How to deploy a Rails 7.1 app with Postgres and Kamal on a single server

module SessionSystemTestHelper
  def sign_in_as(user)
    visit root_url # any fast-to-load page will do

    cookie_jar = ActionDispatch::TestRequest.create.cookie_jar
    cookie_jar.signed[:session_token] = user.sessions.create.token
    page.driver.browser.manage.add_cookie(name: "session_token", value: cookie_jar[:session_token], sameSite: :Lax, httpOnly: true)
  end
end

For apps built before the image_processing gem became the default, the migration will involve two steps:

1. Migrating to the image processing syntax while still using ImageMagick;
2. Switching to Vips and updating the compression options;

Migrate to the image processing syntax

Before changing from ImageMagick to Vips, it's better to first test the new syntax and ensure everything is still working.

1. Move everything that has to do with compression to a saver hash:

variant(format: :jpg, strip: true, quality: 80)

This is for my personal use, things might not be correctly explained here. For the official docs please check https://github.com/airbnb/react-native-maps
