嵌套命名空间资源 form_with 如何使用？

Kastrcn-github — Wed, 15 May 2024 10:32:36 +0800

嵌套命名空间资源

scope 'admin' do
   namespace :app_version do
     resources :applications do
       resources :channels 
       end
     end
   end
 end

form_with 会生成错误的前缀

如果是 applications 生成的是 app_version_applications_path 没有问题

如果是 channels 会生成 app_version_applications_app_version_channels_path 每一个资源都会加这个前缀正确的是貌似是 app_version_applications_channels_path

现在我用 if 判断自己写的

<%= form_with(model: [channel], url: channel.new_record? ? app_version_application_channels_path : app_version_application_channel_path(channel.application, channel), scope: :channel, local: true) do |form| %>

类似问题 https://gorails.com/forum/using-form_with-produces-odd-results-for-nested-namespaced-resources

请问这个爬虫规则是给什么框架用的？

"class.xing_vb5.0@text"

"class.xing_vb6.0@text|class.xing_vb7.0@text"

"class.vodImg.0@tag.img@src"

第一句话意思好像找到类为 xing_vb5 的第一个元素的内容

Rails Nginx 代理 https wss http 访问 ws 、https 如何访问 wss

Kastrcn-github — Wed, 05 Dec 2018 01:10:11 +0800

通过 niginx 把 http 代理成 https 把 ws 代理成 wss

配置如下

访问 http 页面页面调用 ActionCable.createConsumer(); 调用 ws 没有问题

访问 https 页面页面调用 ActionCable.createConsumer(); 调用 ws 报错 https 不能访问 ws

求解如何将 http 页面访问 ws，https 访问 wss

cable.js

(function() {
  this.App || (this.App = {});

  App.cable = ActionCable.createConsumer();

}).call(this);

production.rb

config.action_cable.url = 'ws://XXX.com/cable'

nginx

   listen 80;
   server_name XXX.com;

   index index.html index.htm;
   location / {
       root html;

   proxy_set_header Connection "Upgrade";
  }
