I am using the vs-code extension https://marketplace.visualstudio.com/items?itemName=JakeBecker.elixir-ls
Environment details
Erlang/OTP 21 [erts-10.2.1] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1] [hipe] [dtrace]
Elixir 1.7.4 (compiled with Erlang/OTP 21)
My Guardian module code is as
defmodule Epos.Guardian do
use Guardian,
otp_app: :epos
use Guardian.Permissions.Bitwise
def subject_for_token(%{} = user, _claims) do
# You can use any value for the subject of your token but
# it should be useful in retrieving the resource later, see
# how it being used on `resource_from_claims/1` function.
# A unique `id` is a good subject, a non-unique email address
# is a poor subject.
sub = to_string(user.users_id)
{:ok, sub}
end
def subject_for_token(_, _) do
{:error, :reason_for_error}
end
def resource_from_claims(%{} = claims) do
# Here we'll look up our resource from the claims, the subject can be
# found in the `"sub"` key. In `above subject_for_token/2` we returned
# the resource id so here we'll rely on that to look it up.
id = claims["sub"]
resource = Epos.Accounts.get_user!(id)
{:ok, resource}
end
def resource_from_claims(_claims) do
{:error, :reason_for_error}
end
def build_claims(claims, _resource, opts) do
claims =
claims
|> encode_permissions_into_claims!(Keyword.get(opts, :permissions))
{:ok, claims}
end
end
The moment I include this use Guardian.Permissions.Bitwise i get the following warnings in vscode
The attempt to match a term of type ‘Elixir.MapSet’:t(_) against the pattern #{‘struct’:=‘Elixir.MapSet’} breaks the opacity of the term
Function ‘do_any_permissions?’/2 has no local return
The created fun has no local return
Invalid type specification for function ‘Elixir.Epos.Guardian’:available_permissions/0. The success typing is () → #{‘admin’:=[‘expense_write’ | ‘products’ | ‘receivings_write’ | ‘sales’ | ‘stock’,…], ‘basic_user’:=[‘sales’ | ‘stock’,…], ‘super_admin’:=[‘all_access’,…]}
I am very new to elixir in hello world level. I tried googling but I am failed to figure the reason for this. Could somebody please help me on this?
