in [Ruby]

From: 12 34 on 2 Jun 2010 01:57 A Ruby newbie having trouble getting results back from geonames #!/usr/bin/env ruby require "rubygems" require 'geonames' places_nearby = Geonames::WebService.find_nearby_place_name 41.505928,-81.594582 p places_nearby # --> [#<Geonames::Toponym:0x1021042f0 @country_code="US", @feature_code_name=nil, @elevation=nil, @distance=0.4495, @alternate_names=nil, @feature_code="PPLX", @population=nil, @geoname_id="5161005", @longitude=-81.5981817, @feature_class_name=nil, @country_name="United States", @name="Little Italy", @latitude=41.5089406, @feature_class="P">] How do I get any of the values, e.g., country_name? places_nearby is a local variable. Thank you in advance for help. I've tried several things, but can't figure it out. -- Posted via http://www.ruby-forum.com/.
From: Sven Schott on 2 Jun 2010 02:11 [Note: parts of this message were removed to make it a legal post.] Have you tried just calling the name of the instance var? Sometimes nice developer set up easy setters and getters in their implementations. e.g. places_nearby[0].country_code Just a thought. What are you trying that's failing? Have you looked through the docs at http://www.tbcn.ca/ruby_geonames On Wed, Jun 2, 2010 at 3:57 PM, 12 34 <rubyforum(a)web.knobby.ws> wrote: > A Ruby newbie having trouble getting results back from geonames > > #!/usr/bin/env ruby > require "rubygems" > require 'geonames' > > places_nearby = Geonames::WebService.find_nearby_place_name > 41.505928,-81.594582 > p places_nearby # --> [#<Geonames::Toponym:0x1021042f0 > @country_code="US", @feature_code_name=nil, @elevation=nil, > @distance=0.4495, @alternate_names=nil, @feature_code="PPLX", > @population=nil, @geoname_id="5161005", @longitude=-81.5981817, > @feature_class_name=nil, @country_name="United States", @name="Little > Italy", @latitude=41.5089406, @feature_class="P">] > > How do I get any of the values, e.g., country_name? places_nearby is a > local variable. > > Thank you in advance for help.

I had tried places.country_name among others. Why the "first"? places_nearby[0].country_code works too. The docs didn't suggest how to parse the result. Thank you for the answers, but I'm not sure why it's working. But I can proceed. -- Posted via http://www.ruby-forum.com/.
