progetto css rotaie 3.1 aiuto

Question

Il mio progetto css funziona sulla mia macchina locale, ma quando spingo a Heroku ottengo un errore.

Ho progetto memorizzati nel mio app/assets/stylesheets folder e qui ci sono i tag foglio di stile che sto usando:

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

Nel mio log Heroku, si dice application.css isnt precompilato e penso che potrebbe essere l'errore, ma non so come risolvere il problema.

Ecco miei log Heroku:

Answer 1

Ho appena avuto lo stesso problema. Ho risolto impostando config.assets.compile = true in config/environments/production.rb

EDIT: questo funziona bene, mentre in via di sviluppo, ma ha una riduzione delle prestazioni, come la compilazione viene eseguita in fase di esecuzione. Vedere la risposta qui sotto per una soluzione migliore

Answer 2

Un modo per risolvere questo problema è di precompilare il patrimonio eseguendo rake assets:precompile. Si deve includere un runtime JavaScript per questo con l'aggiunta di

# 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

per il Gemfile ed eseguire bundle install.

Answer 3

Prova a impostare il vostro:

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

in config/environments/production.rb

Sono sicuro che qualcuno con più esperienza di me ci può dire il motivo per cui tutti i file CSS non sono pre-compilati come standard. Sto solo cominciando appena fuori troppo!

Ecco almeno una discussione: Rails 3.1 gasdotto patrimoniale - file mancanti da pubblici / attività - perché non è questo il default

?

Answer 4

Ho provato a eseguire le attività rastrello: precompilare e non sono riuscito a farlo funzionare. Ho il gruppo attivo nel mio Gemfile. Ho letto da qualche parte che avrei dovuto fare in modo di precompilare l'ENV di produzione:

RAILS_ENV=production bundle exec rake assets:precompile

Che non ha aiutato neanche. Ho finito per fare la config.assets.compile = true, che ha funzionato bene, ma mi piacerebbe ottenere la soluzione vera al lavoro.

Non ho mai ottenere il -----> Preparing Rails asset pipeline quando si spinge a Heroku che dicono si dovrebbe ottenere.
