collection/showページにおいて画像をクリックするとそれに紐づくitem/show(rails routes→/items/:id(.:format) )へ遷移したい。

#実現したい事
collection/showページにおいて画像をクリックするとそれに紐づくitem/show(rails routes→/items/:id(.:format) )へ遷移したい。

##現在
エラー表示がされる
ActiveRecord::RecordNotFound in CollectionsController#show
Couldn't find Item with 'id'=26

collectionにはid:26はありますがitemにはない状況です。

よろしくお願いいたします。

routes.rb

Rails.application.routes.draw do
  devise_for :users
  root 'pages#index'
  get "pages/show/:article_id", to: "pages#show"
  resources :collections
  resources :items
  resources :users, only:[:index, :show] do
    member do
      get :following, :followers
    end
  end
  resources :relationships, only: [:create, :destroy]
  get "items/:id" => "items#show"
  get "collections/:id" => "collections#show"
end

collections/showのview

<div class= "container">
  <div class= "logo_wrapper">
    <%= link_to image_tag('logo.png', alt:"positive-learning", class: "service_logo"), '/' %>
  </div>
  <div class= "collection_wrapper">
    <%= link_to item_path(@item) %>
      <%= @collection.image %>
      <%= @collection.explanation %>
  </div>
</div>
