GET, PUT, POST, and DELETE are few standard methods used in the Django rest framework. To test whether your DAG can be loaded and doesn't contain syntax errors, you run the following command: python your-dag-file.py To test for import errors, run a command similar to the following example: import pytest from airflow.models import DagBag def test_no_import_errors(): dag_bag = DagBag() Django is a full-stack Python web framework that helps in developing a maintainable and secure application in an easy way and in a shorter time.

The decorated function (dag.cellfn) will do whatever it was written to do and eventually call the reference function (XYZ). Decorators are often used to minimize code repetition, say you ...What this means is that before your XYZ function gets called, it will first call the dag.cellfn function with 2 arguments, a reference to XYZ and dag.CanSet.
