Question

此应用程序基于Devise 3.0和Rails 4.1构建我有一个User对象，通过STI有两个子类（Lender和Business）。在企业注册并确认其电子邮件地址后，它们将被重定向到表单以填写有关自己的更多信息（此数据存储在名为SuppForm的新对象中）。业务对象has_one supp_form。当商家确认他们的电子邮件并被重定向到表单时，我收到错误。

错误

ActionController::RoutingError (uninitialized constant SuppFormsController)

routes.rb （我使用[]作为商业路线，因为我不希望它们与应用程序其他地方使用的路线重叠）

# User type routes, needed to define specific sign out route to allow get request, not delete request
  devise_for :users, skip: :registrations do get '/users/sign_out' => 'devise/sessions#destroy' end
  devise_for :lenders, skip: :sessions, :controllers => {:registrations => "lenders/registrations"}
  devise_for :businesses, skip: :sessions, :controllers => {:registrations => "businesses/registrations"}

  resources :businesses, :only => [] do
    resource :supp_form
  end

business.rb

class Business < User
  has_one :supp_form
  accepts_nested_attributes_for :supp_form
end

supp_form.rb

class SuppForm < ActiveRecord::Base
  belongs_to :business
end

supp_form_controller.rb

class SuppFormController < ApplicationController
    before_filter :authenticate_user!

    def new
      @suppform = SuppForm.new
    end 

    private

    def supp_form_params
      params.require(:supp_form).permit(:first_name, :last_name, :work_phone_number, :business_address, :business_postal_code)
    end
end

application_controller.rb

class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception

  def account_url
    return new_user_session_url unless user_signed_in?
    case current_user.class.name
    when "Business"
      business_root_path
    when "Lender"
      lender_root_path
    else
      root_path
    end if user_signed_in?
  end

  def after_sign_in_path_for(resource)
    if resource.sign_in_count == 1 && resource.type == "Business"
      new_business_supp_form_path(resource.id)
    else 
      stored_location_for(resource) || account_url 
    end 
  end

您可以在application_controller.rb中看到我根据他们登录的次数将业务重定向到supp_form。我还尝试通过调用resource.id来传递业务的ID。通过请求传递。收到错误时的网址是：http://xxxxxxxxxx/businesses/14/supp_form/new

看起来像是一个复数问题。将控制器更改为复数名称。

class SuppFormsController < ApplicationController
    before_filter :authenticate_user!
    # etc
end

听起来很奇怪，因为控制器只生成了一个supp_form。您还可以尝试设置变形以防止rails尝试复数supp_form中的单词config/initializers/inflections.rb

ActiveSupport::Inflector.inflections do |inflect|
   inflect.uncountable %w( supp_form )
end

确认后形成未初始化的常量错误
