Django अनुप्रयोग अनुचित रूप से कॉन्फ़िगर - एप्लिकेशन मॉड्यूल एकाधिक फ़ाइल व्यवस्था स्थिति

Question

मुझे लगता है कि मैं वास्तव में ऊपर कुछ खराब कर दिया है है। मेरी Django एप्लिकेशन (उत्पादन एक) को मैं एक प्रमुख अद्यतन धक्का दिया और कर रहा हूँ कि जब भी मैं अपने डोमेन के लिए जाने की कोशिश एक "आंतरिक सर्वर त्रुटि" मिलता है। मैं अपने uwsgi लॉग में एक त्रुटि हो रही है:

मैं क्या The app module <module 'ledger' (namespace)> has multiple filesystem locations (['./ledger', '/home/ubuntu/web/app/ledger']); you must configure this app with an AppConfig subclass with a 'path' class attribute. चल रहा है द्वारा पता नहीं है।

अन्त में जब मैं कोड के पिछले संस्करण चेकआउट करने के लिए प्रयास करते हैं,:

यहाँ मेरी settings.py फ़ाइल है। मुझे एक ही समस्या है।

संपादित करें - जोड़ने uwsgi.conf फ़ाइल

# file: /etc/init/ppuwsgi.conf 
description "uWSGI server for PennyPledge" 

start on runlevel [2345] 
stop on runlevel [!2345] 

respawn 
exec /usr/local/bin/uwsgi --home /home/ubuntu/web/app/ --socket /home/ubuntu/web/ppuwsgi.sock --chmod-socket=666 --module=pennypledge.wsgi --pythonpath /home/ubuntu/web/ -H /home/ubuntu/.virtualenvs/pennypledge --logto /home/ubuntu/web/logs/uwsgi.log --chdir=/home/ubuntu/web/app --chmod-socket=666 

हालांकि, मैं क्यों यह uwsgi की गलती होगी पता नहीं है, के रूप में मैं केवल Django परियोजना अपडेट किया गया।

Answer 1

समस्या यह है कि मैं एक __init__.py फ़ाइल नष्ट किया गया। जाहिर है, django उन्हें यह जानने के लिए उपयोग करता है कि कौन से फ़ोल्डर्स पैकेज हैं, इसलिए वे बहुत महत्वपूर्ण हैं।

Answer 2

त्रुटि अपने ledger अनुप्रयोग में है। क्या यह एक कस्टम ऐप है?

Django स्रोत कोड से, त्रुटि, त्वरित सुधार के रूप में से _path_from_module(app_module)

# Filesystem path to the application directory eg. 
    # u'/usr/lib/python2.7/dist-packages/django/contrib/admin'. Unicode on 
    # Python 2 and a str on Python 3. 
    if not hasattr(self, 'path'): 
     self.path = self._path_from_module(app_module) 

आता है अगर यह आपके अनुप्रयोग है, तो आप एक AppConfig उपवर्ग एक वैध path विशेषता है कि इसके साथ कॉन्फ़िगर कर सकते हैं, जो होगा निष्पादन से बग को रोकें। मैं इसे और आगे देख रहा हूं।

यदि ledger आपका ऐप नहीं है, और आपने इसे pip या किसी अन्य माध्यम से अपडेट किया है, तो यह बताता है कि पुराने संस्करण की जांच करने से समस्या ठीक नहीं होती है। उस ऐप का पुराना संस्करण अपने भंडार से प्राप्त करने का प्रयास करें (यदि लागू हो) और एक बग रिपोर्ट सबमिट करें।
