Assets not available in production

Rails
#1

I have a couple of sites that are set up in the same way (rails 3.1.3)
as far as I can tell. One of them serves up the assets (js and css)
fine in production the other doesn’t.

Both sites have this in their application.html.erb

<%= stylesheet_link_tag “application” %>
<%= javascript_include_tag “application” %>

Both sites work fine in development but when they run in production
the working site looks like this…

and the broken site looks like this…

Now I can just insert the correct lines into the application.html.erb
file and things work fine but I would like to know how this should
really be handled.

Does anyone know which configuration option I have overlooked to make
this work?

What is the exact error message you get in the log file ?

Well, I could kind of reproduce this issue by abusing the
config/environments/production.rb with this diff:

NOT ADVISED for real usage, just for testing …
(really don’t do this, it will poisen caches for the
lifetime that is set for the assets)

@@ -15,10 +15,10 @@ …::Application.configure do
config.assets.compress = true

Don’t fallback to assets pipeline if a precompiled asset is missed

  • config.assets.compile = false

  • config.assets.compile = true # false

    Generate digests for assets URLs

  • config.assets.digest = true
  • config.assets.digest = false # true

I presume the config.assets.digest would be the critical
difference here as setting it to false turns off the addition
of the digests to the pre-compiled assets.

Did you diff the config/environments/production.rb on your
2 systems?

Did you diff the public/assets/manifest.yml on the 2 systems?

HTH,

There is no actual error message, just a 404 on the
/stylesheets/application.css and /javascripts/application.js files and
no styling or javascript

I will look at the parameters that you suggest and see if I can make
sense of them

Thanks

Ok that makes sense.

Did you run the

RAILS_ENV=production bundle exec rake assets:precompile

task recently? Maybe not? It seems like:

  • the precompile task was run with digest ON
    (because the assets with digest are in /public/assets/…)
  • the current production.rb would use it with digest OFF
    (because current rendering of links is without digests)

In general, you want to use the digested versions.
