问题
So im in the process of deploying my code via heroku but have recently encountered 'were sorry but something went wrong' error when going to the site. Not entirely sure the cause of this Ive gone back and tried using 'heroku rake db:reset command' (that may not be verbatim) but Im a bit confused in regards to what to do to fix this.

回答1:
Did you have a syntax error in your javascript file? When you deploy to heroku, does it show that it fails to precompile your assets during the deployment?
