Rails 4 Assets Precompilation with multiple manifest files

ruby-on-rails-4

I have a rails 4 application.

I have 3 sets of manifest files in order to seperate out logic for my app.

These files are

application.js
backoffice.js
pos.js

application.css
backoffice.css
pos.css

In my layout files, I reference these assets using the associated javascript_link_tags

I have added the following to my production.rb file (in order to include these files in the precompilation of assets):

config.assets.precompile += %w( backoffice.js pos.js pos.css backoffice.css )

I then run rake assets:precompile, but it is not picking up the additional files.
It only compiles the application.js and application.css manifests.

In production.rb also, I have:

config.serve_static_assets = true
config.assets.compile = false

Anyone any ideas?

thanks

If you copy this line

config.assets.precompile += %w( backoffice.js pos.js pos.css backoffice.css )

to config/application.rb (Rails 4.0) (instead of config/environments/production.rb) it will work.

I've got a tip from here: Rails 4 assets.precompile

As suggested in the comments, in Rails 4.2 you should write above line in config/initializers/assets.rb

Update (07/22/2013): Heroku now supplies a different gem to precompile assets.

group :production do
  gem 'rails_12factor'
end

Ruby-on-rails – font glyphicons not working with bootstrap 3 and rails 4

If you're using bootstrap-sass gem, follow my setup below. If not give it a try, it's the easiest bootstrap setup that I've used.

By the way I'm currently using rails Versions 4.1.6 and 4.1.8

Two gems

gem 'bootstrap-sass'
gem 'autoprefixer-rails'

Your Application.js should look like this below (turbolinks optional)

  /app/assets/javascripts/application.js

//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require bootstrap-sprockets
//= require_tree .

Style sheet should have these two imports

/app/assets/stylesheets/application.scss

@import "bootstrap-sprockets"
@import "bootstrap"

if this setup doesn't work for you try font-path http://guides.rubyonrails.org/asset_pipeline.html#coding-links-to-assets

section 2.3.2 css and sass

so your code would go from:

url('/assets/glyphicons-halflings-regular.eot');

to font-path('glyphicons-halflings-regular.eot');
