最佳答案
li 只有 display: list-item
list-style 相关样式

我有一个模型:classItem项目有一个属性“商店”基于存储的值，我希望Item对象对特定方法具有不同的行为。Rails中是否有针对此的通用设计模式？如果方法中没有大的if-else语句，这是如何干净利落地完成的？ 最佳答案 通常通过Single-TableInheritance. 关于ruby-on-rails-Rails-子类化模型的设计模式是什么？，我们在StackOverflow上找到一个类似的问题： https://stackoverflow.co
我想将html转换为纯文本。不过，我不想只删除标签，我想智能地保留尽可能多的格式。为插入换行符标签，检测段落并格式化它们等。输入非常简单，通常是格式良好的html(不是整个文档，只是一堆内容，通常没有anchor或图像)。我可以将几个正则表达式放在一起，让我达到80%，但我认为可能有一些现有的解决方案更智能。 最佳答案 首先，不要尝试为此使用正则表达式。很有可能你会想出一个脆弱/脆弱的解决方案，它会随着HTML的变化而崩溃，或者很难管理和维护。您可以使用Nokogiri快速解析HTML并提取文本:require'nokogiri'h

我正在使用的第三方API的文档状态:"[O]urAPIonlyacceptspaddedBase64encodedstrings."什么是“填充的Base64编码字符串”以及如何在Ruby中生成它们。下面的代码是我第一次尝试创建转换为Base64的JSON格式数据。xa=Base64.encode64(a.to_json) 最佳答案 他们说的padding其实就是Base64本身的一部分。它是末尾的“=”和“==”。Base64将3个字节的数据包编码为4个编码字符。所以如果你的输入数据有长度n和n%3=1=>"=="末尾用于填充n%
我主要使用Ruby来执行此操作，但到目前为止我的攻击计划如下:使用gemsrdf、rdf-rdfa和rdf-microdata或mida来解析给定任何URI的数据。我认为最好映射到像schema.org这样的统一模式，例如使用这个yaml文件，它试图描述数据词汇表和opengraph到schema.org之间的转换:#SchemaXtoschema.orgconversion#data-vocabularyDV:name:namestreet-address:streetAddressregion:addressRegionlocality:addressLocalityphoto:i
我好像记得Lua有类似Ruby的method_missing的东西。还是我记错了？ 最佳答案 表的metatable的__index和__newindex可以用于与Ruby的method_missing相同的效果。 关于ruby-难道Lua没有和Ruby的method_missing相媲美的东西吗？，我们在StackOverflow上找到一个类似的问题： https://stackoverflow.com/questions/7732154/
为什么4.1%2返回0.0999999999999996？但是4.2%2==0.2。 最佳答案 参见此处:WhatEveryProgrammerShouldKnowAboutFloating-PointArithmetic实数是无限的。计算机使用的位数有限(今天是32位、64位)。因此计算机进行的浮点运算不能代表所有的实数。0.1是这些数字之一。请注意，这不是与Ruby相关的问题，而是与所有编程语言相关的问题，因为它来自计算机表示实数的方式。 关于ruby-为什么4.1%2使用Ruby返
我有一个对象has_many应呈现为xml的子对象。这不是问题。我的问题是我创建了一个Hash包含此数据，就像解析器需要它一样。但是rails自动将整个文件包含在.........我需要摆脱type="array"和我该如何处理？我没有在文档中找到任何内容。 最佳答案 我遇到了同样的问题；这是我的XML:我在用这个:entries.to_xml将散列数据转换为XML，但这会将条目的数据包装到中所以我修改了:entries.to_xml(root:"Contacts")但这仍然将转换后的XML包装在“联系人”中，将我的XML代码修改为
