Can't import Airflow plugins

Following Airflow tutorial here.

Broken DAG: [/usr/local/airflow/dags/test_operat         


        

Answer 1

In my case I managed to make a custom operator with the following steps:

1. Airflow 10.3
2. in DAG File from airflow.operators import MacrosPostgresOperator
3. In ~/airflow/plugins folder I have a python file custom_operator.py and the code is pretty simple

from airflow.plugins_manager import AirflowPlugin
from airflow.operators.postgres_operator import PostgresOperator

 class MacrosPostgresOperator(PostgresOperator):
    template_fields = ('sql', 'parameters')

class MacrosFirstPlugin(AirflowPlugin):
    name = "macros_first_plugin"
    operators = [MacrosPostgresOperator]
