Lemonade is a simple, daemonized process for uploading your popular Instagram photos to Flickr. Popular = 'more than three likes.'
##Usage
$bundle exec ruby photo_daemon.rb start
tail log/poster.log -f to view output
##Features
- Runs as a background process.
- Caches photos you've already uploaded in Redis so you avoid the oh-so-awkward moment of uploading the same file twice.
- I'm thinking...
##Issues
- This is a demonstration only, polling one user. In a robust application, I'd cache or hit an endpoint to fetch the user-ids and access-tokens of all the users who had oauthed my Flickr and Instagram apps.
- You need to supply your own oauth-tokens for Flickr and IG. See below.
- No work has been put into monitoring for Instagram's heavy-handed api limits.
###Getting Redis to work, OSX
It's a little funky, which is why it's useful to run under something like Vagrant.
If not,
$brew install vagrant
Then $redis-server in a second terminal window. OR make sure it launches at boot:

###Getting a Flickr Auth Token Follow the awesome suggestions made here by http://blog.idifysolutions.com/2014/07/save-images-to-flickr-using-flickraw-gem/ Warning: it's very Rails-heavy.
###Getting an Instagram Auth Token There's no way around this, you'll need to register an app with Instagram so you can get a client ID and a client secret.
Once you do that, you can go through the pain of writing the front-end oauth route, or do this! You'll need to remember client-id, client-secret, and redirect-uri from above.
-
Use the following address: GET the following: https://api.instagram.com/oauth/authorize/?client_id=CLIENT-ID&redirect_uri=REDIRECT-URI&response_type=code It will respond with a code. Write that down.
-
Once you have the code param from above, enter the following cURL:
curl -F 'client_id=CLIENT-ID' -F 'client_secret=CLIENT-SECRET' -F 'grant_type=authorization_code' -F 'redirect_uri=REDIRECT-URI' -F 'code=CODE' -F 'aspect=media' https://api.instagram.com/oauth/access_token
- Your cURL will return JSON like this:
{"access_token":"ACCESS-TOKEN","user":{"username":"gxrobillard","bio":"Humorist. Open Sourcerer. Mad Soccer Dad. Some assembly required.","website":"http:\/\/alldaycoffee.net","profile_picture":"http:\/\/images.ak.instagram.com\/profiles\/profile_31741931_75sq_1334701202.jpg","full_name":"G. Xavier Robillard","id":"31741931"}}
####ToDo Implement a better method to manage env variables. Thinking a rake task?
