Look at your server''s log, you can find the parameters for each
request.
eg.

For example: This works in old rails versions, but not in (2.2.2), why? @word = params[:search][:word] || params[:word] || "home" The are 2 parameters, one POST and another GET (POST overwrite GET), if there not POST and GET, defaul value is: "home" How can I do it in Rials 2.2.2? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

> @word = params[:search][:word] || params[:word] || "home"you can still do that. there is only a problem if params[:search] is nil. because then you''d try to evaluate nil.[] which again leads to an error. this is what Phlip wanted to tell you way up in this thread. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

MaD is right, no matter what the expression, you will always get an exception if you try to evaluate nil.[] You can divide the expression in two: city = (params[:user]) ? params[:user][:city] || "xxx" : "xxx" Cheers, Sazima On Jan 11, 10:07 am, MaD <mayer.domi...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> > @word = params[:search][:word] || params[:word] || "home" > > you can still do that. there is only a problem if params[:search] is > nil. because then you''d try to evaluate nil.[] which again leads to an > error. this is what Phlip wanted to tell you way up in this thread.--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
