A Django app to integrate Apache Superset dashboards into a Django application
Project description
django-superset-integration
django-superset-integration is a Django app to integration Apache Superset dashboards into a Django application.
Quick start
- Add
django_superset_integrationto yourINSTALLED_APPSsetting like this:
INSTALLED_APPS = [
...,
"django_superset_integration",
...,
]
- Include the superset-integration URLconf in your project
urls.pylike this:
path("superset_integration/", include("django_superset_integration.urls")),
- You will need a cryptography Fernet key, so you need to install cryptography:
pip install cryptography
- Generate a Fernet key in a python terminal:
from cryptography.fernet import Fernet
FERNET_KEY = Fernet.generate_key()
-
The result is a bytestring like
b'jozEHFGLKJHEFUIHEZ4'. Copy ONLY the content of the string, not the b nor the quotation marks -
In your env variables, create a variable
FERNET_KEYwith the copied content as value -
Add a variable
ENCRYPTION_KEYin yoursettings.pyreferencing your env variableFERNET_KEY:
ENCRYPTION_KEY = os.environ.get("FERNET_KEY", "").encode()
- By default, all dashboard data will be displayed. You can override this by creating your own filtering function and adding it in your
settings.py:
RLS_FUNCTION = "my_app.my_module.create_rls_clause"
Your function must take a parameter user and return a SQL rls clause like this : [{"clause": "1=1"}]
(where you replace 1=1 by the clause you want).
See Superset documentation for more information
-
Make sure that your Superset instance parameter
GUEST_TOKEN_JWT_EXP_SECONDSis more than 300 (5 minutes). Otherwise it will expire before it can be refreshed. For example, set it to 600 (10 minutes). -
In the template where you want to integrate the dashboard, add the following in your
<head>:
<link href="{% static 'css/ponctual-rejects.css' %}" rel="stylesheet"/>
- Then add the following at the emplacement where you want the dashboard:
{% load static %}
...
{% include "django_superset_integration/superset-integration.html" %}
-
Run
python manage.py migrateto create the models. -
Start the development server and visit the admin site to create a
SupersetInstanceobject.- address: the address of your Superset instance
- username: the username that allows to connect via api to your instance. By default : superset_api You need to have a service account with minimal permissions to embed dashboards. See Superset documentation for more info.
- password: the password that allows to connect via api to your instance.
-
After you have created a
SupersetInstanceobject, create aSupersetDashboardobject.- integration_id: the integration id given by Superset to integrate your dashboard
- name: a name for your dashboard
- domain: (foreign key) the SupersetInstance object corresponding to the instance where the dashboard is
- comment: (optional) a plain text comment
- superset_link: (optional) the link to your dashboard in Superset
-
In the view where you want to integrate the dashboard, in
get_context_data, add the following:
from django_superset_integration.models import SupersetDashboard
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
...
dashboard_name = "THE NAME OF YOUR DASHBOARD FROM STEP 13"
dashboard = SupersetDashboard.objects.get(name__iexact=dashboard_name)
context["dashboard_integration_id"] = dashboard.integration_id
context["dashboard_id"] = dashboard.id
context["superset_domain"] = dashboard.domain.address
...
return context
- That should be it!
