ActionController::RoutingError: 未初始化的常量 Api::V1::ApiController [英] ActionController::RoutingError: uninitialized constant Api::V1::ApiController

问题描述

我有用于控制用户任务的 Rails 5 API 项目，但出现以下错误，但并非总是针对相同的控制器和路由.

I have Rails 5 API project for controlling user tasks and I have the following error but not always for the same controller and route.

ActionController::RoutingError: uninitialized constant Api::V1::ApiController

我向您描述了我的项目，以更详细地解释错误.

I describe you a little bit my project to explain in more detail the error.

应用结构

路线

scope module: 'api' do
  namespace :v1 do

    # => Login routes
    scope module: 'login' do
      match 'login', to: 'sessions#login', as: 'login', via: :post
    end

    # => Team routes
    scope module: 'team' do

      # => no admin routes
      resources :tasks, except: [:index] do
        collection do
          match ':view', to: 'tasks#index', as: 'tasks', via: [:get, :post]
        end
      end
    end

  end
end

API 控制器

module Api
  class ApiController < ApplicationController

    def respond_with_errors(object)
      render json: {errors: ErrorSerializer.serialize(object)}, status: :unprocessable_entity
    end

  end
end

团队负责人

module Api::V1
  class Team::TeamController < ApiController

任务控制器

module Api::V1
  class Team::TasksController < Team::TeamController

登录控制器

module Api::V1
  class Login::LoginController < ApiController

会话控制器

module Api::V1
  class Login::SessionsController < Login::LoginController

当我执行登录路由和任务路由之后，我在最后一个路由和团队模块中的所有路由中得到错误.如果我更改项目并保存它(只有一个空格)，然后我执行任务路由和登录路由后，我在最后一个路由和登录模块中的所有路由中得到错误.

When I execute login route and after tasks route, I get the error in last route and all the routes in team module. If I change the project and save it (only one blank space) and then I execute tasks route and after login route, I get the error in last route and all the routes in login module.

没有任何意义...

Rails 服务器出现此错误

推荐答案

继承时应该使用正确的常量 - ::Api::ApiController:

You should be using the right constant while inheriting - ::Api::ApiController:

module Api::V1
  class Team::TeamController < ::Api::ApiController

因为否则它正在搜索Api::V1::ApiController，但应该搜索Api::ApiController

because otherwise it is searching for Api::V1::ApiController, but should search for Api::ApiController
