在 Rails 中生成 slugs(人类可读的 ID)的最佳方法 [英] Best way to generate slugs (human-readable IDs) in Rails

问题描述

你知道，比如 myblog.com/posts/donald-e-knuth.

我应该使用内置的<代码>参数化方法?

插件呢?我可以想象一个插件可以很好地处理重复的 slug 等.这里有一些流行的 Github 插件——有没有人有使用它们的经验?

1. http://github.com/rsl/stringex/tree/master
2. http://github.com/norman/friendly_id/tree/master

基本上，slug 似乎是一个完全解决的问题，我不会重新发明轮子.

解决方案

我使用了以下内容

• 翻译&--> "and" 和 @ --> "at"
• 不插入下划线代替撇号，所以 "foo's" --> "foos"
• 不包括双下划线
• 不会创建以下划线开头或结尾的 slug

<预><代码>def to_slug#剥离字符串ret = self.strip#吹掉撇号回复！/['`]/,""# @ --> at, and & --> andret.gsub！/\s*@\s*/, " 在 "回复！/\s*&\s*/, " 和 "#用下划线替换所有非字母数字、下划线或句点回复！/\s*[^A-Za-z0-9\.\-]\s*/, '_'#将双下划线转换为单下划线回复！/_+/,"_"#去掉前导/尾随下划线回复！/\A[_\.]+|[_\.]+\z/,""回复结尾

例如:

<预><代码>>> s = "爸爸妈妈@home！"=>爸爸妈妈@home！">> s.to_slug> 妈妈和爸爸在家里"

You know, like myblog.com/posts/donald-e-knuth.

Should I do this with the built in parameterize method?

What about a plugin? I could imagine a plugin being nice for handling duplicate slugs, etc. Here are some popular Github plugins -- does anyone have any experience with them?

1. http://github.com/rsl/stringex/tree/master
2. http://github.com/norman/friendly_id/tree/master

Basically it seems like slugs are a totally solved problem, and I don't to reinvent the wheel.

解决方案

I use the following, which will

• translate & --> "and" and @ --> "at"
• doesn't insert an underscore in place of an apostrophe, so "foo's" --> "foos"
• doesn't include double-underscores
• doesn't create slug that begins or ends with an underscore

  def to_slug
    #strip the string
    ret = self.strip

    #blow away apostrophes
    ret.gsub! /['`]/,""

    # @ --> at, and & --> and
    ret.gsub! /\s*@\s*/, " at "
    ret.gsub! /\s*&\s*/, " and "

    #replace all non alphanumeric, underscore or periods with underscore
     ret.gsub! /\s*[^A-Za-z0-9\.\-]\s*/, '_'  

     #convert double underscores to single
     ret.gsub! /_+/,"_"

     #strip off leading/trailing underscore
     ret.gsub! /\A[_\.]+|[_\.]+\z/,""

     ret
  end

so, for example:

>> s = "mom & dad @home!"
=> "mom & dad @home!"
>> s.to_slug
> "mom_and_dad_at_home"
