Context:

In ruby on rails project, I would like to live compile the assets on production. But, newly added CSS is not applied to the production. I found there is a setting config.assets.compile = false, which means the production is using precompiled assets.

However, after setting config.assets.compile = true, it is still not working. This post is to navigate this situation.

Trial:

Clean the precompiled assets RAILS_ENV=production rake assets:clean It is still not working, because there is still public/assets in the project directory.

Solution:

Another command: RAILS_ENV=production rake assets:clobber The whole folder public/assets is removed. Now the assets are removed. It is now live compile now. Congrats!

Questions to explore:

• What is the difference between RAILS_ENV=production rake assets:clean and RAILS_ENV=production rake assets:clobber?
  • clean -> only clean the old precompiled assets
  • clobber -> clean all of the precompiled assets

Reference

• live compile
