I have this in the channel module:
def join("room:" <> user_id, _params, socket) do
{user_id, _} = Integer.parse(user_id)
%{id: id} = socket.assigns[:user]
case id == user_id do
true ->
{:ok, socket}
false ->
{:error, "This is not your solo channel!"}
end
end
And this inside user_socket.ex:
def connect(%{"token" => token}, socket) do
case Phauxth.Token.verify(socket, token, 86400) do
{:ok, user_id} ->
socket = assign(socket, :user, Repo.get!(Onlist.Accounts.User, user_id))
{:ok, socket}
{:error, _} ->
IO.puts "error"
:error
end
end
This is working fine, my question, is ti possible to subscribe a user to his own channel based on the socket socket.assigns:[user] without the need of him sending his user_id to def join("room:" <> user_id, _params, socket) do from JS?
How to rewrite the join method and make it extract the user_id from the socket and subscribe him to room:user_id?
