V13 - Get member and roles without hitting databas...

I'm building a site that uses membership quite heavily. We have a lot of calls to check if a member is in a particular role, and am using this sort of code to do it:

Copy code

public bool IsEngineer(string objectIdentifier)
{
    var member = _memberService.GetByUsername(objectIdentifier);
    if (member != null)
    {
        return _memberService.GetAllRoles(objectIdentifier).Any(r => r.Equals(Constants.MemberGroups.Engineer));
    }

    return false;
}

looking at the Umbraco source code, this seems to be hitting the database everytime, so I'm thinking this is the wrong way of doing it? Ideas?

IIRC Umbraco ties into Microsofts authentication so everything should be in Claims Not sure if this is the correct interface but looks like it IMemberManager - https://github.com/umbraco/Umbraco-CMS/blob/3157601724cd3780c38491b5593338c1e718ab84/src/Umbraco.Web.Common/Security/MemberManager.cs

IsMemberAuthorizedAsync

You could also use

await memberManager.GetCurrentMemberAsync();

But the member part of Umbraco definitly needs work..

var member =  await memberManager.GetCurrentMemberAsync();

returns a MemberIdentityUser, but member.Roles contains no Roles... So you need to use

var memberGroups = await memberManager.GetRolesAsync(member);

but this gets a list of

string

. No objects with a name and an ID So if you somewhere else use a memberGroup picker, that value is stored as an

Id

.. So you then need to get

var memberGroups = memberGroupService.GetByIds(memberGroupsIds).Select(group => group.Name);

to match them again xD

public virtual async Task IsMemberAuthorizedAsync( IEnumerable? allowTypes = null, IEnumerable? allowGroups = null, IEnumerable? allowMembers = null)

@Matt Wise I'd looked at the IMemberManager but forgotten about IsMemberAuthorizedAsync, that might just do the trick !!
