I don't understand why I am getting this error. I have tried to follow the example in the video which was: student = Student.select().order_by(Student.points.desc()).get()
from models import Challenge
all_challenges = Challenge.select()
Challenge.create(language = 'Ruby',name = 'Booleans')
sorted_challenges = all_challenges.order_by(Challenge.steps.asc()).get()

I don't remember the particular video that you are referring too, but my idea is: Shouldn't you just do something like you did in task 1/4 and then simply order_by the steps?
I didn't understand (and remember) that final .get() so I had to look at peewee's docs for get (http://peewee.readthedocs.org/en/latest/peewee/api.html#Model.get) and also I reviewed the video. From minute 6.50 it explains that .get() is added to only retrieve the first record, which is not what we want here.
Does it make sense?

3,175 PointsThanks Vittorio, see my comment after my question above. I figured out that I needed to remove get(). I thought adding a comment would prevent someone else from thinking about my original question. Perhaps there is a way to delete questions if you have solved the problem before someone else replies.

just leave the forum question as it is as it may be helpful for someone else in future.
In general the forum marks a question as "closed" or "resolved" when the user who asked the question picks the best answer to it.
Have a nice day Vittorio

3,175 PointsThanks, I did not realize that about "best answer".

3,175 PointsI just figured this one out. I should not have ended that last line with .get(). The challenge was looking for all of them, not just one.
