Question

我想在rake任务上获得渲染字符串。但像new_book_url这样的网址没有主机..

# on rake
controller = ApplicationController.new.tap do |controller|
  controller.request  = ActionDispatch::Request.new({})
end
p controller.render_to_string('books/index', layout: nil) #=> "<a href=\"http://:/books/new\">New Book URL</a>\n"
p Rails.application.config.action_mailer[:default_url_options] #=> {:host=>"localhost", :port=>3000}
p Rails.application.routes.default_url_options #=> {}

# books/index
<%= link_to 'New Book URL', new_book_url %>

当我设置Rails.application.routes.default_url_options = Rails.application.config.action_mailer[:default_url_options]时，它不起作用......

您需要添加default_url_options作为控制器的实例方法：

controller = ApplicationController.new.tap do |controller|
  controller.request  = ActionDispatch::Request.new({})
  def controller.default_url_options
    host = {'production' => 'production.example.org', 'development' => 'development.example.org'}[Rails.env]
    {host: host}
  end
end
p controller.render_to_string('books/index', layout: nil)

如何在rake上设置默认主机？
