ruby on rails - How globalize gem decides which content goes to translated table? -

in rails 4.2 app have set default locale setting in config/application.rb:

config.i18n.default_locale = :it 

i have simple "product" model

class product < activerecord::base     translates :name, :description end 

my need when i18n.locale = :it content should written in "products" table while others locales content shoud go in "product_translations" table. happens following:

if

config.i18n.default_locale = :en 

content written "products" table, different locales content goes "product_translations" table.

how can change this?

edit

using console test globalize behaviour found maybe did not understand how globalize should work. expecting "products" table filled default_locale (in case :it) , "product_translations" table filled other locales (:en, :fr, :de , on).

instead see whichever locale is, fields indicated

translates :name, :description 

are always written in "product_translations" , "product" table contains fields not translated (in case uom (unit of measure). output of console after saving new product :en locale.

is default behaviour? need remove translatable fields original table?
