嵌套资源/控制器/视图

Question

公寓管制员：

@appartment = Appartment.find(params[:id])
@amenities = @appartment.amenities

模特公寓：

has_many :amenity_appartment
has_many :amenities, :through => :amenity_appartment

模型舒适性

has_many :amenity_appartment
has_many :appartments, :through => :amenity_appartment
belongs_to :category_amenity

Model CategoryAmenity

has_many :amenities

为了展示公寓的设施，我有这个：

<% @amenities.each do |amenity| %>
    <p><%= amenity.name %></p>

我得到了所有设施的清单，但我可以将其与category_amenity的名称分开吗？

Answer 1

您应该先在控制器中按类别对设施进行分类：

@amenities = {}
@appartment.amenities.each do |a|
  @amenities[a.category_amenity.name] ||= []
  @amenities[a.category_amenity.name] << a
end

并向他们展示：

<% @amenities.each do |category_name, vals| %>
    <p><%= category_name %></p>
    <% vals.each do |amenity| %>
      ....
