@angelmoya, thanks for your interest and efforts!
It seems that it doesn't work (or, am I doing it wrongly?):
copier copy --vcs-ref patch-1 https://github.com/angelmoya/full-stack-fastapi-template.git my_project --trust
When it asks me to specify password for the PostgreSQL database I enter ch.
It doesn't give me any errors and I can see POSTGRES_PASSWORD=ch in .env

@YuriiMotov @angelmoya The inline validation didn’t trigger because Jinja in a single-line YAML string can be ignored by Copier. I think it's best to use a multi-line block like the above to make it work.
