Bbolt Adapter

BBolt Adapter is the BboltDB adapter for Casbin. With this library, Casbin can load a policy from a previously opened BoltDB or save the policy to it.

Installation

go get github.com/morris-kelly/bbolt-adapter

Simple Example

package main

import (
"flag"
   "log"

   "go.etcd.io/bbolt"
   "github.com/casbin/casbin"
   "github.com/casbin/casbin/persist"
   "github.com/morris-kelly/bolt-adapter"
)

var populate bool

func init() {
    flag.BoolVar(&populate, "populate", false, "populate the db from a file first")
}

func main() {
    flag.Parse()

    // Initialize a bolt DB adapter and use it in a Casbin enforcer:
    db, err := bolt.Open("db.dat", 0600, nil)
    if err != nil {
        log.Fatalf("error opening db: %s\n", err)
    }
    defer db.Close()

    adapter := boltadapter.NewAdapter(db) // Pass in the already open bolt DB.

    if populate {
        populateDB(adapter)
    }

    e := casbin.NewEnforcer("examples/rbac_model.conf", adapter)

    // Load the policy from DB.
    e.LoadPolicy()

    // Check the permission.
    e.Enforce("alice", "data1", "read")

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

// populateDB loads a policy from file and saves it to the DB
func populateDB(adapter persist.Adapter) {
    e := casbin.NewEnforcer("examples/rbac_model.conf", "examples/rbac_policy.csv")
    adapter.SavePolicy(e.GetModel())
}
