Last coding challenge

Can't figure out what the error means. Also, can't figure out what's wrong with the code! Thanks for the help.

queries.py 
from models import Challenge

all_challenges = Challenge.select()

Challenge.create(name="Booleans",language="Ruby")

sorted_challenges = all_challenges.order_by(Challenge.steps).get()

Forgot to add what the error message was: "Challenge object is not iterable".

Hey Rwiddhi Chakraborty,

You do not need to call get() when you use order_by(Challenges.steps). The last line of your code should look like this:

sorted_challenges = all_challenges.order_by(Challenge.steps)

Okay!

But I still don't get the meaning of error message and its context. Could you explain that to me?
