Yes, that page was my reference, but I couldn’t find the difference.
The only 1 I see now is that you are using own module to store data worker(DrabPoc.Presence, []), but the app should work w/o it.
After your instructions had same error.
Removed _build dir, restarted app, and now it works!

Oops, this is bad, it shouldn’t be like this.
Compilation of Drab.Presence depends on the config options, this must be an issue. I will try to hunt it down.

@grych debug info: I was done with Chat Example in Drab: Server Side User Interface Access and it was working fine.
Then I started adding Presence and got into trouble until removing the build.

Thanks for Drab - I am really enjoying it. I wanted to ask if this issue with Drab.Presence had been resolved. I am using 0.10.1 (Phoenix 1.4) and wonder if I have the same problem.
For example, if I create a stock app “my_app” (mix phx.new my_app), and do the following (let me apologize now if I am missing/screwing up a step):
- add
{:drab, "~> 0.10.1"}toconfig.exs mix deps.getmix drab.installmix drab.gen.commander Page- add
config :drab, :presence, truetoconfig.exs - add
Drab.Presenceto my supervision tree inlib/my_app/application.ex - add
import Drab.Presencetopage_commander.ex
I get the error below when I run mix phx.server:
(CompileError) lib/my_app_web/controllers/page_controller.ex:3:
module Drab.Presence is not loaded and could not be found
From this point if I rm -rf _build and mix phx.server again, everything recompiles and I get the same error.

Yes and no. I did the steps (edited below to be more accurate) and I get the same error. However - this time I did rm -rf _build and then when I restarted the server it recompiled with no error. That works for me!
That said - please let me re-document my steps as I did not record them 100% correctly the first time. I am using Phoenix 1.4, Elixir 1.7.4, Erlang/OTP 21.
mix phx.new my_app --no-ecto- add
{:drab, "~0.10.1"}tomix.exs mix deps.getmix drab.installmix drab.gen.commander Page- add
config: drab, :presence, truetoconfig.exs - add
Drab.Presenceto my supervision tree inlib/my_app/application.ex - add
import Drab.Presencetopage_commander.ex - note that
config: Drab, MyAppWeb.Endpoint, otp_app: my_appis inconfig.exs - run
mix phx.server
I deviated from the instructions in the docs in two respects:
-
The docs say to modify the supervision tree in
lib/my_app_web.ex; I’m assuming that where the supervision tree was specified in an older version of Phoenix? -
The docs say to make sure that
config: Drab, MyAppWeb.Endpoint, otp_app: my_app_webis set, notmy_app, which is what was inserted into my file by the generator. I admit I don’t really understand what that is doing. I did modify it tomy_app_weband get the same error, for what that is worth.
