I've just started using the asset_sync gem and my assets seem to be being compiled out of order, with Sass files unabled to access variables defined in other Sass files. What would really help me narrow down the issue is being able to see exactly what is going on during precompilation, but both rake assets:precompile
and heroku run rake assets:precompile
doesn't seem to offer a verbose option. All I get is some higher level output followed by a rake aborted!
and a stack trace. Tailing heroku logs gets me nothing, so how can I get a more detailed log of what is going on during asset precompilation on Heroku?
rake assets:precompile. We use rake assets:precompile to precompile our assets before pushing code to production. This command precompiles assets and places them under the public/assets directory in our Rails application.
To compile your assets locally, run the assets:precompile task locally on your app. Make sure to use the production environment so that the production version of your assets are generated. A public/assets directory will be created. Inside this directory you'll find a manifest.
Turns out a combination of the following gets you some more verbocity. You get output when a file is precompiled, but not as it is being precompiled, so if it hangs you can't see what it's choked on.
Use the --trace flag
$ heroku run rake assets:precompile --trace
Set the log to use STDOUT in production.rb:
config.logger = Logger.new(STDOUT)
