Gorm Adapter Ex

This gorm-adapter-ex is an extended version ofGorm-Adapter.It introduces great and implementsproposal of customizability by reflection. The database structure can be arbitrary as long as it has{"ID", "Ptype", "V0"} three fields.

About Gorm Adapter

Gorm Adapter is theGorm adapter forCasbin. With this library, Casbin can load policy from Gorm supported database or save policy to it.

Based onOfficially Supported Databases, The current supported databases are:

MySQL
PostgreSQL
SQL Server
Sqlite3

gorm-adapter usegithub.com/glebarez/sqlite instead of gorm official sqlite drivergorm.io/driver/sqlite because the latter needscgo support. But there is almost no difference between the two driver. If there is a difference in use, please submit an issue.

other 3rd-party supported DBs in Gorm website or other places.

Installation

go get github.com/casbin/gorm-adapter/v3

Simple Example

package mainimport ("github.com/casbin/casbin/v2"gormadapter"github.com/casbin/gorm-adapter/v3"_"github.com/go-sql-driver/mysql")funcmain() {// Initialize a Gorm 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.// You can also use an already existing gorm instance with gormadapter.NewAdapterByDB(gormInstance)a,_:=gormadapter.NewAdapter("mysql","mysql_username:mysql_password@tcp(127.0.0.1:3306)/")// Your driver and data source.e,_:=casbin.NewEnforcer("examples/rbac_model.conf",a)// 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 := gormadapter.NewAdapter("mysql", "mysql_username:mysql_password@tcp(127.0.0.1:3306)/abc", true)// 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()}

Turn off AutoMigrate

New an adapter will useAutoMigrate by default for create table, if you want to turn it off, please use APITurnOffAutoMigrate(db *gorm.DB) *gorm.DB. See example:

db,err:=gorm.Open(mysql.Open("root:@tcp(127.0.0.1:3306)/casbin"),&gorm.Config{})TurnOffAutoMigrate(db)// a,_ := NewAdapterByDB(...)// a,_ := NewAdapterByDBUseTableName(...)a,_:=NewAdapterByDBWithCustomTable(...)

Find out more details atgorm-adapter#162

Customize table columns example

You can change the gorm struct tags, but the table structure must stay the same.

package mainimport ("github.com/casbin/casbin/v2"gormadapter"github.com/casbin/gorm-adapter/v3""gorm.io/gorm")funcmain() {// Increase the column size to 512.typeCasbinRulestruct {IDuint`gorm:"primaryKey;autoIncrement"`Ptypestring`gorm:"size:512;uniqueIndex:unique_index"`V0string`gorm:"size:512;uniqueIndex:unique_index"`V1string`gorm:"size:512;uniqueIndex:unique_index"`V2string`gorm:"size:512;uniqueIndex:unique_index"`V3string`gorm:"size:512;uniqueIndex:unique_index"`V4string`gorm:"size:512;uniqueIndex:unique_index"`V5string`gorm:"size:512;uniqueIndex:unique_index"`}db,_:= gorm.Open(...)// Initialize a Gorm adapter and use it in a Casbin enforcer:// The adapter will use an existing gorm.DB instnace.a,_:=gormadapter.NewAdapterByDBWithCustomTable(db,&CasbinRule{})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()}
