I am having an issue where the global variable, $r, which i declared in the controller is being overwritten by my code which is in a view: <%= link_to ''Picks test1'', game_pick_page_path, :onclick => $r = 1 %> <%= link_to ''Picks test2'', game_pick_page_path, :onclick => $r = 2 %> The first $r = 1 is overwritten by $r = 2 making the value 2 even if i click picks test1. i want it to just set $r to which every value is associated with the link the user clicks. Any ideas on how to make this happen would be greatly appreciated. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

If you don''t want the global to be changed, why are you assigning to it? Legitimate uses are few and far between, I''m sure an alternative can be suggested if you can clarify your intent.

When the user clicks the ''picks1'' link I want $r to be equal to 1. when the user clicks ''picks2'' i wont $r to be equal to 2. At this moment with the code i have presented earlier i constantly get $r equal to 2 whether i click the second link or not. What is happening is that the code is being read over and actually changing $r instead of just doing so when the user clicks the links with the onclick. I need to figure a way to change the $r so that it will change based on the link the user clicks... i already had it set up with a model and it worked but i soon realized that the amount of data entries was not ideal. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

If you want to remember the value without storing it in the database, use the session (set session[:foo]) rather than a global - a global would share its value across all users of the site and won''t work consistently if you have more than 1 passenger/unicorns instance Fred> > -- > Posted viahttp://www.ruby-forum.com/.-- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

How do i define it in the controller and view? -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
