If im not mistaken, this could be caused by circular import

check inside /app/ init .py that from app import models appears as the last line, not at the top

@tosaiprakash I suggest you compare your files against mine to find the problem, it's really hard for me to figure out what's wrong with just the one file that you shared. You can use the link at the top of the article to download the files that correspond to the chapter you are reading, that should help you figure out the problem.
