Python build flask and orator framework development

First show my project directory structure:

The first step is to create a requirements.txt file

flask == 1.0.3 // Write version 
tzlocal == 1.5.1 
pillow == 6.1.0 
orator == 0.9.8 
validate-email == 1.3 
flask-paginate == 0.5.3 
gunicorn == 19.9.0 
pymysql == 0.9.3 The 

second step

pip install -r requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple 

Install the extension package needed above 

Step 3 Create the startup file run.py

from src import create_app 

app = create_app () 

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


here's create_app () self-created method mainly configures some files src __init__.py configuration file

# coding=utf-8

from flask import Flask, url_for, redirect
from src.config.setting import Config


def create_app():
    app = Flask(__name__)
    app.debug = True
    app.config.from_object(Config)

　　# app.add_template_global (lang, 'lang') // Add template global variables


    # Hook (middleware) 
    # @ app.before_request 
    # def before_request (): 
    # print (1) 

    # blueprint (module) 
    from src.module.bio import bp_bio 
    app.register_blueprint (bp_bio, url_prefix = "/ bio") 

    # index 
    app.route @ ( '/') 
    DEF system_index (): 
        return redirect (url_for ( "bio.index_index")) # declared here the root of url_for not need to write the name of the route need to write a method name 

    return App 


src the following main config below Write configuration file 
# Database configuration file 
class Config:

    # 密匙
    SECRET_KEY = '123'

    # 环境 development, production
    ENV = 'development'

    # 调试模式
    DEBUG = True

    # orator 数据库配置
    ORATOR_DATABASES = {
        'default': 'mysql',
        'mysql': {
            'driver': 'mysql',
            'host': '127.0.0.1',
            'database': 'member',
            'user': 'root',
            'password': '123123',
            'prefix': ''
        }
    }

    # 超级管理员
    SYS_SUPERS = [1]

　创建数据库配置 #模型层 都需要引入 这个数据库配置

from flask import current_app
from orator import DatabaseManager


class Database:

    @staticmethod
    def db():
        return DatabaseManager(current_app.config['ORATOR_DATABASES'])

模型层代码
先创建 base模型

from src.config.database import Database


class Base:
    db = None

    def __init__(self):
        self.db = Database.db()

之后每个模型类继承当前的base模型类
接下来一步 就是创建 服务层


from src.model.member import Member as MemberModel


class MemberService:

    @staticmethod
    def get_list():
        return MemberModel().get_member_list()

不需要任何处理 直接调用就好

接下来一步就是创建 控制器 这个 就是比较重要的一步
先在 bio下面的__init__.py注册 蓝图控制器

from flask import Blueprint

bp_bio = Blueprint("bio", __name__)

import src.module.bio.controller

在 src.moudle.bio.controller下面的__init__.py中 声明  你要 注册的 controller

import src.module.bio.controller.index #引入一下就可以了 
接下来 在 index.py写代码 就好了 也不需要创建class类

from flask import render_template
from src.service.member import MemberService

from src.module.bio import bp_bio


@bp_bio.route('/index', methods=['GET']) #声明路由
def index_index():
    member_list = MemberService().get_list()
    print(member_list)
    return render_template('bio/index.html')

大概就搭建结束  
接下来在命令行运行 python run.py文件即可
浏览器 访问 127.0.0.1:5000#默认端口 5000

所有代码运行成功
