Hello, I''m just trying to figure out how to put a variable into a link_to. I want to have the number of rows from my SQL statement in it. For example: perfect matches (123) where 123 is the number of rows. I currently have the number of rows in an array, but it just displays rows[pm_rows] (when I put rows[''pm_rows''] it kicks a compile error due to the quotes) because its in quotations.... how can I escape this? My link_to looks like this: <%= link_to ''perfect matches (rows[pm_rows])'', :controller => ''compare'', :action => ''perfectmatches'' %> Any help is appreciated! Thank you! - Jeff Miller -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Instead, you set some arbitrary hash key to the value in question in the URL part of the link_to, and then inside the link''ed to action you access it through the "params" with the key you gave it: <%= link_to ''perfect matches'', :url => {:controller => ''compare'', :action => ''perfectmatches'', :my_rows => rows[pm_rows]} %> def perfectmatches my_rows = params[:my_rows] ... end HTH, jp -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Hello, Thanks for your response! The thing is, I''m trying to get this variable into the link text, not trying to send it somewhere. My controller comes up with the number of rows and I want to put it in the link text so it would read something like "perfect matches (200)" where 200 would be rows[''pm_rows'']... The quotes just kill it each time though.... Any suggestions? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I got it to work, thanks!
<% for rows in @pm_rows %>
<%= link_to "perfect matches
(#{rows[''pmrows'']})", :controller =>
''compare'', :action => ''index'' %>
<% end %>
