html - 在 Rails : "..." showing up on strings at length 中截断字符串

Question

我目前正在尝试截断任何超过 65 个字符的字符串。

我的代码是

<title><%= truncate(title.html_safe, length:65) %></title>

它非常适合长度超过 65 个字符的标题。但是恰好 65 个字符的标题仍会被截断。

例如:

title:"This post is exactly 65 characters characters characters characte"

shows on page as "This post is exactly 65 characters characters characters chara..."

我不应该使用 truncate 吗？

Answer 1

truncate 是正确的方法。这可能是您的 rails 版本中的错误？这是我在控制台上得到的:

[5] pry(main)> helper.truncate("This post is exactly 56 characters characters characters characte", length: 65)
=> "This post is exactly 56 characters characters characters characte"
[6] pry(main)> helper.truncate("This post is exactly 56 characters characters characters characte", length: 64)
=> "This post is exactly 56 characters characters characters char..."

在此示例中，我运行的是 Rails 4.0.4。
