Description

GCal4Ruby has three major components: the service, calendar and event objects. Each service has many calendars, which in turn have many events. Each service is the representation of a google account, and thus must be successfully authenticated using valid Google Calendar account credentials.

Examples

Below are some common usage examples. For more examples, check the documentation.

Service

Authenticate

service = Service.new
service.authenticate("[email protected]", "password")

Get Calendar List for all calendars
```
calendars = service.calendars
```
Get Calendar List for all calendars that the authenticated user has owner access level
```
calendars = service.calendars(:only_owner_access_level => true)
```

Calendar

All usages assume a successfully authenticated Service.

Create a new Calendar
```
cal = Calendar.new(service)
```

Find a calendar by ID

cal = Calendar.find(service, {:id => cal_id})

Get all calendar events

cal = Calendar.find(service, {:id => cal_id})
events = cal.events

Find an existing calendar by title

cal = Calendar.find(service, {:title => "New Calendar"})

Find all calendars containing a search term

cal = Calendar.find(service, "Soccer Team")

Event

All usages assume a successfully authenticated Service and valid Calendar.

Create a new Event

event = Event.new(service, {:calendar => cal, :title => "Soccer Game", :start => Time.parse("12-06-2009 at 12:30 PM"), :end > Time.parse("12-06-2009 at 1:30 PM"), :where => "Merry Playfields"})
event.save

Find an existing Event by title

event = Event.find(service, {:title => "Soccer Game"})

Find an existing Event by ID

event = Event.find(service, {:id => event.id})

Find all events containing the search term

event = Event.find(service, "Soccer Game")

Find all events on a calendar containing the search term

event = Event.find(service, "Soccer Game", {:calendar => cal.id})

Find events within a date range

event = Event.find(service, "Soccer Game", {'start-min' => Time.parse("01/01/2010").utc.xmlschema, 'start-max' => Time.parse("06/01/2010").utc.xmlschema})

Create a recurring event for every saturday

event = Event.new(service)
event.title = "Baseball Game"
event.calendar = cal
event.where = "Municipal Stadium"
event.recurrence = Recurrence.new
event.recurrence.start_time = Time.parse("06/20/2009 at 4:30 PM")
event.recurrence.end_time = Time.parse("06/20/2009 at 6:30 PM")
event.recurrence.frequency = {"weekly" => ["SA"]}
event.save

Create an event with a 15 minute email reminder

event = Event.new(service)
event.calendar = cal
event.title = "Dinner with Kate"
event.start_time = Time.parse("06/20/2009 at 5 pm")
event.end_time = Time.parse("06/20/2009 at 8 pm")
event.where = "Luigi's"
event.reminder = {:minutes => 15, :method => 'email'}
event.save

Create an event with attendees

event = Event.new(service)
event.calendar = cal
event.title = "Dinner with Kate"
event.start_time = Time.parse("06/20/2009 at 5 pm")
event.end_time = Time.parse("06/20/2009 at 8 pm")
event.attendees => {:name => "Kate", :email => "[email protected]"}
event.save
