How did you setup your Django dev environment? - django

Question

I'm trying to setup a local Django dev environment using VMs enabled with Vagrant but I'm not sure what's the best way to go about it.
I did a git clone for Django files from production server and installed all the modules that the production server has on my local VM. I wanted to avoid installing a database on my local VM but ran into some problems with the sessions. The local machine is using SESSION_COOKIE_DOMAIN='localhost' and the production is using SESSION_COOKIE_DOMAIN='.mydomain.com' so that creates some confusion.
Not to mention that on the setting.py on my dev environment I had to change IPs to point to the public IP address of the database (thus poking a hole on the security) while my production settings.py is using the local IPs so I ended up using different settings.py files.
I can continue experimenting with new methods but I really have to get going with the project and I'm pretty sure some people had this figured out already.
So how did you setup your Django dev environment?

Answer 1

I have a public repo on GitHub available here:
https://github.com/FlipperPA/djangovagrant
Instructions from the README.md:
Django / Python / MySQL
This is a Vagrant project for Django development.
This does not yet support berkshelf or librarian; all necessary repos are included in 'cookbooks'.
Prerequisites, all platforms:
Virtualbox https://www.virtualbox.org/wiki/Downloads
Vagrant http://downloads.vagrantup.com/
Pre-requisites, Windows only:
git-bash
ruby rvm
Fairly easy to get it running:
vagrant up
vagrant ssh djangovm
** (Note: You are now in the Virtualbox VM as superuser vagrant)
sudo apt-get install python-pip
** (Note: PIP is a Python package manager)
sudo apt-get install python-mysqldb
sudo pip install django
Starting a Django project:
django-admin.py startproject django_project
cd django_project
python manage.py runserver [::]:8000
The VM is configured to use port forwarding. If everything went right, you should be able to access the running server through the browser on your computer running the virtual machine at this url:
http://localhost:8001/

Answer 2

there are a few django Apps that I've seen to manage this but I always prefer the following in my settings.py as the number of different configs are usually minimal
SITE_TYPE = environ.get( 'SITE_TYPE', 'DEV' )
if SITE_TYPE == 'LIVE':
DEBUG = False
DEFAULT_HOST = ''
else:
DEBUG = True
DEFAULT_HOST = '50.56.82.194'
EMAIL_HOST = DEFAULT_HOST

I can recommend this repository.
You can modify it to support Django projects.
Vagrantfile updates:
config.vm.define "web1", primary: true do |web1_config|
web1_config.ssh.forward_agent = true
# Create a private network, which allows host-only access to the machine
web1_config.vm.network "private_network", ip: "192.168.11.10"
web1_config.vm.hostname = "web1.#{domain}"
web1_config.vm.provision "shell", path: "provisioners/shell/python.setup.sh"
web1_config.vm.provision "shell", path: "provisioners/shell/application.setup.sh"
end
Then add a provisioners/shell/application.setup.sh file with the following content:
#!/bin/bash
local_user=vagrant
if [ ! -n "$(grep "^bitbucket.org " /home/$local_user/.ssh/known_hosts)" ]; then
ssh-keyscan bitbucket.org >> ~/.ssh/known_hosts 2>/dev/null;
fi
if [[ ! -d "/home/$local_user/app" ]]; then
git clone git#bitbucket.org:czerasz/sample-django-app.git /home/$local_user/app
chown -R $local_user:$local_user /home/$local_user/app
su - $local_user -c "source /usr/local/bin/virtualenvwrapper.sh && mkvirtualenv sample-django-app-env && workon sample-django-app-env && pip install -r /home/$local_user/app/requirements.txt"
fi
Change the repository address (git#bitbucket.org:czerasz/sample-django-app.git) and make also sure that you have a requirements.txt in the root of your git repository. Run vagrant up.
Vagrant will start two machines:
web1 with your django project
db1 with a PoestgreSQL database
If you still have issues add the following to your Vagrantfile:
web1_config.ssh.private_key_path = [ '~/.vagrant.d/insecure_private_key', '~/.ssh/bitbucket' ]
And execute this command on your host (the machine where you run vagrant):
ssh-add ~/.ssh/bitbucket
The ~/.ssh/bitbucket is the ssh private key which you use for bitbucket. It can be ~/.ssh/id_rsa or something different depending how you configured it.
