Django-based API to serve URLid + graph database

django-urlid-graph

Django-based API to serve URLid + graph database. This repository hosts the app code and also a project structure so it's easier to develop - only the urlid_graph folder is packaged before going to PyPI.

Installation and configuration

1. Add "urlid_graph" to your INSTALLED_APPS setting like this:

INSTALLED_APPS = [
    ...
    "urlid_graph",
]

2. Change database configurations (this example uses python-decouple):

DATABASE_URL = config("DATABASE_URL")  # must be set
GRAPH_DATABASE_URL = config("GRAPH_DATABASE_URL")  # must be set
graph_config = config("GRAPH_DATABASE_URL", cast=db_url)
GRAPH_DATABASE = graph_config["NAME"]  # must be set
DATABASES = {
    "default": config("DATABASE_URL", cast=db_url),
    GRAPH_DATABASE: graph_config,  # must set this way
}
DATABASE_ROUTERS = ["urlid_graph.db_router.RelationAndGraphDBRouter"]

3. Configure Django caching system (used to store ElementConfig labels):

CACHES = {
    "default": {
        "BACKEND": "django.core.cache.backends.locmem.LocMemCache",
        "TIMEOUT": 24 * 3600,
        "MAX_ENTRIES": 1024,
    }
}

4. Include the urlid_graph URLconf in your project's urls.py like this:

    path('v1/', include("urlid_graph.urls")),

5. Run python manage.py migrate to create the needed models, triggers etc.

6. Populate the database:

# you may want to add entities to urlid_graph_entity model
python manage.py import_config data/config.csv  # must create this file before
python manage.py import_config data/config.csv  # must create this file before
python manage.py import_objects appname Model file.csv.xz  # must create model
python manage.py import_relationships relname file.csv.xz

Importing data

python manage.py import_objects appname Model file.csv[.gz|.xz]
python manage.py import_relationship relname file.csv[.gz|.xz]
