Posted in Group Chat with ActionCable: Part 4 Discussion

found it! :)

my message_relay_job.rb file was showing:


message: MessageController.render(message)

instead of:


message: MessagesController.render(message)

It's working a treat now :)

Posted in Group Chat with ActionCable: Part 4 Discussion

Hey Chris, i've been following the videos for the group chat and so far they're awesome (as are all the videos of yours that i've watched).
I've run into a bit of a stale point though, in your video around 15:31 we're logging the message data to the console, but seems it's not working for me, nothing is printing to the chrome console.

my rails server output is showing:

Which seems all good, just wondered if you had any input why this wouldn't be showing the console.log data

chatrooms.coffee:


App.chatrooms = App.cable.subscriptions.create "ChatroomsChannel",
connected: ->

disconnected: ->

received: (data) ->
console.log data

message_relay_job:


class MessageRelayJob < ApplicationJob
queue_as :default

def perform(message)
ActionCable.server.broadcast "chatrooms:#{message.chatroom.id}", {
message: MessageController.render(message),
chatroom_id: message.chatroom.id
}
end
end

chatrooms_channel:


class ChatroomsChannel < ApplicationCable::Channel
def subscribed
current_user.chatrooms.each do |chatroom|
stream_from "chatrooms:#{chatroom.id}"
end
end

def unsubscribed
stop_all_streams
end
end

not sure what else you would need to check? if you need my repo it's here

Hope you can help :)

Hey Chris and Magzhan,

I've got the same problem at the moment with my nibli site (chris you'll remember doing the code cast for me:) )

I've check the production.log but nothing there, i've also checked the /var/log/nginx/error.log and it's got something to do with the table lead

App 2163 stdout: Processing by PagesController#index as HTML
App 2163 stdout: PG::UndefinedTable: ERROR: relation "leads" does not exist

App 2163 stdout: ORDER BY a.attnum
App 2163 stdout:
App 2163 stdout: Completed 500 Internal Server Error in 2ms

I thought that when we do the created the database it would do all the tables, how do i register them? do i have to do rake db:migrate?
