项目设计

一,模块设计 home:

admin:

二,目录设计

manage.py --- 入口文件 app/ --- 项目目录 ├── init.py --- 初始化文件 ├── models.py --- 数据模型文件 ├── admin/ --- 后台应用 │ ├── init.py │ └── views.py ├── home/ --- 前台应用 │ ├── init.py │ └── views.py ├── static/ --- 静态文件目录 └── templates/ --- 模板目录 ├── admin/ └── home/ |manage.py ---入口文件

三,使用蓝图构建项目应用结构

app初始化

app/__init__.py:

from flask import Flask

app = Flask(__name__)
app.debug = True

from app.home import home as home_blueprint
from app.admin import admin as admin_blueprint

app.register_blueprint(home_blueprint)
app.register_blueprint(admin_blueprint,url_prefix="/admin")

admin模块应用

app/admin/__init__.py

from flask import Blueprint

admin = Blueprint("admin",__name__)

import app.admin.views

admin视图

app/admin/views.py:

from . import admin

@admin.route("/")
def index():
    return "<h1 style='color:red'>this is admin</h1>"

home模板应用

app/home/__init__.py

from flask import Blueprint

home= Blueprint("home",__name__)

import app.home.views

home视图

app/home/views.py:

from . import home

@home.route("/")
def index():
    return "<h1 style='color:green'>this is home</h1>"

入口文件

manage.py:

from app import app

if __name__ == "__main__":
    app.run()

运行项目:

数据模型设计

1,安装数据库连接依赖包 SQLAlchemy

sudo pip3 install flask-sqlalchemy

2,定义mysql数据库连接

from flask import Flask
from flask sqlalchemy import SQLAlchemy

app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = "mysql+pymysql://root:123456@localhost/blog"
app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = True

db = SQLAlchemy(app)


#会员数据模型
class User(db.Model)
    __tablename__ = 'user'
    id = db.Column(db.Integer,primary_key=True)
    name = db.Column(db.String(100),unique=True)
    pwd= db.Column(db.String(100))
    email= db.Column(db.String(100))
    phone= db.Column(db.String(11),unique=True)
    info= db.Column(db.Text)
    face = db.Column(db.String(255))
    addtime = db.Column(db.DateTime,index=True,default=datetime.utcnow)

# if __name__=='__main__':
#     db.create_all()

3.models.py
