Save empty translations

[itdxer]

I have 4 translation in my site and 4 tabs for them. When I try create news for example with one translation and I save it it also create 3 another as "" strings.
How I can save just not void translations?

I was looking for the same answer. I made a proof of concept with this before filter:

# Model is Article
before_filter only: [:create, :update] do
  params[:article][:translations_attributes].delete_if do |k,v|
    v.except('id', 'locale').all? { |_,v| v.blank? }
  end
end

While this works I don't like this solution. Another option would be to insert some javascript that does the same thing but client side disabling or removing empty elements from the submitted values.

@stefanoverna what do you think? I can try to work with javascript if it's fine for you.
