Неопределенный метод `user_path'ошибка при добавлении Gem Public Activity

У меня есть простое приложение rails, и я пытаюсь добавить на него канал активности. Для этого я использую Gem Public Activity и следил за этим Railscast

но теперь это дает мне ошибку:

undefined method `user_path' for #<#<Class:0x4a8b288>:0x4a90a30>

Мои коды:

activities_controller.rb

class ActivitiesController < ApplicationController
  def index
    @activities = PublicActivity::Activity.order("created_at desc")
  end
end

Моя активность index.html.erb файл

<h1>feeds</h1>
<% @activities.each do |activity| %>
  <div class="activity">
    <%= link_to activity.owner.full_name, activity.owner if activity.owner %>
    added comment to <%= link_to activity.trackable.shipment.name.activity.trackable.shipment %>
    </div>
    <% end %>

Мой файл comment.rb

class Comment < ActiveRecord::Base
include PublicActivity::Model
 tracked owner: ->(controller, model) { controller && controller.current_user }
  belongs_to :shipment
  belongs_to :user
end

Мой файл rout.rb

Rails.application.routes.draw do

  get 'profiles/show'
  get 'pages/homepage'

  devise_for :users, :controllers => {:registrations => "registrations"}
  resources :shipments do
    member do
      get "like", to: "shipments#upvote"
    end
    resources :comments
  end
  # The priority is based upon order of creation: first created -> highest priority.
  # See how all your routes lay out with "rake routes".
  root "shipments#index"
  get '/:id', to: 'profiles#show'
  get 'activities/index'



  get "mailbox/inbox" => "mailbox#inbox", as: :mailbox_inbox
  get "mailbox/sent" => "mailbox#sent", as: :mailbox_sent
  get "mailbox/trash" => "mailbox#trash", as: :mailbox_trash
    resources :conversations do
    member do
      post :reply
      post :trash
      post :untrash
    end
  end
end

Так что если кто-то может помочь, как выйти из этого. Заранее спасибо.

Проблема с этим утверждением:

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

activity.owner это User объект и будет генерировать user_path ссылка (обычно /user/<owner_id>)

Я думаю тебе нужен

resources :users

линия в вашем config.rb (который, вероятно, должен быть завернут в authenticated :user do блок)

Дополнительная информация:

link_to call генерирует ссылку на страницу владельца активности.

Вам нужно, чтобы контроллер обслуживал страницу с информацией о владельце. Поскольку владелец User модель (вы написали devise_for :users), activity.owner это User объект.

когда link_to видит User объект, который он пытается вызвать user_path(owner.id) создать URL-адрес HTTP для этого пользователя. Чтобы это работало, вам нужен такой маршрут в вашем файле config.rb.

Когда вы добавляете resources :user линия к вашему config.routes и соответствующий UsersController (и просмотрите) вы создаете конечную точку HTTP для показа / создания / редактирования пользователей.

Я предлагаю вам просмотреть Railscast, объясняющий Devise.
