设计和独角兽的奇怪错误
我在开发过程中使用了许多我的rails应用程序，我每天都会遇到这些错误1-2次

，唯一的解决方案是
sudo service unicorn_myapp stop
然后再次启动它
sudo service unicorn_myapp start
我检查了我的用户模型和相关模型的回调，但一切都运行正常，重新启动独角兽之后注册工作非常好，正如我之前所说的
我使用的是ruby 2.1.5和rails 3.2.21
这里也是我的gem文件

她是我的路线.rb
myApp::Application.routes.draw do namespace :api, defaults: { format: "json" } do devise_scope :user do post 'users' => 'registrations#create', :as => 'user_registration' post 'users/sign_in' => 'sessions#create', :as => 'user_session' get '/users/sign_out' => 'sessions#destroy' end devise_for :users, :controllers => {:sessions=>"sessions", :registrations => "registrations", :passwords => "passwords" ,:omniauth_callbacks=>"omniauth_callbacks"} ##etc... end
我的注册controller.rb
class RegistrationsController < Devise::RegistrationsController before_filter :prepare_for_mobile respond_to :js ,:html def create build_resource(sign_up_params) #resource.skip_confirmation! resource_saved = resource.save yield resource if block_given? if resource_saved if resource.active_for_authentication? set_flash_message :notice, :signed_up if is_flashing_format? sign_up(resource_name, resource) respond_with resource, location: after_sign_up_path_for(resource) else set_flash_message :notice, :"signed_up_but_#{resource.inactive_message}" if is_flashing_format? expire_data_after_sign_in! respond_with resource, location: after_inactive_sign_up_path_for(resource) end else clean_up_passwords resource @validatable = devise_mapping.validatable? if @validatable @minimum_password_length = resource_class.password_length.min end respond_with resource end end def update self.resource = resource_class.to_adapter.get!(send(:"current_#{resource_name}").to_key) prev_unconfirmed_email = resource.unconfirmed_email if resource.respond_to?(:unconfirmed_email) resource_updated = update_resource(resource, account_update_params) yield resource if block_given? if resource_updated if is_flashing_format? flash_key = update_needs_confirmation?(resource, prev_unconfirmed_email) ? :update_needs_confirmation : :updated set_flash_message :notice, flash_key end sign_in resource_name, resource, bypass: true respond_with resource, location: after_update_path_for(resource) else clean_up_passwords resource respond_with resource end end protected def after_sign_up_path_for(resource) step2_path end end

我不确定错误究竟是什么，但是通过查看gem源代码， def polymorphic_url方法，
（ actionpack-4.1.5/lib/action_dispatch/routing/polymorphic_routes.rb
# -- some code inflection = if options[:action] && options[:action].to_s == "new" args.pop :singular elsif (record.respond_to?(:persisted?) && !record.persisted?) args.pop :plural elsif record.is_a?(Class) args.pop :plural else :singular end
看起来，你的resource对象变成了集合或User.new ，然后变成:plural并给你那个错误。 我的猜测是尝试调试那个方向，HTH
