（生鲜项目）04. 导入数据

第一步: copy文件, 设置路径

把brands和goods文件夹copy到以下路径, 并配置好相应字段的upload to

 

 

第二步: 导入GoodsCategory

准备独立使用models模块, 来一次性导入大量的 "goods.models.GoodsCategory" 数据

为什么不先导入Goods? 因为Goods里有GoodsCategory的外键

先把源文件 category_data.py 和 product_data.py 复制到如下路径, 然后手动新建import_category_data和import_product_data

 import_category_data.py

# 独立使用django的model模块
import sys,os

# from users.models import UserProfile
# 如果在配置DJANGO_SETTINGS_MODULE之前导入了与django有关的模块,会报错,见下面的截图:
# "You must either define the environment variable DJANGO_SETTINGS_MODULE"

# 把项目根路径加到系统环境变量中去
pwd=os.path.dirname(os.path.abspath(__file__))
sys.path.append(pwd+"../")

# 导入settings文件
os.environ.setdefault("DJANGO_SETTINGS_MODULE","MxShop.settings")

# django初始化
import django
django.setup()

from goods.models import GoodsCategory

from db_tools.data.category_data import row_data

for lev1_cat in row_data:
    lev1_instance = GoodsCategory()
    lev1_instance.name = lev1_cat["name"]
    lev1_instance.code = lev1_cat["code"]
    lev1_instance.category_type = 1
    lev1_instance.save()
    for lev2_cat in lev1_cat["sub_categorys"]:
        lev2_instance = GoodsCategory()
        lev2_instance.name = lev2_cat["name"]
        lev2_instance.code = lev2_cat["code"]
        lev2_instance.category_type = 2
        lev2_instance.parent_category = lev1_instance
        lev2_instance.save()
        for lev3_cat in lev2_cat["sub_categorys"]:
            lev3_instance = GoodsCategory()
            lev3_instance.name = lev3_cat["name"]
            lev3_instance.code = lev3_cat["code"]
            lev3_instance.category_type = 3
            lev3_instance.parent_category = lev2_instance
            lev3_instance.save()

 

接下来执行该文件, 就可以发现数据库中自动填充了很多数据, 一共120条, 一级类目有8个

 

 

第三步: 导入Goods

准备独立使用models模块, 来一次性导入

 import_product_data.py

# 独立使用django的model模块
import sys,os

# 把项目根路径加到系统环境变量中去
pwd=os.path.dirname(os.path.abspath(__file__))
sys.path.append(pwd+"../")

# 导入settings文件
os.environ.setdefault("DJANGO_SETTINGS_MODULE","MxShop.settings")

# django初始化
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"]
    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 ""
    goods.goods_front_image = goods_detail["images"][0] if goods_detail["images"] else ""

    category_name = goods_detail["categorys"][-1]
    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()

接下来去数据库和xadmin后台验证, 检查是否是52条数据

可以发现, 商品描述里面的图片是破图, 是因为还没有配置MEDIA, 现在去设置

 

 settings.py

MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR,'media')

urls.py

from django.conf.urls import url
import xadmin
from MxShop.settings import MEDIA_ROOT
from django.views.static import serve

urlpatterns = [
    url(r'^xadmin/', xadmin.site.urls),
    url(r'^media/(?P<path>.*)$', serve, {"document_root": MEDIA_ROOT}),
]

再刷新页面, 破图恢复正常了
