Re: how to display a foreign key image of an object in an object_list view/template?

There was a typo: products = Product.objects.all() for product in products: product.image = product.productimages_set.first() Other than that, it should work. You could try this in the django shell, just to verify the reverse name of the relationship. from your_app.models import * product=

Re: Use one correspondig database user for each application user

Thank you for your answer. Yes, I use one database user since several years, and I guess it will be that way the next years. Nevertheless I think it is good to talk about things like this from time to time. Regards, Thomas Am Dienstag, 11. Juli 2017 12:11:59 UTC+2 schrieb Antonis Christofide

Use one correspondig database user for each application user

I guess most applications have exactly one database user. Why not use one database for each application user? Example: User "foo" in my web application has a corresponding database user "foo". This way you could use row level security from the database. PostgreSQL has a lot of interesting feat
