+# beego orm
+
+[![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.
+
+**Support Database:**
+
+* MySQL: [github.com/go-sql-driver/mysql](https://github.com/go-sql-driver/mysql)
+* PostgreSQL: [github.com/lib/pq](https://github.com/lib/pq)
+* Sqlite3: [github.com/mattn/go-sqlite3](https://github.com/mattn/go-sqlite3)
+
+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
+
+* 2013-08-19: support table auto create
+* 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
+
+```go
+package main
+
+import (
+	"fmt"
+	"github.com/astaxie/beego/orm"
+	_ "github.com/go-sql-driver/mysql" // import your used driver
+)
+
+// Model Struct
+type User struct {
+	Id   int    `orm:"auto"`
+	Name string `orm:"size(100)"`
+}
+
+func init() {
+	// register model
+	orm.RegisterModel(new(User))
+
+	// set default database
+	orm.RegisterDataBase("default", "mysql", "root:root@/my_db?charset=utf8", 30)
+	
+	// create table
+	orm.RunSyncdb("default", false, true)	
+}
+
+func main() {
+	o := orm.NewOrm()
+
+	user := User{Name: "slene"}
+
+	// insert
+	id, err := o.Insert(&user)
+
+	// update
+	user.Name = "astaxie"
+	num, err := o.Update(&user)
+
+	// read one
+	u := User{Id: user.Id}
+	err = o.Read(&u)
+
+	// delete
+	num, err = o.Delete(&u)	
+}
+```
+
+#### Next with relation
+
+```go
+type Post struct {
+	Id    int    `orm:"auto"`
+	Title string `orm:"size(100)"`
+	User  *User  `orm:"rel(fk)"`
+}
+
+var posts []*Post
+qs := o.QueryTable("post")
+num, err := qs.Filter("User__Name", "slene").All(&posts)
+```
+
+#### Use Raw sql
+
+If you don't like ORM，use Raw SQL to query / mapping without ORM setting
+
+```go
+var maps []Params
+num, err := o.Raw("SELECT id FROM user WHERE name = ?", "slene").Values(&maps)
+if num > 0 {
+	fmt.Println(maps[0]["id"])
+}
+```
+
+#### Transaction
+
+```go
+o.Begin()
+...
+user := User{Name: "slene"}
+id, err := o.Insert(&user)
+if err == nil {
+	o.Commit()
+} else {
+	o.Rollback()
+}
+
+```
+
+#### Debug Log Queries
+
+In development env, you can simple use
+
+```go
+func main() {
+	orm.Debug = true
+...
+```
+
+enable log queries.
+
+output include all queries, such as exec / prepare / transaction.
+
+like this:
+
+```go
+[ORM] - 2013-08-09 13:18:16 - [Queries/default] - [    db.Exec /     0.4ms] - [INSERT INTO `user` (`name`) VALUES (?)] - `slene`
+...
+```
+
+note: not recommend use this in product env.

Although it borrows ideas from existing languages, it has unusual properties that make effective Go programs different in character from programs written in its relatives. A straightforward translation of a C++ or Java program into Go is unlikely to produce a satisfactory result—Java programs are written in Java, not Go. On the other hand, thinking about the problem from a Go perspective could produce a successful but quite different program. In other words, to write Go well, it's important to understand its properties and idioms. It's also important to know the established conventions for programming in Go, such as naming, formatting, program construction, and so on, so that programs you write will be easy for other Go programmers to understand.
+This document gives tips for writing clear, idiomatic Go code. It augments the language specification, the Tour of Go, and How to Write Go Code, all of which you should read first.`},
+		{User: users[1], Tags: []*Tag{tags[0], tags[1]}, Title: "Examples", Content: `The Go package sources are intended to serve not only as the core library but also as examples of how to use the language. Moreover, many of the packages contain working, self-contained executable examples you can run directly from the golang.org web site, such as this one (click on the word "Example" to open it up). If you have a question about how to approach a problem or how something might be implemented, the documentation, code and examples in the library can provide answers, ideas and background.`},
+		{User: users[1], Tags: []*Tag{tags[0], tags[2]}, Title: "Formatting", Content: `Formatting issues are the most contentious but the least consequential. People can adapt to different formatting styles but it's better if they don't have to, and less time is devoted to the topic if everyone adheres to the same style. The problem is how to approach this Utopia without a long prescriptive style guide.
+With Go we take an unusual approach and let the machine take care of most formatting issues. The gofmt program (also available as go fmt, which operates at the package level rather than source file level) reads a Go program and emits the source in a standard style of indentation and vertical alignment, retaining and if necessary reformatting comments. If you want to know how to handle some new layout situation, run gofmt; if the answer doesn't seem right, rearrange your program (or file a bug about gofmt), don't work around it.`},

+The program—and web server—godoc processes Go source files to extract documentation about the contents of the package. Comments that appear before top-level declarations, with no intervening newlines, are extracted along with the declaration to serve as explanatory text for the item. The nature and style of these comments determines the quality of the documentation godoc produces.`},

Although it borrows ideas from existing languages, it has unusual properties that make effective Go programs different in character from programs written in its relatives. A straightforward translation of a C++ or Java program into Go is unlikely to produce a satisfactory result—Java programs are written in Java, not Go. On the other hand, thinking about the problem from a Go perspective could produce a successful but quite different program. In other words, to write Go well, it's important to understand its properties and idioms. It's also important to know the established conventions for programming in Go, such as naming, formatting, program construction, and so on, so that programs you write will be easy for other Go programmers to understand.
-This document gives tips for writing clear, idiomatic Go code. It augments the language specification, the Tour of Go, and How to Write Go Code, all of which you should read first.`},
-		{User: users[1], Tags: []*Tag{tags[0], tags[1]}, Title: "Examples", Content: `The Go package sources are intended to serve not only as the core library but also as examples of how to use the language. Moreover, many of the packages contain working, self-contained executable examples you can run directly from the golang.org web site, such as this one (click on the word "Example" to open it up). If you have a question about how to approach a problem or how something might be implemented, the documentation, code and examples in the library can provide answers, ideas and background.`},
-		{User: users[1], Tags: []*Tag{tags[0], tags[2]}, Title: "Formatting", Content: `Formatting issues are the most contentious but the least consequential. People can adapt to different formatting styles but it's better if they don't have to, and less time is devoted to the topic if everyone adheres to the same style. The problem is how to approach this Utopia without a long prescriptive style guide.
-With Go we take an unusual approach and let the machine take care of most formatting issues. The gofmt program (also available as go fmt, which operates at the package level rather than source file level) reads a Go program and emits the source in a standard style of indentation and vertical alignment, retaining and if necessary reformatting comments. If you want to know how to handle some new layout situation, run gofmt; if the answer doesn't seem right, rearrange your program (or file a bug about gofmt), don't work around it.`},
-		{User: users[2], Tags: []*Tag{tags[3]}, Title: "Commentary", Content: `Go provides C-style /* */ block comments and C++-style // line comments. Line comments are the norm; block comments appear mostly as package comments, but are useful within an expression or to disable large swaths of code.
-The program—and web server—godoc processes Go source files to extract documentation about the contents of the package. Comments that appear before top-level declarations, with no intervening newlines, are extracted along with the declaration to serve as explanatory text for the item. The nature and style of these comments determines the quality of the documentation godoc produces.`},

+## cache
+cache is a Go cache manager. It can use many cache adapters. The repo is inspired by `database/sql` .
+
+
+## How to install?
+
+	go get github.com/astaxie/beego/cache
+
+
+## What adapters are supported?
+
+As of now this cache support memory, Memcache and Redis.
+
+
+## How to use it?
+
+First you must import it
+
+	import (
+		"github.com/astaxie/beego/cache"
+	)
+
+Then init a Cache (example with memory adapter)
+
+	bm, err := cache.NewCache("memory", `{"interval":60}`)	
+
+Use it like this:	
+	
+	bm.Put("astaxie", 1, 10 * time.Second)
+	bm.Get("astaxie")
+	bm.IsExist("astaxie")
+	bm.Delete("astaxie")

+
+## Memory adapter
+
+Configure memory adapter like this:
+
+	{"interval":60}
+
+interval means the gc time. The cache will check at each time interval, whether item has expired.
+
+
+## Memcache adapter
+
+Memcache adapter use the [gomemcache](http://github.com/bradfitz/gomemcache) client.
+
+Configure like this:
+
+	{"conn":"127.0.0.1:11211"}
+
+
+## Redis adapter
+
+Redis adapter use the [redigo](http://github.com/gomodule/redigo) client.
+
+Configure like this:
+
+	{"conn":":6039"}

+# httplib
+httplib is an libs help you to curl remote url.
+
+# How to use?
+
+## GET
+you can use Get to crawl data.
+
+	import "github.com/astaxie/beego/httplib"
+	
+	str, err := httplib.Get("http://beego.me/").String()
+	if err != nil {
+        	// error
+	}
+	fmt.Println(str)
+	
+## POST
+POST data to remote url
+
+	req := httplib.Post("http://beego.me/")
+	req.Param("username","astaxie")
+	req.Param("password","123456")
+	str, err := req.String()
+	if err != nil {
+        	// error
+	}
+	fmt.Println(str)
+
+## Set timeout
+
+The default timeout is `60` seconds, function prototype:
+
+	SetTimeout(connectTimeout, readWriteTimeout time.Duration)
+
+Example:
+
+	// GET
+	httplib.Get("http://beego.me/").SetTimeout(100 * time.Second, 30 * time.Second)
+	
+	// POST
+	httplib.Post("http://beego.me/").SetTimeout(100 * time.Second, 30 * time.Second)
+
+
+## Debug
+
+If you want to debug the request info, set the debug on
+
+	httplib.Get("http://beego.me/").Debug(true)
+	
+## Set HTTP Basic Auth
+
+	str, err := Get("http://beego.me/").SetBasicAuth("user", "passwd").String()
+	if err != nil {
+        	// error
+	}
+	fmt.Println(str)
+	
+## Set HTTPS
+
+If request url is https, You can set the client support TSL:
+
+	httplib.SetTLSClientConfig(&tls.Config{InsecureSkipVerify: true})
+	
+More info about the `tls.Config` please visit http://golang.org/pkg/crypto/tls/#Config	
+
+## Set HTTP Version
+
+some servers need to specify the protocol version of HTTP
+
+	httplib.Get("http://beego.me/").SetProtocolVersion("HTTP/1.1")
+	
+## Set Cookie
+
+some http request need setcookie. So set it like this:
+
+	cookie := &http.Cookie{}
+	cookie.Name = "username"
+	cookie.Value  = "astaxie"
+	httplib.Get("http://beego.me/").SetCookie(cookie)
+
+## Upload file
+
+httplib support mutil file upload, use `req.PostFile()`
+
+	req := httplib.Post("http://beego.me/")
+	req.Param("username","astaxie")
+	req.PostFile("uploadfile1", "httplib.pdf")
+	str, err := req.String()
+	if err != nil {
+        	// error
+	}
+	fmt.Println(str)
+
+

+## logs
+logs is a Go logs manager. It can use many logs adapters. The repo is inspired by `database/sql` .
+
+
+## How to install?
+
+	go get github.com/astaxie/beego/logs
+
+
+## What adapters are supported?
+
+As of now this logs support console, file,smtp and conn.
+
+
+## How to use it?
+
+First you must import it
+
+```golang
+import (
+	"github.com/astaxie/beego/logs"
+)
+```
+
+Then init a Log (example with console adapter)
+
+```golang
+log := logs.NewLogger(10000)
+log.SetLogger("console", "")
+```
+
+> the first params stand for how many channel
+
+Use it like this:
+
+```golang
+log.Trace("trace")
+log.Info("info")
+log.Warn("warning")
+log.Debug("debug")
+log.Critical("critical")
+```
+
+## File adapter
+
+Configure file adapter like this:
+
+```golang
+log := NewLogger(10000)
+log.SetLogger("file", `{"filename":"test.log"}`)
+```
+
+## Conn adapter
+
+Configure like this:
+
+```golang
+log := NewLogger(1000)
+log.SetLogger("conn", `{"net":"tcp","addr":":7020"}`)
+log.Info("info")
+```
+
+## Smtp adapter
+
+Configure like this:
+
+```golang
+log := NewLogger(10000)
+log.SetLogger("smtp", `{"username":"beegotest@gmail.com","password":"xxxxxxxx","host":"smtp.gmail.com:587","sendTos":["xiemengjun@gmail.com"]}`)
+log.Critical("sendmail critical")
+time.Sleep(time.Second * 30)
+```
