I am looking for some clarification about what ActiveRecord is actually doing when it performs validation of an instance of a class that inherits from ActiveRecord::Base. For the purpose of discussion here is an example (you can assume that bar is a column in the foos table generated by an AR migration) class Foo < ActiveRecord::Base def bar read_attribute(:bar).length end end f = Foo.
我正在寻找一些有关ActiveRecord在执行从ActiveRecord :: Base继承的类的实例的验证时实际做了什么的澄清。 为了讨论的目的，这里是一个例子（你可以假设bar是由AR迁移生成的foos表中的一列） class Foo < ActiveRecord::Base def bar read_attribute(:bar).length end end f = Foo.new f.bar = 'abcdefg' f.bar => 7 f.read_attribute(:bar) => 'abcdefg' 我想了解的是当ActiveRecord调用.valid时？ （或调
I am currently using Vim for Python, and would like to start using it while I learn Ruby too. Is there a way to configure the vimrc file so that different settings apply depending on the filetype currently being worked on? For example, my vimrc is currently set to have an indentation of 4 spaces, which I would like to be 2 spaces for Ruby files. Additionally, I would like the syntax Ruby syn
我目前正在使用Vim for Python，并希望在我学习Ruby的时候开始使用它。 有没有办法配置vimrc文件，以便根据当前正在处理的文件类型应用不同的设置？ 例如，我的vimrc目前被设置为具有4个空格的缩进，我希望对于Ruby文件是2个空格。 此外，我希望Ruby语法突出显示的语法在处理ruby文件时使用，Python语法突出显示python文件。 我偶然发现了这个定义标签空间的方法： autocmd FileType python set tabstop=8|set shiftwidth
I'm finding it very difficult to survey the options for game programming in Ruby. Several wrappers and frameworks that are mentioned in other posts and articles are no longer maintained or in use. Gosu / Ruby seems to still be active: there's been a steady amount of chatter on the official forums. Any other actively maintained game frameworks for ruby ? EDIT: I discovered a healthy
我发现在Ruby中调查游戏编程的选项非常困难。 其他帖子和文章中提到的几个包装和框架不再维护或使用。 Gosu / Ruby似乎仍然活跃：官方论坛上一直存在稳定的交谈。 任何其他积极维护的红宝石游戏框架 ？ 编辑：我发现与MacRuby进行的游戏开发的健康数量。 我一直在使用一些这样的框架。 我从Gosu转到Rubygame。 Rubygame的代码库在过去的六个月里并没有经常更新， 但人们仍然摇摆不定。 至于我，Rubygame更方便。
Is it possible to use OAuth with HTTParty? I'm trying to do this API call, but, contradictory to the documentation, it needs authentication. Before you say "Use a Twitter-specific Gem", hear me out--I've tried. I've tried twitter, grackle, and countless others, but none support this specific API call. So, I've turned to HTTParty. So, how could I use OAuth with HTT
有没有可能与HTTParty使用OAuth？ 我正在尝试执行此API调用，但与文档相矛盾，它需要身份验证。 在你说“使用Twitter特有的宝石”之前，请听我说 - 我已经尝试过了。 我试过twitter，grackle和其他无数人，但没有人支持这个特定的API调用。 所以，我转向了HTTParty。 那么，我怎么能用HTTParty来使用OAuth呢？ 我不认为HTTParty支持OAuth（虽然我不是HTTParty的专家，但对我来说它太高级，速度太慢）。 我只需使用OAuth
I've got a JSON array that is stored as text in my database. When I output the array, I am still seeing the nr (see below). I've tried a lot of decode methods, but I cant get it to work. Does anyone know how I would properly decode this so that the nr appear as actual line breaks? Thanks! What Outputs: {n "status" : 200,n "requestId" : "6e2f55da-6a78-4f23-ad79-6be56d51702b",n "
我有一个JSON数组，作为文本存储在我的数据库中。 当我输出数组时，我仍然看到 n r（见下文）。 我已经尝试了很多解码方法，但我无法让它工作。 有谁知道我会如何正确解码这个，这样 n r显示为实际换行符？ 谢谢！ 什么产出： {n "status" : 200,n "requestId" : "6e2f55da-6a78-4f23-ad79-6be56d51702b",n "likelihood" : 0.89,n "photos" : [ {n "typeId" : "gravatar",n "typeName" : "Gravatar",n "ur
What is the best way to pretty print JSON in Ruby with smart line wrapping , the way the "json" output formatter in underscore-cli handles it? For instance, a regular JSON pretty printer would output: { "a": [ "b", "c" ], "d": { "e": "f" }, "g": [ "some longer string" ] } But I'm looking for a configurable pretty printer in Ruby that, like underscore-
用smart line wrapping在Ruby中漂亮打印JSON的最佳方法是什么，下划线cli中的“json”输出格式化程序处理它的方式是什么？ 例如，一个普通的JSON漂亮打印机会输出： { "a": [ "b", "c" ], "d": { "e": "f" }, "g": [ "some longer string" ] } 但是我在Ruby中寻找一个可配置的漂亮打印机，就像下划线cli一样，注意到小的结构会造成毫无意义的短线条，所以输出如下所示： { "a": [ "b", "c" ],
I'm sure I have a basic rescue_from question here but, I am trying to get a desired output when an exception is raised when my Validation fails but I can't seem to figure it out. Currently my ApplicationController is as follows: class ApplicationController < ActionController::API include ActionController::Serialization rescue_from ActiveRecord::RecordInvalid do |e| render jso
我确信我在这里有一个基本的rescue_from问题，但是，当我的Validation失败时引发异常，但我似乎无法弄清楚，我试图获得期望的输出。 目前我的ApplicationController如下所示： class ApplicationController < ActionController::API include ActionController::Serialization rescue_from ActiveRecord::RecordInvalid do |e| render json: {error: e.message}, status: 404 end end 我得到的JSON输出是：

I have a large hash with nested arrays and hashes. I would like to simply print it out so it 'readable' to the user. I would like it to be sort of like to_yaml - that's pretty readable - but still too tech looking. Ultimately its going to be end users who need to read these data chunks so they need to be formatted cleanly. Any suggestions? require 'pp' pp my_hash Use pp if yo
我有一个嵌套数组和散列的大散列。 我想简单地将其打印出来，以便用户可读。 我希望它有点像to_yaml - 这是非常可读的 - 但仍然太科技看。 最终它将成为需要阅读这些数据块的最终用户，因此他们需要格式化得干净利落。 有什么建议么？ require 'pp' pp my_hash 如果您需要内置解决方案并只需要合理的换行符，请使用pp 。 如果您可以安装宝石，请使用awesome_print。 （根据您的用户，您可能希望使用index:false选项
