db config 目前只支持mysql,欢迎提交其他数据库的实现 db.database = example db.raise_on_warnings = True db.charset = utf8mb4 db.show_sql = True ; profiles config for env [local] db.user = root db.password = db.host = 127.0.0.1 db.port = 3306 ``` 4、简单实用的日志工具 ```python # 配置 config.ini log.path = /opt/logs/pesto-orm/pesto-orm.log log.level = INFO # 使用简单 logger = LoggerFactory.get_logger('dialect.mysql.domain') logger.info('打印日志') ``` 5、支持数据库事务 ```python #一个注解告别,python下的事务烦恼 @transaction() def methodX(): pass ``` 6、环境隔离的参数配置工具 config.ini, 公共参数放default,定制参数放在各自的环境 ```python [default] a=x [dev] [test] [prod] #取值 #Configer.get('param_name') ``` run with env(default is local, dev, test, prod) ```bash env=$ENV python ./xx/main.py >> std_out.log 2>&1 ``` 7、等等 2、结构 --- 领域对象:领域模型对应的属性和行为 仓库:批量操作领域对象,或者特殊的一些数据操作逻辑 领域服务:统筹领域模型的行为,或者更复杂的单个模型无法完成的行为 只需要配置数据库相关的参数,通过领域模型,或者仓库即可操作数据,简单易用,业务逻辑复杂可以加入领域服务概念 3、示例 --- pesto-example(flask + pesto-orm) build in python 3.7 add dependencies in requirements.txt(重要,必须要有,好好管理依赖才能利于项目长期配合,放在项目root目录): ```text pesto-orm==0.0.7 mysql-connector-python==8.0.11 Flask==1.0.2 ``` add config in config.ini(重要,如果要使用配置,日志等依赖配置的组件,此文件需和requirements.txt同级目录): ```ini [DEFAULT] app.key = $root_project log.path = $root_path/pesto-orm.log log.level = INFO ; db config 目前只支持mysql,欢迎提交其他数据库的实现 db.database = example db.raise_on_warnings = True db.charset = utf8mb4 db.show_sql = True ; profiles config for env [local] db.user = root db.password = db.host = 127.0.0.1 db.port = 3306 [dev] [test] [prod] ``` run with env(default is local, dev, test, prod) ```bash env=$ENV python ./pesto_example/main.py >> std_out.log 2>&1 ``` main 示例example,可以直接执行main方法启动(需先执行数据库的创建,以及配置数据的相关信息) make `pesto_example` as SourcesRoot 创建数据库 ```sql create database example; use example; create table example( id INT UNSIGNED AUTO_INCREMENT, title VARCHAR(255) NOT NULL, created_at DATETIME NOT NULL, updated_at DATETIME NOT NULL, deleted_at DATETIME NULL, PRIMARY KEY(id) )ENGINE=InnoDB DEFAULT CHARSET=utf8mb4; ``` 启动入口 ```python @app.route('/') def index(): data = {'name': 'pesto-example'} return jsonify(data) if __name__ == '__main__': port = 8080 try: app.run(host='0.0.0.0', port=port) except (KeyboardInterrupt, SystemExit): print('') logger.info('Program exited.') except (Exception,): logger.error('Program exited. error info:\n') logger.error(traceback.format_exc()) sys.exit(0) ``` model 模型创建,只需要配置对应的表名和主键,领域模型的行为可以扩展到该类 ```python class Example(MysqlBaseModel): def __init__(self): super(Example, self).__init__(table_name='example', primary_key='id') ``` repository 依赖于模型,执行批量或者复杂的sql逻辑 ```python class ExampleRepository(MysqlBaseRepository): def __init__(self): super(ExampleRepository, self).__init__(Example) ``` router api的路由信息,数据操作方式 ```python app_example = Blueprint('example', __name__, url_prefix='/examples') example_repository = ExampleRepository() @app_example.route('', methods=['GET']) def examples(): # 条件查询 data = example_repository.query_by(where="") if len(data) <= 0: jsonify(error="not found any data"), 404 return jsonify(data) @app_example.route('/', methods=['GET']) def example(id): # 条件查询 data = example_repository.query_first_by(where="`id`= %s", params=(id,)) if data is None: jsonify(error="not found any data"), 404 return jsonify(data) @app_example.route('', methods=['POST']) def save(): data = request.get_json() if data is not None and len(data) > 0: example = Example() example.set_attrs(data) example.created_at = datetime.datetime.now() example.updated_at = datetime.datetime.now() # 保存数据 example.save() return jsonify(example.id) else: return jsonify(error="not found any data to save"), 400 @app_example.route('/', methods=['DELETE']) def delete(id): result = True example = Example() example.id = id example.deleted_at = datetime.datetime.now() # 根据id删除数据 example.delete() return jsonify(result) @app_example.route('/', methods=['PUT']) def update(id): result = True data = request.get_json() example = Example() example.set_attrs(data) example.id = id example.updated_at = datetime.datetime.now() # 根据id更新数据 example.update() return jsonify(result) ``` 4、测试 --- ```bash # 查询全部数据 curl -X GET \ http://localhost:8080/examples # 添加一条数据 curl -X POST \ http://localhost:8080/examples \ -H 'content-type: application/json' \ -d '{ "title":"第三个测试" }' # 根据id查询 curl -X GET \ http://localhost:8080/examples/1 # 根据id 更新数据 curl -X PUT \ http://localhost:8080/examples/1 \ -H 'content-type: application/json' \ -d '{ "title":"这是第一个已改测试" }' # 根据id删除数据 curl -X DELETE \ http://localhost:8080/examples/3 ``` 上传pypi包 ```python pip install twine python setup.py sdist bdist_wheel twine upload --repository-url https://upload.pypi.org/legacy/ dist/* ```
