我已经设置了使用ransack gem在我的应用中搜索引脚的功能。我需要索引来仅渲染来自学校搜索的引脚。
编辑：添加routes.rb和rake路由输出

社团：
User.rb
has_many :pins
Pin.rb
belongs_to :user
School.rb
has_many :users
has_many :classrooms
has_many :pins, through: :users
pins_controller.rb
def search
index
render :index
authorize @pins
end
def index
@q = Pin.search(params[:q])
@pins = @q.result(distinct: true).order("created_at DESC").paginate(:page => params[:page], :per_page => 10 )
respond_with(@pins)
authorize @pins
end
销/ index.html.erb
此块工作正常，但显示数据库上的所有引脚，而不仅仅是属于学校的引脚。
<% @pins.each do |pin| %>
<% end %>
我试过，它在Pins #index
中给了我一条错误信息@school.pins.each
undefined method `pins' for nil:NilClass
学校/ show.html.erb
这是搜索表单
<%= f.search_field :user_name_cont, placeholder: "Search...", class: "form-control" %>
<% end %>
这里是routes.rb
中的搜索功能 resources :pins do
collection do
match 'search' => 'pins#search', via: [:get, :post], as: :search
end
end
编辑：Pin Schema
create_table "pins", force: true do |t|
t.integer "user_id"
t.text "question"
t.text "question2"
t.text "question3"
t.text "question4"
t.text "question5"
t.datetime "created_at"
t.datetime "updated_at"
t.text "question1"
t.integer "classroom_id"
t.string "sad"
t.string "mad"
t.string "brave"
t.string "embarrassed"
t.string "sorry"
t.string "frustrated"
t.string "left_out"
t.string "hurt"
t.string "confused"
t.string "worried"
t.string "proud"
t.string "other"
t.integer "sash_id"
t.integer "level", default: 0
end
我需要做些什么来限制仅显示属于该学校的引脚？
