I'm currently facing the issue that my messages aren't saved into the database. I thought to problem would lie within in my setup, since I use sqlite3.

But there must be something else... When I start my server the command prompt says MessagesChannel is streaming from conversation_ instead it should conversation_1

Also when I try to send a message the command prompt says the following

No template found for MessagesController#create rendering head :no_content

My messages_channel.rb

class MessagesChannel < ApplicationCable::Channel
 def subscribed
 stream_from "conversation_#params[:id]"
 end
end

My messages.coffee

$(() ->
App.messages = App.cable.subscriptions.create channel: 'MessagesChannel', id: $('#conversation_id').val() ,
 received: (data) ->
 $('#new_message')[0].reset()
 $('#chat').prepend data.message
)

MessagesController

class MessagesController < ApplicationController
 before_action :authenticate_user!
 before_action :set_conversation

 def index
 if current_user == @conversation.sender || current_user == @conversation.recipient
 @other = current_user == @conversation.sender ? @conversation.recipient : @conversation.sender
 @messages = @conversation.messages.order("created_at DESC")
 else
 redirect_to conversations_path, alert: "You don't have permission."
 end
 end

 def create
 @message = @conversation.messages.new(message_params)
 @messages = @conversation.messages.order("created_at DESC")

 if @message.save
 ActionCable.server.broadcast "conversation_#@conversation.id", message: render_message(@message)
 redirect_to conversation_messages_path(@conversation)
 end
 end


 private

 def render_message(message)
 self.render(partial: 'messages/message', locals: message: message)
 end

 def set_conversation
 @conversation = Conversation.find(params[:conversation_id])
 end

 def message_params
 params.require(:message).permit(:context, :user_id)
 end
end

Connection.rb

module ApplicationCable
 class Connection < ActionCable::Connection::Base
 end
end

Ohh! you have missed the connection so you should configure the connection file as like

module ApplicationCable
 class Connection < ActionCable::Connection::Base
 identified_by :current_user

 def connect
 self.current_user = find_verified_user
 end

 protected

 def find_verified_user
 if (current_user = env['warden'].user) //Devise authentication
 current_user
 else
 reject_unauthorized_connection
 end
 end
 end
end

here is I have made a cheating app see this
