python - 立即打印 Celery for Python 中已编程任务的任务 ID

Question

当我从 Django 中的 View 发送一个已编程的任务时，如果我需要在第二时刻撤销，我需要立即获取 task.id。

例如我的观点:

@login_required
def program_task(request, pk):
    member = get_object_or_404(Post_Blog, pk=pk)
    if request.method == "POST":
        form = PostProgrammaForm(request.POST)
        if form.is_valid():
            action = form.save(commit=False)
            action.account_id = member.pk
            action.programmed = 1
            year= action.dataprogrammato.year
            month= action.dataprogrammato.month
            day= action.dataprogrammato.day
            hourz = action.oraprogrammato.hour
            hour= oraz - 2 ##this is for timezone :D
            minute= action.oraprogrammato.minute
            quando = datetime(year, month, day, hour, minute)
            action.save()

            if action.programmed == True:
                tasksend.apply_async(args=(action.id), eta=quando)
                ### here it send task and work, but I need to know here the task.id
            return redirect('blog_action', pk=member.pk)
    else:
        form = PostProgrammaForm(request.POST)
    return render(request, 'FBIsystem/post_program.html', {'form': form, 'member':member})

现在，我的 celery py 是这样的:

app = Celery()
@app.task(bind=True)
def tasksend(self, action_id):
    ###do somethig

一切正常，我保存表格并发送任务，但是...... 如果我为明天编写一篇文章，并且需要在运行之前撤销任务，我该怎么办？

请帮忙 谢谢

apply_async 返回具有 id

的 celery.result.AsyncResult 任务实例

task = tasksend.apply_async(args=(action.id), eta=quando)
print(task.id)
