Phoenix 1.2 vs 1.3 isn’t a problem here. While we added AppWeb naming, it’s just a module name. What the elixir stack trace is telling us is that AppChat.PrivateChannel does not exist. From your provided snippets, the user socket channel matches the defmodule AppChat.PrivateChannel, but is it possible you renamed these in your example? Can you include your, current, exact, user_socket.ex and private_channel.ex, along with a current elixir stack trace? Thanks!

Yep, I stopped and restarted the phoenix server to make sure all the files were compiled and up to date. I restarted my angularjs app, was able to connect to my user channel but not my private channel. Still says module is not available and join/3 undefined.

We need to find out why the module is unavailable before we try to delve into the undefined function. Well I do assume, that the undefined function is just a follow up of the missing module and will just work after we fixed the problem with the module.
Can you extract a minimal version that shows the problem and put it on github?

The 3 files you see there are exact. All I’ve been trying to do so far is to make sure that I can connect to these two channel before I can proceed to other stuff. About the elixir stack trace, I added the truncate: infinity option in the config.exs and ran phoenix like this: iex -S mix phoenix.server and the stack trace that I got in the console when trying to start a private chat was this:
[info] JOIN private:3:3 to AppChat.PrivateChannel
Transport: Phoenix.Transports.WebSocket
Parameters: %{}
[error] an exception was raised:

Which is matches the stacktrace from my second post? Is this what you wanted?

Here is something strange, If I start up elixir interactive and type AppChat.PrivateChannel, it finds the module. What does that tell you?

Something basic must be wrong here. If you can’t push your code to GitHub for us to look at, can you double check that you named your AppChat.PrivateChannel with “.ex” and not something like “.exs” ? If your code is as provided, then that’s the only obvious thing that could be going wrong. The error is a basic one to fix, we just need to find out why AppChat.PrivateChannel is undefined. If the code is as you claim, then the module isn’t being compiled for another reason, such as extension.

Yes I’m convince that it is something on the client side.
I changed my user_channel.ex to this:
defmodule AppChat.UserChannel do
use AppChat.Web, :channel
def join("user:" <> user_id, _payload, socket) do
if socket.assigns.current_user.id == String.to_integer(user_id) do
{:ok, socket}
else
{:error, %{reason: "unauthorized"}}
end
end
def join("private:" <> users_string, _payload, socket) do
if users_string |> String.split(":") |> Enum.member?(to_string(socket.assigns.current_user.id)) do
{:ok, %{}, socket}
else
{:error, %{reason: "unauthorized"}}
end
end
end
and my user_socket to this:
defmodule AppChat.UserSocket do
use Phoenix.Socket
channel "user:*", AppChat.UserChannel
channel "private:*", AppChat.UserChannel
transport :websocket, Phoenix.Transports.WebSocket
def connect(%{ "user_id" => id }, socket) do
current_user = AppChat.Repo.get(AppChat.User, String.to_integer(id))
{:ok, assign(socket, :current_user, current_user)}
end
def id(socket), do: "user_socket:#{socket.assigns.current_user.id}"
end
and when I do user:3 it’s fine and says that it joined and when I do private:3:3 or even private:3 it says that UserChannel module is not available. So how it can say that a module is available in one instance and then the same module not available in another instance?

- Can you provide a minified project for us to reproduce the issue?
- Are you able to reproduce the issue with phoenix 1.3?
