如何同步Google日历& amp;带有脚本的电子表格 [英] How to synchronize Google Calendar & Spreadsheet with Script
问题描述
我正在尝试创建一个Google Apps脚本，以使Google日历和云端硬盘上的主电子表格"保持同步-这可能吗?我发现了这两篇文章:
I am trying to create a Google Apps Script that keeps a Google Calendar and a "master spreadsheet" on Drive synchronized -- is this possible? I found these two posts:
http://blog.ouseful.info/2010/03/05/grabbing-google-calendar-event-details-into-a-spreadsheet/
我很确定这可以使用很多if语句和逻辑来完成，但是也许有一种更简单的方法吗?
I'm quite sure this could be done using a lot of if statements and logic, but maybe there's a simpler way?
我最终只提供了以下简单脚本.真正必要的是基于两列添加事件，这将花费很长时间来开发.
I ended up just providing the following simple script. All that was really necessary was adding events based on two columns, and this would've taken too long to develop.
function onOpen() {
//spawns a menu with a button that triggers AddToCal
var sheet = SpreadsheetApp.getActiveSpreadsheet();
var entries = [{
name : "Add event to calendar",
functionName : "AddToCal"
}];
sheet.addMenu("Data To Calendar Plugin", entries);
};
function AddToCal(){
//get the current row
var ss = SpreadsheetApp.getActiveSpreadsheet();
var cell = ss.getActiveCell();
var R = cell.getRow();
//grab values for current row to pass to calendar event
var date_of_event = ss.getRange('G'+R).getValue();
var date = new Date(date_of_event);
var event_title = ss.getRange('A'+R).getValue();
//access the calendar
var cal = CalendarApp.getCalendarById('[IDREMOVED]');
cal.createAllDayEvent(event_title,date);
ss.toast("Event added to " + cal.getName());
}
推荐答案
是的，编写双向事件同步脚本是可能，但这并不简单.您引用的这两篇文章的部分可以重用，但是与实际同步将面临的挑战相比，它们是相当基础的.您可能需要阅读将Google Apps脚本用于事件预订系统，该系统的确会基于电子表格创建日历条目(但不会进行持续的同步).过去，我已经对该脚本进行了该脚本的调试.
Yes, it's possible to write a two-way event synchronization script, but it isn't going to be simple. Those two posts you refer have parts that could be reused, but they are quite elementary compared to the challenges you'll face with actual synchronization. You may want to read over Using Google Apps Script for a event booking system which does create calendar entries based on a spreadsheet (but doesn't do on-going synchronization). I've done some debugging of that script in past.
同步需要支持:
- 在任一位置创建事件
- 在任一位置修改事件详细信息(尽管为简化起见，您可以选择仅考虑事件详细信息的子集)
- 删除任一地点的事件
- 重复发生，例如
CalendarEvent.getEventSeries()处理(或选择避免)
- Creation of events in either location
- Modification of event details in either location (although you could opt to consider only a subset of event details for simplification)
- Deletion of events in either location
- Recurrence, e.g.
CalendarEvent.getEventSeries()handling (or choose to avoid)
这是您可以从以下代码开始的伪代码:
This is pseudo-code that you could start with:
Open Calendar, Read Calendar events into calArray (will all attributes you care for)
Open Spreadsheet, Read Spreadsheet events into sheetArray
For each event in calArray:
Search for calEvent in sheetArray.
If found, compare lastUpdated values.
If equal, do nothing
Otherwise copy most recently updated to least recently updated
Continue with next event
If not found then copy calEvent to new sheetEvent, including lastUpdated value.
Continue with next event
For each event in the sheetArray (...that hasn't been handled yet)
Similar logic above.
Write updated sheetArray to spreadsheet.
Write updated calEvents to calendar API (see note 1 below)
注意:
-
所有对calEvents的更新都可以进行数组化，并立即写入日历API，作为批量更新的替代方法.尽管触摸lastUpdated值是一个好主意，但这将消除了在本地跟踪更改的需要.
All updates to calEvents could be made to array and written to calendar API immediately, as an alternative to a bulk update. This would eliminate the need to track the changes locally, although it would be a good idea to touch the lastUpdated value.
在读取calEvent时，您将要使用 CalendarEvent.getLastUpdated()，并在电子表格中存储类似的值(与 onEdit 触发器绑定)以方便比较.
You will want to use CalendarEvent.getLastUpdated() when reading calEvents, and store a similar value in your spreadsheet (tied to an onEdit trigger) to facilitate comparisons.
这将简化比较，以针对电子表格中的事件记录 CalendarEvent.getId().您还具有 CalendarEvent.setTag(key，value)，可用于将自定义元数据记录到日历中，例如，指示源自电子表格或已与电子表格同步的事件.(这些标记无法通过GCal UI进行访问，因此只能通过脚本进行访问.)
It would simplify comparisons to record CalendarEvent.getId() against events in the spreadsheet. You also have CalendarEvent.setTag(key,value) that could be used to record custom metadata into the calendar, for instance to indicate events that originated or have been synchronized with your spreadsheet. (These tags are not accessible through the GCal UI, so would only be accessible via script.)
您应考虑要处理的日期范围或事件数，并限制脚本的范围.否则，您一定会在实际操作中遇到执行时间限制.
You should think about the range of dates or number of events you want to deal with, and limit the scope of the script. If you don't, you are sure to run into execution time limits in real operation.
某些日历事件特征无法在电子表格中轻松表达，例如:
Some Calendar Event characteristics don't lend themselves to easy expression in a spreadsheet, for instance:
- 来宾清单
- 提醒列表
