It should be said that yes, that is normal. p.choice_set.all() is a list of 
Choice objects, not a list of strings attributes for each object.

You're right that it's not a very readable result, which is why the 
__unicode__ method exists to add a more user-friendly representation of 
that object for console/Django admin display. Still, don't lose sight of 
the fact that p.choice_set.all() is actually always returning a collection 
of Choice objects.

That happens because you seem to hsve missed or decided to skip the
instructions located right above the interactive section you are at:

The one about adding __unicode__ methods to the models and saving the
models.py file.

Did you add an __unicode__ method to Choice class? That's how you get the 
pretty representations of objects.

You probably need a p.save() after creating the choices to actually place
them in the database...otherwise I can see why the ORM is confused since
choices_set causes a database hit and you are expecting objects that don't
technically exist yet...

Polls tutorial receive object not object representation

[Sayth Renshaw]

Hi

Just seeking a little clarification.

In the Polls tutorial we get this section.

>>> p = Poll.objects.get(pk=1)
# Display any choices from the related object set -- none so far.>>> 
p.choice_set.all()[]
# Create three choices.>>> p.choice_set.create(choice_text='Not much', 
votes=0)>>> p.choice_set.create(choice_text='The sky', 
votes=0)>>> c = p.choice_set.create(choice_text='Just hacking 
again', votes=0)
# Choice objects have API access to their related Poll objects.>>> c.poll
# And vice versa: Poll objects get access to Choice objects.>>> 
p.choice_set.all()[, , ]

Now the only thing is that when I call p.choice_set.all() I don't get the 
representation 'The sky' or 'Just Hacking again' . I receive choice object 
itself. Is this normal?

In [14]: c = p.choice_set.create(choice_text='Just Hacking again', votes=0)

In [15]: c.poll
Out[15]: 

In [16]: p.choice_set.all()
Out[16]: [, , , ]

Thanks 

Sayth
