css plan rails 3.1 aide

Question

Mon css plan fonctionne sur ma machine locale, mais quand je pousse à heroku je reçois une erreur.

J'ai plan stocké dans mon app/assets/stylesheets folder et voici les balises de feuille de style que je utilise:

<%= stylesheet_link_tag    "application" %>
<%= stylesheet_link_tag 'blueprint/screen', :media => 'screen' %>
<%= stylesheet_link_tag 'blueprint/print',  :media => 'print' %>

Dans mes journaux de Heroku, il est dit application.css isnt précompilés et je pense que cela pourrait être l'erreur, mais je ne sais pas comment le résoudre.

Voici mes journaux de Heroku:

Answer 1

Je viens d'avoir le même problème. Je l'ai résolu en mettant config.assets.compile = true dans config/environments/production.rb

EDIT: Cela fonctionne très bien, tout en développant, mais a une pénalité de performance que la compilation est réalisée en exécution. Voir la réponse ci-dessous pour une meilleure solution

Answer 2

Une façon de résoudre ce problème est de précompiler les actifs en exécutant rake assets:precompile. Vous devez inclure un moteur d'exécution javascript pour cela en ajoutant

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'therubyracer'
  gem 'sass-rails', "  ~> 3.1.0"
  gem 'coffee-rails', "~> 3.1.0"a
  gem 'uglifier'
end

à la Gemfile et exécuter bundle install.

Answer 3

Essayez de régler votre:

config.assets.precompile += %w( blueprint/screen.css blueprint/print.css )

config/environments/production.rb

Je suis sûr que quelqu'un avec plus d'expérience que moi ne peut nous dire pourquoi tous les fichiers CSS ne sont pas pré-compilés en standard. Je ne fait que commencer trop!

Voici au moins une discussion: Rails 3.1 pipeline d'actifs - les fichiers manquants du public / actifs - pourquoi est-ce pas la valeur par défaut

?

Answer 4

J'ai essayé de courir des actifs de rake: precompile et ne pouvait pas le faire au travail. Je le groupe actif dans mon Gemfile. Je lis quelque part que je vous assurer de l'précompiler env production:

RAILS_ENV=production bundle exec rake assets:precompile

Cela n'a pas aidé non plus. J'ai fini par faire la config.assets.compile = true, ce qui a bien fonctionné, mais j'aimerais obtenir la véritable solution au travail.

Je ne me l'-----> Preparing Rails asset pipeline en poussant à heroku qu'ils disent on devrait obtenir.
