> Key: AIRFLOW-2493
> URL: https://issues.apache.org/jira/browse/AIRFLOW-2493
> Project: Apache Airflow
> Issue Type: Improvement
> Affects Versions: 2.0.0, 1.10
> Reporter: roc chan
> Assignee: roc chan
> Priority: Minor
>
> I saw some words from Concepts-Additional Functionality-Jinjia Templating in the document : [http://airflow.readthedocs.io/en/latest/concepts.html?highlight=xcom#jinja-templating]
> *You can use Jinja templating with every parameter that is marked as “templated” in the documentation. Template substitution occurs just before the pre_execute function of your operator is called.*
> But the actual situation of the API document is not like this，only a small portion of template_fields have marked "(templated)", for example, *BashOperator*'s *env* has been marked, but *bash_command* is not ([http://airflow.readthedocs.io/en/latest/code.html#airflow.operators.bash_operator.BashOperator)|http://airflow.readthedocs.io/en/latest/code.html#airflow.operators.bash_operator.BashOperator)*,*], which has caused some confusion. I want every template_fields of all Operators in the API document has marked "(templated)"
