I'm working on a RoR project and I am passing a JSON object to a script. Specifically, a list of events to a jquery calendar.
First I get the necessary events from active record and convert them to json:
@events = CalendarEvent.find(:all, :conditions => ["mentor_id = ?", current_user]).to_json(:only => [:id, :availability, :starts_at, :ends_at])
This returns the following:
[{"calendar_event":{"starts_at":"2010-08-14T17:15:00Z","id":1,"availability":true,"ends_at":"2010-08-14T17:45:00Z"}},
{"calendar_event":{"starts_at":"2010-08-15T15:45:00Z","id":2,"availability":true,"ends_at":"2010-08-15T16:15:00Z"}},
...]
However, I am running into problems because the script is expecting the following format:
[{"starts_at":"2010-08-14T17:15:00Z","id":1,"availability":true,"ends_at":"2010-08-14T17:45:00Z"},
{"starts_at":"2010-08-15T15:45:00Z","id":2,"availability":true,"ends_at":"2010-08-15T16:15:00Z"},
...]
At first I thought it would be a simple matter of popping the values from the separate hashes, and returning an array filled with those. However, it seems that everything in the array is one big string. So I was trying to get the necessary stuff using a regular expression. My best shot was:
@json = @events.scan(/\[\{\"calendar_event\":(\{.*\})\}\]*/)
But this returns something of the form:
[["{\"starts_at\":\"2010-08-14T17:15:00Z\",\"id\":1,\"availability\":true,\"ends_at\":\"2010-08-14T17:45:00Z\"}},{\"calendar_event\":{\"starts_at\":\"2010-08-15T15:45:00Z\",\"id\":2,\"availability\":true,\"ends_at\":\"2010-08-15T16:15:00Z\"}},..."]]
Any help would be appreciated.
