Stable branch assets won't compile

**robbo** · June 12, 2015, 9:15pm

I was attempting to do the stable branch update so rebuilding the container and it failed to work when pre-compiling the assets. So I looked around and similar issues happen when people have plugins installed so I double checked and we have none other than the defaults.

Then I went into the container and manually run the command with --trace and this is what I got back.

Tasks: TOP => assets:precompile:css

Migrations run and everything so not sure why something would just not exist? We were previously on tests-passed but not updating, waiting for the next stable release to go stable.

This is also a multi site setup and our container.yml file could be out of date I guess.

I manually did things in the container and everything appears to be working but obviously I want a proper rebuild done.

I was hoping it had failed to compile some last not really needed asset but there was a lot of missing assets so reverted to our checked out version of tests-passed.

**neil** · June 4, 2015, 9:12pm

Hmm… so you were on tests-passed from a long time ago, updated your yml file to use the stable branch, and then did ./launcher rebuild? The db migrations happen first, so the “stylesheet_cache” table should have been found. But I think I’ve seen this kind of error before. Running rebuild a second time usually succeeded.

You should definitely compare your yml file with the latest discourse_docker yml files.

**robbo** · June 4, 2015, 9:14pm

I have had similar issues I think so made sure to try rebuild a few times. I even manually tried the migrate command more than once.

I’ll compare the yaml tomorrow and get back to you.

I am hitting a similar problem and if I understand correctly it seems this is specific to multisite configuration. For multisite the multisite:migrate occurs in the hook after_bundle_exec but the assets:precompile is trying to do its thing for each db configured. Meaning, for multisite the db migrations are actually happening after the asset compilation.

github.com

discourse/discourse/blob/9ce66038647bc4ff63167fe9c74857a01acc0875/lib/tasks/assets.rake#L76


      end


    end
  end
end


end


task 'assets:precompile:css' => 'environment' do
puts "Start compiling CSS: #{Time.zone.now}"
RailsMultisite::ConnectionManagement.each_connection do |db|
  # Heroku precompiles assets before db migration, so tables may not exist.
  # css will get precompiled during first request instead in that case.
  if ActiveRecord::Base.connection.table_exists?(ColorScheme.table_name)
    puts "Compiling css for #{db}"
    [:desktop, :mobile, :desktop_rtl, :mobile_rtl].each do |target|
      puts DiscourseStylesheets.compile(target)
    end
  end
end
puts "Done compiling CSS: #{Time.zone.now}"

At least that is my guess!

The best solution I could think of was to edit web.template.yml to perform the multisite:migrate directly prior to assets:precompile. This works for me temporarily at least.

**neil** · June 12, 2015, 2:39pm

What does your yml file look like. Does the hooks section match what’s in the howto?

**brahn** · June 12, 2015, 2:47pm

@neil yes, I made sure it was the same and up to date as well as confirming that it was synced with any changes to the samples. As soon as I moved the multisite:migrate from my yml into web.template.yml it works fine.

**robbo** · June 23, 2015, 4:02am

We use multisite as well. I have made the same changes above but the other way around. I moved the compile toafter the multisite:migrate in my own container and deleted it from the web.template.yml.

And with those changes, update working. Thanks.

Can you update the multisite howto to reflect it is wiki
