I have a Turbo Stream which is not updating the view and I'm not sure why. I have two other broadcasts setup in a similar configuration which are working fine.

Everything looks like it should be working from what I can see, I'm just not getting the update on the front end. Am I missing something obvious?

# partial
<%= turbo_stream_from 'team_players' %>
<div id="players_<%= dom_id(team)%>"
    <% team.players.each do |player| %>
        <%= render player %>
    <% end %>
</div>

# player model
class Player < ApplicationRecord
belongs_to :team

    after_create_commit  do
        broadcast_prepend_to(
            'team_players',
            target: "players_team_#{team.id}",
            locals: { player: self }
        )

    end
end

Any help or pointers are appreciated!

It looks as though I had missed Step 4 in the turbo-rails installation process: https://github.com/hotwired/turbo-rails#installation

After running: ./bin/rails turbo:install:redis everything worked from the command line.

Without that step, things still worked from a separate browser session.

Thanks to David Colby on Twitter for finding the fix.

  • indeed "The Async adapter does not support Turbo Stream broadcasting", thank you! – user1519240 Jun 19 '23 at 17:17
  • Just had similar. I hadn't specified the redis url in config/cable.yml for development. The OP, after seeing the broadcasting message in the console, should have seen a line appear in the server log: Turbo::StreamsChannel transmitting " – jnicho02 Jun 23 '23 at 08:42
  • Just got got by this. Is there an error message that we're supposed to have caught to see that something isn't properly configured? as far as i can tell it's a totally silent failure – aidan Jul 11 '23 at 18:41
