我在将public_activity添加到我的rails应用程序时进展缓慢。
它正在运行，但我在调用正确的方法和链接时遇到问题，使其看起来很漂亮
当我的activities.index.html只有
时<% @activities.each do |activity| %>
<%= activity.inspect %>
<% end %>
在我看来，我可以看到
#<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">
当我的activities/index.html视图
<% @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 %>
错误是
undefined method `user_path'
这与我的路线有关吗？ routes.rb是
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

答案 0 :(得分：1)
您将获得未定义的方法user_path，因为路由文件不包含用户show view的路由。你必须创建一个才能工作。首先，您应该创建一个users_controller并在其中定义show方法。
class UsersController << ApplicationController
def show
@user = User.find(params[:id])
end
end
然后，在您的routes.rb文件中，您将要制作路线。
match '/users/:id', :to => 'users#show', :as => :user
：as参数告诉路由器将路由命名为什么（然后可以将_path或_url添加到：as参数中）。您想要调用此用户，因为当您直接链接到ActiveRecord模型（如用户）时，Rails会尝试将该模型转换为model_path。
答案 1 :(得分：0)
<%= link_to activity.owner.profile_name, activity.owner if activity.owner %>
表示activity.owner属于user类型，并链接到user_path（activity.owner）
尝试做一个rake路线。并查看用户#show是否已定义。
