I’m getting an odd error in which a topic from another phoenix project is the subject of an unmatched topic warning when I start the phoenix server of a new phoenix project.
Below is the code for the user_socket.ex of the new phoenix project.
defmodule HelloWeb.UserSocket do
use Phoenix.Socket
## Channels
# channel "room:*", HelloWeb.RoomChannel
# Socket params are passed from the client and can
# be used to verify and authenticate a user. After
# verification, you can put default assigns into
# the socket that will be set for all channels, ie
#
# {:ok, assign(socket, :user_id, verified_user_id)}
#
# To deny connection, return `:error`.
#
# See `Phoenix.Token` documentation for examples in
# performing token verification on connect.
def connect(_params, socket, _connect_info) do
{:ok, socket}
end
# Socket id's are topics that allow you to identify all sockets for a given user:
#
# def id(socket), do: "user_socket:#{socket.assigns.user_id}"
#
# Would allow you to broadcast a "disconnect" event and terminate
# all active sockets and channels for a given user:
#
# HelloWeb.Endpoint.broadcast("user_socket:#{user.id}", "disconnect", %{})
#
# Returning `nil` makes this socket anonymous.
def id(_socket), do: nil
end
One can see that I have not yet written in any channel specifications.
Here are the warnings
