rails 部署后页面布局乱掉了

yldcb — Sat, 21 Mar 2015 14:04:48 +0800

经过两天折腾，终于是部署好了但是有个问题，部署后它把所有 css 都打包成一个文件，导致整个布局就乱掉了，这个改如何解决？

We're sorry, but something went wrong.

We've been notified about this issue and we'll take a look at it shortly.

google 了半天没有解决办法，希望以前遇到过这类问题的大牛能给个方案。

phantomjs 在 rails 里面使用问题？

yldcb — Thu, 25 Dec 2014 19:36:24 +0800

想做截图功能因为找了很久没找到相关例子，虽然引用了 phantomjs gem 但是不知道怎么使用。后来想了个傻办法，shell 执行命令在 main controller 我是这么写的： require 'pathname' class MainController < ApplicationController def index path = Pathname.new(File.dirname(FILE)).realpath + "../../public" url = "http://www.baidu.com" img = "hello.png" exec = "#{path}" + "/phantomjs #{path}/exec.js #{url} #{img}" system "#{exec}" puts "ok"

end end 但是不执行。不知道什么原因希望用过 phantomjs 的能够指点一下，非常感激

代码是直接从 github 下过来解压然后 bundle install 发现 rails s 后能正常运行但是测试就是各种出现错误 bundle exec rspec spec/requests/user_pages_spec.rb -e "signup page" 执行这句的时候出现：
