Use RACK_ENV for heroku? about figaro HOT 7 CLOSED

Thanks for pointing that out. Could you please submit a pull request?

Do you plan to work on this? If not, I can when I'm free (someday)!

Sorry, I forgot about this one :) Well, I won't have the time to code until early March (vacation, yeah!).

I just noticed this issue mentions the same redundant key as issue #35.

With pull request #39, at least for Rails apps, the Figaro Rake task you mention (rake figaro:heroku) works, without setting either RAILS_ENV or RACK_ENV as Heroku config keys.

To enable pure Rack apps, the Figaro Rake task code could use RACK_ENV instead. I tried this, and it worked:

$ heroku run "echo \$RACK_ENV"
Running `echo $RACK_ENV` attached to terminal... up, run.6334
production

Figaro isn't intended for pure Rack apps. The new way in which Figaro looks for your remote Rails.env (as of v0.6.2) should properly read RAILS_ENV from Heroku.

@laserlemon Makes sense, this is a nice compromise. Thank you!
