getAllNamedRoles returning null

[lucaslrolim]

I have implemented these two methods:

    async getAllUserRoles(){
        let roles = this.enforcer.getAllNamedRoles('g');
        return roles;
    }

    async getAllResourceRoles(){
        let roles = this.enforcer.getAllNamedRoles('g2');
        return roles;
    }

And some of my policies are:

g, test_role, admin
g, sub_role_test1, test_role
g, sub_role_test2, test_role
g, sub_role_test2, test_role
g, test_role_2, admin
g, user_test, just_test_role
g2, glosas, plataforma
g2, credentials, plataforma

In both methods the result is null. Is this a bug?

Can you provide model conf.

@lucaslrolim We have added some tests here: 43e2654 . And it shows e.getAllRoles() works. Can you try this test and see if there's anything wrong with your code.

My model is:

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

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

[role_definition]
g = _, _
g2 = _, _

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

[matchers]
m = g(r.sub, p.sub) && g2(r.obj, p.obj) && (regexMatch(r.dom, p.dom) || r.dom ===  '') && (regexMatch(r.act, p.act) || p.act ===  'all')

@hsluoyz I'm using getAllNamedRoles, maybe this method has differences of getAllRoles. I will double check my code.

dev env

node: v8.11.2
casbin: v1.1.9

simple test

async function test() {
  const modelText = `
[request_definition]
r = sub, obj, dom, act

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

[role_definition]
g = _, _
g2 = _, _

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

[matchers]
m = g(r.sub, p.sub) && g2(r.obj, p.obj) && (regexMatch(r.dom, p.dom) || r.dom ===  '') && (regexMatch(r.act, p.act) || p.act ===  'all')
`;
  const m = newModel(modelText);
  const e = await newEnforcer(m);
  await e.addNamedGroupingPolicy('g', 'test_role', 'admin');
  await e.addNamedGroupingPolicy('g', 'sub_role_test1', 'test_role');
  await e.addNamedGroupingPolicy('g', 'sub_role_test2', 'test_role');
  await e.addNamedGroupingPolicy('g', 'sub_role_test2', 'test_role');
  await e.addNamedGroupingPolicy('g', 'test_role_2', 'admin');
  await e.addNamedGroupingPolicy('g', 'user_test', 'just_test_role');
  await e.addNamedGroupingPolicy('g2', 'glosas', 'plataforma');
  await e.addNamedGroupingPolicy('g2', 'credentials', 'plataforma');
  const g = e.getAllNamedRoles('g');
  console.log(g, g.length !== 0 && g.some(n => n === 'admin'));
  const g2 = e.getAllNamedRoles('g2');
  console.log(g2, g2.length !== 0 && g2.some(n => n === 'plataforma'));
}

print result

[ 'admin', 'test_role', 'just_test_role' ] true
[ 'plataforma' ] true

You can try using the above test :)

@lucaslrolim getAllRoles() calls getAllNamedRoles() internally, so it proves this function works for at least for the example.

The error was really related to the order of my Express routes. Sorry about the mistake e thank you for the help @hsluoyz and @nodece.
