Beego ORM Adapter Build Status Coverage Status Godoc

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:

Installation

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

Simple MySQL Example

package main

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

func main() {
	// Initialize a Beego ORM 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.
	a := beegoormadapter.NewAdapter("mysql", "mysql_username:mysql_password@tcp(127.0.0.1:3306)/") // 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.
	// a := beegoormadapter.NewAdapter("mysql", "mysql_username:mysql_password@tcp(127.0.0.1:3306)/abc", true)

	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()
}

Simple Postgres Example

package main

import (
	"github.com/casbin/beego-orm-adapter"
	"github.com/casbin/casbin"
	_ "github.com/lib/pq"
)

func main() {
	// Initialize a Beego ORM 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 := beegoormadapter.NewAdapter("postgres", "user=postgres_username password=postgres_password host=127.0.0.1 port=5432 sslmode=disable") // 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.
	// a := beegoormadapter.NewAdapter("postgres", "dbname=abc user=postgres_username password=postgres_password host=127.0.0.1 port=5432 sslmode=disable", true)

	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()
}

	// contains filtered or unexported fields
}

Adapter represents the Xorm adapter for policy storage.

func NewAdapter

func NewAdapter(driverName string, dataSourceName string, dbSpecified ...bool) *Adapter

NewAdapter is the constructor for Adapter. dbSpecified is an optional bool parameter. The default value is false. It's up to whether you have specified an existing DB in dataSourceName. If dbSpecified == true, you need to make sure the DB in dataSourceName exists. If dbSpecified == false, the adapter will automatically create a DB named "casbin".

func (*Adapter) AddPolicy

func (a *Adapter) AddPolicy(sec string, ptype string, rule []string) error

AddPolicy adds a policy rule to the storage.

func (*Adapter) LoadPolicy

func (a *Adapter) LoadPolicy(model model.Model) error

LoadPolicy loads policy from database.

func (*Adapter) RemoveFilteredPolicy

func (a *Adapter) RemoveFilteredPolicy(sec string, ptype string, fieldIndex int, fieldValues ...string) error

RemoveFilteredPolicy removes policy rules that match the filter from the storage.

func (*Adapter) RemovePolicy

func (a *Adapter) RemovePolicy(sec string, ptype string, rule []string) error

RemovePolicy removes a policy rule from the storage.

func (*Adapter) SavePolicy

func (a *Adapter) SavePolicy(model model.Model) error

SavePolicy saves policy to database.

type CasbinRule

type CasbinRule struct {
	Id    int
	PType string
	V0    string
	V1    string
	V2    string
	V3    string
