easyorm-py 1.0.8

easy_orm

example

1. Load db config

db_test = {
    "raw_sql": True,
    "mapper_xml_path": "test_xml",
    "default": {
        "db_type": "mysql",
        "host": "127.0.0.1",
        "port": 3306,
        "user": "root",
        "password": "123456",
        "database": "template",
    },
    "test": {
        "db_type": "mysql",
        "host": "127.0.0.1",
        "port": 3306,
        "user": "root",
        "password": "123456",
        "database": "template",
    }
}

from easy_orm import EasyOrmConfig, DBConfig
db_config = DBConfig(db_test)
EasyOrmConfig(db_config)

2. edit xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "">
<mapper namespace="TestMapper">

    <select id="find_data_by_ids">
        select id, username from test where id in
        <foreach collection="id_list" item="id" open="(" close=")" separator=",">
            #{id}
        </foreach>
    </select>

    <select id="test_page">
        select id, username from test
    </select>

    <select id="test_where" resultType="model.user.User">

        select id, username from test

        <where>
            <if test="params.get('id') is not None">
                id = #{id}
            </if>
        </where>

    </select>

    <insert id="add_data">
        insert into test (nickname, username) values ('xxx', 'xxx1')
    </insert>


    <update id="update_data_by_id">
        update test set nickname = #{nickname} where id = #{id}
    </update>


    <delete id="delete_data_by_id">
        delete from test where id = #{id}
    </delete>

</mapper>

3. Extend BaseMapper and Use

# TestMapper.py
from easy_orm import BaseMapper, Page, select_one, delete, datasource
from model.user import User

class TestMapper(BaseMapper):

    def find_data_by_ids(self, id_list: list): ...

    @select_one('select * from test where id = #{id}')
    def find_data_one(self, id: int): ...

    def test_page(self, page: Page): ...

    def test_where(self, id: int) -> list[User]: ...

    def add_data(self): ...

    def update_data_by_id(self, nickname: str, id: int): ...

    @delete('delete from test where id = #{id}')
    def delete_data_by_id2(self, id: int): ...

class TestService:

    @datasource("default", True)
    def test_find_user_one(self):
        TestMapper().find_data_one(1)
        self.test_find_user_one2()

    @datasource("test", True)
    def test_find_user_one2(self):
        TestMapper().find_data_one(1)

    
if __name__ == '__main__':
    
    test_service = TestService()
    test_service.test_find_user_one()
    
    test_mapper = TestMapper()
    test_mapper.find_data_by_ids([1, 2, 3])
