policy get loaded twice

[pot-code]

constructor function:

func NewCasbinEnforcer(db *gorm.DB) *casbin.Enforcer {
    gormadapter.TurnOffAutoMigrate(db)
    a, err := gormadapter.NewAdapterByDBWithCustomTable(db, &model.CasbinRule{}, "casbin_rules")
    if err != nil {
        panic(fmt.Errorf("error creating casbin gorm adapter: %w", err))
    }

    e, err := casbin.NewEnforcer("casbin/model.conf", a)
    if err != nil {
        panic(fmt.Errorf("error creating casbin enforcer: %w", err))
    }
    e.SetRoleManager(newRoleManager(db))
    e.EnableAutoSave(true)
    e.LoadPolicy()
    return e
}

logs(zerolog adapted):

7:36PM TRC elapsed=2.047459 rows=1 sql="SELECT * FROM `casbin_rules` ORDER BY ID"
7:36PM TRC elapsed=0.93575 rows=1 sql="SELECT * FROM `casbin_rules` ORDER BY ID"

if I delete e.LoadPolicy(), the sql will only print once

In casbin.NewEnforcer() contains an automatic LoadPolicy.

The order of calls is as follows, which you can see using the IDE's debugger

1. func NewEnforcer(params ...interface{}) (*Enforcer, error)
2. e.InitWithAdapter(p0, p1.(persist.Adapter))
3. e.InitWithModelAndAdapter(m, adapter)
4. e.LoadPolicy()
5. e.adapter.LoadPolicy(newModel)

@pot-code use enforcer, _ := casbin.NewEnforcer() to create an enforcer without implicit LoadPolicy() call, see example at: https://casbin.org/docs/policy-subset-loading
