【Vue+DRF 生鲜电商】xadmin 后台管理（二）
1. xadmin 添加富文本插件
在 xadmin 中添加插件，使其能够支持富文本。
1、xadmin/plugins 新建 ueditor.py：
import xadmin
from xadmin.views import BaseAdminPlugin, CreateAdminView, ModelFormAdminView, UpdateAdminView
from DjangoUeditor.models import UEditorField
from DjangoUeditor.widgets import UEditorWidget
from django.conf import settings
class XadminUEditorWidget(UEditorWidget):
def __init__(self, **kwargs):
self.ueditor_options = kwargs
self.Media.js = None
super(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().widget
param = {}
param.update(widget.ueditor_settings)
param.update(widget.attrs)
return {'widget': XadminUEditorWidget(**param)}
return attrs
def 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、将插件添加到 xadmin/plugins/__init__.py：
PLUGINS = (
'actions',
'filters',
...
'ueditor',
)
2. 配置 xadmin 后台
2.1 用户 users
1、新建 apps/users/adminx.py：
import xadmin
from xadmin import views
from .models import VerifyCord
class BaseSetting(object):
"""添加主题功能"""
enable_themes = True
use_bootswatch = True
class GlobalSetting(object):
"""全局配置，后台管理标题和页脚"""
site_title = 'Hubery_Jun'
site_footer = 'https://www.bilibili.com'
menu_style = 'accordion' # 菜单收缩
class VerifyCodeAdmin(object):
list_display = ['code', 'mobile', 'add_time']
xadmin.site.register(VerifyCord, VerifyCodeAdmin)
xadmin.site.register(views.BaseAdminView, BaseSetting)
xadmin.site.register(views.CommAdminView, GlobalSetting)
2、修改 app 名称为中文 users/apps.py：
from django.apps import AppConfig
class UsersConfig(AppConfig):
name = 'users'
# 设置 app 名字为中文，admin 中
verbose_name = '用户管理'
3、修改默认配置 users/__init__.py：
default_app_config = 'users.apps.UsersConfig'
其他三个 APP 配置类似。
2.2 商品 goods
1、新建 apps/goods/adminx.py：
import xadmin
from .models import Goods, GoodsCategory, GoodsImage, GoodsCategoryBrand, Banner, HotSearchWords
from .models import IndexAd
class 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 = GoodsImage
exclude = ["add_time"]
extra = 1
style = '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 context
class 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)
2、修改 app 名称为中文 goods/apps.py：
from django.apps import AppConfig
class UsersConfig(AppConfig):
name = 'goods'
# 设置 app 名字为中文，admin 中
verbose_name = '商品管理'
3、修改默认配置 goods/__init__.py：
default_app_config = 'goods.apps.GoodsConfig'
2.3 交易 trade
1、新建 apps/trade/adminx.py：
import xadmin
from .models import ShoppingCart, OrderInfo, OrderGoods
class 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 = OrderGoods
exclude = ['add_time', ]
extra = 1
style = 'tab'
inlines = [OrderGoodsInline, ]
xadmin.site.register(ShoppingCart, ShoppingCartAdmin)
xadmin.site.register(OrderInfo, OrderInfoAdmin)
2、修改 app 名称为中文 trade/apps.py：
from django.apps import AppConfig
class UsersConfig(AppConfig):
name = 'trade'
# 设置 app 名字为中文，admin 中
verbose_name = '交易管理'
3、修改默认配置 trade/__init__.py：
default_app_config = 'trade.apps.TradeConfig'
2.4 用户操作 user_operation
1、新建 apps/user_operation/adminx.py：
import xadmin
from .models import UserFav, UserLeavingMessage, UserAddress
class 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)
2、修改 app 名称为中文 user_operation/apps.py：
from django.apps import AppConfig
class UsersConfig(AppConfig):
name = 'user_operation'
# 设置 app 名字为中文，admin 中
verbose_name = '操作管理'
3、修改默认配置 user_operation/__init__.py：
default_app_config = 'user_operation.apps.UserOperationConfig'
3. 导入数据
db_tools 下新建目录 data，将 category_data.py 和product_data.py 拷贝到目录中。另外将相关图片拷贝到 media 目录中。
3.1 导入分类信息
新建 db_tools/import_category_data.py：
# 独立使用django的model
import sys
import os
# 获取当前文件的路径，以及路径的父级文件夹名
pwd = os.path.dirname(os.path.realpath(__file__))
# 将项目目录加入setting
sys.path.append(pwd + "../")
# manage.py中
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "MxShop.settings")
import django
django.setup()
# 这行代码必须在初始化django之后
from goods.models import GoodsCategory
from db_tools.data.category_data import row_data
# 一级分类
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
lev1_intance.save()
# 二级分类
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 = 2
lev2_intance.parent_category = lev1_intance
lev2_intance.save()
# 三级分类
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 = 3
lev3_intance.parent_category = lev2_intance
lev3_intance.save()
3.2 导入商品信息
新建 db_tools\import_goods_data.py：
import sys
import os
pwd = 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, GoodsImage
from db_tools.data.product_data import row_data
for 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_image
goods_image_instance.goods = goods
goods_image_instance.save()
运行项目，访问 http://127.0.0.1:8000/xadmin/ 即可进行后台管理。
