Array of hashes with string values

[dmitry]

I have a form with translations, which I'm generating with following code:

= f.simple_fields_for 'translations[]', translation do |ft|
  = ft.input :locale, as: :hidden
  = ft.input :name

In the result I'm receiving following parameters:

{"item"=>{"translations"=>[{"locale"=>"en", "name"=>""}, {"locale"=>"es", "name"=>""}]}}

Is it possible to filter such attributes with active_interaction?

I know it's possible with:

hash :translations, strip: false

But it's not strict enough, so I have to use strong_parameters, which I would like to reject at all in project.

Looks like logically this code should work:

    array :translations do
      string :name
      string :locale
    end

But it's not, as it's returns: attribute names in array block.

Should I make a PR with support of hash block in array, or it's possible to solve that somehow in other way around?

Does this work?

array :translations do
  hash do
    string :locale
    string :name
  end
end

array inputs can only have one input nested underneath them. This is because every element of the array must be the same type. And the inputs nested inside arrays cannot have names because they would never be used.

@tfausak thanks for the quick reply 👍.

I've tried that in the beginning, but looks like forgot something in integration with accepts_nested_attributes_for. Now it perfectly works. Thanks again!

No problem. Happy to help!
