在jinja模板中,使用{% raw %}{% %}{% endraw %}标签将JavaScript代码包裹起来,以告诉jinja这是原始的未处理的代码。 在循环开始之前,使用{% raw %}{% set %}{% endraw %}标签定义一个jinja变量,并将其设置为JavaScript变量的值。 在循环中,使用jinja变量来引用JavaScript变量。 下面是一个示例,演示如何...
But it's not possible, we thus need to hard-code {{ ti.xcom_pull(task_ids='my_previous_task') }} inside my_sql_script.sql script. But later in the code, we don't want s3_file_name to come from xcom but rather from a python variable, and it's impossible because it's hard...
