Question

I am playing around with dynamic links for objects and came up with this:

link = link_to 'New', send("new_#{params[:controller].singularize}_path")

I am specially interested in the send part. Is this a good practise and are there alternatives?

Answer 1

It’s better than other to use send. eval is less good.

But in the link_to case you can use an url_for format

link = link_to 'New', {:controller => params[:controller], :action => 'new'}
