Description

I have been walking through the Tutorial for Django, and upon reaching part 5 and introducing the first test case, I get this output (the directory I put the tutorial in is called 'demo')

RuntimeError: Model class demo.polls.models.Question doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

I tried adding a Meta section to the Question model, after doing some poking around in the docs.

class Question(models.Model):
    question_text = models.CharField(max_length=200)
    pub_date = models.DateTimeField('date published')
    
    class Meta:
        app_label='polls'

But then I get this:

RuntimeError: Conflicting 'question' models in application 'polls': <class 'polls.models.Question'> and <class 'demo.polls.models.Question'>.

Why was this closed? There's something missing in the tutorial, that prevents the tests from running correctly. I read that 1.9 introduces some restraints or requirements related to this app binding issue. Perhaps the tutorial has not been updated from 1.8 to accommodate that new requirement.

The tutorial works for me (and everyone else who's completed it since 1.9 was released). It looks like you made a mistake somewhere and this isn't the place to get help debugging that. Of course, if you get help and find that there is actually some problem, then by all means reopen the ticket and let us know what the problem is.
