_length=255)
    address2 = models.CharField(max_length=255)
    city = models.CharField(max_length=255)
    state = models.CharField(max_length=255)
    zip_code = models.CharField(max_length=255)
    def __unicode__(self):
        return self.company_name

class CustomerProduct(models.Model):
    customer = models.ForeignKey('Customer')
    product = models.ForeignKey('Product')

class Product(models.Model):
    item = models.CharField(max_length=255)
    description = models.CharField(max_length=255)
    def __unicode__(self):
        return self.description

class Order(models.Model):
    customer_product_order = models.ManyToManyField('CustomerProduct', through='CustomerProductOrder')
    purchase_order_number = models.CharField(max_length=10)
    person_placing_order = models.CharField(max_length=255)
    requested_delivery_date = models.DateField(blank=True, null=True)

class CustomerProductOrder(models.Model):
    order = models.ForeignKey('Order')
    customer_product = models.ForeignKey('CustomerProduct')
    quantity = models.IntegerField(default=0)

onlineordering / admin.py

from django.contrib import admin
from django.contrib.auth.admin import UserAdmin

from .models import Order,Customer,Product

UserAdmin.add_fieldsets = (
    (None, {
        'classes': ('wide',),
        'fields': ('username', 'password1', 'password2', 'first_name', 'last_name', 'groups')}
    ),
)

class CustomerProductInline(admin.StackedInline):
    model = Customer.customer_product.through
    extra = 0

class ProductAdmin(admin.ModelAdmin):
    inlines = [
        CustomerProductInline,
    ]

class CustomerAdmin(admin.ModelAdmin):
    inlines = [
        CustomerProductInline,
    ]
    exclude = ('customer_product',)

admin.site.register(Order)
admin.site.register(Customer,CustomerAdmin)
admin.site.register(Product)

更新

/onlineordering/views.py

from django.http import HttpResponse


def ordersheet(request):
    return HttpResponse("Hello, world.")

/urls.py

from django.conf.urls import include, url
from django.contrib import admin

    urlpatterns = [
        url(r'^admin/', include(admin.site.urls)),
        url(r'^admin/onlineordering/ordersheet', include(admin.site.urls)),
    ]
