 # beego orm

-a powerful orm framework
+[![Build Status](https://drone.io/github.com/astaxie/beego/status.png)](https://drone.io/github.com/astaxie/beego/latest)
+
+A powerful orm framework for go.
+
+It is heavily influenced by Django ORM, SQLAlchemy.

 now, beta, unstable, may be changing some api make your app build failed.

@ -14,12 +18,25 @@ Passed all test, but need more feedback.

 **Features:**

-...
+* full go type support
+* easy for usage, simple CRUD operation
+* auto join with relation table
+* cross DataBase compatible query
+* Raw SQL query / mapper without orm model
+* full test keep stable and strong
+
+more features please read the docs

 **Install:**

 	go get github.com/astaxie/beego/orm

+## Changelog
+
+* 2013-08-13: update test for database types
+* 2013-08-13: go type support, such as int8, uint8, byte, rune
+* 2013-08-13: date / datetime timezone support very well
+
 ## Quick Start

 #### Simple Usage

+#### 时区设置
+
+orm 默认使用 time.Local 本地时区
+
+* 作用于 orm 自动创建的时间
+* 从数据库中取回的时间转换成 orm 本地时间
+
+如果需要的话，你也可以进行更改
+
+```go
+// 设置为 UTC 时间
+orm.DefaultTimeLoc = time.UTC
+```
+
+orm 在进行 RegisterDataBase 的同时，会获取数据库使用的时区，然后在 time.Time 类型存取的时做相应转换，以匹配时间系统，从而保证时间不会出错。
+
+**注意:** 鉴于 Sqlite3 的设计，存取默认都为 UTC 时间
+
+## RegisterModel
+
+如果使用 orm.QuerySeter 进行高级查询的话，这个是必须的。
+
+反之，如果只使用 Raw 查询和 map struct，是无需这一步的。您可以去查看 [Raw SQL 查询](Raw.md)
+
+将你定义的 Model 进行注册，最佳设计是有单独的 models.go 文件，在他的 init 函数中进行注册。
+
+
+迷你版 models.go
+```go
+package main
+
+import "github.com/astaxie/beego/orm"
+
+type User struct {
+	Id   int    `orm:"auto"`
+	name string
+}
+
+func init(){
+	orm.RegisterModel(new(User))
+}
+```
+
+RegisterModel 也可以同时注册多个 model
+
+```go
+orm.RegisterModel(new(User), new(Profile), new(Post))
+```

+QuerySeter 中用于描述字段和 sql 操作符，使用简单的 expr 查询方法

 字段组合的前后顺序依照表的关系，比如 User 表拥有 Profile 的外键，那么对 User 表查询对应的 Profile.Age 为条件，则使用 `Profile__Age` 注意，字段的分隔符号使用双下划线 `__`，除了描述字段， expr 的尾部可以增加操作符以执行对应的 sql 操作。比如 `Profile__Age__gt` 代表 Profile.Age > 18 的条件查询。
