Google Cal API Python：多次删除且 ExecuteBatch 失败

Question

我尝试使用 Google API for python 删除日历的所有事件。 如果我一一删除事件，这可以正常工作，但它很长并且没有优化，因此我尝试使用 ExecuteBatch 执行相同的操作，我用它在日历中插入大量条目（并且在插入之前工作正常）。

def DeleteAllEntryOfCalendar(calendar_client, name_calendar):
    #Request_feed for doing the delete
    request_feed = gdata.calendar.CalendarEventFeed()
    #Get the Uri of the cal we've to delete all entries
    uri = GetUri(calendar_client, name_calendar)
    feed = calendar_client.GetAllCalendarsFeed()
    for a_cal in feed.entry:
        if a_cal.title.text == name_calendar:
            calendar = a_cal    
    #For each entry in the cal, do a delete request entry in request_feed
    query = gdata.calendar.client.CalendarEventQuery()
    query.max_results = 1000
    feed = calendar_client.GetCalendarEventFeed(uri=uri, q=query)
    for an_entry in feed.entry:
        an_entry.batch_id = gdata.BatchId(text='delete-request')
        request_feed.AddDelete(entry=an_entry)    
        entry = ''

    # submit the batch request to the server
    response_feed = calendar_client.ExecuteBatch(request_feed, uri+u'/batch')

我收到错误：

Traceback (most recent call last):
  File "c.py", line 253, in <module>
    DeleteAllEntryOfCalendar(client, name_calendar)
  File "c.py", line 187, in DeleteAllEntryOfCalendar
    response_feed = calendar_client.ExecuteBatch(request_feed, uri+u'/batch')
  File "/usr/local/lib/python2.6/dist-packages/gdata/calendar/client.py", line 432, in     execute_batch
    return self.Post(batch_feed, url, desired_class=desired_class)
  File "/usr/local/lib/python2.6/dist-packages/gdata/client.py", line 681, in post
    entry.to_string(get_xml_version(self.api_version)),
AttributeError: 'CalendarEventFeed' object has no attribute 'to_string'

我重复一遍，当我执行相同操作来插入事件时，效果很好。 我进行了很多搜索并尝试了很多可能性，但我无法做到这一点。 如果你有一个想法...

使用

gdata.calendar.data.CalendarEventFeed

gdata python 库中的某些对象有两个版本，您不能将它们混合在一起。
