Installation

go get github.com/casbin/gorm-adapter

Simple Example

package main

import (
	"github.com/casbin/casbin"
	"github.com/casbin/gorm-adapter"
	_ "github.com/go-sql-driver/mysql"
)

func main() {
	// Initialize a Gorm adapter and use it in a Casbin enforcer:
	// The adapter will use the MySQL database named "casbin".
	// If it doesn't exist, the adapter will create it automatically.
	// You can also use a already existing gorm instance with gormadapter.NewAdapterByDB(gormInstance)
	a := gormadapter.NewAdapter("mysql", "mysql_username:mysql_password@tcp(127.0.0.1:3306)/") // Your driver and data source. 
	e := casbin.NewEnforcer("examples/rbac_model.conf", a)
	
	// Or you can use an existing DB "abc" like this:
    // The adapter will use the table named "casbin_rule".
    // If it doesn't exist, the adapter will create it automatically.
    // a := gormadapter.NewAdapter("mysql", "mysql_username:mysql_password@tcp(127.0.0.1:3306)/abc", true)

	// Load the policy from DB.
	e.LoadPolicy()
	
	// Check the permission.
	e.Enforce("alice", "data1", "read")
	
	// Modify the policy.
	// e.AddPolicy(...)
	// e.RemovePolicy(...)
	
	// Save the policy back to DB.
	e.SavePolicy()
}
