我们正在从Rails 4.2.5升级到5.0.0.beta1

在测试时,我们希望看到像以前一样使用分页链接呈现的索引视图.但是我们现在得到一个ArgumentError错误页面,例如:

ArgumentError in Transactions#index 
/app/views/kaminari/_paginator.html.erb where line #10 raised:


<%= paginator.render do -%>

Generating an URL from non sanitized request parameters is insecure!

kaminari提出了一个问题

进一步研究这里是新的Rails 5.0.0.beta1代码,现在抛出错误:

将它添加到config/application.rb'修复'它,但不是一个好主意:

config.action_controller.permit_all_parameters = true

而是添加这个并不能解决问题,不确定原因:

config.action_controller.always_permitted_parameters =  [:current_page, :page, :total_pages, :per_page, :remote, :paginator]

之前的rake db:rollback停滞不前.现在,在尝试新迁移时,我们收到以下错误:

rake aborted!
ActiveRecord::ConcurrentMigrationError:

我们正在使用Postresql

我们正在尝试将DHH的简单Rails 5聊天示例部署到AWS上的单个自包含EC2实例.代码可在此处获取:https://github.com/HectorPerez/chat-in-rails5

我们使用Elastic Beanstalk来启动单个实例:

eb create dev-env -p “64bit Amazon Linux 2015.09 v2.0.4 running Ruby
2.2 (Puma)” –single -i t2.micro --envvars
SECRET_KEY_BASE=g5dh9cg614a37d4bdece9126b42d50d0ab8b2fc785daa1e0dac0383d6387f36b

这是一个最小的安装,因此没有Elasticache,也没有负载均衡器.要在EC2实例上安装redis,我们添加了一个.ebextensions配置文件,如下所示:https://gist.github.com/KeithP/08b38189372b7fd241e5#file-ebextensions-redis-config ; Git提交和部署.

但是websocket不起作用:检查浏览器控制台,我们看到这个错误一遍又一遍地重复:

application-a57354de3399cd895ca366df9bd7316ab69e81d266b63be7d7be563ebc78ab9d.js:27 
WebSocket connection to ‘ws://dev-env-y2e5dcrxqk.elasticbeanstalk.com/cable’ failed: 
Error during WebSocket handshake: Unexpected response code: 404

服务器production.log为每个"Finished/cable"呼叫显示2"Started GET/cable".ActiveCable没有DEBUG消息:

我正在尝试Rail 5.2.0.rc1 Active Storage,使用其包含的JavaScript库将PDF文档直接从客户端上传到云端.但在提交表单时,我在Firefox和Chrome中都出现了浏览器错误:

Cross-Origin Request Blocked... (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).

因此,在activestorage.js中设置标题为this.xhr.setRequestHeader ...并且似乎不可配置:https://github.com/rails/rails/blob/master/activestorage/app/javascript/activestorage/blob_record. JS

有人建议吗？
