Rails 3.2.6 routing error for fonts

Question

I have a Rails 3.2.6 based application using web-app-theme gem. After deploying in production I seeing following errors in /var/log/apache2/error.log.

[Wed Jul 18 23:00:14 2012] [error] [client 50.53.58.188] Premature end of script headers: fonts, referer: https://xxx.xxx.xx.xxx

.....

I have placed the mentioned file museosans_500-webfont.svg in app/assets/fonts/ directory. But why I am still this error. I also see similar error for other assets like /assets/fonts/museosans_500-webfont.ttf, etc.

Any feedback is much appreciated. Thanks.

Try add fonts dir to assets path in environment.rb:

config.assets.enabled = true
config.assets.paths << "#{Rails.root}/app/assets/fonts"

Meduza Thanks, but after adding these entries to the environment.rb I got phusion exceptions for line containing "config". My application.rb file already has "config.assets.enabled = true" entry. So I added your second entry to the application.rb but got the same (orginal) error. Should I add these entries to the production.rb or test.rb file? – Atarang Jul 19 '12 at 09:11
Sorry, I have this line in application.rb! – Meduza Jul 19 '12 at 13:13
Look at this, maybe it help http://stackoverflow.com/questions/7673988/rails-bundler-precompile-vs-lazy-compile – Meduza Jul 19 '12 at 13:19
Meduza, thanks again but it didn't fix the issue. I'm still getting the same errors. – Atarang Jul 20 '12 at 04:16

The url in your CSS / HTML seems to be wrong:

/assets/fonts/museosans_500-webfont.svg

You should change that to:

/assets/museosans_500-webfont.svg

But keep the file on the app/assets/fonts directory.

I ran into the same problem when integrating the Katex library.

The issue is that Rails' Asset Pipeline compiles the assets into the public/assets directory without keeping the fonts or images or javascript directories.

So when you're looking for /assets/fonts/museosans_500-webfont.svg, it doesn't exist, that font has been compiled to /assets/museosans_500-webfont.svg.

To solve this you have two options:

Update the path in the CSS or JS:

/assets/fonts/museosans_500-webfont.svg

becomes

/assets/museosans_500-webfont.svg
Put the fonts in a fonts subdirectory:

If you don't want to (or can't) update the CSS or JS (e.g. it's a minified third party library), then you can use the following method to ensure that there is a public/assets/fonts directory that contains all your fonts.

Simply put your font(s) in the following path:

/assets/fonts/fonts/museosans_500-webfont.svg

Now your public/assets directory will contain a fonts directory and your GET request will be happy.
