Secureactionbuttontemplate with a variable attribute

I've made a quick WeakAura for tracking buffs/debuffs for myself and the other tank in our raid, with a button that pops up on Readycheck if there is no focus.
Left clicking the button targets the other tank, right click focuses.

At present I have this (which works fine, but only on our mains):

Code:

local region = aura_env.region

local b = CreateFrame("Button", "FocusBtn", region, "SecureActionButtonTemplate")

b:RegisterForClicks("LeftButtonUp","RightButtonUp")

b:SetAllPoints(region)



if UnitName("player") == "Niian" then

    b:SetAttribute("*type1", "macro")

    b:SetAttribute("macrotext", "/target Aswm")

end



if UnitName("player") == "Aswm" then

    b:SetAttribute("*type1", "macro")

    b:SetAttribute("macrotext", "/target Niian")

end



b:SetAttribute("*type2","focus")

I can easily enough scan through the raid and create a variable with the name of the other tank, but is there a way that I can then use this variable in a secureactionbuttontemplate button? I've tried a few times but haven't been able to get it to work.
Thanks!

You can just call button:SetAttribute() again when you need to update it. This can't be done during combat however.

For example:

Lua Code:

local button=CreateFrame("Button",nil,aura_env.region,"SecureActionButtonTemplate");
button:RegisterForClicks("LeftButtonUp","RightButtonUp");
button:SetAllPoints(aura_env.region);
 
button:SetAttribute("*type1","target");
button:SetAttribute("*type2","focus");
button:SetAttribute("unit","none");--   Special UnitID for "no unit"
 
button:RegisterEvent("PLAYER_ROLES_ASSIGNED");
button:RegisterEvent("GROUP_ROSTER_UPDATE");
button:RegisterEvent("RAID_ROSTER_UPDATE");
button:RegisterEvent("PLAYER_REGEN_ENABLED");
button:SetScript("OnEvent",function(self)
    if not InCombatLockdown() then--    Can't update in combat
        local unit="none";
        if IsInRaid() then
            for i=1,MAX_RAID_MEMBERS do
                local raidunit="raid"..i;
                local raidid=UnitInRaid(raidunit);--    Unit-to-ID mappings aren't guaranteed
                if raidid and not UnitIsUnit(raidunit,"player") and (select(10,GetRaidRosterInfo(raidid))=="maintank" or UnitGroupRolesAssigned(raidunit)=="TANK") then
                    unit=raidunit; break;
                end
            end
        end
        self:SetAttribute("unit",unit);
    end
end);

Thank you very much!
I'll have a look at this soon (once I'm done smashing my face against Torghast)
