Run Scripts with Django Context

python manage.py runscript <script_name>
python manage.py runscript <script_name> --script-args arg1 arg2
python manage.py runscript <script_name> --traceback

Scripts in scripts/ directory must define a run() function.

Profiling

python manage.py runprofileserver --prof-path=/tmp/profiles
python manage.py runprofileserver --use-cprofile --prof-path=/tmp/profiles
python manage.py runprofileserver --kcachegrind --prof-path=/tmp/profiles

Notes

  • Model notation: app.ModelName (e.g., core.EmailAccount, metabox.Thread)
  • Settings wildcards: AUTH*, *_DIRS, DATABASE*
  • Commands run from project root
