Question

I have a User model. I also have a form_for(@user…) form. This form spans 3 partials. In order for every partial to remember values I use the following command inside my create action in my UsersController:

session[:user_params].deep_merge!(params[:user]) if params[:user]

This way every partial adds params[:user] to session[:user_params]. I also have other form values stored inside the params hash which are not part of the User model. Is there a command which would allow me to add all single params values (not just the :user hash) to the session[:user_params] hash without adding every single value one by one like this:

session[:num_children] = params[:num_children] if params[:num_children]
...etc...

Try:

params.each {|key,value| session.deep_merge!(key=>value)}
