Rails 5.0.0.beta4在包含dynamic:action和:controller segments的路由上引入了弃用警告:

DEPRECATION WARNING: Using a dynamic :action segment in a route is deprecated and will be removed in Rails 5.1. 

来自此PR的提交消息指出:

允许:controller和:通过config/routes.rb中的路径指定的操作值一直是Rails中导致安全性发布的许多问题的根本原因.鉴于此,最好将控制器和操作明确列入白名单,而不是试图将"坏"值列入黑名单或消毒.

你会如何将一组动作参数"列入白名单"？我的路由文件中有以下内容,它们提出了弃用警告:

namespace :integrations do
  get 'stripe(/:action)', controller: 'stripe', as: "stripe"
  post 'stripe/deactivate', controller: 'stripe', action: 'deactivate'
end

我有rails 5 rc1的这个问题.有没有人知道如何在环境文件中配置它以及rails 5活动记录的默认连接池大小是什么.

我将项目升级到Rails 5.当我运行时,rspec我收到警告

DEPRECATION WARNING: alias_method_chain is deprecated. Please, use Module#prepend instead. 
From module, you can access the original method using super. 
(called from <top (required)> at /home/alex/projects/myproject/config/application.rb:13)

application.rb中的失败行是:

Bundler.require(*Rails.groups)

如何找出导致此弃用警告的原因以及如何消除错误？

在rails 5应用程序内的终端中使用命令

rails c

抛出的错误如下所示.我不知道这在类似的问题中意味着什么,解决方案是使用弹簧停止.我也试过了,但没有它仍然给出同样的错误.如果有人能指出这里的错误,那将会很棒.

Rails 5提供参数过滤,我已经指定config.filter_parameters += ["my_token"]了application.rb.

在dev(环境)模式下测试我的应用程序,我看到my_token从日志文件的请求行中正确过滤:

Started GET "/something?my_token=[FILTERED]"

但是,紧跟在后面的SQL日志行仍然以纯文本形式包含参数的值("SELECT stuff FROM things"等,my_token作为参数).

Rails 5是否提供了从日志文件的SQL部分过滤此原始值的方法？

我还在生产模式下运行我的应用程序,虽然日志文件更简洁,但它们仍然在生成的SQL语句的D类型日志行中显示未过滤的值.

我没有指定自定义日志设置 - 默认情况下,我的过滤器参数设置以外的所有设置.

我自己的搜索显示没有相关的讨论.也许我错过了什么？

谢谢!

我正在使用Rails 5.我想使用下面的代码解析.xls(不要与.xlsx doc混淆)

  book = Roo::Spreadsheet.open(file_location)
  sheet = book.sheet(0)
  text = sheet.to_csv
  csv = CSV.parse(text)

  arr_of_arrs = csv
  text_content = ""
  arr_of_arrs.each do |arr|
    arr.map!{|v| v && v.to_f < 1 && v.to_f > 0 ? TimeFormattingHelper.time_as_str(v.to_f * 24 * 3600 * 1000) : v}
    text_content = "#{text_content}\n#{arr.join("\t")}"
  end

这是我在上面引用的方法

  def time_as_str(time_in_ms)
    regex = /^(0*:?)*0*/
    Time.at(time_in_ms.to_f/1000).utc.strftime("%H:%M:%S.%1N").sub!(regex, '')
  end

我遇到麻烦的一个方面是我的.xls doc中出现的单元格

24:08:00

被处理为

1904-01-02T00:08:00+00:00

使用上面的代码.如何解析我在屏幕上看到的值？也就是说,如何将日期值转换为时间值？

作为另一个Excel文档的示例,显示为的单元格

24:02:00

正在被上面的代码解析为

1899-12-31T00:02:00+00:00

我们正在使用Postresql

我正在开发一个项目,我们不会使用ajax调用来提交表单,所以我需要local: true在项目中输入每个表单,如rails docs中所示:

:local - By default form submits are remote and unobstrusive XHRs. Disable remote submits with local: true.

有没有办法默认将local选项设置为true？

我们正在使用这样的Rails 5 form_with助手:

<%= form_with(model: @user, local: true) do |f| %>
    <div>
        <%= f.label :name %>
        <%= f.text_field :name %>
    </div>

    <div>
        <%= f.label :email %>
        <%= f.email_field :email %>
    </div>
    <%= f.submit %>
<% end %>

我正在将Jelastic用于我的开发环境(尚未投入生产).我的应用程序与Unicorn一起运行,但我发现带有ActionCable的websockets并将其集成到我的应用程序中.

一切都在本地工作正常,但在部署到我的Jelastic环境(使用默认的NGINX/Unicorn配置)时,我在我的javascript控制台中收到此消息,我在访问日志中看不到任何内容

WebSocket connection to 'ws://dev.myapp.com:8080/' failed: WebSocket is closed before the connection is established.

我曾经在我的本地环境中通过在配置文件中添加所需的ActionCable.server.config.allowed_request_origins来解决它.所以我仔细检查了我的开发配置,这没关系.

这就是为什么我想知道NGINX配置是否有特定的东西,除了在ActionCable git页面上解释的内容

bundle exec puma -p 28080 cable/config.ru

对于我的应用程序,我在这里输入链接描述,但没有提及任何有关NGINX配置的内容

我知道带有ActionCable的websocket很新,但我希望有人能够在这方面给我一个带头

非常感谢

我正在尝试创建一个暴露ActionCable频道的gem,但我无法让它工作.

这是我的宝石

# lib/my_channel.rb
class MyChannel < ActionCable::Channel::Base
  def wait(data)
    # logic ...
  end
end

# lib/engine.rb
module MyApp
  class Engine < ::Rails::Engine
    isolate_namespace MyApp
  end
end

然后我将gem添加到我的主应用程序中Gemfile,运行bundle install,启动控制台并运行MyChannel.哪个不产生和错误,意味着通道被正确包含.

然后我将其添加到我的主应用程序中

// application.js
var socket = "ws://localhost:3000/cable";
var cable = ActionCable.createConsumer(socket);
cable.subscriptions.create({ "channel": "MyChannel" }, {
  received: function(){
    // ...
  }
});

但是我收到了这个错误

Subscription class not found ({"command"=>"subscribe", "identifier"=>"{\"channel\":\"MyChannel\"}"})

我错过了什么？
