def article_list(request): output = Article.len() return HttpResponse('There are ' + output + ' articles.')
I think I have an error in my syntax, but I am not sure. Any hints??
from django.http import HttpResponse
from .models import Article
# Write your views here
def article_list(request):
output = Article.len()
return HttpResponse('There are ' + output + ' articles.')

Article.objects.all()
This returns a queryset of all results. you can then use the len() function (not a method!) on this queryset to get the number of objects.
Also, remember to convert your length result to a string before using concatenation: str(output). Alternatively, you could use a .format() statement that auto converts output to a string for you!
Post back if you're still stuck. Good Luck!!!
