check db calls django

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