WoWInterface - Summon Random Favorite Mount [Improved]

I have created these global functions for my addon. "SummonRandomFavoriteMount()" has one difference from "C_MountJournal.SummonByID(0)"... Instead of only dismounting, if mounted (normal for that button); my function will dismount and mount the new mount in one command. I thought this might help others.

Also does anyone know of a good way to load an addon, followed by code execution involving that addon? That would be a nice tweak to this.

Edit: If this fails it's because the random mount chosen is the current mount.

Code:

-- Call after Blizzard's addon "Blizzard_Collections" is loaded

MountJournalSummonRandomFavoriteButton:SetScript("OnClick", SummonRandomFavoriteMount);

Code:

function GetOneFavoriteMount()

        local mountIdTable = C_MountJournal.GetMountIDs();

        local results = { };

        for idx = 1, #mountIdTable, 1 do

                local mountId = mountIdTable[idx];

                local _, _, _, _, isUsable, _, isFavorite = C_MountJournal.GetMountInfoByID(mountId)

                if (mountId and isFavorite and isUsable) then

                        table.insert(results, mountId);

                end

        end

        if (#results > 0) then

                local rand = results[math.random(1, #results)];

                return C_MountJournal.GetMountInfoByID(rand);

        end

end



function SummonRandomFavoriteMount()

        local _, _, _, _, _, _, _, _, _, _, _, mountId = GetOneFavoriteMount();

        C_MountJournal.SummonByID(mountId);

end
