4、xadmin後臺管理

4.1.xadmin添加富文本插件

（1）xadmin/plugins文件夾下新建文件ueditor.py

代碼以下：

# xadmin/plugins/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）把插件添加到__init__.py裏面

# xadmin/plugins/__init__.py

PLUGINS = (
    'ueditor',
)

4.2.url配置

配置xadmin和ueditor的路由

# MxShop/urls.py

import xadmin

from django.urls import path,include

urlpatterns = [
    path('xadmin/', xadmin.site.urls),
    path('ueditor/', include('DjangoUeditor.urls')),
]

 

4.3.註冊app到xadmin後臺

四個app下面都新建文件adminx.py，而後分別註冊到後臺

（1）users/adminx.py

# users/adminx.py
__author__ = 'derek'

import xadmin
from xadmin import views
from .models import VerifyCode


class BaseSetting(object):
    #添加主題功能
    enable_themes = True
    use_bootswatch = True


class GlobalSettings(object):
    #全局配置，後臺管理標題和頁腳
    site_title = "仙劍奇俠傳"
    site_footer = "http://www.cnblogs.com/derek1184405959/"
    #菜單收縮
    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名字爲中文

# users/apps.py

from django.apps import AppConfig


class UsersConfig(AppConfig):
    name = 'users'
    #app名字後臺顯示中文
    verbose_name = "用戶管理"

還須要__init__.py中修改默認配置才生效

# users/__init__.py

default_app_config = 'users.apps.UsersConfig'

 

其它三個app同樣的操做

（2）goods/adminx.py

# goods/adminx.py

import xadmin
from .models import Goods, GoodsCategory, GoodsImage, GoodsCategoryBrand, Banner, HotSearchWords
from .models import IndexAd


class GoodsAdmin(object):
    #顯示的列
    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"]
    #能夠搜索的字段
    search_fields = ['name', ]
    #列表頁能夠直接編輯的
    list_editable = ["is_hot", ]
    #過濾器
    list_filter = ["name", "click_num", "sold_num", "fav_num", "goods_num", "market_price",
                   "shop_price", "is_new", "is_hot", "add_time", "category__name"]
    #富文本編輯器
    style_fields = {"goods_desc": "ueditor"}

    #在添加商品的時候能夠添加商品圖片
    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)

 

# goods/apps.py

from django.apps import AppConfig

class GoodsConfig(AppConfig):
    name = 'goods'
    verbose_name = '商品管理'

# good/__init__.py

default_app_config = 'goods.apps.GoodsConfig'

 

（3）trade/adminx.py

# trade/adminx.py
__author__ = 'derek'

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)

 

# trade/apps.py

from django.apps import AppConfig


class TradeConfig(AppConfig):
    name = 'trade'
    verbose_name = '交易管理'

# trade/__init__.py

default_app_config = 'trade.apps.TradeConfig'

 

（4）user_operation/adminx.py

# user_operation/adminx.py
__author__ = 'derek'


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)

 

# user_operation/apps.py

from django.apps import AppConfig


class UserOperationConfig(AppConfig):
    name = 'user_operation'
    verbose_name = '操做管理'

# user_operation/__init__.py

default_app_config = 'user_operation.apps.UserOperationConfig'

（5）生成數據庫表

python manage.py makemigrations

python manage.py migrate

 

4.4.導入商品類別數據

因爲分類和商品不少，就寫個腳本導入數據

單獨使用django的model,批量導入數據

• db_tools下新建文件夾data，而後把前端的json文件（category_data和product_data）拷貝到裏面
•  把brands和goods圖片拷貝到media目錄下

db_tools下新建文件 import_category_data.py

代碼以下：

# db_tools/data/import_category_data.py

#獨立使用django的model
import sys
import os

#獲取當前文件的路徑（運行腳本）
pwd = os.path.dirname(os.path.realpath(__file__))
#獲取項目的跟目錄
sys.path.append(pwd+"../")
#要想單獨使用django的model，必須指定一個環境變量，會去settings配置找
#參照manage.py裏面就知道爲何這樣設置了
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "MxShop.settings")

import django
django.setup()

from goods.models import GoodsCategory

from db_tools.data.category_data import row_data

#一級類
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
    #保存到數據庫
    lev1_intance.save()
#二級類
    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()
#三級類
        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()

而後運行腳本 import_category_data.py  數據就能夠保存到數據庫了

 

4.5.導入商品

 在data目錄下新建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」，數據庫中是float類型，因此要替換掉
    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 ""
    # 取第一張做爲封面圖
    goods.goods_front_image = goods_detail["images"][0] if goods_detail["images"] else ""
    #取最後一個
    category_name = goods_detail["categorys"][-1]
    # 取出當前子類對應的GoodsCategory對象，filter沒有匹配的會返回空數組，不會拋異常。
    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()

 

而後運行，把商品生產到數據庫中

配置media路徑

settings中

# 設置上傳文件的路徑
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_ROOT

urlpatterns = [
    path('xadmin/', xadmin.site.urls),
    path('ueditor/',include('DjangoUeditor.urls' )),
    #文件
    path('media/<path:path>',serve,{'document_root':MEDIA_ROOT}),
]
