Rails 5 GET request nested array parameter changes unexpectedly

问题 I have upgraded a Rails 4 application to Rails 5 (5.2.4.1 to be exact). I have a GET endpoint in my code with an rspec test. The test code sends the request as: get :fetch, params: { id: 123, logs: [[1, 2, :weekly], [1, 4, :mothly]] } When the controller receives the request, params['logs'] contains [["1"], ["2"], ["weekly"], ["1"], ["4"], ["monthly"]] This is different from what I expected, which is [["1", "2", "weekly"], ["1", "4", "monthly"]] The incoming URL contains (after decoding the

Adding 'SameSite=None;' cookies to Rails via Rack middleware?

由 别等时光非礼了梦想. 提交于 2020-04-13 03:59:49
问题 On February 4th 2020, Google Chrome will require SameSite=None; to be added to all cross-site cookies. Rails 6.1 and soon Rails 6.0 have added a same_site: :none option to the rails cookie hash: cookies["foo"]= { value: "bar", expires: 1.year.from_now, same_site: :none } But older Rails 5.x apps won't receive the upgrade to have access to the same_site options hash. I know the SameSite=None; cookie option can be manually added to Rails in a controller using: response.headers["Set-Cookie"] =

How to set port for Rack app?

由 邮差的信 提交于 2020-04-10 03:27:05
问题 builder.rb: def app Rack::Builder.new do run App.new end.to_app end How to run on a given port? 回答1: Try: Rack::Handler.default.run(app, :Port => 3000) Although it would be more typical to run your app in a config.ru file and specify port as a command line option to rackup , e.g.: rackup -p 3000 . 回答2: When you rackup just specify it with option -p so: rackup -p 8808 would work just fine. 来源： https://stackoverflow.com/questions/32594945/how-to-set-port-for-rack-app

分布式存储原理：ElasticSearch

3 月，跳不动了？>>> 对于一个分布式存储系统来说， 数据是分散存储在多个节点上的 。如何让数据 均衡 的分布在不同节点上，来保证其高可用性？ 所谓均衡，是指系统中每个节点的负载是均匀的，并且在发现有不均匀的情况或者有节点增加/删除时，能及时进行调整，保持均匀状态 。本文将探讨Elasticsearch的数据分布方法，文中所述的背景是Elasticsearch 5.5。   在Elasticsearch中，以Shard为最小的数据分配/迁移单位。数据到节点的映射分离为两层：一层是数据到Shard的映射（Route），另一层是Shard到节点的映射（Allocate）。   一方面，插入一条数据时， ES会根据指定的Key来计算应该落到哪个Shard上 。默认Key是自动分配的id，可以自定义，比如在我们的业务中采用CompanyID作为Key。 因为Primary Shard的个数是不允许改变的，所以同一个Key每次算出来的Shard是一样的，从而保证了准确定位 。 shard_num = hash(_routing) % num_primary_shards   另一方面，Master会为每个Shard分配相应的Data节点进行存储，并维护相关元信息。 1、通过Route计算出来的Shard序号，2、在元信息中找到对应的存储节点，便可完成数据分布 。Shard

调试 ambari-server 总结

刚开始debug ambari-server的时候，很多逻辑都是第一次接触。其中有很多知识点还是记录一下的好，做个备忘。这些知识点对于自定义api的开发还是很有作用的。 1. api的子href的最后一个字符串如何定义？例如，指定一个id？ 解答： ambari 2.6 编辑key_properties.json，将当前资源类型与含有id的value相映射。 举例： <!--more--> ambari 2.7 路径：org/apache/ambari/server/controller/internal/RackResourceProvider.java public static final String RACK_ID_PROPERTY_ID = PropertyHelper.getPropertyId("rack", "rack_id"); public static final String RACK_NAME_PROPERTY_ID = PropertyHelper.getPropertyId("rack", "rack_name"); public static final String RACK_HEIGHT_PROPERTY_ID = PropertyHelper.getPropertyId("rack", "rack_height"); public

For a rack app, how do I make passenger-standalone serve the output of .erb files rather of sending the .erb file itself?

由 霸气de小男生 提交于 2020-01-17 09:28:32
问题 I have a simple config.ru rack app where I only require and run rack-server-pages to provide dynamic pages in a quick and convenient way. This config.ru app is served by phusion passenger-standalone (which uses nginx internally). .erb files are processed and served correctly, except when I explicitely add the .erb extension to a URL (for a .erb file). In that case the server will send me the .erb file for download, rather than its output. Obviously I would like to avoid that. To make it
