Question

So having trouble figuring this one out mainly because I don’t know the correct terminology. I want to print certain characters out of a string based on their place in the string.

Example. Let’s say I have a string 2012-08-18 being printed from RoR. Now, what I want to do is actually just print out the last two characters, in this case, 18. I always want to print the last two characters, as they will always be the day.

Thoughts?

Here’s my current code where I need to add this:

<%= event.start_date %>

which prints out

2012-08-18

Thanks.

If you only want the day numbers, you should use the method “strftime”

See here the documentation here on Rubyonrails.org

In your case, you can use this :

<%= event.start_date.strftime("%d") %> # Will print the day of the month (01..31)

Hope this helps!
