设计邀请测试 default_url_options答案

【问题标题】：Devise Invitable testing default_url_options设计邀请测试 default_url_options

【问题描述】：

我正在测试该方法 User.invite!(:email => "new@example.com")

Devise Invitable 的 rspec 但我收到以下错误：

ActionView::Template::错误：缺少要链接的主机！请提供 :host 参数，设置 default_url_options[:host]，或设置 :only_path 为 true

我已经在我的 config/test.rb

中添加了这一行

config.action_mailer.default_url_options = { :host => 'localhost:3001' }

我必须做些什么来解决这个问题？

我的 Rails 版本：3.2.14

编辑这是我的 test.rb 文件

MyApp::Application.configure do
  # Settings specified here will take precedence over those in config/application.rb

  # The test environment is used exclusively to run your application's
  # test suite. You never need to work with it otherwise. Remember that
  # your test database is "scratch space" for the test suite and is wiped
  # and recreated between test runs. Don't rely on the data there!
  config.cache_classes = true

  # Configure static asset server for tests with Cache-Control for performance
  config.serve_static_assets = true
  config.static_cache_control = "public, max-age=3600"

  # Log error messages when you accidentally call methods on nil
  config.whiny_nils = true

  # Show full error reports and disable caching
  config.consider_all_requests_local       = true
  config.action_controller.perform_caching = false

  # Raise exceptions instead of rendering exception templates
  config.action_dispatch.show_exceptions = false

  # Disable request forgery protection in test environment
  config.action_controller.allow_forgery_protection    = false

  # Tell Action Mailer not to deliver emails to the real world.
  # The :test delivery method accumulates sent emails in the
  # ActionMailer::Base.deliveries array.
  config.action_mailer.delivery_method = :test

  # Raise exception on mass assignment protection for Active Record models
  #config.active_record.mass_assignment_sanitizer = :strict

  # Print deprecation notices to the stderr
  config.active_support.deprecation = :stderr

  config.action_mailer.default_url_options = { :host => 'localhost:3001' }
end

【问题讨论】：

您能发布您的test.rb 的样子吗？此外，您可能需要包含config.action_mailer_delivery_method。
我做了，用 test.rb 内容编辑了我的帖子

【解决方案1】：

我找到了这个解决方案，承认它有点老套，但至少有效，如果有人找到更清洁的解决方案，请随时发表评论。

将此添加到我的 application_controller.rb

before_filter :set_host_from_request

private

    def set_host_from_request
        ActionMailer::Base.default_url_options = { host: request.host_with_port }
    end
