Trailer Swift

=============

Tour tracking

Developer Start-up

Notes for Mac OS X.

Make sure XCode is installed. You can get the installer from the App Store and then run that to do the actual installation.

Ruby and Rails

Install RVM, following this guide.

bash < <(curl -s https://rvm.beginrescueend.com/install/rvm)

Place in ~/.bash_profile as the very last line

[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"

Start a new terminal window

rvm install 2.0.0

This will install and compile Ruby. This may take a few minutes.

Install postgres database

I haven't used it yet, but I hear the easiest way to run postgres on your development machine is to use postgres.app from the folks at heroku. It looks like it should work without needing any configuration.

postgres.app

Git the code

Clone the git repository

git clone https://github.com/philipkobernik/trailerswift.git

cd trailerswift
(rvm will prompt you now, follow instructions to accept the .rvmrc file)

Install gem dependencies

bundle install

If you get an error about using the bundle command, you will need to go install rubygems

Create the database

rake db:create

Migrate the database

This task applies database migrations to your db to create tables

rake db:migrate

Start the application

Spin up the server and verify that the application works:

rails server
open http://localhost:3000

A browser window should open and display something

Run the specs?

I don't remember if there are any specs yet.

rake db:test:prepare
rspec spec/

Notes / thoughts

Current:

• app loads location lat/lngs from db
• assumes that most recent lat/lng is position of trailer
• requires reload to see updates...

Imagined (real-time magic):

• app bootstraps existing data points, existing photos
• gets real-time updates on locations, animates van and draws line
• gets real-time updates on photos tagged #TrailerSwift posts them at real location OR user's location
• gets real-time updates on photos tagged #HeyMarseilles

App caches photos in DB by subscribing to the tags TrailerSwift and HeyMarseilles

App caches photos posted by HM instagram account... displays these more prominently

Pieces involved:

Realtime -- integrate with pubnub/pusher for push updates

Instagram -- InstagramClient that subscribes to

• hey marseilles user new photos
• tag: TrailerSwift
• tag: HeyMarseilles

Subscription flow needs:

• endpoint for subscription callback http://instagram.com/developer/realtime/
• respond to GET by echoing the challenge string
• respond to POST request of new photos...

SUBSCRIPTION does not need access_token.
