1. 启动文件 - manage.py

from flask_script import Manager

from utils.app import create_app

# 创建app
app = create_app()

# 管理启动项目
manage = Manager(app=app)


if __name__ == '__main__':
    # 启动项目
    manage.run()

2. 创建app文件 - app.py

from flask import Flask

from app.setting import STATIC_DIR, TEMPLATES_DIR
from app.user_views import user_blue
from app.house_views import house_blue
from app.order_views import order_blue
from utils.config import Config
from utils.functions import init_ext


def create_app():
    # 初始化flask对象,指定static, templates文件夹路径,让项目运行时可以直接调用
    app = Flask(__name__,
                static_folder=STATIC_DIR,
                template_folder=TEMPLATES_DIR)

    # 配置
    app.config.from_object(Config)

    # 注册蓝图
    app.register_blueprint(blueprint=user_blue, url_prefix='/user')
    app.register_blueprint(blueprint=house_blue, url_prefix='/house')
    app.register_blueprint(blueprint=order_blue, url_prefix='/order')

    # 初始化(绑定)第三方库
    init_ext(app)

    return app

3. 配置文件 - config.py

from utils.functions import get_mysqldb_url, get_redisdb_url


class Config():
    # 配置数据库
    SQLALCHEMY_DATABASE_URI = get_mysqldb_url()
    SQLALCHEMY_TRACK_MODIFICATIONS = False

    # 配置session
    SESSION_TYPE = 'redis'
    SESSION_REDIS = get_redisdb_url()

4. 注册插件,绑定数据库方法的保存文件 - functions.py

import redis
from flask_session import Session

from app.models import db
from app.setting import MYSQL_DATABASES, REDIS_DATABASES


# 注册插件
def init_ext(app):

    # 绑定数据库和app
    db.init_app(app)

    # 绑定session 和app
    sess = Session()
    sess.init_app(app=app)

    return app


# 配置mysql数据库
def get_mysqldb_url():
    driver = MYSQL_DATABASES['DRIVER']
    dh = MYSQL_DATABASES['DH']
    root = MYSQL_DATABASES['ROOT']
    password = MYSQL_DATABASES['PASSWORD']
    host = MYSQL_DATABASES['HOST']
    port = MYSQL_DATABASES['PORT']
    name = MYSQL_DATABASES['NAME']
    return '{}+{}://{}:{}@{}:{}/{}'.format(driver, dh, root, password, host, port, name)


# 配置REDIS数据库
def get_redisdb_url():
    host = REDIS_DATABASES['HOST']
    port = REDIS_DATABASES['PORT']
    return redis.Redis(host=host, port=port)

5. 路径,数据库基础设置文件 - setting.py

import os

# 基础路径(项目)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
# template 路径
TEMPLATES_DIR = os.path.join(BASE_DIR, 'templates')
# static 路径
STATIC_DIR = os.path.join(BASE_DIR, 'static')
# meida 路径
MEDIA_DIR = os.path.join(STATIC_DIR, 'media')
# 保存图片的路径
UPLOAD_DIR = os.path.join(MEDIA_DIR, 'upload')
# 保存房屋图片的路径
HOUSE_DIR = os.path.join(UPLOAD_DIR, 'house')

# ========数据库配置
MYSQL_DATABASES = {
    'DRIVER': 'mysql',
    'DH': 'pymysql',
    'ROOT': 'root',
    'PASSWORD': '123456',
    'HOST': '127.0.0.1',
    'PORT': 3306,
    'NAME': 'ajzf'
}


REDIS_DATABASES = {
    'HOST': '127.0.0.1',
    'PORT': '6379'
}

6. 文件关联关系示意

注意: 各文件引入其它文件内容需导入, 调用Flask或者第三方库,也需导入
