I have a PhotoSet, which has a one_to_many relationship with Photos. Each
Photo has a latitude (lat) and longitude (lng) associated with it, along
with (DateTime) date_taken.
Using Sinatra as a REST service, my desired output would be:
[{
title: set1,
photos: [[lat1, lng1],[lat2, lng2]] # or even better, photos renamed to
'route'
}]
...with each [lat, lng] ordered by date_taken...
Totally lost as to how to achieve this, I can get this far using Sequel's
JSON Serializer plugin:
PhotoSet.where(:parent_id => nil)
.to_json(:include => {
:photos => {
:only => [:lat, :lng],
},
})
which returns:
[
{
"id": 1,
"title": "",
"date_created": "2013-09-14T15:53:16+00:00",
"photos": [
{
"lat": 52.95386867000556,
"lng": -2.2866811700101857
}
]
}
]
Thanks,
Adam
