search_challenges

Why did it not find the right number of challenges?

Here is my code:

def search_challenges(name, language): return Challenge.select().where(Challenge.name == name, Challenge.language == language)

Thank you

crud.py 
from models import Challenge


def create_challenge(name, language, steps=1):
    Challenge.create(name=name,
                     language=language,
                     steps=steps)

def search_challenges(name, language):
  return Challenge.select().where(Challenge.name == name, Challenge.language == language)

Challenge.name should be checked to see if it contains name, unlike Challenge.language wich should be checked for equality .

I don't understand the challenge's statement "You don't need boolean and ...". So how else are you to "just put both conditions in your where()"?

Anyway, if you ignore the confusing advice and replace your comma with and, it passes the challenge. :stuck_out_tongue_winking_eye:

def search_challenges(name, language):
  return Challenge.select().where(Challenge.name == name and Challenge.language == language)

I had same experience, did not work but added the "and" and challenged passed.
