一、提交订单模块
1.在urls.py配置文件中定义路由
from django.conf.urls import url, include
from order import views
urlpatterns = [
# 结算订单页面
url(r'^place_order/', views.place_order, name='place_order'),
# 下单
url(r'^make_order/', views.make_order, name='make_order'),
]
2.生成随机订单号
import random
import time
# 生成订单交易号
def get_order_sn():
s = '1234567890qwertyuiopasdfghjklzxcvbnmQWERTYUIOPASDFGHJKLZXCVBNM'
order_sn = ''
for i in range(3):
order_sn += random.choice(s)
order_sn += str(time.time())
return order_sn
3.提交订单功能
from django.http import JsonResponse
from django.shortcuts import render
from carts.models import ShoppingCart
from order.models import OrderInfo, OrderGoods
from user.models import UserAddress
from utils.function import get_order_sn
def place_order(request):
if request.method == 'GET':
user_id = request.session.get('user_id')
shop_carts = ShoppingCart.objects.filter(user_id=user_id, is_select=1)
user_address = UserAddress.objects.filter(user_id=user_id)
# 给购物车中的对象绑定一个新增的属性，其值为小计价格
all_total = 0
for carts in shop_carts:
carts.price = carts.nums * carts.goods.shop_price
all_total += carts.price
# 结算商品个数，总价
carts_count = len(shop_carts)
return render(request, 'place_order.html', {'shop_carts': shop_carts, 'carts_count': carts_count,
'all_total': all_total, 'user_address': user_address})
def make_order(request):
if request.method == 'POST':
user_id = request.session.get('user_id')
# 取购物车中勾选的商品
shop_carts = ShoppingCart.objects.filter(user_id=user_id, is_select=1)
# 计算下单的总价
order_mount = 0
for carts in shop_carts:
order_mount += carts.nums * carts.goods.shop_price
# 生成订单交易号
order_sn = get_order_sn()
# 1.创建订单
address_id = int(request.POST.get('address_id'))
user_address = UserAddress.objects.filter(pk=address_id).first()
order = OrderInfo.objects.create(user_id=user_id, order_sn=order_sn, order_mount=order_mount,
address=user_address.address, signer_name=user_address.signer_name,
signer_mobile=user_address.signer_mobile)
# 2.创建订单详情
for carts in shop_carts:
OrderGoods.objects.create(order=order, goods=carts.goods, goods_nums=carts.nums)
# 3.删除购物车中的商品
shop_carts.delete()
request.session.pop('goods')
return JsonResponse({'code': 200, 'msg': '请求成功'})

page_num = request.GET.get('page', 1)
order_info = OrderInfo.objects.filter(user_id=user_id)
paginator = Paginator(order_info, 5)
page = paginator.page(page_num)
return render(request, 'user_center_order.html', {'page': page})

]
2.定义收货地址验证form表单
from django import forms
from user.models import User
class UserRegisterForm(forms.Form):
user_name = forms.CharField(max_length=20, min_length=5, required=True,
error_messages={
'required': '用户名必填',
'max_length': '用户名不能超过20位字符',
'min_length': '用户名不能少于5位字符',
})
pwd = forms.CharField(max_length=20, min_length=8, required=True,
error_messages={
'required': '密码必填',
'max_length': '密码不能超过20位字符',
'min_length': '密码不能少于8位字符'
})
cpwd = forms.CharField(max_length=20, min_length=8, required=True,
error_messages={
'required': '确认密码必填',
'max_length': '密码不能超过20位字符',
'min_length': '密码不能少于8位字符'
})
email = forms.CharField(required=True,
error_messages={
'required': '邮箱必填'
})
# 验证时，会自动调用
def clean(self):
# 校验用户名是否已存在于数据库
user =User.objects.filter(username=self.cleaned_data.get('user_name')).first()
if user:
# 用户已存在于数据库，抛出异常
raise forms.ValidationError({'user_name': '该用户已存在'})
# 校验密码是否相等
pwd = self.cleaned_data.get('pwd')
cpwd = self.cleaned_data.get('cpwd')
if pwd != cpwd:
raise forms.ValidationError({'pwd': '两次密码不一致'})
return self.cleaned_data
class UserLoginForm(forms.Form):
username = forms.CharField(required=True,
error_messages={
'required': '用户名必填',
})
pwd = forms.CharField(required=True,
error_messages={
'required': '密码必填',
})
# def clean(self):
# 验证登录的账号是否已经被注册过，注册过才能登录
# user = User.objects.filter(username=self.cleaned_data.get('username')).first()
# if not user:
# raise forms.ValidationError({'username': '该账号没有注册'})
#
# return self.cleaned_data
class UserAddressForm(forms.Form):
signer_name = forms.CharField(required=True,
error_messages={
'required': '收件人必填'
})
address = forms.CharField(required=True,
error_messages={
'required': '必填'
})
postcode = forms.CharField(required=True,
error_messages={
'required': '邮编必填'
})
mobile = forms.CharField(required=True,
error_messages={
'required': '手机必填'
})

def user_center_site(request):
if request.method == 'GET':
user_id = request.session.get('user_id')
user_address = UserAddress.objects.filter(user_id=user_id)
return render(request, 'user_center_site.html', {'user_address': user_address})
if request.method == 'POST':
# 使用表单做校验
form = UserAddressForm(request.POST)
if form.is_valid():
user_id = request.session.get('user_id')
address = form.cleaned_data['address']
signer_name = form.cleaned_data['signer_name']
postcode = form.cleaned_data['postcode']
mobile = form.cleaned_data['mobile']
UserAddress.objects.create(user_id=user_id, address=address, signer_name=signer_name,
signer_postcode=postcode, signer_mobile=mobile)
return HttpResponseRedirect(reverse('user:user_center_site'))
else:
errors = form.errors
return render(request, 'user_center_site.html', {'errors': errors})
