About Incremental Progress Indicator in Management Commands
Use the ending="" parameter of stdout.write() in management commands to skip the new line symbol and allow the next write to add to the same line:
self.stdout.write(f"- {title} ", ending="")
# something with heavy processing...
self.stdout.write("✓")
For example:
# myapp/management/commands/create_fake_posts.py
from django.core.management.base import BaseCommand
class Command(BaseCommand):
help = "Creates 1000 fake posts."
def handle(self, *args, **options):
self.stdout.write("=== Creating posts ===")
for i in range(1, 1001):
self.stdout.write(f"- Post {i} ", ending="")
# create the post here...
self.stdout.write("✓")
self.stdout.write("All done!")
This will output in real time:
=== Creating posts ===
- Post 1 ✓
- Post 2 ✓
- Post 3 ✓
...
- Post 999 ✓
- Post 1000 ✓
All done!
