ruby-on-rails - 为什么此 rails 形式找不到正确的路径？

Question

所以我一直把头撞在墙上，试图弄清楚为什么它不起作用。我不断

ActionView::Template::Error:
   undefined method `admin_information_index_path' for #<#<Class:0x007fc67971cab8>:0x007fc67d775740>

带有跟踪:

 # ./app/views/admin/informations/_form.html.erb:1:in `_app_views_admin_informations__form_html_erb__2815737811953353352_70245242566200'
 # ./app/views/admin/informations/new.html.erb:2:in `_app_views_admin_informations_new_html_erb___3700624853666844924_70245242606040'

任何正确方向的提示？

我的路线:

namespace :admin do
  resources :informations
end

我的 Controller :

class Admin::InformationsController < Admin::AdminController
  def new
    @information = Information.new
  end
end

views/admin/informations/new.html.erb:

<h1>Add New Information Page</h1>
<%= render :partial => 'form', locals: { information: @information } %>

views/admin/informations/_form.html.erb:

<%= form_for [:admin, information] do |f| %>
    <%= error_messages_for information %>

    <%= f.label :title %><br>
    <%= f.text_field :title %><br><br>

    <%= f.label :content %><br>
    <%= f.text_area :content %><br><br>

    <%= f.submit "Submit" %>
<% end %>

rake routes的输出

    admin_informations GET    /admin/informations(.:format)           admin/informations#index
                       POST   /admin/informations(.:format)           admin/informations#create
 new_admin_information GET    /admin/informations/new(.:format)       admin/informations#new
edit_admin_information GET    /admin/informations/:id/edit(.:format)  admin/informations#edit
     admin_information GET    /admin/informations/:id(.:format)       admin/informations#show
                       PUT    /admin/informations/:id(.:format)       admin/informations#update
                       DELETE /admin/informations/:id(.:format)       admin/informations#destroy
            admin_root        /admin(.:format)                        admin/sessions#new

Answer 1

尝试一下

<%= form_for information ,:namespace=>'admin' do |f| %>

更新:

查看您的路线“信息”是复数形式，但您使用的是单数形式的“信息”
