blueprint css rails 3.1 help

Il mio modello css funziona sul mio computer locale, ma quando invio a heroku viene visualizzato un errore.blueprint css rails 3.1 help

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' %>

nei miei ceppi Heroku, si dice application.css isnt precompilata e penso che potrebbe essere l'errore, ma non so come aggiustarlo

Ecco miei log Heroku:

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

MODIFICA: Funziona bene durante lo sviluppo, ma ha una penalizzazione delle prestazioni poiché la compilazione viene eseguita in fase di esecuzione. Vedere la risposta seguente per una soluzione migliore

i cant ringraziarvi abbastanza. molte grazie! – John

Nessun problema. Ho iniziato a provare sia Heroku che Rails oggi, quindi potrebbe esserci un altro modo. Immagino che uno dovrebbe piuttosto compilarli in qualche modo in avanti, anche se sembrava che sarebbero stati memorizzati nella cache comunque. – Arve

Grazie per questo - http://stackoverflow.com/questions/7443536/blueprint-screen-css-isnt-precompiled - non ha funzionato. –

Un modo per risolvere questo problema è precompilare le risorse 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

al Gemfile ed eseguire bundle install.

Per i futuri lettori: questa risposta è più ideale della risposta selezionata. La soluzione ad alte prestazioni è precompilare (come dice questa risposta), non impostare compile = true. –

Devi anche dire esplicitamente a Rails di includere i file CSS Blueprint nella precompilazione. Per config/environments/production.rb, aggiungi 'config.assets.precompile + =% w (blueprint/screen.css blueprint/print.css blueprint/ie.css)'. Vedi http://stackoverflow.com/questions/7443536/blueprint-screen-css-isnt-precompiled. Quindi precompilare * per produzione * con 'RAILS_ENV = pacchetto produzione rastrellare risorse: precompilare'. Questo articolo di Heroku spiega le tre opzioni per la compilazione delle risorse: http://devcenter.heroku.com/articles/rails31_heroku_cedar. Fai tutto questo * prima * spingendo su Heroku. –

@ MarkBerry grazie! Ho avuto lo stesso problema e ora è risolto. Per quanto riguarda le immagini, devono essere aggiunte anche loro? – lanan

Ho provato a eseguire asset rake: precompilare e non riuscire a farlo funzionare. Ho il gruppo di risorse nel mio Gemfile. Ho letto da qualche parte che avrei dovuto fare in modo di precompilare l'ENV produzione:

RAILS_ENV=production bundle exec rake assets:precompile

quello non ha aiutato neanche. Ho finito con il config.assets.compile = true, che ha funzionato bene, ma mi piacerebbe che la soluzione reale funzionasse.

Non ho mai ricevuto il -----> Preparing Rails asset pipeline quando spingo a heroku che dicono che si dovrebbe ottenere.

impostare il Prova:

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 iniziando anch'io!

Ecco almeno una discussione: Rails 3.1 asset pipeline - missing files from public/assets - why isn't this the default?
