python - Error when adding new field to existing model in Django on Elastic Beanstalk using RDS -

i'm getting error when try add new field existing model in django. it's hosted on elastic beanstalk using mysql rds database.

here's error when try access model containing new field:

(1054, "unknown column 'existing_model.new_field' in 'field list'")

is there better way treat migrations in django on eb? here's .config file:

container_commands:   01_makemigrations:     command: "source /opt/python/run/venv/bin/activate && python manage.py makemigrations --noinput"     leader_only: true   02_migrate:     command: "source /opt/python/run/venv/bin/activate && python manage.py migrate --noinput"     leader_only: true   03_createsu:     command: "source /opt/python/run/venv/bin/activate && python manage.py createsu"     leader_only: true   04_collectstatic:     command: "source /opt/python/run/venv/bin/activate && python manage.py collectstatic --noinput" 

any help? thanks!

turns out had run python manage.py makemigrations locally before eb deploy. way, migration files created , when migrate ran on eb instance, knows how change database accordingly.

my .config file now:

container_commands:   01_migrate:     command: "source /opt/python/run/venv/bin/activate && python manage.py migrate --noinput"     leader_only: true   02_createsu:     command: "source /opt/python/run/venv/bin/activate && python manage.py createsu"     leader_only: true   03_collectstatic:     command: "source /opt/python/run/venv/bin/activate && python manage.py collectstatic --noinput"
