You can also do something like Search.find(:all, :select => "word", :limit=>3, :order =>"count desc") if you only need the word column from each record and want to be a little easier on memory.
Also, be careful with the Symbol#to_proc shorthand ( map(&:word) ) with large arrays, as it is pretty CPU-inefficient in Rails from what I understand. http://blog.hasmanythrough.com/2006/3/7/symbol-to-proc-shorthand (check the comments) Jarin Udom Robot Mode LLC On Feb 15, 10:21 pm, Samiron <samironp...@gmail.com> wrote: > Assuming the followings: > - Your Search model have a column "word" > - @top_search is a array with 3 latest search result, where each > element have a :word > - You want to join words from these 3 search objects > > Then you just can do as following: > �...@top_search.map(&:word).join(',') > > Hope it will work if my assumptions are correct :) > > On Feb 16, 12:01 pm, Greg Ma <li...@ruby-forum.com> wrote: > > > > > Hello, > > Is it possible to make a "join" on an array of objects? > > If not, is is possible to return only one column with the find method? > > > #method > > def self.top_3_words > > Search.find(:all,:limit=>3, :order =>"count desc") > > end > > > #View > > <% if !...@top_search.blank? %> > > <%= @top_search.word.join(",") %> ????????????????? > > <% else %> > > <p>No search yet!</p> > > <% end %> > > > Greg > > -- > > Posted viahttp://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
