[GitHub] [airflow] MaksYermak opened a new issue #22360: Jinja templating in Airflow can´t template class Object´s property
MaksYermak opened a new issue #22360:
URL: https://github.com/apache/airflow/issues/22360
### Apache Airflow version
main (development)
### What happened
When you will try to create an Object in operator properties and for this Object you will try to template his property in this case Jinja will not work.
Code example:
```
create_batch = DataprocCreateBatchOperator(
task_id="create_batch",
project_id=PROJECT_ID,
region=REGION,
batch=Batch(
pyspark_batch=PySparkBatch(
main_python_file_uri="main_python_file_uri",
python_file_uris="files",
args=[
"--start-date",
"{{ data_interval_start }}", # it doesn't work
"--end-date",
"{{ ds }}", # it doesn't work
"--table",
"table_name",
"--source-bucket",
"source_bucket",
"--source-prefix",
"source_prefix",
"--output-path",
"path",
],
),
),
batch_id=f"pyspark-table-{str(uuid4())}",
)
```
Result:
### What you think should happen instead
_No response_
### How to reproduce
For reproduce you can run this code
```
import os
from datetime import datetime
from uuid import uuid4
from airflow import models
from google.cloud.dataproc_v1 import Batch, PySparkBatch
from airflow.providers.google.cloud.operators.dataproc import (
DataprocCreateBatchOperator,
)
PROJECT_ID = os.environ.get("GCP_PROJECT_ID", "an-id")
REGION = os.environ.get("GCP_LOCATION", "europe-west1")
with models.DAG(
"example_gcp_batch_dataproc",
schedule_interval='@once',
start_date=datetime(2021, 1, 1),
catchup=False,
) as dag_batch:
create_batch = DataprocCreateBatchOperator(
task_id="create_batch",
project_id=PROJECT_ID,
region=REGION,
batch=Batch(
pyspark_batch=PySparkBatch(
main_python_file_uri="main_python_file_uri",
python_file_uris="files",
args=[
"--start-date",
"{{ data_interval_start }}", # it doesn't work
"--end-date",
"{{ ds }}", # it doesn't work
"--table",
"table_name",
"--source-bucket",
"source_bucket",
"--source-prefix",
"source_prefix",
"--output-path",
"path",
],
),
),
batch_id=f"pyspark-table-{str(uuid4())}",
)
