TurboStreams Guide Failure

I’m trying to learn TurboStreams following this simple Hotwire Guide but the page doesn’t update after I add an entry in the console unless I refresh the browser.

Redis is running:

$ redis-cli -p 6379 ping

The default Gemfile had redis commented out, so I enabled it:

# Use Redis adapter to run Action Cable in production
gem "redis", "~> 4.0"

I thought cable.yml might be the problem, so I added redis to the development section, but it didn’t seem to make a difference.

  adapter: redis
  url: redis://localhost:6379/1

  adapter: test

  adapter: redis
  url: <%= ENV.fetch("REDIS_URL") { "redis://localhost:6379/1" } %>
  channel_prefix: simple_hotwire_production

On create, my bin/dev log message looks like the one in the post, but it comes out in the rails console window rather than the server window.

On Post.destroy_all, my bin/dev log message is different than than the one in the post:

[ActionCable] Broadcasting to posts: "<turbo-stream action=\"remove\" target=\"post_11\"></turbo-stream>"

My turbo-cable-stream-source looks the same as the blog post, but without the connected=“” property:

<turbo-cable-stream-source channel="Turbo::StreamsChannel" signed-stream-name="InBvc3RzIg==--7b2eb3d475ba281629a0bb2229d5f2dc13c50febb0fcb311775484a89454a55b"></turbo-cable-stream-source>

My turbo frame output looks the same:

<turbo-frame id="post_11">..</turbo-frame>
<turbo-frame id="post_12">..</turbo-frame>

Here’s the code:

# Procfile.dev
web: bin/rails server -p 3000
css: bin/rails tailwindcss:watch
redis: redis-server
# posts_controller.rb
class PostsController < ApplicationController
  def index
    @posts = Post.all
# post.rb
class Post < ApplicationRecord
    broadcasts_to -> (post) { :posts }
# index.html.erb
  <h1 class="font-bold text-4xl">Posts#index</h1>
  <p>Find me in app/views/posts/index.html.erb</p>

  <%= turbo_stream_from :posts %>
  <div id="posts">
    <%= render @posts %>
# _post.html.erb
<%= turbo_frame_tag dom_id(post) do %>
  <div class="border flex-col mt-2">
    <%= post.title %>
    <%= post.article %>
<% end %>

Can anyone see what I’m missing or give me an idea of how to debug it?

Redis doesn’t show any activity when adding new posts from the rails console:

$ redis-cli monitor

irb(main):003:0> Post.create(title: 'hello', article: 'test')

But it does if I add a key-value directly from the command line:

$ redis-cli monitor
1689983297.790074 [0] "SET" "key0" "value0"

$ redis-cli SET "key0" "value0"

So Redis works, but maybe Rails is not able to send data to Redis for some reason.

Fixed by switching from asdf to rtx for version management and upgrading Ruby to 3.2.2p53 and Rails to 7.0.6.
