How to call a PostgreSQL function from Django

To call a PostgreSQL function from Django, you can use Django's database connection along with the raw method or the connection.cursor() method. Here's a basic example using connection.cursor():

from django.db import connection  

def call_postgresql_function():  
    with connection.cursor() as cursor:  
        cursor.callproc('function_name', [param1, param2])  # Replace with your function and parameters  
        result = cursor.fetchall()  # Fetch results if your function returns any  
    return result

Make sure your PostgreSQL function is created and accessible in the database that your Django application is connected to. Double-check that you have the correct permissions and function parameters.
