ruby on rails - How do I create a link (or button) that will execute an Application Helper method? -


i new ruby/rails , trying create links update variable in session. have following method defined in application_helper.rb--i put here in hopes correct place have can used all views:

module applicationhelper def add_workspace_to_session(workspace_id) session[:workspace_id] = workspace_id end end

in view want create simple link (or button) call helper, passing in workspace id updates session[:workspace_id]. how make link in view? using link_to? i'm missing something...having routes?

thanks!

if creating button or link should pointed url path not helper method. quick fix add path helper method.

note: have not tested passing parameter. 

 def add_workspace_to_session(workspace_id, url) session[:workspace_id] = workspace_id url end <%= button_to "store workspace", add_workspace_to_session(workspace_id, root_path), :method => :get %>

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
