1.新建目录结构

2.在蓝图模块admin下__init__.py加入以下(home同理)

from flask import Blueprintadmin = Blueprint('admin', __name__)from . import views

3.在蓝图模块admin下views.py加入以下..测试(home同理)

from . import admin@admin.route('/')def index():    return '测试2............', 200

4.在app下的__init__.py中加入

from flask import Flaskfrom flask_sqlalchemy import SQLAlchemydb = SQLAlchemy()# ...def create_app():    app = Flask(__name__)    # 导入配置文件    app.config.from_object('app.settings')    # ...    # 初始化数据库    db.init_app(app)    # ...    # 注册蓝图(最后一步)    register(app)    return appdef register(app):    from .admin import admin    from .home import home    app.register_blueprint(admin, url_prefix='/admin')    app.register_blueprint(home)

5.在app下的settings配置文件加入

SQLALCHEMY_TRACK_MODIFICATIONS = TrueSQLALCHEMY_DATABASE_URI = 'mysql+pymysql://root:123456@127.0.0.1/xxx'

6.在app下的models.py加入

from datetime import datetimefrom app import dbclass People(db.Models):    pass

7.在总目录下的执行文件manage.py下加入

from flask_script import Managerfrom flask_migrate import Migrate, MigrateCommandfrom app import create_app# 此刻导入models.py下的db (app/__init__.py  ----> app/models.py -----> manage.py)from app.models import db# 创建app对象app = create_app()# 数据库迁移配置manager = Manager(app)migrate = Migrate(app, db)manager.add_command('db', MigrateCommand)if __name__ == "__main__":    manager.run()

8.models中表过多问题

1.新建app/models文件夹, 在其中的__init__.py 中加入db = SQLALchemy()2.在app/models/admin.py和app/models/home.py 下 分别引入 from . import db3.在app/__init__.py下引入from app.models import admin和from app.models import home和from app.models import db**********************以后加入一个文件就引入一次*******************4.   ... db.init(app) ...

9.执行命令

# 数据库迁移python manage.py db initpython manage.py db migratepython manage.py db upgrade运行python manage.py runserver
