如何将数组传递给具有其他名称的部分

Question

我有一个模型，分别用于汽车，卡车，公共汽车，货车等，我将它们列在自己的控制器和视图中：

汽车index.html.slim

- if @cars.present?
  .pagination.justify-content-center
    = will_paginate @cars
  - else
    = t "search.sorry_no_results"

Trucks index.html.slim

- if @trucks.present?
  .pagination.justify-content-center
    = will_paginate @trucks
  - else
    = t "search.sorry_no_results"

以及公共汽车，货车等等。

我想把那个重复的块变成局部的。但是，我无法将@cars @trucks传递到@vehicles数组，以便所有这些模型可以共享该部分：

汽车指数

= render partial: "pagination", collection: @cars, as: :vehicles

_pagination.html.slim

- if vehicles.present?
  .pagination.justify-content-center
    = will_paginate vehicles
- else
  = t "search.sorry_no_results"

我的解决方案

由于我不想要逐项列出数组，我的简单解决方案只是传递所有数组：

_pagination.html.slim

.pagination.justify-content-center
  - if @cars.present?
    = will_paginate @cars
  - elsif @trucks.present?
    = will_paginate @trucks
  - elsif @buses.present?
    = will_paginate @buses
  - elsif @vans.present?
    = will_paginate @vans
  - elsif @...
    ...
  - else
    = t "search.sorry_no_results"
