Can't run migrations when setting up a project with cookiecutter-django

Question

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.

Traceback (most recent call last):

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

1. pip install cookiecutter
2. cookiecutter https://github.com/pydanny/cookiecutter-django
3. Answer cookiecutter questions
4. Creating virtualenv - virtualenv -p /usr/bin/python3 venv
5. Activiting virtualenv - source venv/bin/activate/
6. cd intoprojectfolder
7. 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
8. pip install -r requirements/local.txt
9. 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
10. Return tu project root
11. mv env.example .env
12. export DATABASE_URL=postgres://myprojectuser:myprojectuserdbpassword@127.0.0.1:5432/myproject
13. 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.

Answer 1

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.
