WiserChat

Awesome chat on fire!

WiserChat only support Rails >= 3.2 with jQuery.

The following items are required:

• Redis should be installed in the server, please see http://redis.io.
• User model should be available and it should have a name method that returns the user name for the chat.
• WiserChat should be used only when there's a user logged in - current_user method should be available.

Include the following lines in your Gemfile:

gem 'redis', '3.2.0'
gem 'websocket-rails', '~> 0.7.0'
gem 'wiser_chat', '~> 0.1.4'

Then run:

bundle install

After installing the gems, you're now ready to install WiserChat by running this command:

bundle exec rails generate wiser_chat:install

The install command will generate the necessary files as well as the migration for the database. Now, run the migration to create the database table:

bundle exec rake db:migrate

Lastly, remove the Rack::Lock middleware by adding this line at the end of your development.rb file:

config.middleware.delete Rack::Lock

WiserChat will use websocket and redis, you need to start the websocket server:

bundle exec rake websocket_rails:start_server

The websocket logs will be available at log/websocket_rails.log and log/websocket_rails_server.log.

You can always use this helper method in your view:

= wiser_chat(@channel_name)

You need to specify the @channel_name to group the chat conversations. You can have different channels in different pages, but you cannot have multiple channels in a single page.

Channel name is very sensitive, use alpha-numeric characters only. In other words, do not use any special characters in your channel name.

Include the wiser_chat stylesheet into your app/assets/stylesheets/application.css:

*= require wiser_chat

By default, the chat box will be hidden and you need to toggle the #wiser-chat element to display it. But you can create a link with toggle_chat class to add a display control for the chat box.

= link_to "Chat", "#", class: "toggle_chat"

However, you can always customize it or event create your own appearance by editing the app/assets/stylesheets/wiser_chat.css.

You need to run the websocket in your server and adding the codes below will make it easier for you to do it using the capistrano commands. Append this in your deploy.rb file:

set :stage, lambda{ config_name.split(':').last }
namespace :websocket do
  desc 'Stop websocket deamon'
  task :stop do
    on roles(:app), in: :sequence, wait: 5 do
      within current_path do
        websocket_pid = current_path.join('tmp/pids/websocket_rails.pid')
        if test("[ -f #{websocket_pid} ]") then
          with rails_env: fetch(:stage) do
            rake 'websocket_rails:stop_server'
          end
        else
          info "WebsocketRails is not running, not need to be stopped."
        end
      end
    end
  end

  desc 'Start websocket deamon'
  task :start do
    on roles(:app), in: :sequence, wait: 5 do
      within current_path do
        with rails_env: fetch(:stage) do
          info 'Start WebsocketRails server'
          rake 'websocket_rails:start_server'
        end
      end
    end
  end
end

After that, these capistrano commands will do the work:

bundle exec cap production websocket:start

You can also kill the websocket using this capistrano command:

bundle exec cap production websocket:stop
