如何将哈希值加倍传递

Question

在某些情况下，我有多个具有相同值的键，因此为了避免重复，我做了如下操作

sports = [:cricket,:football,:basketball,:baseball,:rugby,:swimming,:table_tennis,:soccer,:karate]

final_hash = Hash.new

sports.each{|d| final_hash[d] = OpenStruct.new(categories: [], count: [], user_hash: {}, sport_count: [],  options: {}, period: "",stat_type: "" )  }

现在，我想在我的double块中传递此哈希，但是每当我这样做时，我都会收到错误消息

context 'For users details Page' do
  it 'should give the data' do
    ###now I want to pass the hash SO can anyone guide me how can I do it
    presenter =  double(UserPresenter, id: 1, sector_name: nil, final_hash)
  end
end

正如@engineersmnky所建议的那样，在哈希上使用双splat运算符（** hash）对我有用。
