未定义的方法`user_path` public_activity with acts_as_follower

我仍然在学习Ruby on Rails，现在我被困在public_activity gem中。我当然知道，当我检查实例变量@activities时，该gem正在工作。未定义的方法`user_path` public_activity with acts_as_follower

活动视图：

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

活动控制器：

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

结果：

#<PublicActivity::Activity id: 2, trackable_id: 7, trackable_type: "Post", owner_id: 1, owner_type: "User", key: "post.create", parameters: {}, recipient_id: nil, recipient_type: nil, created_at: "2016-02-19 11:20:46", updated_at: "2016-02-19 11:20:46"> #<PublicActivity::Activity id: 1, trackable_id: 6, trackable_type: "Post", owner_id: nil, owner_type: nil, key: "post.create", parameters: {}, recipient_id: nil, recipient_type: nil, created_at: "2016-02-19 11:16:08", updated_at: "2016-02-19 11:16:08">

现在我想实际上显示，当用户决定跟随某人的活动。（使用acts_as_follower）

活动视图：

<% @activities.each do |activity| %> 
    <%= link_to activity.owner.email, activity.owner if activity.owner %> 
<% end %>

这就是当未定义的方法user_path出现。这是我的路线吗？

的routes.rb：

Rails.application.routes.draw do 

    resources :posts 
    resources :activities 

    devise_for :users 
    root 'page#index' 
    get '/users/:id' => 'page#profile' 
    get 'page/feed' 
    get 'page/home' 

    resources :page do 
    member do 
     get :follow 
     get :unfollow 
    end 
    end 
end

Post模型：

class Post < ActiveRecord::Base 
    include PublicActivity::Model 
    tracked owner: Proc.new{ |controller, model| controller.current_user } 

    belongs_to :user 
    mount_uploader :avatar, AvatarUploader 
end

注：我使用的设计作为我的用户认证

应用控制器：

class ApplicationController < ActionController::Base 
    include PublicActivity::StoreController 
    protect_from_forgery with: :exception 
end

其实这个问题来自于您的routes.rb文件。

因为activity.owner是User，所以您的看法其实是搜索user_path。

为了解决这个问题，你应该在你的路由文件中添加资源：

Rails.application.routes.draw do 

    resources :posts 
    resources :activities 
    resources :user 

    devise_for :users 
    root 'page#index' 
    get '/users/:id' => 'page#profile' 
    get 'page/feed' 
    get 'page/home' 

    resources :page do 
    member do 
     get :follow 
     get :unfollow 
    end 
    end 
end

我希望这将是有益的！

编辑： 我不好，错过了get '/users/:id' => 'page#profile'

这就给了你这样的输出：

 root GET /       page#index 
      GET /users/:id(.:format)   page#profile

所以，你应该设置手工路径是这样的观点：

<% @activities.each do |activity| %> 
    <%= link_to activity.owner.email, root_path(activity.owner_id) if activity.owner %> 
<% end %>

但仍然不是很好。最好在您的routes.rb文件中创建资源，并为您的用户模型设置适当的路线。

它的工作，但有一个错误。要访问用户配置文件，它现在是users/id，生成的链接是user/id，并引发未初始化的错误 – Raymond

更新 - 我通过移动底部的资源来修复它。 – Raymond

我的坏（这是星期五....）用途：资源：用户而不是：用户...对不起:) –
