RSpec load_missing_constant, उम्मीद X Y परिभाषित करने के लिए (और यह करता है)

Question

जब हम

bundle exec rake spec

यह त्रुटियों को चलाने त्रुटि के साथ पर्यावरण लोड करने के दौरान:

...gems/activesupport-3.2.8/lib/active_support/dependencies.rb:503:in `load_missing_constant': Expected ...app/models/links/category.rb to define Links::Category (LoadError) 

फ़ाइल app/models/links/Category.rb वास्तव में Links::Category परिभाषित करता है। यहां तक ​​कि अजनबी है जब गार्ड और spork (मानक जिस तरह से हम परीक्षण चलाने) के तहत चल रहा है कि त्रुटि नहीं होती है:

bundle exec guard -i

टेस्ट स्वीट के रूप में इस मुद्दे के बिना उम्मीद चलाता है।

स्पार्क को rspec चलाने के लिए कॉन्फ़िगर किया गया है, इसलिए मैं थोड़ा उलझन में हूं कि rake spec क्यों चल रहा है मैन्युअल रूप से इसका कारण होगा।

मैं इसी तरह के मुद्दों जो autoload_paths को देख, और अगर यह lib और lib/** सहित था लेकिन हमारा कुछ भी autoload_paths कि मैं देख सकता हूँ के साथ फंकी कर नहीं किया गया है की जाँच करके हल किया जा करने के लिए लग रहा था देखा है। हमारे autoload_paths दिखता है इस तरह (application.rb में परिभाषित):

config.autoload_paths += %W(#{Rails.root}/app/srC#{config.root}/app/api #{Rails.root}/app/products) 

(हम नहीं बल्कि गार्ड जो हम अपने विकास मशीनों पर उपयोग करने की तुलना में परीक्षण चलाने के लिए हमारे सीआई सर्वर में bundle exec rake spec उपयोग कर रहे हैं)।

लोड हो category.rb

जोड़ा गया category.rb के शीर्ष पर puts 'Hey', और puts 'Yo' तल पर है, और जब चश्मा उत्पादन incldues चल रहा यह:

जब आपकी लेखन लिंक :: आपके स्पेक में श्रेणी, रेल शायद Links मॉड्यूल और Links::Category कक्षा ऑटो-लोड करता है।

स्पष्ट रूप से यह अजीब त्रुटि तब हो सकती है जब आप Links मॉड्यूल को सही ढंग से परिभाषित नहीं कर रहे हैं। हमने इसे कैसे डिबग किया है इसके बारे में अधिक जानकारी के लिए ऊपर दी गई टिप्पणियां देखें।
