将控制器存储在子文件夹中时的名称错误未初始化常量

Question

我正在构建的JSON API在命名空间API和V1下有一组路由（所有路由都以API/V1开头。我现在正在创建一组新的控制器和模型，它们都链接到"关联"的"概念"，因此我决定将它们存储在我的文件夹"控制器"和"模型"内的子文件夹"关联"中。我还为相对于这些控制器的路由创建了一个新的命名空间"关联"。

我一直在尝试在办公室控制器的创建操作上发布，但我得到这个：

Started POST "/api/v1/association/account_assos/1/offices" for ::1 at 2016-04-26 13:54:00 +0200
Processing by Api::V1::Association::OfficesController#create as JSON
  Parameters: {"office"=>{"name"=>"Samu Paris", "contact_mail"=>"[e-mail]", "contact_phone"=>"[phone]", "address"=>"148 BD BINEAU", "city"=>"PARIS", "postcode"=>"92200", "photos_attributes"=>[{"image_url"=>""}]}, "account_asso_id"=>"1"}
  User Load (1.0ms)  SELECT  "users".* FROM "users" WHERE "users"."email" = $1  ORDER BY "users"."id" ASC LIMIT 1  [["email", "[e-mail]"]]
Completed 500 Internal Server Error in 50ms (ActiveRecord: 1.0ms)
**NameError - uninitialized constant Api::V1::Association::OfficesController::Association:**

我的路线看起来像：

namespace :api, defaults: { format: :json } do
      namespace :v1 do
        namespace :association do
          resources :account_assos, only: [ :index, :show, :update, :create ] do
            resources :offices, only: [ :index, :show, :create ]
          end
        end
      end
    end

和有问题的控制器：

class Api::V1::Association::OfficesController < Api::V1::BaseController
  before_action :set_office, only: [ :show, :update, :destroy]
  before_action :set_account_asso, only: [:create, :index]

  def index
    # is this the best way ??
    if (current_user.created_account_asso == @account_asso) || ((current_user.account_asso == @account_asso) && (current_user.status == "manager"))
      @offices = policy_scope(office).where(account_asso: @account_asso)
      render :index
    else
      render json: {message: "Unauthorized"}
    end
  end
  def show
    authorize @office
  end
  def update
    authorize @office
    if @Office.update(office_params)
      render :show
    else
      render_error
    end
  end
  # input account
  def create
    @office = @account_asso.offices.build(office_params)
    authorize @office
    if @office.save
      render :show
    else
      render_error
    end
  end
  def destroy
    authorize @office
    if @office.destroy
      render json: {success: "Office successfully destroyed"}
    else
      render json: {error: "There was an error please try again"}
    end
  end
  private
  def set_account_asso
    @account_asso = Association::AccountAsso.find(params[:account_asso_id])
  end
  def set_office
    @office = Office.find(params[:id])
  end
  def Office_params
    params.require(:office).permit( :name,
                                    :address,
                                    :contact_mail,
                                    :contact_phone,
                                    :address,
                                    :city,
                                    :postcode,
                                    photos_attributes: [ :image_url ]
                                  )
  end
  def render_error
    render json: { errors: @office.errors.full_messages }, status: :unprocessable_entity
  end
end

offices_controller存储在 api/v1/association 中，这对我来说似乎是一致的。为什么我会得到

  **NameError - uninitialized constant Api::V1::Association::OfficesController::Association:** 

我相对于"关联"概念的模型存储在模型/关联中。这是我的AccountAsso模型，例如（models/association/account_asso.rb）：

class Association::AccountAsso < ActiveRecord::Base
  # associations
  has_many :users, dependent: :destroy
  has_many :offices, dependent: :destroy
  belongs_to :admin, class_name: "User", foreign_key: "admin_user_id"

  # validations
  validates :name, presence: true, length: {minimum: 2}
  validates_format_of :contact_mail,:with => Devise::email_regexp
  validates :contact_tel, format: {
      with:     /A(+33)[1-9]([-. ]?[0-9]{2}){4}z/,
      message:  'Le format de votre numéro doit être du type [phone]'
    }
  validates :iban, presence: true, format: {
      with:     /A[a-zA-Z]{2}d{2}s*(w{4}s*){2,7}w{1,4}s*z/,
      message:  'Le format de votre IBAN doit être du type FR70 3000 2005 5000 0015 7845 Z02'
    }, allow_blank: true
  validates :bic, presence: true, format: {
      with:     /([a-zA-Z]{4}[a-zA-Z]{2}[a-zA-Z0-9]{2}([a-zA-Z0-9]{3})?)/,
      message:  'Le format de votre BIC doit être du type AXABFRPP  '
    }, allow_blank: true
  validates :admin, presence: true, uniqueness: true

  # validates :legal_status, presence: true,
end

Answer 1

由于在该

路径控制器找不到父常量Association，请使用完整路径Api::V1::Association，或相对一个类方法::parent：

@account_asso = Api::V1::Association::AccountAsso.find(params[:account_asso_id])

或

@account_asso = parent::AccountAsso.find(params[:account_asso_id])

好吧，由于AccountAsso是一个模型，它的声明应该从命名空间根开始考虑，因为它们不是服务于子系统的 rails 等的一部分。当然，您可以有子模型，但它们应该属于父模型，而不是另一个，因此：

app/models/account_asso.rb

class AccountAsso < ActiveRecord::Base ;end

和子模型：

app/models/account_asso/new_asso.rb

class AccountAsso::NewAsso < AccountAsso ;end

或：

app/models/account_asso/otherm.rb

class AccountAsso::Otherm < ActiveRecord::Base ;end

注意：模型名称必须与模型文件的路径一致，否则导轨无法正确拾取它。

查看URL，它也具有错误的名称，而不是办公室，而是您正在呼叫办公室。

是否重新启动了服务器？此外，您的association文件夹应位于以下路径：app/controllers/api/v1/association/
