Heroku precompile संपत्ति रेल 4 एप्लिकेशन

Question

पर विफल रहा application.rb में

config.assets.initialize_on_precompile = false 

निर्धारित किया है। प्रकट-fingerprint.json (रेल 4.0 manifest.yml के बजाय manifest.json उत्पन्न करता है) जबकि नहीं पाया गया जब Heroku को धक्का दिया और Heroku precompile फिर से भागने की कोशिश की आस्तियों रन

RAILS_ENV=production bundle exec rake assets:precompile 

द्वारा सफलतापूर्वक स्थानीय स्तर पर precompiled कर रहे थे। तब मैं के रूप में त्रुटि मिली:

Running: rake assets:precompile

     Is the server running on host "127.0.0.1" and accepting

त्रुटि लगता था lib/student_module.rb में फ़ाइल है, जो config/initializers/student_init.rb में आवश्यक था की वजह से:

#lib/student_module.rb, the error pointed to this line： 
user_attributes = User.new.abttributes.keys 
#config/initializers/student_init.rb 
require 'student_module' 
ActiveRecord::Base.extend Student 

त्रुटि हो सकती है क्योंकि हेरोोकू ऐप को प्रारंभ करता है, जिसमें डेटाबेस से कनेक्शन शामिल होता है। लेकिन मैं क्योंकि मैं config.assets.initialize_on_precompile झूठी सेट की तरह

rake aborted! 
could not connect to server: Connection refused 
Is the server running on host "127.0.0.1" and accepting 
TCP/IP connections on port 5432? 

संदेश देखने के लिए नहीं होना चाहिए था और यह भी स्थानीय स्तर पर संपत्ति precompile।

इसे हल करने के लिए कोई सुझाव? धन्यवाद!

Answer 1

आपको Heroku उपयोगकर्ता-env-compile पर एक प्रयोगशाला सुविधा सक्षम करने की आवश्यकता होगी जो ऐप को संकलन समय पर पर्यावरण चर तक पहुंच प्रदान करता है।
