Simple Postgres Example

package main

import (
	pgadapter "github.com/MonedaCacao/casbin-pg-adapter"
	"github.com/casbin/casbin"
)

func main() {
	// Initialize a Go-pg adapter and use it in a Casbin enforcer:
	// The adapter will use the Postgres database named "casbin".
	// If it doesn't exist, the adapter will create it automatically.
	a, _ := pgadapter.NewAdapter() // Your driver and data source.

	// 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.

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

	// 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()
}
