devspaces start python-postgres

You will receive a notification when your DevSpace is ready to be used.

  1. To get inside your DevSpace, run following command
devspaces exec python-postgres

Run Demo Django Application

  1. From a new terminal, clone the demo application repository
git clone https://github.com/JumboCode/django-postgres-tutorial.git
  1. Navigate to cloned demo application directory
cd django-postgres-tutorial
  1. To synchronization code from your local machine to your DevSpace. Run following command
devspaces bind python-postgres

This will synchronize files from your current working directory to your DevSpace. It might takes some time to complete, depending on the repository size.

  1. Get inside your DevSpace by running following command
devspaces exec python-postgres

  1. Once you're inside DevSpace, you should be able see django-postgres-tutorial project files under /data directory.

  2. Install dependencies

pip install -r requirements.txt
  1. Prepare database
su postgres
psql
CREATE DATABASE djangotutorial;
CREATE USER djangotutorial WITH PASSWORD 'supersecret';
GRANT ALL PRIVILEGES ON DATABASE "djangotutorial" to djangotutorial;
\q
exit
  1. export ENV variable.
export DJANGO_SETTINGS_MODULE=django_postgres_example.settings.dev
  1. Run migrations
python3 manage.py makemigrations
python3 manage.py migrate
  1. Add .devspaces.io to ALLOWED_HOSTS variable in django_postgres_example/settings/dev.py. This can be done from your local machine as well and change will be synchronized to DevSpace. After change it looks like this
ALLOWED_HOSTS = ['localhost', '.devspaces.io']
  1. Run the demo project
python3 manage.py runserver 0.0.0.0:80

Now run following command from your local terminal devspaces info python-postgres. URL under URLs section is the public URL to your running application. Append api/sleds/ to the URL to see it is working e.g. http://python-postgres.<username>.devspaces.io:<port>/api/sleds/
