Heroku font assets not working

Placed fonts in app/assets/fonts

Added 

Add the fonts path
config.assets.paths << Rails.root.join('app', 'assets', 'fonts')

Precompile additional assets
config.assets.precompile += %w( .svg .eot .woff .ttf )

in production.rb and development.rb

Fonts linked in css like:

@font-face {
  font-family: 'Icomoon';
  src:url('/assets/icomoon.eot');
  src:url('/assets/icomoon.eot?#iefix') format('embedded-opentype'),
    url('/assets/icomoon.svg#icomoon') format('svg'),
    url('/assets/icomoon.woff') format('woff'),
    url('/assets/icomoon.ttf') format('truetype');
  font-weight: normal;
  font-style: normal;
}

Seems to work in development. But in HEROKU is does not seem to work. It cannot find /assets/icomoon.eot .

The solution in this link does not seem to work

There are two ways to solve this issue.

  1. You can directly put your font files in public directory and add the path e.g /fonts/font-name in the CSS file
  2. Add the line Rails.application.config.assets.compile = true in config/initializers/assets.rb file

After trying all the methods above, none worked for me but this is how I fixed my font problem. If the fonts work in development mode then simply do 

config.assets.compile = true

in

config\environments\production.rb

You don't actually have to change the precompile regex or asset path. Try to run rake assets:precompile in production mode before committing to Heroku.

rake assets:precompile RAILS_ENV=production

and make sure to reference your assets in css files using asset_path helper method.

like:

src: font-url('<%= asset_path("foundation-icons.eot")%>');

Rails 4

# config/application.rb
config.assets.paths << Rails.root.join("app", "assets", "fonts")
config.assets.precompile += %w(.svg .eot .woff .ttf)

# app/assets/stylesheets/foundation-icons.css.scss
@font-face {
  font-family: "foundation-icons";
  src: asset-url("foundation-icons.eot");
  src: asset-url("foundation-icons.eot?#iefix") format("embedded-opentype"),
       asset-url("foundation-icons.woff") format("woff"),
       asset-url("foundation-icons.ttf") format("truetype"),
       asset-url("foundation-icons.svg#fontcustom") format("svg");
  font-weight: normal;
  font-style: normal;
}

  1. Rename your .css file to .css.erb
  2. Replace all the url('/assets/icomoon.eot') with url(<%= asset_path 'icomoon.eot' %>), etc.

You can achieve the same result by converting your css file to SASS/SCSS and using font-url() helper instead of url().

I've tried that with Rails 4 and it works even without the bits you've added to production.rb/application.rb.

In light of the comments received on this answer (and the unnecessary downvotes) I've amended my answer as follows:

It seems Rails has now created a way to handle fonts in the assets folder. It's called font-path and works like this:

If you add a custom font to your /assets/fonts folder, you can use the font-path helper to access the files within. This can then be used in your stylesheets & other assets using the font-path helper:

|-app/
|---assets/
|-----fonts/
|-----images/
|-----javascripts/
|-----stylesheets/

@font-face {
  font-family:'icofonts';
  src:font-url('icofonts.eot');
  src:font-url('icofonts.eot?#iefix') format('embedded-opentype'),

  ...
}

This works for precompiled assets (which Heroku does anyway), and static assets. If you want the pre-Rails 4 way of achieving this, please refer to my answer below:

We've got fonts working on Heroku here: http://firststop.herokuapp.com (it's in demo still)

Here is our CSS for it:

#assets/application.css
/*-- Akagi Font --*/
@font-face {
    font-family: 'akagi';
    src: url('fonts/akagi-th-webfont.eot'),
    src: url('fonts/akagi-th-webfont.eot?#iefix') format('embedded-opentype'),
         url('fonts/akagi-th-webfont.woff') format('woff'),
         url('fonts/akagi-th-webfont.ttf') format('truetype'),
         url('fonts/akagi-th-webfont.svg#akagithin') format('svg');
    font-weight: 300;
    font-style: normal;

}
@font-face {
    font-family: 'akagi';
    src: url('fonts/akagi-bk-webfont.eot');
    src: url('fonts/akagi-bk-webfont.eot?#iefix') format('embedded-opentype'),
         url('fonts/akagi-bk-webfont.woff') format('woff'),
         url('fonts/akagi-bk-webfont.ttf') format('truetype'),
         url('fonts/akagi-bk-webfont.svg#akagibook') format('svg');
    font-weight: 400;
    font-style: normal;

}
@font-face {
    font-family: 'akagi';
    src: url('fonts/akagi-sb-webfont.eot');
    src: url('fonts/akagi-sb-webfont.eot?#iefix') format('embedded-opentype'),
         url('fonts/akagi-sb-webfont.woff') format('woff'),
         url('fonts/akagi-sb-webfont.ttf') format('truetype'),
         url('fonts/akagi-sb-webfont.svg#akagisemibold') format('svg');
    font-weight: 500;
    font-style: normal;

}

We put our fonts into the /stylesheets/fonts folder

We just do the standard precompile fonts stuff to get all CSS working on Heroku, and it works. I suspect your paths are not correct. Maybe try moving your fonts directory into your /assets/stylesheets folder :)

I solved the problem by using a combination of all the answers and comments. My example uses the Foundation Icon Fonts.

In your application.rb file add the following:

config.assets.precompile << /\.(?:svg|eot|woff|ttf)$/

Rename your application.css file to application.css.scss and use the font-url and asset-path directives:

@font-face {
  font-family: "foundation-icons";
  src: font-url( asset-path("foundation-icons.eot") );
  src: font-url( asset-path("foundation-icons.eot?#iefix") ) format("embedded-opentype"),
       font-url( asset-path("foundation-icons.woff") ) format("woff"),
       font-url( asset-path("foundation-icons.ttf") ) format("truetype"),
       font-url( asset-path("foundation-icons.svg#fontcustom") ) format("svg");
  font-weight: normal;
  font-style: normal;
}

Assets like fonts will work on development but not production if you are using regular old css to locate your assets rather than the asset pipeline helpers. Rails 4 added breaking changes to the asset pipeline to encourage people to use it properly, and not use the old css method of referencing assets.

To resolve this, you need to use the new asset pipeline helpers to point to the fingerprinted, cached versions of your fonts. Rather than url (which does not use the asset pipeline), you need to use font-url (which does use it). To do this, you may have to use Sass or embed ERB in your stylesheet.

Example (using SCSS):

@font-face {
  font-family: 'Icomoon';
  src: font-url("/assets/icomoon.eot");
  src: font-url("/assets/icomoon.eot?#iefix") format("embedded-opentype"), font-url("/assets/icomoon.svg#icomoon") format("svg"), font-url("/assets/icomoon.woff") format("woff"), font-url("/assets/icomoon.ttf") format("truetype");
  font-weight: normal;
  font-style: normal;
}

You don't need to include the /assets/fonts/ directory in config.assets.paths. According to documentation all directories included in app/assets, lib/assets or vendor/assets are automatically loaded.

http://guides.rubyonrails.org/asset_pipeline.html#asset-organization

Pipeline assets can be placed inside an application in one of three locations: app/assets, lib/assets or vendor/assets.

[...]

Besides the standard assets/* paths, additional (fully qualified) paths can be added to the pipeline in config/application.rb.

config.assets.paths << Rails.root.join("lib", "videoplayer", "flash")

Try to run Rails.application.class.config.assets.paths in console and you'll see an array of all directories inside /assets. if you add another directory and restart the console it will be automatically included inside the array and the content will be served as assets.

You don't even need config.assets.precompile += %w( .svg .eot .woff .ttf ) because all non-js-css files are already included through the default matcher Proc.

http://guides.rubyonrails.org/asset_pipeline.html#precompiling-assets

The default matcher for compiling files includes application.js, application.css and all non-JS/CSS files (this will include all image assets automatically):

[ Proc.new { |path| !%w(.js .css).include?(File.extname(path)) }, /application.(css|js)$/ ]

Try to only add the fonts directory in app/assets/ leaving all config as default and deploy your app on heroku.

Actually, I just tried the solution proposed in this comment, and it worked perfectly. Seems you only have to change the regex for the precompile instruction in order for Heroku to correctly find the asset.

i.e. change config.assets.precompile += %w( .svg .eot .woff .ttf ) to config.assets.precompile << /\.(?:svg|eot|woff|ttf)$/.

Edit: It might also be necessary to add RAILS_ENV=production when you run the assets:precompile rake task, as per Heroku's docs.

Try removing /assets/ from all of your font paths. 

@font-face {
  font-family: 'Icomoon';
  src:url('icomoon.eot');
  src:url('icomoon.eot?#iefix') format('embedded-opentype'),
    url('icomoon.svg#icomoon') format('svg'),
    url('icomoon.woff') format('woff'),
    url('icomoon.ttf') format('truetype');
  font-weight: normal;
  font-style: normal;
}

Also try removing scaffolds.css if it's in assets/stylesheets.
