Question

How can I join two strings (both are numbers) together without having them added together? For example:

@output = 2567 + 18

What I Don’t Want:

The result returns "2585" (it has added the two numbers together mathematically).

What I Do Want:

The result returns "256718". As you can see, this time the two numbers have been joined together, not added.

A Real Example:

Profile.create(:permalink => 2585 && User.last.id)

When I run that line from my model – the row titled "permalink" simply gets the last created user ID, and "2585" isn’t joined in front of it. Also, if I used the "+" method instead of "&&" like in the first example, the two numbers are added together mathematically.

Any ideas?

Answer 1

Convert both values to strings. The first with a string literal and the second with an explicit conversion using the to_s method.

Profile.create(:permalink => "2585" + User.last.id.to_s)
