Project Description

JohnnieRunner is SQLAlchemy Wrapper for Active Record pattern O/R Mapper

Dependencies

  • Python2.7 or Later
  • SQLAlchemy >= 1.0.8
  • MySQL-Python >= 1.2.5

Support RDBMS

  • MySQL

Goal

  • Add Rails like ActiveRecord Api
  • Database Migration
  • All Supports of SQLAlchemy RDBMS

Usage

Prepare

  1. generate testing database

    $ mysql -u root -p
    mysql> create database johnnie;
    Query OK, 1 row affected (0.01 sec)
    
    mysql> exit;
    Bye
    
  2. define O/R Mapper structure

    from johnnie import AbstractModel, create_session
    from johnnie.types import Column, String, Integer
    
    session = create_session('localhost', 'root', 'root user password', 'johnnie')
    
    
    class Repositories(AbstractModel):
        class Meta:
            session = session
    
        id = Column('id', Integer(unsigned=True), primary_key=True)
        name = Column('name', String(255), nullable=False)
        author = Column('author', String(255), nullable=False)
        url = Column('url', String(255), nullable=False)
    
  3. create model table

    $ python
    >>> from hoge import Repositories
    >>> Repositories.metadata.create_all(Repositories.get_session_engine())
    >>> exit()
    

Example

  1. create entity

    >>> from hoge import Repositories
    >>> entity = Repositories(name="JohnnieRunner", author="teitei-tk", url="https://github.com/teitei-tk/JohnnieRunner")
    
    or
    
    >>> entity_data = {"name": "JohnnieRunner", "author": "teitei-tk", "url": "https://github.com/teitei-tk/JohnnieRunner"}
    >>> entity = Repositories.new(entity_data)
    
  2. create record

    >>> entity.save()
    True
    
    mysql> select * from repositories;
    +----+---------------+-----------+--------------------------------------------+
    | id | name          | author    | url                                        |
    +----+---------------+-----------+--------------------------------------------+
    |  1 | JohnnieRunner | teitei-tk | https://github.com/teitei-tk/JohnnieRunner |
    +----+---------------+-----------+--------------------------------------------+
    1 row in set (0.00 sec)
    mysql>
    
  3. read record

    >>> entity = Repositories.get(1)
    
    or
    
    >>> entity = Repositories.find(1)
    
    >>> entity.name
    u"JohnnieRunner"
    >>> entity.author
    u"teitei-tk"
    >>> entity.url
    u"https://github.com/teitei-tk/JohnnieRunner"
    
  4. update record

    >>> entity.name = u"update_test"
    >>> entity.save()
    True
    
    mysql> select * from repositories;
    +----+-------------+-----------+--------------------------------------------+
    | id | name        | author    | url                                        |
    +----+-------------+-----------+--------------------------------------------+
    |  1 | update_test | teitei-tk | https://github.com/teitei-tk/JohnnieRunner |
    +----+-------------+-----------+--------------------------------------------+
    mysql>
    
  5. delete record

    >>> entity.delete()
    True
    
    mysql> select * from repositories;
    Empty set (0.00 sec)
