title: Pass temporary ENV variables to Heroku
body: <p>There are times where I'd like my Heroku console to do something differently but only for that instance. While I'm able to control this through command line arguments it can get a little long/messy.</p>
  
  <p>I'm trying to pass temporary ENV vars to Heroku when booting a console but am so far unable to. I'd like to run <code>SOME_VAR=some_value heroku run console --app myapp</code> but once Rails boots, I do not have <code>ENV['SOME_VAR']</code>.</p>
  
  <p>I know I can set this and then delete it from the Heroku website but that restarts the server which I'd like to avoid.</p>
  
  <h1>tl;dr</h1>
  
  <p>Is there a way to pass temporary <code>ENV</code> vars to Rails apps running on Heroku without setting them in the Heroku dashboard?</p>
