Rails文章助手-"a"或“一个" [英] Rails article helper - "a" or "an"

问题描述

有人知道可以自动将适当的文章添加到给定字符串的Rails Helper吗?例如，如果我将苹果"传递给函数，它将变成一个苹果"，而如果我发送香蕉"，它将返回香蕉"

Does anyone know of a Rails Helper which can automatically prepend the appropriate article to a given string? For instance, if I pass in "apple" to the function it would turn out "an apple", whereas if I were to send in "banana" it would return "a banana"

我已经检查了Rails TextHelper模块，但找不到任何内容.抱歉，如果这是重复项，但是对于搜索...来说，这无疑是一个艰难的答案.

I already checked the Rails TextHelper module but could not find anything. Apologies if this is a duplicate but it is admittedly a hard answer to search for...

推荐答案

我不知道，但是为这个权利写一个助手似乎很简单? 不在我的头上

None that I know of but it seems simple enough to write a helper for this right? Off the top of my head

def indefinite_articlerize(params_word)
    %w(a e i o u).include?(params_word[0].downcase) ? "an #{params_word}" : "a #{params_word}"
end
