Question

我正在尝试创建一个create_indexes rake任务，用于在我的应用程序中为MongoDb记录创建索引。我在我的应用程序的顶层目录中有Rakefile，代码如下。

require "./app"
set :database_file, "./config/mongoid.yml"
Dir.glob('lib/tasks/*.rake').each { |r| load r}

我在我的应用程序的lib / tasks文件夹中创建了一个db.rake文件

namespace :db do
task :create_indexes => :environment do
#
    begin
        Rails.application.eager_load!
    rescue Object => e
    end
#
    begin
        Bundler.require(:default, :assets, 'production')
    rescue Object => e
    end
#
    to_index_models = [] 

    ObjectSpace.each_object(Module) do |object|
        begin
            to_index_models.push(object) if object.respond_to?(:create_indexes)
        rescue Object => e
            warn "failed on: #{ object }.respond_to?(:create_indexes)"
        end
    end
#
    to_index_models.sort! do |a, b|
        begin
            a.name <=> b.name
        rescue Object
            0
        end
    end
#
    begin
        to_index_models.uniq!
    rescue Object
    end
#
    to_index_models.each do |model|
        begin
            model.create_indexes
            puts "indexed: #{ model }"
        rescue Object => e
            warn "failed on: #{ model }#create_indexes"
        end
    end
end
end

这取自http://grokbase.com/t/gg/mongoid/12akaq1na7/equivalent-of-create-indexes-rake-task-in-non-rails-environment#20121106gzwpoiifznpdxa3ugtzdvjgplq

我的mongoid.yml文件是localhost文件的基本连接：

development:
  sessions:
    default:
      database: mongoid
      hosts:
        - localhost:27017

但每当我尝试将rake任务运行为：

rake db:create_indexes[development]

我收到以下错误：
