What is your T-shirt size?

Get your Half Chest size:

• Get one of your T-shirts and lay it flat on a table.
• Measure the distance (in cm) across the chest from side to side immediately below the armpit.

Tadaaa! That's your Half Chest measurement.

• Men's XS (Half Chest: 47cm, Length 67cm)

web: bundle exec puma -C config/puma.rb -p $PORT
worker: bundle exec sidekiq -e $RAILS_ENV -q default -q mailers

# By default, sidekiq only operates on the `default` queue
# So if you do `Mailer.new(...).deliver_later`, those are queued to the `mailers` queue
# Hence you need to explicitly tell Sidekiq to operate on `mailers` queue too
# You can also put this into sidekiq.yml

Protecting Your Secrets

User Authentication

User Authentication is an important part of most web applications.

There are gems that can provide awesome authentication functionality out of the box, like Devise and Clearance.

However, it's also a good exercise in learning to implement our own authentication and understand the concepts for building out such a functionality.

Country Select

Currently, we see a text field for country_code when creating a gram.

Let's replace that with a select dropdown with actual country names.

1. Install Gem

Add to your Gemfile, and run bundle install in your terminal after that.

Image Upload Part 2

In part 1, we learned how to set up a simple image upload using Carrierwave and Cloudinary.

Although we are able to upload an image, but it lacks image manipulation functionalities, i.e. cropping.

Let's improve our image upload to allow for cropping!

Usually, this involves JavaScript and fortunately, Cloudinary has a JavaScript library which we could use!
