##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

1. Authenticate

    service = Service.new
    service.authenticate("user@gmail.com", "password")
   

2. Get Calendar List

    calendars = service.calendars
   

###Calendar

All usages assume a successfully authenticated Service.

1. Create a new Calendar

    cal = Calendar.new(service)
   

2. Find a calendar by ID

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

3. Get all calendar events

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

4. Find an existing calendar by title

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

5. Find all calendars containing a search term

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

###Event

All usages assume a successfully authenticated Service and valid Calendar.

1. 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
   

2. Find an existing Event by title

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

3. Find an existing Event by ID

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

4. Find all events containing the search term

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

5. Find all events on a calendar containing the search term

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

6. 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})
   

7. 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 
   

8. 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
   

9. 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 => "kate@gmail.com"}
    event.save
