• CURD
• Chainable API
• Embedded structs support
• Before/After Create/Save/Update/Delete Callbacks

• Automatically CreatedAt, UpdatedAt
• Soft Delete
• Create/Drop table from struct
• Dynamically set table name when search, create, update, delete...
• Prevent SQL Injection
• Goroutines friendly
• Database Pool
• Convention Over Configuration

import "github.com/jinzhu/gorm"
import _ "github.com/lib/pq"
// import _ "github.com/go-sql-driver/mysql"
// import _ "github.com/mattn/go-sqlite3"

db, err := Open("postgres", "user=gorm dbname=gorm sslmode=disable")
// db, err = Open("mysql", "gorm:gorm@/gorm?charset=utf8&parseTime=True")
// db, err = Open("sqlite3", "/tmp/gorm.db")


// Set the maximum idle database connections
db.SetPool(100)


// Gorm is goroutines friendly, so you can create a global variable to keep the connection and use it everywhere like this

var DB gorm.DB

func init() {
    DB, err = gorm.Open("postgres", "user=gorm dbname=gorm sslmode=disable")
    if err != nil {
        panic(fmt.Sprintf("Got error when connect database, the error is '%v'", err))
    }
}
