I couldn't get this test to work. First, I tried this.
from django.http import HttpResponse
from .models import Article
def article_list():
return HttpResponse('There are {count} articles.'.format(count=len(Article.objects.all())))
I thought about 'There are no articles.' and 'There is 1 article.', but guessed that wouldn't be necessary at such a basic level, or there would be some hints about that in the question.
from django.http import HttpResponse
from .models import Article
def article_list():
articles = Article.objects.all()
response_str = None
if len(articles) > 1:
response_str = 'There are {count} articles.'.format(count=len(articles))
else if len(articles) is 1:
response_str = 'There is 1 article.'
else:
response_str = 'There are no articles.'
return HttpResponse(response_str)
