My models

• Value
• Wordmeaning

I only need the ability to add meanings that are already available for the word?

      class Word < ActiveRecord::Base    
         belongs_to :language    
         has_many :word_meanings
         has_many :meanings ,through: :word_meanings

form do |f|

f.semantic_errors *f.object.errors.keys
f.inputs do
  f.input :language
  f.input :word
  f.input :wordInScript
  f.input :pronunciation, :required => false, :as => :file
end

f.inputs do
  f.has_many :meanings, heading: 'Meanings', allow_destroy: true, new_record: true do |a|
    a.input :meaning
    a.input :language
  end
end

f.actions
end
