My search_challenge function doesn't work

I thought I was adding the function correctly, but im getting a syntax error. Am i missing something else?

from models import Challenge

def create_challenge(name, language, steps=1):

def search_challenges():
    challenge = challenge.where(Challenge.content.contains(name, language)

1 Answer

Your code (for reference):

def search_challenges():
    challenge = challenge.where(Challenge.content.contains(name, language)

Two basic things first:

  1. Your function needs to have two parameters: name and language.
  2. Your function needs to return a value, which is all Challenges that meet the criteria.

Now for the specifics:

  1. You don't have to create a variable called challenge and assign the results of the query to it; you can just return the query results.
  2. The c in challenge.where should be capitalized.
  3. You should have a select() in between Challenge and where.
  4. Challenge.name must contain the name argument, but Challenge.language must equal the language argument.

My solution:

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