YAREL

YQL Object Relational Mapper for Ruby

Example

require 'yarel'

Yarel::GeoPlacetypes.all
# Generated YQL: "SELECT * FROM geo.placetype"
# => [{"uri"=>"http://where.yahooapis.com/v1/placetype/0", ..}, ..]

Yarel::GeoPlaces.where(:text => "north beach, san francisco").all
# Generated YQL: "SELECT * FROM geo.places WHERE text = 'north beach, san francisco'"
# => [{"name"=>"North Beach", "woeid"=>"2460640", ... }]


Yarel::GeoPlaces.select("centroid.latitude, centroid.longitude").where(:text => "north beach, san francisco").all
# Generated YQL: "SELECT centroid.latitude, centroid.longitude FROM geo.places WHERE text = 'north beach, san francisco'"
# => [{"centroid"=>{"latitude"=>"37.805939", "longitude"=>"-122.411118"}}]


Yarel::SearchNews.where(:query => "election").limit(10,2).to_yql
# => "SELECT * FROM search.news WHERE query = 'election' LIMIT 2 OFFSET 10"


sub_query = Yarel::GeoPlaces.select("centroid.latitude, centroid.longitude").where(:text => "north beach, san francisco")
Yarel::LocalSearch.where("(latitude,longitude)" => sub_query).where(:radius => 1, :query => 'pizza').sort('AverageRating').to_yql
# => "SELECT * FROM local.search WHERE (latitude,longitude) in ( SELECT centroid.latitude, centroid.longitude FROM geo.places WHERE text = 'north beach, san francisco' ) AND radius = '1' AND query = 'pizza' | sort(field='AverageRating')"
