Rails 4 ve Ruby 2.0 uygulaması ile nasıl canlı yüklenir?

Question

Rails 4 + Ruby 2.0 projesinde metin editöründe .scss veya .erb dosyasını düzenlerseniz, tarayıcıdaki canlı değişiklikleri görmek istiyorum.

Guard ve Guard-live-reload'ı denedim, ancak şu hatayı atıyor.

Answer 1

i livereload ile çalışmak nasıl budur:

1.) sizin Gemfile yılında gem

alın:

group :development do 
    gem 'guard-livereload', require: false 
end 

2.)guard init livereload, hangisi Uygulamanızın kökünde bir Guardfile oluşturur.

3.) senin Guardfile diğer bekçi eklentileri onlar livereload altında kalmak çalıştırırsanız o, (bu gibi sadece Guard-Livereload görünmelidir açılması.)

guard 'livereload' do 
    watch(%r{app/views/.+\.(erb)$}) 
    watch(%r{app/helpers/.+\.rb}) 
    watch(%r{public/.+\.(css|js|html)}) 
    watch(%r{config/locales/.+\.yml}) 
    watch(%r{(app|vendor)(/assets/\w+/(.+\.(css|js|html|png|jpg))).*}) { |m| "/assets/#{m[3]}" } 
end 

4.) senin sunucuyu yeniden başlatın) Chrome Web Store

5'ten Livereload Chrome Uygulamasını alın ve ayrı bir sekme açmak ve tip->guard

Diğer en aynı soruya denk olabilecek için yoğun yazdım (Guard Sekmesi'ndeki Bağlı Tarayıcı)

sizin Tarayıcıda

6.) livereload düğmeye basmak ve bunu bağlanmalıdır. Özel durumunuz için # 3'u okuyun. Korumanızı aç ve önce Livereload'ın arandığından emin ol.

git SSL ile çalışırken Railscast #264 Guard

, livereload oldukça iyi böyle değil izleyin.

Rack-Livereload, SSL sorunlarının üstesinden gelmek için projenize ekleyebileceğiniz temiz bir küçük parçadır. Gem bir parça veya Rack middleware ekler ve temel olarak mevcut (ve SSL etkin) Rails sunucusundan javascript'i sunmak için livereload uygulamasına bağlanır.
