public_activity rails undefined方法user_path
我正在慢慢地将public_activity添加到我的rails应用程序中。
它正在工作，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刚刚有
在我看来，我可以看到
# #
当我的activities/index.html视图有
added guideline to
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
跑耙路线给了我

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。 您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routes.rb文件中，您将要创建路径。
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。
<%= link_to activity.owner.profile_name, activity.owner if activity.owner %>
说activity.owner是user类型并链接到user_path（activity.owner）
尝试做一个耙路线。 并查看是否定义了用户#show。
