Beego ORM Adapter

Beego ORM Adapter is the Beego ORM adapter for Casbin. With this library, Casbin can load policy from Beego ORM supported database or save policy to it.

Based on Beego ORM Support, The current supported databases are:

• MySQL: github.com/go-sql-driver/mysql
• PostgreSQL: github.com/lib/pq
• Sqlite3: github.com/mattn/go-sqlite3

Installation

go get github.com/casbin/beego-orm-adapter/v2

Simple Example

package main

import (
    "log"

    beegoormadapter "github.com/casbin/beego-orm-adapter/v2"
    "github.com/casbin/casbin/v2"
    _ "github.com/go-sql-driver/mysql"
)

func main() {
    // Initialize a Beego ORM adapter and use it in a Casbin enforcer:
    a, err := beegoormadapter.NewAdapter("default", "mysql", "mysql_username:mysql_password@tcp(127.0.0.1:3306)/dbname") // Your driver and data source. 
    if err != nil {
        log.Fatalln(err)
    }

    e, err := casbin.NewEnforcer("examples/rbac_model.conf", a)
    if err != nil {
        log.Fatalln(err)
    }
    // Check the permission.
    e.Enforce("alice", "data1", "read")

    // Modify the policy.
    // e.AddPolicy(...)
    // e.RemovePolicy(...)

    // Save the policy back to DB.
    e.SavePolicy()
