Q:

Static file not load in django template?

Problem is STatic file not load.

 CRM/
 |    |-- CRM/
 |    |-- next_crm/
 |    |-- static/
 |    |    +-- css/
 |    |         +-- bootstrap.min.css    <-- here
 |    +-- manage.py

This is my static variables defined in the
  next_crm/settings/settings.py file.

STATIC_ROOT = ''
STATIC_URL = '/static/'
STATICFILES_DIRS = [os.path.join(BASE_DIR, "static")]

A:

In your primary project folder (CRM, in this case) you have added the urls.py static debug lines?
urls.py
from django.conf import settings 
...
if settings.DEBUG:
   urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)

My settings.py are:
STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')
STATIC_URL = '/static/'
STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static')]
