pythink 0.0.5

simple CURD of mysql for python

pythink

灵感来自于ThinkPHP 部分代码实现参考了 records

根据现有业务 实现了简单的增删改查， 可以用作日常助手

依赖：

SQLAlchemy>=1.2.8

ps：原来基于peewee实现的，不过问题较多，就直接用SQLAlchemy

安装

pip install pythink

快速开始

新建表

CREATE TABLE `student` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `uid` int(11) DEFAULT NULL,
  `name` varchar(20) DEFAULT '',
  `age` int(11),
  `create_time` datetime DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB  DEFAULT CHARSET=utf8

代码示例

1、连接数据库，创建Model

# -*- coding: utf-8 -*-

from pythink import ThinkModel, ThinkDatabase

db_url = "mysql://root:123456@127.0.01:3306/demo"
db = ThinkDatabase(db_url)


class StudentThinkModel(ThinkModel):
    table_name = "student"
    database = db

2、插入操作

# 1、增加单条记录

data = {
    "name": "Tom"
}

>>> StudentThinkModel.insert(data)
>>> 1


# 2、增加多条记录
data = [
    {
        "name": "Tom",
    },
    {
        "name": "Jack"
    }
]

>>> StudentThinkModel.insert(data)
>>> 2



# 3、插入多条 分段插入
data = [
    {
        "name": "Tom",
        "age": 24,
    },
    {
        "name": "Tom",
        "age": 25,
    },
    {
        "name": "Tom",
        "age": 26,
    },
    {
        "name": "Tom",
        "age": 27,
    },
    {
        "name": "Tom",
        "age": 28,
    },
    {
        "name": "Tom",
        "age": 29,
    }
]

# 每次插入3 条数据
>>> StudentThinkModel.insert(data, truncate=3)
>>> 6

3、查询操作

# 1、查询数量
>>> StudentThinkModel.count()
>>> 24



# 2、查询记录
rows = StudentThinkModel.select(["name", "age"], where="id>25", limit=5)
for row in rows:
    print(row.name, row.age)


# ('Tom', 25L)
# ('Tom', 26L)
# ('Tom', 27L)
# ('Tom', 28L)
# ('Tom', 29L)

4、更新操作

# 条件更新
data = {
    "name": "tom",
    "age": 30
}

>>> StudentThinkModel.update(data, "id=25")
>>> 1

5、删除操作

# 删除
>>> StudentThinkModel.delete("id=13")
>>> 1
