Hello,

I have been struggling to resolve this problem.

I am following the setup -


Which was not bad till I got this this point.

Initial data


python manage.py oscar_populate_countries

I was able to install the -
pip install pycountry

with success.
I am using mysql -installed the adapter-
DATABASES = { 'default': { #'ENGINE': 'django.db.backends.sqlite3', #'NAME': os.path.join(BASE_DIR, 'db.sqlite3'), # Ends with "postgresql_psycopg2", "mysql", "sqlite3" or "oracle". "ENGINE": "django.db.backends.mysql", # DB name or path to database file if using sqlite3. "NAME": "mydatabase", # Not used with sqlite3. "USER": "muuser", # Not used with sqlite3. "PASSWORD": "mypassword", # Set to empty string for localhost. Not used with sqlite3. "HOST": "localhost", # Set to empty string for default. Not used with sqlite3. "PORT": "myportnumber", 'ATOMIC_REQUESTS': True, } }



Other settings that might raise an interest -

# Full filesystem path to the project.
PROJECT_APP_PATH
= os.path.dirname(os.path.abspath(__file__))
PROJECT_APP
= os.path.basename(PROJECT_APP_PATH)
PROJECT_ROOT
= BASE_DIR = os.path.dirname(PROJECT_APP_PATH)

# Static files (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/1.9/howto/static-files/

STATIC_URL
= '/static/'

# Absolute path to the directory static files should be collected to.
# Don't put anything in this directory yourself; store your static files
# in apps' "static/" subdirectories and in STATICFILES_DIRS.
# Example: "/home/media/media.lawrence.com/static/"
STATIC_ROOT
= os.path.join(PROJECT_ROOT, STATIC_URL.strip("/"))

# URL that handles the media served from MEDIA_ROOT. Make sure to use a
# trailing slash.
# Examples: "http://media.lawrence.com/media/", "http://example.com/media/"
MEDIA_URL
= STATIC_URL + "media/"

HAYSTACK_CONNECTIONS

'ENGINE': 'haystack.backends.simple_backend.SimpleEngine',
 
'URL': 'http://127.0.0.1:8983/solr',

},
}


i have installed south -

I have removed a few things I do not want made in public but hope the main problem is explained well.


I also this the following to see if the error would be resolve but still got it.


pip install -U --force-reinstall django

So far I have uninstalled django-oscar and trying to make a start again.


I downloaded the following -


https://github.com/django-oscar/django-oscar-stores


and


https://github.com/django-oscar/django-oscar



Don't know if I can play around it to make sense of it.


Any reason why I am having this error ?




Thanking you.

Coincidentally I ran into this yesterday.  I hacked site-packages/oscar/management/commands/oscar_populate_countried.py to reflect:

        countries = [
            Country(
                iso_3166_1_a2=country.alpha_2, # note the underscore
                iso_3166_1_a3=country.alpha_3, # note the underscore
                iso_3166_1_numeric=country.numeric,
                printable_name=country.name,
                name=getattr(country, 'official_name', ''),
                is_shipping_country=options['is_shipping'])
            for country in pycountry.countries]

Perhaps a new version of pycountries came out recently with new attribute names?

Hope this get you unstuck.

Thanks,
Jim

What you are suggesting to hack is in bold above. and so why this error?  It's no difference to yours.

I did file an issue a couple of days ago. And they seem to be looking at it -



and so what I'm doing wrong again?


Thank you so much for looking into this and sharing.

Hello,

Sorry, it didn't load all the messages I was sending here is the 

= [

           
Country(

                iso_3166_1_a2
=country.alpha2,

                iso_3166_1_a3

                iso_3166_1_numeric
=country.numeric,


                printable_name
=country.name,

                name
=getattr(country, 'official_name', ''),

                is_shipping_country
=options['is_shipping'])

           
for country in pycountry.countries]





       
Country.objects.bulk_create(countries)




       
self.stdout.write("Successfully added %s countries." % len(countries))



There's no difference between your code and mine above so what is going on?

Regards

Hello,

I did file an issue with the django-oscar team because, I do believe it's a bug.


And the team seems to be doing something about it. I believe


meaning I may have to wait for the pycountry.py release?

Hello Jim,

I took a look at your code below again, 

 iso_3166_1_a2=country.alpha_2, # note the underscore
 iso_3166_1_a3=country.alpha_3, # note the underscore


and yes I hacked it. corrected. 
I have another error but that's another story.

Thank you.


Regards
