python_2_unicode_compatible error

Question

I've models.py as follows,

from django.contrib.auth.models import User
from django.db import models
from django.utils.encoding import python_2_unicode_compatible
from django.utils.timezone import now

@python_2_unicode_compatible
class Tag(models.Model):
    name = models.CharField(max_length=50, unique=True)

    class Meta:
            verbose_name = 'tag'
            verbose_name_plural = 'tags'
            ordering = ['name']

    def __str__(self):
            return self.name
.............  and so on

When I ran python manage.py syncdb this is the error I got:

itman@itman:~/djangoApp/mysite$ python manage.py syncdb

    from django.utils.encoding import python_2_unicode_compatible
ImportError: cannot import name python_2_unicode_compatible

I don't know why the module is not imported. I'm using Python 2.7 and Django 1.4.

Solution 1

python_2_unicode_compatible feature has only been added in Django 1.5 version.

https://docs.djangoproject.com/en/dev/ref/utils/#django.utils.encoding.python_2_unicode_compatible

Solution 2

For the latest Django 3.0.4 , and auditlog try

from six import python_2_unicode_compatible

instead of

from django.utils.six import python_2_unicode_compatible

if it is not install run the below code

pip install six

Solution 3

try

from django.utils.six import python_2_unicode_compatible

instead of

from django.utils.encoding import python_2_unicode_compatible

this works well for me in Django 1.10.6

Solution 4

I faced the same issue when I upgraded the Django version 2.x to 3.x.

This issue, I faced due to auditlog library.

First, execute the below command

pip uninstall auditlog

then

pip install auditlog3

Solution 5

I ran into this issue when I wanted to use Django for Graphite. Turns out I had Django 1.3 installed and my Graphite version was breaking with Django > 1.5, so installing the latest version of the 1.4 branch fixed the problem:

sudo pip install --upgrade 'Django<1.5'

Thanks mate! I did a django upgrade using the following: sudo apt-get install python-setuptools ; sudo easy_install --upgrade django and that solved the problem

[dannyman]

This answer doesn't actually answer the question, and I'm getting the same error with django 1.3. Upgrading to 1.6 breaks graphite, so . . . thanks but this really is not an answer.

$ python -c "import django; print(django.get_version())" $ 1.6.5 but i allso have cannot import name python_2_unicode_compatible

[Kozlov V]

it is not solved: python -c "import django; print(django.get_version())" $ 1.6.5 but i allso have cannot import name python_2_unicode_compatible

[zzarbi]

This fixed my problem, Was also trying to install Graphite

[Doogle]

works fine with django 2. Thanks for the suggestion. from django.utils.encoding import python_2_unicode_compatible this also works with django 2x

[Ashen One]

Django 3.0 changed to 'from six import python_2_unicode_compatible'

[VoidMain]

This does not solve the problem... Check out @Desperad0 answer! It worked for me.

[Abhishek Soni]

six is not available in django 3.0.2, still facing the issue

[Brendan Quinn]

@AbhishekSoni Django 3.0+ no longer supports Python 2 (docs.djangoproject.com/en/3.0/releases/3.0/…) so you can probably just remove the imports and decorators from your code and run your app under Python 3.

[Aarif]

Django 3 doesn't support python 2, what would you get out of using python_2_unicode_compatible anyways?

[Muhammad Zeeshan]

@goose how to make change in the package file? i.e python3.8/site-packages/django_messages/encoding?
