Importing all files from folder

• Now when you want to create a separated folder to your javascripts you need to import like bellow, bellow my folder is on app/javascripts/controllers:

  $ = require('jquery')
  require('controllers')

• Inside this folder you need the archive index.js what will contains the following code to import all files

  const channels = require.context('.', true, /\.coffee$/)
  channels.keys().forEach(channels)

action mailbox

• Another form to send emails now, with a simple and completed type to configure the api to send emails, callbacks and a lot of more

  rails action_mailbox:install
  rails db:migrate
  rails credentials:edit

  To use mailgun use configurations bellow:

  action_mailbox:
    mailgun_api_key: ...

  production.rb

  config.action_mailbox.ingress = :mailgun

  application_mailbox.rb

  class ApplicationMailbox < ActionMailbox::Base
    routing /^save@/i     => :forwards
    routing /@replies\./i => :replies
  end

  rails generate mailbox forwards

  forwards_mailbox.rb

  class ForwardsMailbox < ApplicationMailbox
    # Callbacks specify prerequisites to processing
    before_processing :require_forward
   
    def process
      if forwarder.buckets.one?
        record_forward
      else
        stage_forward_and_request_more_details
      end
    end
   
    private
      def require_forward
        unless message.forward?
          # Use Action Mailers to bounce incoming emails back to sender – this halts processing
          bounce_with Forwards::BounceMailer.missing_forward(
            inbound_email, forwarder: forwarder
          )
        end
      end
   
      def forwarder
        @forwarder ||= Person.where(email_address: mail.from)
      end
   
      def record_forward
        forwarder.buckets.first.record \
          Forward.new forwarder: forwarder, subject: message.subject, content: mail.content
      end
   
      def stage_forward_and_request_more_details
        Forwards::RoutingMailer.choose_project(mail).deliver_now
      end
  end

action text

• well i think that i will use it so much now the rails action text to get a rich text to get text bold or underlined etc...

rails action_text:install

app/models/message.rb

class Message < ApplicationRecord
  has_rich_text :content
end

app/views/messages/_form.html.erb

<%= form_with model: message do |form| %>
  <div class="field">
    <%= form.label :content %>
    <%= form.rich_text_area :content %>
  </div>
<% end %>

show this content whatever you want like: app/views/messages/show.html.erb

<%= @message.content %>

app/controllers/messages_controller.rb

class MessagesController < ApplicationController
  def create
    message = Message.create! params.require(:message).permit(:title, :content)
    redirect_to message
  end
end

New commands

User.pick(:name) || User.find(params[:id]).pick(:name) # it is like pluck

rails db:prepare

insert_all || insert_all! || upsert_all # active record changes
