Hat system not drawing hats

[dingusnin]

Hello, I recently tried to make a hat system but the hats dont seem to be drawn on the player :/
here is my code

[lua]
hats = {}
players_have_hats = {}

function AddHat( unique , model, offsetV, offsetA , bone , scale)
hats[unique] = hats[unique] or {}
hats[unique].model = model
hats[unique].offsetV = offsetV
hats[unique].offsetA = offsetA
hats[unique].bone = bone
hats[unique].scale = scale
end

function SpawnHat(player , unique)
if !player:IsPlayer() then return end
if !player:IsValid() then return end
if !hats[unique] then return end
local index = player:EntIndex()
players_have_hats[index] = players_have_hats[index] or {}
players_have_hats[index].hat = unique

end

function SetHat(player,hat)
hat:SetOwner(player)
end

function GetHat(player)
for k,v in pairs(ents.GetAll()) do
if v:GetOwner() == player then
return v
else
return false
end
end
end

AddHat("Barrel","models/props_c17/oildrum001_explosive.mdl",Vector(0,0,0), Angle(0,0,0),"ValveBiped.Bip01_Head1",45)

function DrawHats(ply)
local index = ply:GetIndex()
local Player = ply
if !players_have_hats[index] then return end
local unique = players_have_hats[index].hat
local BoneIndx = Player:LookupBone(hats[unique].bone)
local BonePos, BoneAng = Player:GetBonePosition( BoneIndx )
local offsetV = BonePos + hats[unique].offsetV
local offsetA = BoneAng + hats[unique].offsetA
local scale = hats[unique].scale //* Player:GetNetworkedFloat("PlScale")
local hat = hat or ClientsideModel(hats[unique].model, RENDERGROUP_OPAQUE)
hat:SetPos(offsetV)
hat:SetAngles(offsetA)
hat:SetModelScale(Vector(scale,scale,scale))
SetHat(Player,hat)
hat:SetNoDraw(true)
end

hook.Add("PostPlayerDraw","hat.draw",function(ply)
DrawHats(ply)
local hat = GetHat(ply)
hat:DrawModel()
end)
[/lua]

There are no erorrs at all.
To Add a hat to somone i did

lua_run SpawnHat(Entity(1),"Barrel")
