Create multiple records using strong params-CodePudding

I'm newbie to Ruby/Rails world and I have the following problem that I'm struggle to make it work.

I have the following sample structure of json data which I'm trying to save in database.

{ "new_contacts"=>
[{"given_name"=>"John", "family_name"=>"Doe", "cell"=>"123456", "country_code"=>"IT"}, 
{"given_name"=>"Sara", "family_name"=>"Peti", "cell"=>"221214", "country_code"=>"IT"}] }

Now inside my controller I have the following code to process this json data and try to save them.

def multi_create
  results =  @contact_book.contacts.create(new_contacts_params)
end
  
def new_contacts_params
  params.require(:new_contacts).permit([ :given_name, :family_name, :cell, :country_code ])
end

I have tried many combinations but with no luck. Can anyone help me please.

Thanks in advance

To permit nested keys in array and require parent key you can use

params
  .permit(new_contacts: %i[given_name family_name cell country_code])
  .require(:new_contacts)
