Differences between STATIC_FILES_DIR, STATIC_ROOT and MEDIA_ROOT

Development vs. Deployment

In development, STATIC_ROOT is effectively useless, as Django automatically serves static files from each app's directory. During deployment, STATIC_ROOT becomes crucial for Nginx to locate and serve static content.

Purpose of STATIC_ROOT

STATIC_ROOT specifies the location where Django will collect and output all static files after you run manage.py collectstatic. This location should be accessible by the web server (e.g., Nginx) serving your website.

Additional Directories: STATICFILES_DIRS

STATICFILES_DIRS is an optional setting that allows you to include additional directories for collectstatic to search for static files. This is useful if you have static files outside of the default app directories.

Understanding the Issue

Based on the code you provided, it appears that you were initially having issues because the JS file was not found in the location specified by STATIC_ROOT. This is because admin.py looks for files in the admin/ subdirectory of STATICFILES_DIRS, not STATIC_ROOT.

By changing to STATICFILES_DIRS, you were able to resolve this issue because it includes the path where the JS file is located.

Summary

Setting	Purpose	Deployment
STATIC_FILES_DIR	Additional directories for static files	n/a
STATIC_ROOT	Location where static files are collected	Required
MEDIA_ROOT	Location for user-uploaded files	n/a
