• django-neomodel 0.1.1

Quickstart

First create an sandbox database, make sure to select Paradise Papers by ICIJ under Pre-Built Data, copy the credentials: username, password and bolt URL, you are going to need that later.

# Clone this repository
git clone https://github.com/neo4j-examples/paradise-papers-django

# Go into the repository
cd paradise-papers-django 

# active your [virtual environment](https://docs.python.org/3/tutorial/venv.html) and install your dependencies
cd paradise_papers_search
python -m venv venv
source venv/bin/activate
pip install -r ../requirements.txt

# Run the app
export DATABASE_URL=bolt://<username>:<password>@<address>:7687 # update with the credentials from your sandbox database.
python manage.py runserver --settings=paradise_papers_search.settings.dev

Registering Models in the Admin

In paradise_papers_search/fetch_api/admin, add the models you would like to explore using the admin:

from django.contrib import admin as dj_admin
from django_neomodel import admin as neo_admin

from .models import Entity

class EntityAdmin(dj_admin.ModelAdmin):
    list_display = ("name",)
neo_admin.register(Entity, EntityAdmin)

Create the admin superuser:

./manage.py migrate
./manage.py createsuperuser

Run the app!

python manage.py runserver --settings=paradise_papers_search.settings.dev

Start searching at http://127.0.0.1:8000/

View the admin at http://127.0.0.1:8000/admin

While testing locally you may want to do export ALLOWED_HOST=*

Quick Heroku Deployment with Neo4j Sandbox

Create an sandbox database, make sure to select Paradise Papers by ICIJ under Pre-Built Data. copy the database's username, password, and bolt URL.

Create a Heroku app, (for example, paradise-papers) Go to the app's settings and add the following config vars: ALLOWED_HOST : paradise-papers.herokuapp.com DATABASE_URL: the credentials from your sandbox database in the following format bolt://user:password@ip:port

Clone the repository and navigate into the directory, add Heroku as a remote, and push to Heroku:

git clone [email protected]:neo4j-examples/paradise-papers-django.git
cd paradise-papers-django
git remote add heroku https://git.heroku.com/paradise-papers.git
git push heroku master
