我正在尝试将一个网页从我的rails 4应用程序保存到磁盘,使用
send_data(render_to_string, :filename => "foo.html").
send_data(render_to_string,:filename =>“foo.html”)。
The file is saved alright, but the css is missing.
文件保存正常,但缺少css。
I tried adding the type attribute, like so:
我尝试添加type属性,如下所示:
send_data(render_to_string, :filename => "foo.html", :type => "text/html")
send_data(render_to_string,:filename =>“foo.html”,:type =>“text / html”)
but it didn't help.
但它没有帮助。
How can I save the file with all the css (and other assets potentially), so that if I click on the saved file I'll see the same thing that I attempted to save?
如何使用所有css(以及其他可能的资产)保存文件,这样如果我点击保存的文件,我会看到我试图保存的相同内容?

render_to_string renders only the html part. That returns exact the same string like the browser receives when he loads a html page. Stylesheets and other assets will be loaded in additional requests. Therefore I only see one possible way: render_to_string a html layout with all assets inlined.
render_to_string只呈现html部分。这会返回与浏览器加载html页面时收到的完全相同的字符串。样式表和其他资产将在其他请求中加载。因此,我只看到一种可能的方式:render_to_string一个内联所有资产的html布局。
An other option might be to open the save as dialog with Javascript. But there seems no standardized way to do so.
另一个选项可能是使用Javascript打开另存为对话框。但似乎没有标准化的方法。

You need to use some crawler to get the page with all assets and then gzip and send the result.
您需要使用一些爬虫来获取包含所有资源的页面,然后gzip并发送结果。
