Unable to run Migrations

[sbshah97]

Hi, I tried setting up the project and set up the virtual environment and activated it as well. However when I try to run migrations I get the following errors.

Traceback (most recent call last):

I did try to Google this up and came upon this link

Tried changing the appstore/settings/base.py file from

from django.core.urlresolvers import reverse_lazy

to

from django.urls import reverse_lazy

but got the following error.

Let me know how we can solve this error!

I'm extremely sorry that I didn't follow up on this. Are you still planning to work on this?

[sbshah97]

I would love to if you can get me started here! Maybe small contributions once in a while! Is the main repo link here itself or do we have another main repository somewhere else?

[abhijithanilkumar]

Hi @salman-bhai, This is the main repository. Sorry for the delay in response 😓 Btw, this error is a virtualenv issue, I think. Once you setup virtualenv, before running migrations, you have to goto src/appstore/settings/ and run cp local.sample.env local.env. I missed this step in the readme, will update it.

Hi, I did the above steps and fixed the import errors (Django 2.0 related) shown in all the files. Now I'm facing another issue and am still unable to run migrate.

Hi @rohit-mp,
We do not officially support Django 2.0 yet, can you try using a virtualenv with the mentioned requirements and see if it is working?

[rohit-mp]

I checked again and pip install fails for few tools
Failed to build django-admin-bootstrapped django-authtools easy-thumbnails django-haystack

All of them had the same error as this one below

Running setup.py bdist_wheel for easy-thumbnails ... error
  Complete output from command /home/rohit/ns3/ns-3-AppStore/appstore/bin/python3 -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-5l896nre/easy-thumbnails/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" bdist_wheel -d /tmp/tmpx7b_l05opip-wheel- --python-tag cp36:

  ----------------------------------------
  Failed building wheel for easy-thumbnails
  Running setup.py clean for easy-thumbnails

Running pip install as sudo installed those tools but with a different command:

Running setup.py install for django-admin-bootstrapped ... done
  Running setup.py install for django-authtools ... done
  Running setup.py install for easy-thumbnails ... done
  Running setup.py install for django-haystack ... done
  Running setup.py install for python-openid ... done

I'm not sure what bdist_wheel was doing earlier.
But along with these being installed, it gave another error:

django-haystack 2.6.1 has requirement Django<1.11, but you'll have django 1.11.18 which is incompatible.
django-admin-bootstrapped 2.5.7 has requirement Django<1.9,>=1.8, but you'll have django 1.11.18 which is incompatible.

The Django version mentioned in base.txt is >=1.9 while installing, so I guess the django part needs to be completely updated?

[abhijithanilkumar]

Can you confirm whether you are using a virtualenv? Looks like you have multiple django versions in your system, causing an error. Please work with a virtualenv, and run the installation and post any error that you find.

[rohit-mp]

Yes, I was running a virtualenv but I think I might've upgraded the django version the first time I encountered these issues. I'll check it and let you know.
