Re: Problem to connect to database only when run "migrate"

Hi Heron,

To make sure you are talking to your database, 
in your project and in your command line, type
 python manage.py shell 
then import your model

If for example you have prodApp and model Product
from prodApp.models import Product
prd = Product.objects.all()
print(prd) 
Please checkout ORM (  https://docs.djangoproject.com/en/3.2/topics/db/queries/ )operations, if you can talk to the database via ORM and see the data in your database, then everything is setup correctly and you need to look into the settings etc

I hope this helps

Kind regards
Aziz Meknassi
