Ent Adapter is the ent adapter for Casbin. With this library, Casbin can load policy from PostgresSQL/Mysql or save policy to it.

Installation

go get github.com/casbin/ent-adapter

Usage

    a, err := NewAdapter("mysql", "root:@tcp(127.0.0.1:3306)/casbin")
    //a, err := NewAdapter("postgres", "user=postgres password=postgres host=127.0.0.1 port=5432 dbname=casbin")
    if err != nil {
        panic(err)	
    }
    e, err := casbin.NewEnforcer("/path/to/model",a)

Notification

The database used in adapter(like casbin) should be created manually before NewAdapter calling.
