#_localVariable(args) ⇒ Object

Questo metodo permette di avere le variabili locali di locals disponibili nel file erb file .rb

  • es. render(template: “test/index”, layout: ‘application’, locals: ‘herbert’, surname: ‘bonaffini’)

file .html.erb

  • es. <%= “Name: #name, Surname: #href=":surname">locals” %

by this method you can set another layout as on rails. It is enough to call layout in your controller example1: layout(“layout_name”) # static example2: layout :determine_layout # dynamic where determine_layout is a method name
