|Rails: Is it safe to use params[:bar] in link_to helper?|
params[:bar] simply returns a value, which could be a String, Fixnum,
Array, etc. It is no different than passing any other link_to params.
No additional caution beyond Rails' conventions is needed since your
example will only be sending a GET request.

records. For example, if in your event#new action, you may have
@event = Event.new
question = @event.questions.build
This will create a new Event and take you to the New page. Within your
New page, you should have nested fields to create and updat
