Question

(This is NOT ABOUT OAUTH but about storing a key and a value)

I wrote a simple app that queries my twitter account and then process the tweets from my timeline.

I am able to obtain my oauth token and secret but as it turns out I can’t really store them on the filesystem on heroku for some unknown reason.

basically I have the following code:

  task :heroku => :environment do 
    desc "manually store the keys for heroku in oauth_path"
    File.open(oauth_path, 'w') do |f| 
      f.puts ENV['token']
      f.puts ENV['secret']
    end

    puts "Token and Secrent written to #{oauth_path}"
  end

this works on local filesystem but not on heroku.

I have a task which then opens oauth_path and then run the twitter app with those token and secret.

I have set up cron on heroku to execute rake myapp:pull

Any ideas how I can store the key value and then write my app as rake myapp:pull ??

You should set up an enviroment varible on heroku to store this information, it should not be stored inside a database since that could be potentially less secure.

You set keys like this:

$ cd myapp
$ heroku config:add S3_KEY=8N029N81 S3_SECRET=9s83109d3+583493190
Adding config vars:
  S3_KEY    => 8N029N81
  S3_SECRET => 9s83109d3+583493190
Restarting app...done.

And access them like this:

AWS::S3::Base.establish_connection!(
  :access_key_id     => ENV['S3_KEY'],
  :secret_access_key => ENV['S3_SECRET']
)

See the documentation for more info.
