1.新建django项目newnet
1.新建项目newnet,新建app:users:
虚拟环境选个能用的
2.新建mysql数据库newnet:
打开mysql终端:
show databases; --查看所有数据库 create database newnet default character set utf8 collate utf8_general_ci; --创建数据库gg,因为创建数据表内有中文字段,所以要加default show databases; --查看所有数据库
3.连接数据库:
1.在settings.py中:
DATABASES = { ‘default‘: { ‘ENGINE‘: ‘django.db.backends.mysql‘, ‘NAME‘: ‘newnet‘, ‘USER‘:‘root‘, ‘PASSWORD‘:‘数据库密码‘, ‘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newnet/newnet/__init__.py中加代码:
import pymysql pymysql.install_as_MySQLdb()
4.新建app
1.新建app:good、trade、user_operation
python manage.py startapp good python manage.py startapp trade python manage.py startapp user_operation
2.在settings.py中配置app:
INSTALLED_APPS = [ ‘django.contrib.admin‘, ‘django.contrib.auth‘, ‘django.contrib.contenttypes‘, ‘django.contrib.sessions‘, ‘django.contrib.messages‘, ‘django.contrib.staticfiles‘, ‘users.apps.UsersConfig‘, ‘good.apps.GoodConfig‘, ‘trade.apps.TradeConfig‘, ‘user_operation.apps.UserOperationConfig‘ ]
5.新建目录 静态文件目录static,媒体文件目录media:
1.新建两个目录
2.在settings中配置路径:
STATIC_URL = ‘/static/‘ STATIC_ROOT = os.path.join(BASE_DIR, ‘static‘) MEDIA_URL=‘/media/‘ MEDIA_ROOT=os.path.join(BASE_DIR,‘media‘)
3.在newnet/urls.py中配置媒体文件路径:
from django.contrib import admin from django.urls import path from django.views.static import serve from newnet.settings import MEDIA_ROOT urlpatterns = [ path(‘admin/‘, admin.site.urls), path(‘media/<path:path>‘,serve,{‘document_root‘:MEDIA_ROOT}), ]
6.整理项目目录:
1.新建apps包用来存放我们新建的app,将users、good、trade、user_operation拖入。
2.新建extra_apps包,用来存放第三方包。
3.mark路径(apps和extra_apps都要mark)
3.settings中配置:
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.导入第三方包xadmin和DjangoUeditor
