Truncate string in Rails: "..." showing up on strings at length

Question

I'm currently trying to truncate any strings greater than 65 characters.

My code is

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

It works great for titles longer than 65 characters. But titles that are exactly 65 character still get truncated.

For example:

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

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

Should I not be using truncate?

Answer 1

truncate is the right method. This might be a bug in your version of rails? Here's what I get on my console:

[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..."

I'm running Rails 4.0.4 in this example.

If you are using rails 4.2 or above then you can use truncate_words method.

<title><%= (title.html_safe).truncate_words(5) %></title>
