airflow.providers.standard.operators.weekday¶

類¶

BranchDayOfWeekOperator

根據當前日期將流程分發到兩個任務列表之一。

模組內容¶

class airflow.providers.standard.operators.weekday.BranchDayOfWeekOperator(*, follow_task_ids_if_true, follow_task_ids_if_false, week_day, use_task_logical_date=False, **kwargs)[原始碼]¶

繼承自：airflow.providers.standard.operators.branch.BaseBranchOperator

根據當前日期將流程分發到兩個任務列表之一。

關於如何使用此運算元的更多資訊，請參閱指南：BranchDayOfWeekOperator

示例（包含單個日期）

from airflow.providers.standard.operators.empty import EmptyOperator
from airflow.operators.weekday import BranchDayOfWeekOperator

monday = EmptyOperator(task_id="monday")
other_day = EmptyOperator(task_id="other_day")

monday_check = BranchDayOfWeekOperator(
    task_id="monday_check",
    week_day="Monday",
    use_task_logical_date=True,
    follow_task_ids_if_true="monday",
    follow_task_ids_if_false="other_day",
)
monday_check >> [monday, other_day]

示例（使用 WeekDay 列舉）

# import WeekDay Enum
from airflow.providers.standard.utils.weekday import WeekDay
from airflow.providers.standard.operators.empty import EmptyOperator
from airflow.operators.weekday import BranchDayOfWeekOperator

workday = EmptyOperator(task_id="workday")
weekend = EmptyOperator(task_id="weekend")
weekend_check = BranchDayOfWeekOperator(
    task_id="weekend_check",
    week_day={WeekDay.SATURDAY, WeekDay.SUNDAY},
    use_task_logical_date=True,
    follow_task_ids_if_true="weekend",
    follow_task_ids_if_false="workday",
)
# add downstream dependencies as you would do with any branch operator
weekend_check >> [workday, weekend]

引數：

follow_task_ids_if_true (str | collections.abc.Iterable[str]) – 如果滿足條件，要執行的 task_id、task_group_id 或 task_id 和/或 task_group_id 的列表。
follow_task_ids_if_false (str | collections.abc.Iterable[str]) – 如果不滿足條件，要執行的 task_id、task_group_id 或 task_id 和/或 task_group_id 的列表。
week_day (str | collections.abc.Iterable[str] | airflow.providers.standard.utils.weekday.WeekDay | collections.abc.Iterable[airflow.providers.standard.utils.weekday.WeekDay]) –
要檢查的星期幾（全名）。也可以選擇使用集合提供一組日期。示例值：
- "MONDAY",
- {"Saturday", "Sunday"}
- {WeekDay.TUESDAY}
- {WeekDay.SATURDAY, WeekDay.SUNDAY}
要使用 WeekDay 列舉，請從 airflow.utils.weekday 匯入它
use_task_logical_date (bool) – 如果為 True，則使用任務的邏輯日期與 is_today 進行比較。執行日期對於回填很有用。如果為 False，則使用系統的星期幾。

follow_task_ids_if_true[原始碼]¶

follow_task_ids_if_false[原始碼]¶

week_day[原始碼]¶

use_task_logical_date = False[原始碼]¶

choose_branch(context)[原始碼]¶

選擇執行哪個分支的抽象方法。

子類應實現此方法，執行選擇分支所需的任何邏輯，並返回一個或多個 task_id。

引數：: context (airflow.sdk.definitions.context.Context) – 傳遞給 execute() 的上下文字典
