[Question] GetRolesForUserInDomain can not obtain data after using AddNamedDomainLinkConditionFunc

[301lj]

What's your scenario? What do you want to achieve?
I want to use GetRolesForUserInDomain to obtain roles that the user have

Your model:

[request_definition]
r = sub, dom, obj, act

[policy_definition]
p = sub, dom, obj, act

[role_definition]
g = _, _, _, (_, _)

[policy_effect]
e = some(where (p.eft == allow))

[matchers]
m = g(r.sub, p.sub, r.dom) && r.dom == p.dom && r.obj == p.obj && \
(keyMatch(r.act, p.act) || keyMatch2(r.act, p.act) || keyMatch3(r.act, p.act) || keyMatch4(r.act, p.act) || keyMatch5(r.act, p.act) || globMatch(r.act, p.act))

Your policy:

p, test1, domain1, service1, /list
p, test1, domain1, service1, /get/:id/*
p, test1, domain1, service1, /add
p, test1, domain1, service1, /user/*
p, admin, domain1, service1, /*
p, qa1, domain2, service2, /broadcast
p, qa1, domain2, service2, /trip
p, qa1, domain2, service2, /notify
p, qa1, domain2, service2, /dynamic-sql

g, alice, test1, domain1, _, 2023-12-30 00:00:00
g, bob, qa1, domain2, _, 2023-12-30 00:00:00

codes:

package main

import (
	"github.com/casbin/casbin/v2"
	"github.com/casbin/casbin/v2/model"
	fileAdapter "github.com/casbin/casbin/v2/persist/file-adapter"
	"github.com/casbin/casbin/v2/util"
	"log"
)

func main() {

	m, _ := model.NewModelFromFile("model5.conf")
	a := fileAdapter.NewAdapter("policy5.csv")
	e, _ := casbin.NewEnforcer(m, a)

	g := e.GetNamedGroupingPolicy("g")
	for _, gp := range g {
		e.AddNamedDomainLinkConditionFunc("g", gp[0], gp[1], gp[2], util.TimeMatchFunc)
	}
	check5(e, []interface{}{"alice", "domain1", "service1", "/add"})
	check5(e, []interface{}{"alice", "domain1", "service1", "/list"})
	check5(e, []interface{}{"alice", "domain1", "service1", "/userEdit"})
	check5(e, []interface{}{"alice", "domain1", "service1", "/get/9527/info"})

	log.Println("-------")

	/**
	here, the error will occer
	*/
	rolesForUserInDomain := e.GetRolesForUserInDomain("alice", "domain1")
	for i := range rolesForUserInDomain {
		role := rolesForUserInDomain[i]
		permissionsForUser := e.GetPermissionsForUser(role)
		for j := range permissionsForUser {
			log.Println(permissionsForUser[j])
		}
	}
	log.Println("--------------")
}

func check5(e *casbin.Enforcer, slice1 []interface{}) {
	result1, error := e.Enforce(slice1...)
	if error != nil {
		log.Println(error)
	}
	log.Println(result1)
}

Your request(s):

I want to use GetRolesForUserInDomain to obtain roles that the user have, but a error occurred.
I found that if I not use this method AddNamedDomainLinkConditionFunc, there is no problem.
I want to know how to solve this? think you!

Almost all the methods can not be used, except GetAllNamedRoles
