public_activityRailsアプリへの追加の進行が遅いです。

それは機能していますが、見栄えを良くするために正しいメソッドとリンクを呼び出すのに問題があります

私の activities.index.html がちょうど

<% @activities.each do |activity| %>
    <%= activity.inspect %>
<% end %>

私の見解では、私は見ることができます

#<PublicActivity::ORM::ActiveRecord::Activity id: 2, trackable_id: 41, trackable_type: "Guideline", owner_id: 12, owner_type: "User", key: "guideline.create", parameters: {}, recipient_id: nil, recipient_type: nil, created_at: "2013-03-07 08:25:45", updated_at: "2013-03-07 08:25:45"> #<PublicActivity::ORM::ActiveRecord::Activity id: 1, trackable_id: 40, trackable_type: "Guideline", owner_id: nil, owner_type: nil, key: "guideline.create", parameters: {}, recipient_id: nil, recipient_type: nil, created_at: "2013-03-07 08:21:09", updated_at: "2013-03-07 08:21:09">

私のactivities/index.html見解があるとき

<% @activities.each do |activity| %>
    <div class="activity">
    <%= link_to activity.owner.profile_name, activity.owner if activity.owner %>
    added guideline to <%= link_to activity.trackable.guideline.title, activity.trackable.guideline %>
</div>
<% end %>

エラーは

undefined method `user_path'

これは私のルートと関係がありますか？ routes.rbは

    Guidelines::Application.routes.draw do

  get "activities/index"

  # get "user/index"

  ActiveAdmin.routes(self)

  devise_for :admin_user, ActiveAdmin::Devise.config


  get "guidelines/topic"
  get "guidelines/topichospital"
  get "guidelines/topicspecialty"
  get "guidelines/favourite"
  get "profiles/show"
  get "guidelines/show"


  devise_for :users

  devise_scope :user do
    get 'signup', to: 'devise/registrations#new', as: :register
    get 'login', to: 'devise/sessions#new', as: :login
    get 'logout', to: 'devise/sessions#destroy', as: :logout
    get 'edit', to: 'devise/registrations#edit', as: :edit
    put 'users' => 'devise/registrations#update', :as => 'user_registration'
    get 'about', to: 'about#about', as: :about
  end

  resources :guidelines
  get 'guidelines', to: 'guidelines#index', as: :guidelines
  get 'favourites', to: "favourites#show", as: :favourites
  get 'topics', to: 'guidelines#list', as: :topics
  get 'hospitals', to: 'guidelines#listhospital', as: :hospitals
  get 'specialties', to: 'guidelines#listspecialty', as: :specialties


 resources :activities

  root :to => 'guidelines#index'

end

user_pathルートファイルにユーザーshowビューのルートが含まれていないため、未定義のメソッドを取得しています。これを機能させるには、作成する必要があります。まず、users_controllerを作成し、その中でshowメソッドを定義する必要があります。

class UsersController << ApplicationController   
  def show
    @user = User.find(params[:id])
  end
end

次に、routes.rbファイルでルートを作成します。

match '/users/:id', :to => 'users#show', :as => :user

：asパラメーターは、ルーターにルートの名前を指定します（：asパラメーターが何であれ、_pathまたは_urlを追加できます）。ユーザーのようにActiveRecordモデルに直接リンクすると、Railsはそのモデルをmodel_pathに変換しようとするため、このユーザーを呼び出す必要があります。

<%= link_to activity.owner.profile_name, activity.owner if activity.owner %>

activity.owner はタイプ user であり、user_path(activity.owner) へのリンクであると言います

レーキルートをやってみてください。user#show が定義されているかどうかを確認します。
