'block in draw' 轨道 6 条路线

如何解决'block in draw' 轨道 6 条路线

在移动到 rails 6 后，我试图将我的路线拆分为不同的文件，我已经检查了文档并完成了以下操作：

Rails.application.routes.draw do
  root 'summary#index'

  draw(:general)
end

在`api_schema_controller 中

module Api
  module V1
    class ApiSchemaController < ApplicationController
      CONTROLLER_NAMES = %w(SalesOrders VatRates VatTypes Companies ExchangeRates Auth Products BankAccounts Locations Customers
             SalesInvoices Receipts Accounts BudgetModels)

      require_relative '../../../../lib/internal_apI/Open_api_builder'

      def self.build_route_for_action(routing_object,controller_name,controller_class,action_name,action_conf)
        path = ApiSchemaController.action_path(controller_class,action_conf,true)
        verb = action_conf[:verb].present? ? action_conf[:verb].to_s : 'get'

        routing_object.send(verb,path,action: action_name,controller: controller_name.underscore)
      end

      def self.build_routes(routing_thing)
        unless ActiveRecord::Migrator.needs_migration?
          self::CONTROLLER_NAMES.each do |controller_name|
            module_root = self.module_root
            controller_class = (module_root + '::' + controller_name + 'Controller').constantize

            controller_class::ACTIONS.each do |action_name,action_conf|
              self.build_route_for_action(routing_thing,action_conf.deep_dup)
            end
          end
        end
      end

      def self.module_root
        self.to_s.gsub(/::[^:]*$/,'') # not super sure about this reg ex,maybe splitting would be better
      end

      def open_api
        controller_names = self.class::CONTROLLER_NAMES
        if params[:only_controllers].present?
          only = params[:only_controllers].split(',')
          controller_names = only.select { |c| c.in?(controller_names) }
        end

        module_root = self.class.module_root
        schema_builder = OpenApiBuilder.new

        controller_names.each do |controller_name|
          schema_builder.add_paths_from_controller_class(
              (module_root + '::' + controller_name + 'Controller').constantize
          )
        end

        render json: schema_builder.to_json
        # render text: schema_builder.to_yaml,content_type: 'text/yaml'
      end

      def get_node_test_result
        dir = File.expand_path('../../../../../node',__FILE__)
        render json: `node #{dir}/index.js`
      end

      protected

      def self.action_path(controller_class,for_route = false)
        path = '/' + controller_class.controller_name.gsub('_','-')
        path += action_conf[:path] unless action_conf[:path].blank?
        path = path.gsub(/{(.*?)}/,':\1') if for_route

        path
      end
    end
  end
end

在 config/routes/general.rb 我有以下内容

# api routes
namespace :api do
  namespace :v1 do
    get 'ping',action: :ping,controller: 'summary'
    get 'version',action: :version,controller: 'summary'

    delete 'sign_out',action: :sign_out,controller: 'authenticate'
    Api::V1::ApiSchemaController.build_routes(self)
  end
end

但是，我在启动服务器时收到以下信息

我不知道错误是什么，因为我已经遵循了文档，但我这似乎是 api 生成路由的方式，而不是我的代码，我只是不确定重构它的最佳方法。

解决方法

错误 undefined method 'needs_migration?' for ActiveRecord::Migrator:Class (NoMethodError) 被抛出，因为方法 needs_migration? 属于 ActiveRecord::MigrationContext 而不是 ActiveRecord::Migrator

试试这个

# api_schema_controller
# ...
def self.build_routes(routing_thing)
 unless ActiveRecord::Base.connection.migration_context.needs_migration?
#...
