As I´m using the Asset Packager plugin to minify and merge Javascript in a project that I currently work on, some additional tasks needed to be added to generate the CSS from LESS CSS before merging into packages. You simply need the following tasks for it to work or you´ll hit dependency problems.
# lib/tasks/less.rake
namespace :less do
desc 'Updates stylesheets if necessary from their LESS CSS templates.'
task :update => :environment do
Less::More.clean
Less::More.parse if Less::More.page_cache?
end
end
# config/deploy.rb
namespace :less do
desc 'Updates the stylesheets generated by LESS CSS'
task :update do
run "cd #{release_path} && rake less:update RAILS_ENV=production"
end
end
after "deploy:update_code", "deploy:create_asset_packages"
before "deploy:create_asset_packages", "less:update"
Remember to have the LESS gem installed on the server. The LESS CSS Rails plugin called “more” is used in the above example.
