Hi Chris,
Yet another good tutorial you made. I must say I always use option 1.

Posted in Realtime browser updates with Cable Ready Discussion

I have an application using ActionCable broadcasting to about 100 TV screens when a new event happens.
This works great on local machine but on server (centOS, NGINX) I see a lot of Broken Pipe messages and many screens don't receive the updates.
Would this be a better solution or have the same problem since it's using the same technology under the hood? Please advice

Posted in Root route bypassing before_action

we have a posts_controller which takes a slug to render the correct page.
posts_controller inherits from application_controller which has a couple of before_actions

routes.rb has the following root

    root  'posts#show_post'

The before_actions are not called when going to localhost:3000 which renders the correct post.

also in the log i don't see the show_post action being called.
What am I missing here?

In our application we generate several reports. Instead of downloading them as Excel or CSV want to render them similar to Excel/Google sheet

Have a simple Ruby script to do this.

Your model is wrong it's better to have a model named partner for example which has a partner type. Now you can seed it with partner types like Vendor, Customer, Supplier Both, whatever you want

class CreatePartnerTypes < ActiveRecord::Migration[5.2]
  def change
    create_table :partner_types do |t|
      t.string :name
    add_index :partner_types, :name,  unique: true

class CreatePartners < ActiveRecord::Migration[5.2]
  def change
    create_table :partners do |t|
      t.references :company
      t.references :partner_type
      t.string :name
      t.string :address
      t.string :postal_code
      t.string :city
      t.references :state

Posted in Is there an episode on Post Production Updates?

  1. Make sure to work from different branches in git (e.g. master branch is on your production server and develop is on your staging and local)
  2. Do not make changes to your to exisiting migrations, if you need to change/create models create a migration for it.
  3. In case you add a field to a modal and you are using it in a control flow make sure to set a default value
  4. New Controllers/Views can be added like normal
  5. After local testing deploy to your staging server * git pull * rails db:migrate * start your server
  6. If all is verified do the same on production from your master branch, restart your services

My system is using a post model with friendly_id so the calls are /name_of_the_post and this works great.
The initial home page is also a post so in routes.rb I have

    root 'home#index'
        get ':slug', to: 'posts#show_post', as: 'show_post'

    My HomeController has the following index action
        def index
        redirect_to '/home'
    The PostsController will pick up home slug and show the post, however my URL is now localhost:3000/home and I want it to be 

    How can I achieve this stripping the home slug (only for home)
