Create a .env file in the root directory of your Django project.

Add your Supabase API URL and API key to the .env file:
```
SUPABASE_URL=
SUPABASE_KEY=
```

Load the .env file in your settings.py:
```python
import environ

env = environ.Env()
environ.Env.read_env()

SUPABASE_URL = env('SUPABASE_URL')
SUPABASE_KEY = env('SUPABASE_KEY')
```

Create a utility file to handle Supabase interactions, let's call it supabase_utils.py:
```python
import requests
from django.conf import settings

SUPABASE_URL = settings.SUPABASE_URL
SUPABASE_KEY = settings.SUPABASE_KEY

headers = {
"apikey": SUPABASE_KEY,
"Content-Type": "application/json",
"Authorization": f"Bearer {SUPABASE_KEY}"
}

def fetch_from_supabase(endpoint):
url = f"{SUPABASE_URL}/rest/v1/{endpoint}"
response = requests.get(url, headers=headers)
return response.json()
def insert_to_supabase(endpoint, data):
url = f"{SUPABASE_URL}/rest/v1/{endpoint}"
response = requests.post(url, json=data, headers=headers)
return response.json()
```

Import supabase_utils.py into your Django views and use its functions to interact with Supabase:
```python
from django.http import JsonResponse
from .supabase_utils import fetch_from_supabase, insert_to_supabase

def fetch_data_view(request):
data = fetch_from_supabase('your_table_name')
return JsonResponse(data, safe=False)
def insert_data_view(request):
if request.method == 'POST':
data = request.POST.dict()
response = insert_to_supabase('your_table_name', data)
return JsonResponse(response, safe=False)
```

Map the new views to URLs in your urls.py:
```python
from django.urls import path
from . import views

urlpatterns = [
path('fetch-data/', views.fetch_data_view, name='fetch_data'),
path('insert-data/', views.insert_data_view, name='insert_data'),
]
```
