如何以双精度传递哈希

Question

有一种情况，我有多个具有相同值的键，为了避免重复，我做了类似下面的事情

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: "" )  }

现在我想在我的双块中传递这个散列，但每当我这样做时我都会得到一个错误

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

Answer 1

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。
