I recently pulled a repo from GitHub to get a local copy on my machine. The backend uses Django, and I was working on updating some models. Since I changed some models I wanted to run ./manage.py makemigrations. At first there was an issue with python2 vs python3, so I changed the #!/usr/bin/env python to #!/usr/bin/env python3. Then when I ran makemigrations, I get this:
File "./manage.py", line 10, in <module>

ImportError: No module named 'autofixture'
Looking a bit further, I found out that this is because my settings.py file has autofixture, bootstrap3, and formtools in INSTALLED_APPS, but somehow my machine doesn't have those. I've tried to pip install all of them but the names autofixture, bootstrap3, and formtools aren't found in pip.
They are in pip, albeit not in those names; they are django-autofixture, django-bootstrap3 and django-formtools respectively.
So you can install them by typing:
pip install django-autofixture django-bootstrap3 django-formtools
Edit: Use pip3 instead of pip when using python3
pip3 install django-autofixture django-bootstrap3 django-formtools

I have a Django app running on an old CentOS 7 box, and to have my own python3 environment there I'm using venv and pip. Today I rebuilt my environment, and suddenly, I had an ssl related backtrace.

_lib.Cryptography_HAS_TLSEXT_HOSTNAME, "SNI not available"
AttributeError: module 'lib' has no attribute 'Cryptography_HAS_TLSEXT_HOSTNAME'
The versions of my modules are set in a requirements.txt file, which did not change. I was running pyOpenSSL 19.0.0, with Python 3.6. I upgraded to pyOpenSSL 20.0.0 and the problem went away, but I am confused as to how this could happen unless the 19.0.0 version on PyPI was changed, as I've used fixed versions of this module for some time now.
Can anyone explain what happened here? I'd like to avoid anything similar in the future. Thanks.
The root cause for this issue is the latest cryptography-3.3 package which was released 20 hours ago; unfortunately, the pyopenssl-19 has a weird requirement (cryptography >=2.3) hence the pip install automatically upgraded the cryptography to 3.3.
We have both pip and pip3 installed. So the following sequence is what fixed it for me:
sudo apt update; pip install -U cryptography; sudo apt remove python3-openssl -y; sudo apt autoremove; pip3 install -U cryptography;
I think I found it. I didn't have the cryptography module in my requirements.txt, so it was upgraded to the latest version without upgrading pyOpenSSL which was in my requirements.txt file. Seems like some kind of dependency should have prevented this, but I'm updating my requirements.txt to include everything now.
There's a new cryptography 3.3.1 which fixes the issue
I used the Django Rest Framework cookiecutter available here to scaffold a project. I've made no changes aside from setting up a virtualenv, installing requirements, and running pip install graphene_django. However, when I add graphene_django to the INSTALLED_APPS I receive the following error when attempting to run the server:
ModuleNotFoundError: No module named graphene_django
Any ideas why?

The issue seems be related to Docker (or more specifically, me being unfamiliar with Docker). Running the docker-compose up --build command solved the issue. Hopefully, that helps someone else!

ModuleNotFoundError: No module named 'registration'
I am using Manjaro Linux and have installed the packages python-django and python-django-extensions with pacman.
How can I resolve this error so that I can run the web app? I have not changed after cloning the aforementioned repo.
You need to install the project dependencies.
run pip install -r requirements.txt in tango_with_django_19/code to install them.
Then migrate and runserver
You're missing django-registration-redux package. It is specified in requirements.txt file as necessary to run project. You could install it via pip install -r requirements.txt
if you get the error after pip install django-registration-redux you can try easy_install django-registration-redux it worked for me.

ImportError: No module named 'django-watson'
I think it has installed in env but i can't find where is django-watson
I want remove django-watson clearly
please somebody help me
Make sure you have removed it from INSTALLED_APPS in settings.py and that you have removed all imports related to it inside your project.
As said, you have to remove django-watson from your installed apps. But that was the original mistake: to install watson, you have to add watson to your INSTALLED_APPS, not django-watson. This is well explained in the documentation:
Install django-watson using pip: pip install django-watson.
Add 'watson' to your INSTALLED_APPS setting.
I have been trying to set up a new django project locally with cookiecutter-django. I have followed the docs but I keep getting into errors when trying to run python manage.py migrate.

I don't really know what I am doing wrong while setting up the project, I'd appreciate if you check the steps I took and help me find out what is missing.
Steps taken to setup the project with cookiecutter-django:
pip, virtualenv, PostrgreSQL already installed
pip install cookiecutter
cookiecutter https://github.com/pydanny/cookiecutter-django
Answer cookiecutter questions
Creating virtualenv - virtualenv -p /usr/bin/python3 venv
Activiting virtualenv - source venv/bin/activate/
cd intoprojectfolder
Docs say sudo ./install_os_dependencies.sh install but ./install_os_dependencies.sh is not in projectroot, file found in utility/
cd utility
sudo ./install_os_dependencies.sh install
pip install -r requirements/local.txt
Setting up db in postgresql:
sudo su - postgres
psql
CREATE DATABASE myproject;
CREATE USER myprojectuser WITH PASSWORD 'password';
GRANT ALL PRIVILEGES ON DATABASE myproject TO myprojectuser;
\q
Return tu project root
mv env.example .env
export DATABASE_URL=postgres://myprojectuser:myprojectuserdbpassword#127.0.0.1:5432/myproject
python manage.py migrate
After that is when I get the traceback, what could be going wrong? The docs show no more information, the migration should work.
Cookiecutter uses the slug of the project name as the name for the development db you are to use. You are expected to create the database yourself.
from your stacktrace here is the line giving you the problem from your settings.py file:
File "/home/ubuntu/lasbrisas_project/django_condominios/config/settings/common.py", line 102, in <module>'default': env.db('DATABASE_URL', default='postgres:///django_condominios'),
It expects to find a database named django_condominios.
You can fix this by running
createdb django_condominios
and you should be good run your migrations.
