Ruby on rails 4 rails 4 iframe路由错误,ruby-on-rails-4,iframe,coffeescript,Ruby On Rails 4,Iframe,Coffeescript,我遵循这一点只是为了了解有关实现coffeescript的更多信息我的模型是 class Url < ActiveRecord::Base validates :url, presence: true end app/views/layouts/application.rb <!DOCTYPE html> <html> <head> <title>Shorty</title> <%= stylesheet

我遵循这一点只是为了了解有关实现coffeescript的更多信息

我的模型是

class Url < ActiveRecord::Base

  validates :url, presence: true

end

app/views/layouts/application.rb

<!DOCTYPE html>
<html>
<head>
  <title>Shorty</title>
  <%= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track' => true %>
  <%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
  <%= csrf_meta_tags %>
</head>
<body>

<% if flash[:shortened_id].present? %>
  <p class='shortened-link'>
    The shortened url is available <%= link_to 'here',
url_url(flash[:shortened_id]) %>.
    (Right click and copy link to share it).
  </p>
<% end %>


<%= yield %>

</body>
</html>

错误是

没有与[GET]/url/www.rte.ie匹配的路由

我假设正在执行coffeescript，因为上面的地址是我在文本框中输入的url，而iframe在提供url之前是不可见的

您似乎需要将协议添加到url，否则在show action中将\u重定向到@shorted\u url.url时重定向将不起作用。在您的模型中，您可以通过以下方式进行保存：

class Url < ActiveRecord::Base
  before_save :ensure_protocol

  private

  def ensure_protocol
    self.url = "http://#{url}" unless url_protocol_present?
  end

  def url_protocol_present?
    u = URI.parse(url)
    u.scheme
  end
end

另外，我认为您的新操作中有一个输入错误：重定向到语句中的新url是什么？

谢谢，您的回答修复了url的保存，它让我了解了如何修复iframe问题，此修改后的咖啡脚本适用于$document.ready->preview=$preview url$'url\'url'.keyup->current\'value='http://'+$.trim@value（如果当前\'u值为preview.hide.attr'src'，否则为preview.show.attr'src'，current \'u值）

<!DOCTYPE html>
