1.开发环境配置

Windows7 64位旗舰版

python3.6

node.js

mysql

navicat

pycharm

webstorm或vscode

2.项目初始化

　　新版的pycharm很贴心的让每一个新的项目，都自动会在一个虚拟环境中，放心的新建项目就可以了，不用考虑虚拟环境的事儿了

1.新建Django项目，项目名为MxShop，新建app命名为users

2.修改django版本与安装djangorestframework

　　使用新版的pycharm新建django项目，因为每一次pycharm都会新建一个虚拟环境，将项目所需的所有模块下载到最新版本，然后放到虚拟环境里，所以，每次用pycharm新建django项目，则pycharm都会下载最新版本的django，我在写这篇博客时，django最新已经更新到2.1.1了，但是，djangorestframework目前只支持到django2.0，如果在django2.1的项目下安装djangorestframework亲测有坑，会报错的。

　　so！将django的版本，从最新版本的2.1.1改为2.0

 

python -m django --version
pip install django==2.0

 

然后安装djangorestframework及其依赖包markdown、django-filter

pip install djangorestframework markdown django-filter

安装 pillow包（做图片处理的）

pip install pillow

 

3.将database（数据库），改成mysql驱动

1.在settings.py里配置

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'mxshop',
        'USER':'root',
        'PASSWORD':'你的mysql密码',
        'HOST':'127.0.0.1',
        "OPTIONS":{"init_command":"SET default_storage_engine=INNODB;"}#第三方登录功能必须加上
    }
}

2.安装PyMYSQL

pip install PyMYSQL

3.在MxShop/__init__.py中加入代码

import pymysql
pymysql.install_as_MySQLdb()

4.在mysql操作界面中新建mxshop数据库

show databases;#查看数据库
create database mxshop;#新建数据库mxshop

4.整理一下项目结构

1.新建

1.新建apps包用来存放我们新建的app，将users拖入。

2.新建extra_apps包，用来存放第三方包。

3.新建media文件夹，用来存放文件

4.新建db_tools文件夹，用来放一些外部脚本

2.mark路径

在apps和extra_apps上分别，右键→Mark Directory as→Sources Root

3.settings中加代码配置路径

import sys
sys.path.insert(0,BASE_DIR)
sys.path.insert(0,os.path.join(BASE_DIR,'apps'))
sys.path.insert(0,os.path.join(BASE_DIR,'extra_apps'))

4.在settings中配置media路径

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

 

 3.Model设计

1.新建goods、trade、user_operation三个app，并且在settings中注册

打开终端，执行新建app命令

python manage.py startapp goods
python manage.py startapp trade
python manage.py startapp user_operation

 

 将新建的app拖入apps包

 

在settings.py中注册app

 2.设计users的models.py

1.models.py

from datetime import datetime

from django.db import models
from django.contrib.auth.models import AbstractUser

# Create your models here.


class UserProfile(AbstractUser):
    """
    用户
    """
    name=models.CharField(max_length=30,null=True,blank=True,verbose_name='姓名')
    birthday=models.DateField(null=True,blank=True,verbose_name='出生年月')
    mobile=models.CharField(max_length=6,choices=(('male','男'),('female','女')),default='female',verbose_name='性别')
    gender=models.CharField(max_length=11,verbose_name='电话')
    email = models.CharField(max_length=100,null=True,blank=True,verbose_name='邮箱')

    class Meta:
        verbose_name='用户'
        verbose_name_plural = verbose_name

    def __str__(self):
        return self.name


class VerifyCode(models.Model):
    """
    短信验证码
    """
    code=models.CharField(max_length=10,verbose_name='验证码')
    mobile=models.CharField(max_length=11,verbose_name='电话')
    add_time=models.DateTimeField(default=datetime.now,verbose_name='添加时间')

    class Meta:
        verbose_name='短信验证码'
        verbose_name_plural=verbose_name

    def __str__(self):
        return self.code

2.在settings.py中配置

AUTH_USER_MODEL='users.UserProfile'

 3.设计goods的models.py

1.DjangoUeditor富文本编辑框的安装与配置

1.将DjangoUeditor导入extra_apps中

#兼容python3+django2.0/2.1的DjangoUeditor
https://gitee.com/xueluoyihai/DjangoUeditor-for-python3-django2.0

 

 2.在settings中注册

3.在urls.py中

from django.contrib import admin
from django.urls import path

from django.views.static import serve
from MxShop.settings import MEDIA_ROOT
from django.urls import include


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

2.models.py

    search_fields = ['name', ]
    list_editable = ["is_hot", ]
    list_filter = ["name", "click_num", "sold_num", "fav_num", "goods_num", "market_price",
                   "shop_price", "is_new", "is_hot", "add_time", "category__name"]
    style_fields = {"goods_desc": "ueditor"}

    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)

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)

 

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)

3.安装和配置xadmin依赖包

1.安装依赖包 django-crispy-forms django-reversion django-formtools future httplib2 six django-import-export

pip install django-crispy-forms django-reversion django-formtools future httplib2 six django-import-export

2.在settings中注册

3.安装用来操作和导出Excel文件的包 xlwt xlsxwriter

pip install xlwt xlsxwriter

4.打开终端，执行数据更新命令，生成xadmin默认的表

python manage.py makemigrations
python manage.py migrate

5.配置url

import xadmin

urlpatterns = [
    path('xadmin/', xadmin.site.urls),
   #....
]

6.创建超级用户

python manage.py createsuperuser
Username: admin
邮箱: 1@1.com
Password:
Password (again):

 创建完毕，启动项目，然后访问

http://127.0.0.1:8000/xadmin/

就可以登录xadmin后台了，但是此时后台还是英文的。

7.将语言设定为中文

1.在settings中修改

LANGUAGE_CODE = 'zh-hans'

TIME_ZONE = 'Asia/Shanghai'

USE_I18N = True

USE_L10N = True

USE_TZ = False

 2.在每个app下的apps.py中做修改，加上verbose_name

goods/apps.py

from django.apps import AppConfig


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

trade/apps.py

from django.apps import AppConfig


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

users/apps.py

from django.apps import AppConfig


class UsersConfig(AppConfig):
    name = 'users'
    verbose_name='用户'

user_operation/apps.py

from django.apps import AppConfig


class UserOperationConfig(AppConfig):
    name = 'user_operation'
    verbose_name='用户操作'

 5.数据导入

1.导入商品类别数据

1.将项目资料中的brands目录和goods目录，导入media下

2.在db_tools目录下新建目录data，将项目资料中的category_data.py 和product_data.py导入

3.在db_tools下新建脚本文件：import_category_data.py

#独立使用django的model
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 GoodsCategory

from db_tools.data.category_data import row_data

for lev1_cat in row_data:

    lev1_intance.code = lev1_cat["code"]
    lev1_intance.name = lev1_cat["name"]
    lev1_intance.category_type = 1
    lev1_intance.save()

    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()

        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()

4.运行脚本，导入类别数据。到xadmin后台可以看到类别数据，已经导入了。

2.导入商品数据

1.在db_tools目录下，新建脚本：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"]
    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()

2.运行import_goods_data.py脚本，导入商品数据，在xadmin后台可以看到，商品数据导入成功了。
