I don’t know what to do.

Can someone give a a hand. Thanks


Hi @tomasgv1

That’s a normal deprecation message. You can continue.


Thank you.
I tried to continue, but when I started the app and went to http://localhost:3000/cars to see my application, it shows a pending migration error.
it says:
“Migrations are pending. To resolve this issue, run: bin/rails db:migrate RAILS_ENV=development”

Im stuck there


You need to run rails db:migrate


I already did. But still shows a pending migration error


What happens when you run the migration? Do you get an error?
