四、xadmin后台管理

4.1.xadmin添加富文本插件

（1）xadmin/plugins文件夹下新建文件ueditor.py

代码如下：

# xadmin/plugins/ueditor.pyimport xadmin
from xadmin.views import BaseAdminPlugin, CreateAdminView, ModelFormAdminView, UpdateAdminView
from DjangoUeditor.models import UEditorField
from DjangoUeditor.widgets import UEditorWidget
from django.conf import settingsclass XadminUEditorWidget(UEditorWidget):def __init__(self, **kwargs):self.ueditor_options = kwargsself.Media.js = Nonesuper(XadminUEditorWidget,self).__init__(kwargs)class UeditorPlugin(BaseAdminPlugin):def get_field_style(self, attrs, db_field, style, **kwargs):if style == 'ueditor':if isinstance(db_field, UEditorField):widget = db_field.formfield().widgetparam = {}param.update(widget.ueditor_settings)param.update(widget.attrs)return {'widget':XadminUEditorWidget(**param)}return attrsdef block_extrahead(self, context, nodes):js  = '<script type="text/javascript" src="%s"></script>' %(settings.STATIC_URL + "ueditor/ueditor.config.js")js += '<script type="text/javascript" src="%s"></script>' %(settings.STATIC_URL + "ueditor/ueditor.all.min.js")nodes.append(js)xadmin.site.register_plugin(UeditorPlugin, UpdateAdminView)
xadmin.site.register_plugin(UeditorPlugin, CreateAdminView)

（2）把插件添加到__init__.py里面

# xadmin/plugins/__init__.pyPLUGINS = ('ueditor',
)

4.2.url配置

配置xadmin和ueditor的路由

# MxShop/urls.pyimport xadminfrom django.urls import path,includeurlpatterns = [path('xadmin/', xadmin.site.urls),path('ueditor/', include('DjangoUeditor.urls')),
]

4.3.注册app到xadmin后台

四个app下面都新建文件adminx.py，然后分别注册到后台

（1）users/adminx.py

# users/adminx.py
__author__ = 'derek'import xadmin
from xadmin import views
from .models import VerifyCodeclass BaseSetting(object):#添加主题功能enable_themes = Trueuse_bootswatch = Trueclass GlobalSettings(object):#全局配置，后台管理标题和页脚site_title = "仙剑奇侠传"site_footer = "http://www.cnblogs.com/derek1184405959/"#菜单收缩menu_style = "accordion"class VerifyCodeAdmin(object):list_display = ['code', 'mobile', "add_time"]xadmin.site.register(VerifyCode, VerifyCodeAdmin)
xadmin.site.register(views.BaseAdminView, BaseSetting)
xadmin.site.register(views.CommAdminView, GlobalSettings)

修改app名字为中文

# users/apps.pyfrom django.apps import AppConfigclass UsersConfig(AppConfig):name = 'users'#app名字后台显示中文verbose_name = "用户管理"

还需要__init__.py中修改默认配置才生效

# users/__init__.pydefault_app_config = 'users.apps.UsersConfig'

其它三个app一样的操作

（2）goods/adminx.py

# goods/adminx.pyimport xadmin
from .models import Goods, GoodsCategory, GoodsImage, GoodsCategoryBrand, Banner, HotSearchWords
from .models import IndexAdclass GoodsAdmin(object):#显示的列list_display = ["name", "click_num", "sold_num", "fav_num", "goods_num", "market_price","shop_price", "goods_brief", "goods_desc", "is_new", "is_hot", "add_time"]#可以搜索的字段search_fields = ['name', ]#列表页可以直接编辑的list_editable = ["is_hot", ]#过滤器list_filter = ["name", "click_num", "sold_num", "fav_num", "goods_num", "market_price","shop_price", "is_new", "is_hot", "add_time", "category__name"]#富文本编辑器style_fields = {"goods_desc": "ueditor"}#在添加商品的时候可以添加商品图片class GoodsImagesInline(object):model = GoodsImageexclude = ["add_time"]extra = 1style = 'tab'inlines = [GoodsImagesInline]class GoodsCategoryAdmin(object):list_display = ["name", "category_type", "parent_category", "add_time"]list_filter = ["category_type", "parent_category", "name"]search_fields = ['name', ]class GoodsBrandAdmin(object):list_display = ["category", "image", "name", "desc"]def get_context(self):context = super(GoodsBrandAdmin, self).get_context()if 'form' in context:context['form'].fields['category'].queryset = GoodsCategory.objects.filter(category_type=1)return contextclass BannerGoodsAdmin(object):list_display = ["goods", "image", "index"]class HotSearchAdmin(object):list_display = ["keywords", "index", "add_time"]class IndexAdAdmin(object):list_display = ["category", "goods"]xadmin.site.register(Goods, GoodsAdmin)
xadmin.site.register(GoodsCategory, GoodsCategoryAdmin)
xadmin.site.register(Banner, BannerGoodsAdmin)
xadmin.site.register(GoodsCategoryBrand, GoodsBrandAdmin)xadmin.site.register(HotSearchWords, HotSearchAdmin)
xadmin.site.register(IndexAd, IndexAdAdmin)

# goods/apps.pyfrom django.apps import AppConfigclass GoodsConfig(AppConfig):name = 'goods'verbose_name = '商品管理'

# good/__init__.pydefault_app_config = 'goods.apps.GoodsConfig'

（3）trade/adminx.py

# trade/adminx.py
__author__ = 'derek'import xadmin
from .models import ShoppingCart, OrderInfo, OrderGoodsclass ShoppingCartAdmin(object):list_display = ["user", "goods", "nums", ]class OrderInfoAdmin(object):list_display = ["user", "order_sn",  "trade_no", "pay_status", "post_script", "order_mount","order_mount", "pay_time", "add_time"]class OrderGoodsInline(object):model = OrderGoodsexclude = ['add_time', ]extra = 1style = 'tab'inlines = [OrderGoodsInline, ]xadmin.site.register(ShoppingCart, ShoppingCartAdmin)
xadmin.site.register(OrderInfo, OrderInfoAdmin)

# trade/apps.pyfrom django.apps import AppConfigclass TradeConfig(AppConfig):name = 'trade'verbose_name = '交易管理'

# trade/__init__.pydefault_app_config = 'trade.apps.TradeConfig'

（4）user_operation/adminx.py

# user_operation/adminx.py
__author__ = 'derek'import xadmin
from .models import UserFav, UserLeavingMessage, UserAddressclass UserFavAdmin(object):list_display = ['user', 'goods', "add_time"]class UserLeavingMessageAdmin(object):list_display = ['user', 'message_type', "message", "add_time"]class UserAddressAdmin(object):list_display = ["signer_name", "signer_mobile", "district", "address"]xadmin.site.register(UserFav, UserFavAdmin)
xadmin.site.register(UserAddress, UserAddressAdmin)
xadmin.site.register(UserLeavingMessage, UserLeavingMessageAdmin)

# user_operation/apps.pyfrom django.apps import AppConfigclass UserOperationConfig(AppConfig):name = 'user_operation'verbose_name = '操作管理'

# user_operation/__init__.pydefault_app_config = 'user_operation.apps.UserOperationConfig'

（5）生成数据库表

python manage.py makemigrationspython manage.py migrate

4.4.导入商品类别数据

由于分类和商品很多，就写个脚本导入数据

单独使用django的model,批量导入数据

db_tools下新建文件夹data，然后把前端的json文件（category_data和product_data）拷贝到里面
把brands和goods图片拷贝到media目录下

db_tools下新建文件 import_category_data.py

代码如下：

# db_tools/data/import_category_data.py#独立使用django的model
import sys
import os#获取当前文件的路径（运行脚本）
pwd = os.path.dirname(os.path.realpath(__file__))
#获取项目的跟目录
sys.path.append(pwd+"../")
#要想单独使用django的model，必须指定一个环境变量，会去settings配置找
#参照manage.py里面就知道为什么这样设置了
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "MxShop.settings")import django
django.setup()from goods.models import GoodsCategoryfrom db_tools.data.category_data import row_data#一级类
for lev1_cat in row_data:lev1_intance = GoodsCategory()lev1_intance.code = lev1_cat["code"]lev1_intance.name = lev1_cat["name"]lev1_intance.category_type = 1#保存到数据库lev1_intance.save()
#二级类for lev2_cat in lev1_cat["sub_categorys"]:lev2_intance = GoodsCategory()lev2_intance.code = lev2_cat["code"]lev2_intance.name = lev2_cat["name"]lev2_intance.category_type = 2lev2_intance.parent_category = lev1_intancelev2_intance.save()
#三级类for lev3_cat in lev2_cat["sub_categorys"]:lev3_intance = GoodsCategory()lev3_intance.code = lev3_cat["code"]lev3_intance.name = lev3_cat["name"]lev3_intance.category_type = 3lev3_intance.parent_category = lev2_intancelev3_intance.save()

然后运行脚本 import_category_data.py 数据就可以保存到数据库了

4.5.导入商品

在data目录下新建import_goods_data.py

import sys
import ospwd = os.path.dirname(os.path.realpath(__file__))
sys.path.append(pwd+"../")
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "MxShop.settings")import django
django.setup()from goods.models import Goods, GoodsCategory, GoodsImagefrom db_tools.data.product_data import row_datafor goods_detail in row_data:goods = Goods()goods.name = goods_detail["name"]#前端中是“￥232”，数据库中是float类型，所以要替换掉goods.market_price = float(int(goods_detail["market_price"].replace("￥", "").replace("元", "")))goods.shop_price = float(int(goods_detail["sale_price"].replace("￥", "").replace("元", "")))goods.goods_brief = goods_detail["desc"] if goods_detail["desc"] is not None else ""goods.goods_desc = goods_detail["goods_desc"] if goods_detail["goods_desc"] is not None else ""# 取第一张作为封面图goods.goods_front_image = goods_detail["images"][0] if goods_detail["images"] else ""#取最后一个category_name = goods_detail["categorys"][-1]# 取出当前子类对应的GoodsCategory对象，filter没有匹配的会返回空数组，不会抛异常。category = GoodsCategory.objects.filter(name=category_name)if category:goods.category = category[0]goods.save()for goods_image in goods_detail["images"]:goods_image_instance = GoodsImage()goods_image_instance.image = goods_imagegoods_image_instance.goods = goodsgoods_image_instance.save()

然后运行，把商品生产到数据库中

配置media路径

settings中

# 设置上传文件的路径
MEDIA_URL="/media/"
MEDIA_ROOT=os.path.join(BASE_DIR,"media")

urls.py

# MxShop/urls.py
__author__ = 'derek'from django.urls import path,include
import xadmin
from django.views.static import serve
from MxShop.settings import MEDIA_ROOTurlpatterns = [path('xadmin/', xadmin.site.urls),path('ueditor/',include('DjangoUeditor.urls' )),#文件path('media/<path:path>',serve,{'document_root':MEDIA_ROOT}),
]
