Rails assets don't get updated

问题:

I have a Rails 3.1 app and for some reason when I change CSS, the changes don't show up. I did bundle exec rake assets:precompile and it helped once, but now I am stuck with the old CSS no matter what.

回答1:

As your assets are now precompiled you need to clean them with the following

bundle exec RAILS_ENV=development rake rails_group=assets assets:clean

回答2:

You might want to try rake assets:clean and then rake assets:precompile

回答3:

For my production environment I had to combine a few of the above steps to get my assets recompiled.

First I had to do:

rake assets:clean

Making sure I was in the right environment

Then I needed to delete the public/assets directory that the precompile creates (or just the file that you need to fix, application-<hash>.css for example)

Then finally re-run

rake assets:precompile

And restart my apache server (I use passenger with apache, not tested with nginx)

For me is was just deleting compiled css/js files from public directory.

It turned out that other dev put it there and didn't let know anyone.

回答5:

What worked for me in rails, chrome, mac :

1 - In terminal :

rake assets:clean

2 - In Sublime text or in Finder :

Delete the "Public > Assets" folder

3 - In terminal launch localhost server :

rails s

4 - In chrome :

http://localhost:3000/

5 - Reload chrome clearing cache if relevant :

cmd + shift + R

You should now be able to update your css files and see immediate changes on your localhost just reloading the page

DO NOT RUN "rake assets:precompile" in terminal because it will recreate the folder "assets" in the "public" folder and you won't be able to see updates of your css files directly in your localhost

In case any future Googlers find this thread: I had the same problem in the test environment of a Rails 4.2.8 application. None of the above solutions worked. Setting config.serve_static_files = false in config/environments/test.rb solved it.

Bear in mind that this is a temporary fix as it causes all files in the public folder to no longer be served (including 404.html, favicon.ico, robots.txt, etc).
