我有一个简单的 Rails 应用程序，我正在尝试在其上添加活动源。为此，我正在使用 Public Activity Gem 并关注此Railscast
但现在它给了我一个错误：
undefined method `user_path' for #<#<Class:0x4a8b288>:0x4a90a30>
我的代码是：
活动控制器.rb
class ActivitiesController < ApplicationController
def index
@activities = PublicActivity::Activity.order("created_at desc")
end
end
我的活动 index.html.erb 文件
<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 %>
我的comment.rb 文件
class Comment < ActiveRecord::Base
include PublicActivity::Model
tracked owner: ->(controller, model) { controller && controller.current_user }
belongs_to :shipment
belongs_to :user
end
我的 routes.rb 文件
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
因此，如果有人可以帮助如何摆脱这种情况。提前致谢。
