Where does Heroku store compiled handlebars.js templates?

Question

I've upgraded the handlebars-source in my Rails/Ember.js app to 1.3.0 and am getting the following error after deploying to my Heroku staging environment.

Template was precompiled with an older version of Handlebars than the current runtime. Please update your precompiler to a newer version (>= 1.0.0) or downgrade your runtime to an older version (== 1.0.0-rc.3).

It seems like I should be able to delete these templates and recompile with the newer version of handlebars, but cannot figure out how. I have tried rake tmp:clear and rake assets:clobber on the Heroku server and redeploying, but it's still giving the same error.

Are these templates stored somewhere else where I can delete and have Heroku recompile them?

Other related gem versions:

• ember-rails (0.14.1)
• ember-source (1.5.0.beta.4)

Answer 1

I'm still curious if there's a better way to do this, but the only way I could get it working was by changing the asset version number in config/production.rb file and redeploying:

# Version of your assets, change this if you want to expire all your assets.
config.assets.version = '2.0'
