1.1.项目结构搭建
(1)创建flask项目Perfect_bbs,然后搭建项目结构如下:
(2)构建蓝图
cms/views.py
# cmd/views.py from flask import Blueprint bp = Blueprint("cms",__name__,url_prefix='/cms') @bp.route('/') def index(): return 'cms index'
cms/init.py
from .views import bp
common/views.py
# common/views.py from flask import Blueprint bp = Blueprint("common",__name__,url_prefix='/common') @bp.route('/') def index(): return 'common index'
common/init.py
from .views import bp
front/views.py
# front/views.py from flask import Blueprint bp = Blueprint("front",__name__) @bp.route('/') def index(): return 'front index'
front/init.py
from .views import bp
config.py
DEBUG = True
Perfect_bbs.py
# Perfect_bbs.py from flask import Flask from apps.cms import bp as cms_bp from apps.front import bp as front_bp from apps.common import bp as common_bp import config app = Flask(__name__) app.config.from_object(config) #注册蓝图 app.register_blueprint(cms_bp) app.register_blueprint(front_bp) app.register_blueprint(common_bp) if __name__ == '__main__': app.run()
运行项目,浏览器访问
http://127.0.0.1:5000 http://127.0.0.1:5000/cms/ http://127.0.0.1:5000/common/
1.2.cms用户模型定义
建立CMS模型
(1)config.py
# config.py __author__ = 'derek' DEBUG = True DB_URI = "mysql+pymysql://root:123456@127.0.0.1:3306/bbs?charset=utf8" SQLALCHEMY_DATABASE_URI = DB_URI SQLALCHEMY_TRACK_MODIFICATIONS =False
(2)exts.py
# exts.py __author__ = 'derek' from flask_sqlalchemy import SQLAlchemy db = SQLAlchemy()
(3)cms/models.py
# cms/models.py __author__ = 'derek' from exts import db from datetime import datetime class CMSUser(db.Model): __tablename__='cms_user' id = db.Column(db.Integer,primary_key=True,autoincrement=True) username = db.Column(db.String(50),nullable=False) #不能为空 password = db.Column(db.String(100),nullable=False) email = db.Column(db.String(50),nullable=False,unique=True) #不能重复 join_time = db.Column(db.DateTime,default=datetime.now)
(4)manage.py
# manage.py __author__ = 'derek' from flask_script import Manager from flask_migrate import Migrate,MigrateCommand from Perfect_bbs import app from exts import db from apps.cms import models as cms_models manager = Manager(app) Migrate(app,db) #绑定app跟db manager.add_command('db',MigrateCommand) if __name__ == '__main__': manager.run()
(5)进cmd终端运行命令,生成到数据库
python manage.py db init # 初始化 python manage.py db migrate #创建迁移脚本 python manage.py db upgrade #生成到数据库
进数据库查看
项目下面也会多一个migrations目录
添加CMS用户
(1)Perfect_bbs.py
# Perfect_bbs.py __author__ = 'derek' from flask import Flask from apps.cms import bp as cms_bp from apps.front import bp as front_bp from apps.common import bp as common_bp import config from exts import db def create_app(): app = Flask(__name__) app.config.from_object(config) app.register_blueprint(cms_bp) app.register_blueprint(front_bp) app.register_blueprint(common_bp) db.init_app(app) return app if __name__ == '__main__': app = create_app() app.run()
(2)manage.py
# manage.py __author__ = 'derek' from flask_script import Manager from flask_migrate import Migrate,MigrateCommand from Perfect_bbs import create_app from exts import db from apps.cms import models as cms_models CMSUser = cms_models.CMSUser app = create_app() manager = Manager(app) Migrate(app,db) #绑定app跟db manager.add_command('db',MigrateCommand) @manager.option('-u','--username',dest='username') @manager.option('-p','--password',dest='password') @manager.option('-e','--email',dest='email') def create_cms_user(username,password,email): user = CMSUser(username=username,password=password,email=email) db.session.add(user) db.session.commit() print('cms用户添加成功') if __name__ == '__main__': manager.run()
(3)cmd终端添加用户
python manage.py create_cms_user -u derek -p 123456 -e 1184405959@qq.com
进数据库查看是否添加成功
发现密码是明文保存的,显然不行
密码加密
(1)cms/models.py
对外是‘passwor‘’显示,对内是”_password”
# cms/models.py __author__ = 'derek' from exts import db from datetime import datetime from werkzeug.security import generate_password_hash,check_password_hash class CMSUser(db.Model): __tablename__='cms_user' id = db.Column(db.Integer,primary_key=True,autoincrement=True) username = db.Column(db.String(50),nullable=False) #不能为空 _password = db.Column(db.String(100),nullable=False) email = db.Column(db.String(50),nullable=False,unique=True) #不能重复 join_time = db.Column(db.DateTime,default=datetime.now) def __init__(self,username,password,email): self.username = username self.password = password self.email = email @property def password(self): return self._password @password.setter def password(self,raw_password): self._password = generate_password_hash(raw_password) def check_password(self,raw_password): result = check_password_hash(self.password,raw_password) return result
(2)cmd终端重新添加用户
更改了字段之后要migrate和upgrade一下
python manage.py db migrate #创建迁移脚本 python manage.py db upgrade #生成到数据库
添加用户
python manage.py create_cms_user -u derek -p 123456 -e 1184405959@qq.com
可以看到现在密码是加密保存的了
