check db calls django
- Use Django's ORM to define a model for the database table you want to query.
- Use the queryset API to create a query that retrieves the data you need from the database.
- Use filter(), exclude(), get(), or other query methods to narrow down the results based on specific conditions.
- Use the values() or values_list() methods to specify which fields to retrieve from the database.
- Use the annotate() and aggregate() methods to perform aggregation and annotation on the query results.
- Use the order_by() method to specify the ordering of the results.
- Use the distinct() method to eliminate duplicate rows from the query results, if needed.
- Use the query's iterator() method for iteration over large querysets to avoid loading all objects into memory at once.
