第12次09：展示收货地址和新增地址
第1步：定义地址模型，考虑到地址模型中的创建时间与更新时间在后续其它模型中也会用到，所以先定义一个包含创建时间和更新时间的基础模型BaseModel.py，其它模型通过继承它来获取创建时间和更新时间属性。
在utils包中创建models.py，并定义BaseModel模型
from django.db import modelsclass BaseModel(models.Model):"""本项目中地址、商品后续涉及到创建时间和更新时间的模型的基类"""create_time = models.DateTimeField(verbose_name='创建时间', auto_now_add=True)update_time = models.DateTimeField(verbose_name='更新时间', auto_now=True)class Meta:abstract = True # 不能实例化表
第2步：在users应用的下的models.py创建地址模型，此模型继承BaseModel，注意Address模型在放在User模型的下面，否则无法正确使用Use的模型作为外键
from xiaoyu_mall.utils.models import BaseModelclass Address(BaseModel):"""收货地址"""user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='addresses', verbose_name='用户')title = models.CharField(verbose_name='地址名称', max_length=20)receiver = models.CharField(verbose_name='收货人', max_length=20)province = models.ForeignKey('areas.Area', on_delete=models.PROTECT, related_name='province_addresses',verbose_name='省')city = models.ForeignKey('areas.Area', on_delete=models.PROTECT, related_name='city_addresses', verbose_name='市')district = models.ForeignKey('areas.Area', on_delete=models.PROTECT, related_name='district_addresses',verbose_name='区')place = models.CharField(verbose_name='地址', max_length=50)mobile = models.CharField(verbose_name='手机号', max_length=11)tel = models.CharField(verbose_name='固定电话', max_length=20, null=True, blank=True, default='')email = models.CharField(verbose_name='电子邮箱', max_length=30, null=True, blank=True, default='')is_deleted = models.BooleanField(default=False, verbose_name='逻辑删除')class Meta:db_table = 'tb_address'verbose_name = '用户地址'verbose_name_plural = verbose_nameordering = ['-update_time'] # 按更新时间倒序排列
第3步：在User模型中添加默认收货地址的字段default_address
class User(AbstractUser):...# 新增字段default_address = models.ForeignKey('Address', on_delete=models.SET_NULL, null=True, blank=True,related_name='users', verbose_name='默认地址')
第4步：生成并执行迁移文件
python .\manage.py makemigrations
python .\manage.py makemigrations
python .\manage.py migrate
第5步：在users应用下定义展示地址的视图
class AddressView(LoginRequiredMixin, View):"""展示地址"""def get(self, request):"""提供收货地址界面"""login_user = request.user # 获取当前登录用户对象addresses = Address.objects.filter(user=login_user, is_deleted=False)address_list = [] # 将用户地址模型列表转字典列表for address in addresses:address_dict = {"id": address.id, "title": address.title,"receiver": address.receiver, "city": address.city.name,"province": address.province.name, "place": address.place,"district": address.district.name, "tel": address.tel,"mobile": address.mobile, "email": address.email}address_list.append(address_dict)context = {'default_address_id': login_user.default_address_id or '0','addresses': address_list,'address_num': constants.USER_ADDRESS_COUNTS_LIMIT}return render(request, 'user_center_site.html', context)
第6步：配置路由，users/urls.py
path('addresses/', views.AddressView.as_view(), name='address'),
第7步：导入模板user_center_site.html

第8步：在users应用下定义AddressCreateView，用于实现新增地址的功能。
class AddressCreateView(LoginRequiredJSONMixin, View):"""展示地址"""def get(self, request):"""提供收货地址界面"""login_user = request.user # 获取当前登录用户对象addresses = Address.objects.filter(user=login_user,is_deleted=False)address_list = [] # 将用户地址模型列表转字典列表for address in addresses:address_dict = {"id": address.id, "title": address.title,"receiver": address.receiver, "city": address.city.name,"province": address.province.name, "place": address.place,"district": address.district.name, "tel": address.tel,"mobile": address.mobile, "email": address.email}address_list.append(address_dict)context = {'default_address_id': login_user.default_address_id or '0','addresses': address_list}return render(request, 'user_center_site.html', context)def post(self, request):"""新增收货地址"""# 校验用户收货地址数量count = request.user.addresses.filter(is_deleted__exact=False).count()if count >= constants.USER_ADDRESS_COUNTS_LIMIT:return JsonResponse({"code": RETCODE.THROTTLINGERR, 'errmsg': "超出用户地址数量上限"})json_dict = json.loads(request.body.decode())receiver = json_dict.get('receiver')province_id = json_dict.get('province_id')city_id = json_dict.get('city_id')district_id = json_dict.get('district_id')place = json_dict.get('place')mobile = json_dict.get('mobile')tel = json_dict.get('tel')email = json_dict.get('email')# 校验参数if not all([receiver, province_id, city_id, district_id, place, mobile]):return HttpResponseForbidden('缺少必传参数')if not re.match(r'^1[3-9]\d{9}$', mobile):return HttpResponseForbidden('参数mobile有误')if tel:if not re.match(r'^(0[0-9]{2,3}-)?([2-9][0-9]{6,7})+(-[0-9]{1,4})?$', tel):return HttpResponseForbidden('参数tel有误')if email:if not re.match(r'^[a-z0-9][\w\\.\-]*@[a-z0-9\-]+(\.[a-z]{2,5}){1,2}$', email):return HttpResponseForbidden('参数email有误')# 保存收货地址try:address = Address.objects.create(user=request.user, title=receiver, receiver=receiver,province_id=province_id, place=place, tel=tel,city_id=city_id, district_id=district_id,mobile=mobile, email=email)# 设置默认收货地址if not request.user.default_address:request.user.default_address = addressrequest.user.save()except Exception as e:logger.error(e)return JsonResponse({'code': RETCODE.DBERR, 'errmsg': '新增地址失败'})# 返回响应，新增地址成功，将新增的地址响应给前端实现局部刷新 构造新增地址字典数据address_dict = {"id": address.id, "title": address.title,"receiver": address.receiver, "province": address.province.name,"city": address.city.name, "district": address.district.name,"place": address.place, "mobile": address.mobile,"tel": address.tel, "email": address.email}# 响应新增地址结果：需要将新增的地址返回给前端渲染return JsonResponse({'code': RETCODE.OK,'errmsg': '新增地址成功', 'address': address_dict})
第9步：在users应用下配置路由
path('addresses/create/', views.AddressCreateView.as_view()),
