Hi,   I want to know that how 'params' get created in rails?   when http: request comes we have get all parameter using hash params    e.g:- params[:id]    But in ActionController how params get created and how it is initialised there?    Also what is scope for params?

             Thanks.

It's created from the request body and query string (details of the parsing are in request.rb). It's an instance method on controllers (which views can call via the usual magic).

Could you explain me this in detail ?

Unless there's something specific you're after you're better off
reading the code yourself. It's just a bunch of regexpy type things
pulling apart the query string/form data
