Validates inclusion failing for I18n in Rails 4.0

I have the following model. 

class Ingredient < ActiveRecord::Base
  UNITS = [
            { name: "Unit" },
            { name: "Teaspoon" }
  ]
  validates :unit, inclusion: UNITS.map{|u| I18n.t(u[:name]) }
end

In the console. running the following command when the locale if :fr (french), yields the following based out of my locale file. 

#Ingredient::UNITS.map{ |u| I18n.t(u[:name]) }
["Unité","Cuillère à café",]

Which is correct, however the validation fails for this, when I do the following. 

Ingredient.create(quantity: 4.0, unit: "Cuillère à café")

When I manually check if the unit is included within the array, I get true. Why is this validation failing? Works correctly for english.

Validators are defined when the class is loaded for the first time and do not change later on. In your example that means that

validates :unit, inclusion: UNITS.map{|u| I18n.t(u[:name]) }

is evaluated to 

validates :unit, inclusion: ['Unit', 'Teaspoon']

and will not change to another locale in a later request.

It might work to assign a lambda instead on an array, like this:

validates :unit, inclusion: { in: proc { UNITS.map { |u| I18n.t(u[:name]) } } }
