Question

我遇到了问题。经过一个小时的搜索，我仍然在解决这个问题。我在这里经历了大多数问题，但没有一个对我有用。感觉就像我错过了一些简单的事情。

这是我的错误

ActionView::Template::Error (undefined method `client_infos_path' for # 
.  <#<Class:0x007fda7a69b160>:0x007fda7a6994a0>
Did you mean?  client_session_path
           client_path
           clients_path):
   1: <h2>Add <%= current_user.username%> info</h2>
   2:
   3: <%= form_for @client_info do |f| %>
   4:   <div class="field">
   5:     <%= f.label :company_size, 'Company Size' %> <br />
   6:     <%= f.text_field :company_size %>

app/views/client_infos/new.html.erb:3:in 
app_views_client_infos_new_html_erb__493536261245691520_70288166673800'

这是我的控制人

class ClientInfosController < ApplicationController
  before_action :authorize_user

  def new
   # binding.pry
   @client_info = ClientInfo.new
   @client = Client.find(params[:client_id])
  end

还有我的routes.rb

resources :clients do
  resources :projects
  resources :client_infos, only: [:new, :create]
end

提前谢谢

Answer 1

ActionView :: Template :: Error（未定义的方法“ client_infos_path”用于

您在client_infos下有clients的嵌套资源，因此没有适合您的路由。您需要更改

<%= form_for @client_info do |f| %>

到

<%= form_for [@client, @client_info] do |f| %>

提示：

运行rake routes。它将列出所有可用的路线。

如果您在控制台中执行rake routes，则会得到：

        client_projects GET    /clients/:client_id/projects(.:format)              projects#index
                        POST   /clients/:client_id/projects(.:format)              projects#create
     new_client_project GET    /clients/:client_id/projects/new(.:format)          projects#new
    edit_client_project GET    /clients/:client_id/projects/:id/edit(.:format)     projects#edit
         client_project GET    /clients/:client_id/projects/:id(.:format)          projects#show
                        PATCH  /clients/:client_id/projects/:id(.:format)          projects#update
                        PUT    /clients/:client_id/projects/:id(.:format)          projects#update
                        DELETE /clients/:client_id/projects/:id(.:format)          projects#destroy
    client_client_infos POST   /clients/:client_id/client_infos(.:format)          client_infos#create
 new_client_client_info GET    /clients/:client_id/client_infos/new(.:format)      client_infos#new
                clients GET    /clients(.:format)                                  clients#index
                        POST   /clients(.:format)                                  clients#create
             new_client GET    /clients/new(.:format)                              clients#new
            edit_client GET    /clients/:id/edit(.:format)                         clients#edit
                 client GET    /clients/:id(.:format)                              clients#show
                        PATCH  /clients/:id(.:format)                              clients#update
                        PUT    /clients/:id(.:format)                              clients#update
                        DELETE /clients/:id(.:format)                              clients#destroy

如您所见，您没有client_infos路径，因为client_infos嵌套在clients下。相反，您有client_client_infos-考虑到您的routes.rb应该做的。您也可以这样做（如2.9 Creating Paths and URLs From Objects中所述）：

<%= form_for [@client, @client_info] do |f| %>

Rails会推断您要使用client_client_infos命名的路由。

不断收到NoMethodError
