= semantic\_form\_for @company do |f|  
= f.semantic\_fields\_for :categorizations do |categorization|  
= categorization.input :classification

Uso formtastic ma non cambia nulla rispetto agli helper nativi di rails.

Tramite l’associazione categorizations posso fare:  
@company.categorizations.each { |x| x.category.name }  
Siccome fields\_for itera su tutti gli elementi dell’associazione  
vorrei ottenere qualcosa del genere

= f.semantic\_fields\_for :categorizations do |categorization|  
= categorization.label :category.name  
= categorization.input :classification

Cioe’ vorrei visualizzare il nome della categoria per ogni  
categorization.  
C’e’ un modo per poterlo fare?

Risolto:

- @company.categorizations.each do |categorization|  
= f.semantic\_fields\_for :categorizations, categorization do |cat|  
= categorization.category.name  
= cat.input :classification
