query string

can anybody tell me how to get the values from querystring.

params[:param_name]

So say for example you're using pagination and you want the page_number param list?page_number=1 :

params[:page_number]

The params are in a hash (eg {"action"=>"list", "filter"=>"closed", "controller"=>"issue"} . If you want to iterate through them for example use:

params.each do |key, value|
  #do something fancy!
end

hi pty,

is there any special function to retrive the complete query string path,i have read from manual that this function is used to retrieve complete string,
ENV,but i am not able to get it working.

env["QUERY_STRING"] should work.

thanx gary for your reply but i want to know that ,do i need to install or include some file to get it working as its not working if i only add this line of code only.

Try using controller.env, where controller is the name of the controller where you are using this.
