ฉันกำลังพยายามตั้งค่าไฟล์การตั้งค่าหลายไฟล์ (การพัฒนา, การผลิต, .. ) ที่มีการตั้งค่าพื้นฐานบางอย่าง ไม่สามารถประสบความสำเร็จได้ เมื่อฉันพยายามเรียกใช้./manage.py runserverฉันได้รับข้อผิดพลาดต่อไปนี้:
(cb)clime@den /srv/www/cb $ ./manage.py runserver
ImproperlyConfigured: The SECRET_KEY setting must not be empty.
นี่คือโมดูลการตั้งค่าของฉัน:

ถ้าฉันเพิ่มfrom base import *เข้าไป/srv/www/cb/cb/settings/__init__.py(ซึ่งว่างเปล่า) มันจะเริ่มทำงานอย่างน่าอัศจรรย์ แต่ฉันไม่เข้าใจว่าทำไม ใคร ๆ ก็อธิบายให้ฉันฟังได้ว่าเกิดอะไรขึ้นที่นี่? มันต้องเป็นมายากลโมดูลหลามแน่ ๆ
แก้ไข:ทุกอย่างจะเริ่มทำงานเช่นกันถ้าฉันลบบรรทัดนี้ออกจาก base.py
django.template.loader.add_to_builtins('web.templatetags.cb_tags')
ถ้าฉันลบบรรทัดนี้ออกจาก web.templatetags.cb_tags ก็จะเริ่มทำงาน:
from endless_pagination.templatetags import endless
ฉันเดาว่ามันเป็นเพราะในที่สุดมันก็นำไปสู่
from django.conf import settings
PER_PAGE = getattr(settings, 'ENDLESS_PAGINATION_PER_PAGE', 10)
ดังนั้นมันจึงสร้างสิ่งที่เป็นวงกลมแปลก ๆ และจบเกม
