Heroku is serving old assets for Rails 5 application

Question

I've deployed a new version of a Rails 5 app on Heroku, running on cedar-14 stack. It didn't precompile while deploying, so I did heroku run rake assets:precompile manually. Still, I can see it includes old assets while requiring css and js files.

My files are in app/assets so it's not possible that directory isn't in assets compile path.

My config on application.rb and production.rb:

config.assets.compile = true

# I checked the environment variable, it responds to 'enabled',
# which would return true for the option.
config.public_file_server.enabled = ENV['RAILS_SERVE_STATIC_FILES'].present?

# Which I changed to expire old assets.
config.assets.version='1.1'

I tried these, but they didn't work:

• $ heroku restart
• $ heroku run rake assets:precompile
• $ heroku run rake assets:clobber

The weird thing with these is that they do not affect assets in heroku server, which I checked with $ heroku run ls public/assets. Even after $ rake assets:precompile, even though it says this:

WRITING /app/public/assets/application-{VERY_LONG_HASH}.js
WRITING /app/public/assets/application-{VERY_LONG_HASH}.js.gz
WRITING /app/public/assets/application-{VERY_LONG_HASH}.css
WRITING /app/public/assets/application-{VERY_LONG_HASH}.css.gz

when I peek with the $ heroku run ls public/assets, I still see old assets staying there.

EDIT: I solved it by deleting all the local assets in public/assets, recompiling them with $ rake assets:clean && rake assets:precompile and including these assets in my git repository. Here is one concern:

Shouldn't heroku be responsible of compiling my assets on the fly? I think I shouldn't be compiling my assets everytime I deploy my application. Thanks.

Answer 1

Run on local

RAILS_ENV=production bundle exec rake assets:precompile

Next git add .

Next got commit -m"assets precompile"

Next git push origin yourBranchName

Deploy on heroku and you are done
