How to run this app

Everything is within docker-compose, so you need Docker!

You'll first need to run the first-time setups, to create the docker container and the seed data:

docker-compose build web
docker-compose run --rm web bundle exec rails runner "org = Organisation.create!(name: 'Example Organisation', subdomain: 'example', creator: 'example'); user = User.create!(name: 'Jo Citizen', email: '[e-mail]', password: '[e-mail]'); OrganisationUser.create!(user: user, organisation: org)"

Then just:

docker-compose up

Navigate to http://login.lvh.me:3000/sessions/new

Login with the sample data username/password of:

• Username: [e-mail]
• Password: [e-mail]

Desired outcome

What I want is for

1. users to login at http://login.lvh.me:3000/sessions/new (note, the subdomain login)
2. once they're authenticated, they get redirected to their subdomain, e.g. http://my-org.lvh.me:3000/.

Problem

I'm missing something in my implementation, because, I can see that the authentication is successful, and the app log shows it's redirecting to "http://example.lvh.me:3000/users/1", but then when that controller loads, the session must be different, because the app thinks the user isn't logged in.

I have already set:

• config/application.rb to config.session_store :cookie_store, key: '_my_app_session', domain: :all, tld_length: 2
• config/application.rb to config.hosts << ".lvh.me"

I do not use Devise. I use has_secure_password and a before_action :require_login within ApplicationController.

When the user submits the login form, it:

1. submits to app/controllers/sessions_controller.rb#create, which then redirects redirect_to user_url(user, subdomain: user.organisations.first.subdomain), allow_other_host: true

2. That then loads the show action in the Users controller, which calls the ApplicationController before_action require_login.

3. At that point, the Session controller creates the session cookie and redirects to the subdomain URL, which then runs the before_action :require_login, and investigating that, the session isn't set.. any I've troubleshooted all I can think of. I'm missing something and need someone else's eyes.
