Ruby：通过foat字段对数组进行排序

Question

我有这段代码：

response = Place.all

    nearPlaces = []
    for el in response
      distance = el.distance_to([41.9097306,12.2558141])
      if distance < 20
        el.distance = distance
        nearPlaces.push(el)
      end
    end

    orderPlaces = nearPlaces.sort_by{|e| e[:distance]}

但阵列不是按距离提出的......任何建议？

Answer 1

nearPlaces.sort_by(&:distance)
