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.
Error Traceback.

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.

I am using Django for the first time but have used PostgreSQL previously. I am trying to follow the official Django tutorial to set up with a database. I have followed everything but I get an error when using the command "python manage.py migrate" that psycopg2 is not found even though I have it
installed.Traceback (most recent call last):

I am using the settings as mentioned in the Django tutorial:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'DatabaseName',
'USER': 'UserName',
'PASSWORD': 'Userpassword',
'HOST': '127.0.0.1',
'PORT': '5432',
}
}
I have confirmed that I have the necessary packages installed and in the same location :
pip freeze:
Django==4.1.3
psycopg2==2.9.5
psycopg2-binary==2.9.5
pip show Django/psycopg2/psycopg2-binary:
Django : Location: /opt/homebrew/lib/python3.10/site-packages
Psycopg2: Location: /opt/homebrew/lib/python3.10/site-packages
psycopg2-binary: Location: /opt/homebrew/lib/python3.10/site-packages
It's seems like you use system python for running your migrations. Error traceback contains following path of python binary: "/Users/alexanderverheecke/Library/Python/3.9/...", however in pip show command your python path is "/opt/homebrew/lib/python3.10/".
Actually I don't understand how it's even possible, because first one looks like Windows path and the second one like Linux...
Anyway. Try something of this and run migrate command again:
activate/deactivate virtual environment if you use it
change your OS to the correct one
run pip install again
Make shure command which python(for Linux), gcm python (for Windows) returns the same python path as pip show.
I have this new remote job, where I had to clone all the code from a repository, and I have to make an export of the database from MySQL hosted in RDS.
The first problem is that when I set up the configuration to start the app, it raise an error telling me this:
Run Configuration Error: Broken configuration due to unavailable plugin or invalid configuration data.
The other thing is that I already have the data dumped and set up in my local storage (the app works this way, is no longer using AWS Cloud) but when I try to do an python manage.py migrate , this error comes up...

ModuleNotFoundError: No module named 'admin'
First, django-liststyle is a dependency in your project, so make sure it has been installed.
py -m pip install django-liststyle
Second, make sure to add that package to INSTALLED_APPS:
INSTALLED_APPS = {
...
'liststyle',
...
'django.contrib.admin',
...
}
Third, I think the error you are getting is because of the way you are importing ListStyleAdminMixin. This should be the correct way to import it:
from liststyle.admin import ListStyleAdminMixin
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!

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 am trying to install readthedocs in local system (Ubuntu 14.04 ) in python3 virtual env from the instructions given in this link
When I ran pip3 install -r requirements.txt , I got an error for Distutils2 . I removed that dependency as the distutils2 is no longer supported and assumed setuptools would suffice.
Running this command python manage.py migrate gave the below error :

I understand from the above stacktrace that the code is in python2 and so print statement is different in python3 .
Does this mean that I have to install readthedocs in python2 virtualenv ?
Can't we host the docs of python3 projects in readthedocs in-house server ?
The read the docs code does not support Python 3 yet. The installation instructions explicitly say to use Python 2.7:
First, obtain Python 2.7 and virtualenv
However, it should still be possible to use your read the docs installation to host docs for Python 3 projects, since the instructions then say:
If you plan to import Python 3 project to your RTD then you’ll need to install Python 3 with virtualenv in your system as well.
