__unicode__() addition not working in basic poll application.

[maaz muqri]

Hi,
____________________________________
class Poll(models.Model):
# ...
def __unicode__(self):
return self.question

class Choice(models.Model):
# ...
def __unicode__(self):
return self.choice
____________________________________


after adding the above code also I am not able to retrieve the
question by the command:

I am getting this

>>>Poll.objects.all()
[<Poll: Poll object>]


instead of this

>>>Poll.objects.all()
[<Poll: What's up?>]

I think you are getting the poll object back. You need to specify the method for your model class(es)

def __unicode__(self):

        return "%s %s %s" % (self.poll_name)

Did you restart the interpreter after adding the code?

Can it be necessary to recreate a model?

That is wrong, you have a placeholder for three args and just pass one
to the string formatting. Moreover, you don't even need that here.

def __unicode__(self):
return self.poll_name

Probably a fast-reply kind of error, but that could lead the original
poster to even get more issues than helping him to solve it.

Sorry about that. It is indeed not right. I will take care of this from next time onwards.

What do you get when you do:

print unicode(Poll.objects.all()[0])

?

Roman

[maaz muqri]

im just getting "Poll object" as output

[Roman Klesel]

hmm... strange...

the __unicode__ thing is nothing django-specific. It works in plain
python as well:

It's supposed to work like this:

>>> class TestClass(object):
... def __unicode__(self):
... return "unicode"
... def __repr__(self):
... return "buh"
... def __str__(self):
... return "str"
...
>>> o=TestClass()
>>> o
buh
>>> print o
str
>>> print unicode(o)
unicode
>>>

Hi, i found this post when try to solve same problem: my trouble was a
"spaces" in models.py.
in your first message it seems to be ok, but you must really check
spaces in your class describe.

[Kyle Latham]

Hello,

I am having the same problem while working through the tutorial. have
searched these forums and tried everything that was recommended. My
spacing is good also - I checked that. I am still getting the same
output:

>>> Poll.objects.all()
[<Poll: Poll object>]

Any ideas on how to fix my issue?

What do you get when you try:

>>> p = Poll.objects.all()[0]
>>> p
>>> type(p)
>>> dir(p)

Try this too:

>>> p = Poll.objects.all()
>>> for x in p:
. . . print x (indent this line four spaces, hit return key once)
. . . (hit return key again)

Does any of that help?

Good luck!

Cheers,

You should be fore-warned that Django does not officially support Python 3.

https://docs.djangoproject.com/en/1.4/releases/1.4/#python-compatibility

If you are using the trunk or 1.5 version of django, then that has
experimental support for python 3.

https://docs.djangoproject.com/en/dev/faq/install/#can-i-use-django-with-python-3

If you are trying to learn how to use django, I would strongly
recommend against using an in development version of django, or using
experimental support for python 3, since these can introduce strange
side effects like the one you've noticed that are not fully
documented. OTOH, if you know django and want to make the next release
even better, or improve on that experimental support, dive right in.

Cheers

Tom

[Colin Keenan]

Thanks for the advice. It's true that I'm just learning django, and because I wanted to use python3, I installed via the most up-to-date development source code.  My experience with development versions of stuff has actually been better than the fully supported versions of the same product for some reason. So, I'll be continuing on this path. It's strange that people were experiencing this error over a year ago and didn't mention if they were using python3. Anyone searching on this error in the future will be glad to see the correct answer here if they are using python3.

[Colin Keenan]

By the way, I just checked django.VERSION and it's (1, 6, 0, 'alpha', 0)

So, since version 1.6 is supposed to fully support python 3, I should be fine. Obviously, being 'alpha' means I'll run into trouble, but I'll keep checking out new versions as I learn so by the time 1.6 is really out, I'll be all set.

Django 1.5 isn't even released yet. I've no idea how you've got onto "1.6 alpha", but I doubt it will be released any time soon - it's probably at least 9 months away. You should stick to the released versions rather than running from trunk, and that means Python 2 for now.

[Russell Keith-Magee]

Filling in the blanks here -- If you download Django's trunk branch, it currently reports as 1.6 alpha. When we cut the 1.5 alpha, we created a separate branch for 1.5 development, so that trunk can remain in a live "commit anything" state, rather than our historical "trunk feature freeze" state. 

So, in theory, trunk can currently contain features that won't be included in 1.5; however, in practice, the core team is focussing primarily on the 1.5 release branch, in preparation for the 1.5 beta and final releases.

Just restart the python interactive Shell... that should solve your problem

I was having the same problem my django version was 1.3.1 and python 2.7. There was indentation problem with my code after correcting it my problem was solved.

[Brachamul]

Could someone post what the entire "models.py" file should look like at this point?
I don't think I have indendation problems, but I'm new to both Python & Django, so I can't be sure.
Using Python 2.7.5 and Django 1.4.

show us your code, and someone might show you where it is wrong, but the tutorial is pretty clear on what you have to do.

I have same problem with Django 1.6.1 and Python 2.7.5. I tried to restart interactive interpreter by exit() but it still doesn't work :(

Following the tutorial, for Python3 we use _str_ but I am using Python 2.7.5 so I use _unicode_.

Can anyone help to point out the problem and solution? Thanks!

[trojactory]

Juan,

Are you entering double underscores like '__unicode__'?

Cheers,

Arun

[Kai Ren]

Just type exit()

then re-enter the shell, it will work.

No, just single underscore

[Juan Hu]

As I mentioned, I tried this but it doesn't work for me. Is this the python unicode problem? I tried unicode(Poll.objects.all()) and it returns the same

[shmengie]

trojactory has the right idea.

__unicode__ has two underscores on either side of _ _ unicode _ _

If you don't spell __unicode__ with two underscores on both sides, you are not overriding the default method __unicode__

You are getting the default output for __unicode__ instead of the expected.

Hi I am having the same issue:

I am using Python 2.7, and Django 1.6.

Here is my code for models.py:

import datetime

from django.db import models

from django.utils import timezone

# Create your models here.

class Poll(models.Model):

    question = models.CharField(max_length=200)

def __unicode__(self):

return self.question

pub_date = models.DateTimeField('date published')

def was_published_recently(self):

return self.pub_date >= timezone.now() - datetime.timedelta(days=1)

class Choice(models.Model):

    poll = models.ForeignKey(Poll)

    choice_text = models.CharField(max_length=200)

    votes = models.IntegerField(default=0)

def __unicode__(self):

return self.choice_text

I have restarted the shell and this is what I get as a result:

bash-3.2$ python manage.py shell

Python 2.7.6 (default, Dec 19 2013, 06:00:47) 

[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin

Type "help", "copyright", "credits" or "license" for more information.

(InteractiveConsole)

>>> from polls.models import Poll, Choice

>>> Poll.objects.all()

[<Poll: Poll object>, <Poll: Poll object>]

>>> exit()

bash-3.2$ python manage.py shell

Python 2.7.6 (default, Dec 19 2013, 06:00:47)

Type "help", "copyright", "credits" or "license" for more information.

(InteractiveConsole)

>>> from polls.models import Poll, Choice

>>> Poll.objects.all()

[<Poll: Poll object>, <Poll: Poll object>]

>>> 

Any help would be great...

Cheers,

Steve

[Shai Efrati]

i wonder if it is just the formatting of the email, but i think you missed spaces before your def. def are hierarchically under classes, so it should be:

import datetime

from django.db import models

from django.utils import timezone

# Create your models here.

class Poll(models.Model):

    question = models.CharField(max_length=200)

    def __unicode__(self):
return self.question

    pub_date = models.DateTimeField('date published')

    def was_published_recently(self):
          return self.pub_date >= timezone.now() - datetime.timedelta(days=1)

class Choice(models.Model):

    poll = models.ForeignKey(Poll)

    choice_text = models.CharField(max_length=200)

    votes = models.IntegerField(default=0)

    def __unicode__(self):

return self.choice_text

Good luck!

Shai.

Thankyou! so much...!

It was because i had tabs instead of 4 spaces for the indents.

So basically it was an indentation error but it didn't say that in the console.

I think this will fix a lot of other peoples problems if they are using tabs instead of spaces for indentations.

Cheers.

[Matheus Henrique Oliveira]

Hi Steve.

The __unicode__ method must be within the model class. I took your code and applied the fix.
