如何在 Ruby Sunspot 中定义动态作用域？

我想通过“所有”过滤器或“任何”过滤器来搜索曲目。所以这就是我得到的：

tracks_controller.rb

def search
  if params[:scope] == "any_of"
    Track.search do
      any_of do
        with(:name, "Thriller")
        with(:artist, "Michael Jackson")
      end

      with(:user_id, current_user.id)
    end
  elsif params[:scope] == "all_of"
    Track.search do
      all_of do
        with(:name, "Thriller")
        with(:artist, "Michael Jackson")
      end

      with(:user_id, current_user.id)
    end
end

它按预期工作。但如何重构代码使其变得 DRY 呢？

I want to search the tracks either by "all of" the filters, or by "any of" the filters. So here is what I got:

tracks_controller.rb

def search
  if params[:scope] == "any_of"
    Track.search do
      any_of do
        with(:name, "Thriller")
        with(:artist, "Michael Jackson")
      end

      with(:user_id, current_user.id)
    end
  elsif params[:scope] == "all_of"
    Track.search do
      all_of do
        with(:name, "Thriller")
        with(:artist, "Michael Jackson")
      end

      with(:user_id, current_user.id)
    end
end

It works as expected. But how to refactor the code to make it DRY?

这是先生：

def search
  Track.search do

    mode = (params[:scope] == 'any_of' ? method(:any_of) : method(:all_of)) # don't use method(params[:scope]) for obvious security reason)

    mode.call do
      with(:name, "Thriller")
      with(:artist, "Michael Jackson")
    end

    with(:user_id, current_user.id)
  end
end

Here it is Sir:

def search
  Track.search do

    mode = (params[:scope] == 'any_of' ? method(:any_of) : method(:all_of)) # don't use method(params[:scope]) for obvious security reason)

    mode.call do
      with(:name, "Thriller")
      with(:artist, "Michael Jackson")
    end

    with(:user_id, current_user.id)
  end
end
