Blueprint CSS Rails 3.1 Hilfe

Question

Mein Blaupause CSS funktioniert auf meiner lokalen Maschine, aber wenn ich nach Heroku drücke, bekomme ich einen Fehler.

Ich habe Blueprint in meinem gespeichert app/assets/stylesheets folder Und hier sind die Stylesheet -Tags, die ich verwende:

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

In meinen Heroku -Protokollen heißt es, dass die Anwendung nicht vorgekommen ist, und ich denke, das könnte der Fehler sein, aber ich weiß nicht, wie ich es beheben soll.

Hier sind meine Heroku -Protokolle:

Answer 1

Ich hatte einfach das gleiche Problem. Ich habe es gelöst, indem ich gesetzt wurde config.assets.compile = true in config/environments/production.rb

Bearbeiten: Dies funktioniert bei der Entwicklung gut, hat jedoch eine Leistungsstrafe, da die Zusammenstellung in der Laufzeit durchgeführt wird. Eine bessere Lösung finden Sie in der Antwort unten

Answer 2

Eine Möglichkeit, dies zu beheben, besteht darin, die Vermögenswerte durch Laufen vorzubereiten rake assets:precompile. Sie müssen eine JavaScript -Laufzeit dafür einfügen, indem Sie hinzufügen

# 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

zum Gemfile und Renn bundle install.

Answer 3

Versuchen Sie, Ihre festzulegen:

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

in config/environments/production.rb

Ich bin sicher, jemand mit mehr Erfahrung als ich kann uns sagen, warum alle CSS-Dateien nicht standardmäßig vorkompiliert werden. Ich fange gerade erst an!

Hier ist mindestens eine Diskussion:Rails 3.1 Asset Pipeline - Fehlende Dateien von öffentlichen/assosen - Warum ist das nicht der Standard?

Answer 4

Ich habe versucht, Rake Assets: Precompile zu leiten und konnte es nicht zum Laufen bringen. Ich habe die Vermögensgruppe in meiner GemFile. Ich habe irgendwo gelesen, dass ich sicherstellen sollte, dass ich die Produktionsumwelt vorkompilien:

RAILS_ENV=production bundle exec rake assets:precompile

Das hat auch nicht geholfen. Am Ende habe ich die config.assets.compile = true gemacht, was gut funktioniert hat, aber ich würde gerne die wirkliche Lösung zum Laufen bringen.

Ich verstehe nie das -----> Preparing Rails asset pipeline Wenn man nach Heroku drängt, sollte man sagen, dass man bekommen sollte.
