Want to show the first 50 or 60 words of a text field in ruby?

Question

I have a stories text field and want to show the first few lines – say the first 50 words of that field – in a snapshot page. How can I do that in Ruby (on Rails)?

Answer 1

Assuming your words are delimited by a space, you can do something like this.

stories.split(' ').slice(0,50).join(' ')
