Do rails rake tasks provide access to ActiveRecord models?（6个答案）
昨天关门了。
我正在尝试运行一个rake任务添加到我的数据库。但是我得到下面的错误。如果任何人有这个错误或知道解决方案，任何帮助将不胜感激!

rails aborted!
NameError: uninitialized constant User
/Users/richardbatt/Desktop/Ruby/NelsonParksProject/lib/tasks/users.rake:31:in `block (3 levels) in <main>'
/Users/richardbatt/Desktop/Ruby/NelsonParksProject/lib/tasks/users.rake:22:in `each'
/Users/richardbatt/Desktop/Ruby/NelsonParksProject/lib/tasks/users.rake:22:in `block (2 levels) in <main>'
/Users/richardbatt/Desktop/Ruby/NelsonParksProject/bin/rails:4:in `<main>'
Tasks: TOP => users:xero_users
(See full trace by running task with --trace)

namespace :users do
  desc "Gets Users from Xero"
  task :xero_users do

    require 'xero-ruby'

    creds = {
      client_id: '...',
      client_secret: '...',
      grant_type: 'client_credentials'
    }

    xero_client = XeroRuby::ApiClient.new(credentials: creds)

    @token_set = xero_client.get_client_credentials_token
    # save @token_set

    accessToken = @token_set["access_token"]

    users = xero_client.accounting_api.get_users('').users

    users.each do |user|

      userID = user.user_id
      userEmailAddress = user.email_address
      userFirstName = user.first_name
      userLastName = user.last_name
      userIsSubscriber = user.is_subscriber
      userOrganisationRole = user.organisation_role

      User.create(email: userEmailAddress)

    end

  end
end

我试图将新用户添加到我的数据库中。当我使用"User. create（email："测试"）"在我的家庭控制器中，它添加到数据库中。只是不是在我运行rake任务的时候。
谢谢你!
