Backslash Escaping in View

Rails
1

Ok, I’m hoping this won’t be a forehead slapper, but take a look at this
code:

physician.name.sub(/’/, “\’”)

I’m trying to substitute a single quote with a backslash and a single
quote. This seems pretty simple right? Well, someone kick me and
tell me why it’s not :slight_smile:

Here’s what I’m getting if the physician’s name is Test’s User:

Tests Users User

Huh? Is this normal Ruby behavior (meaning I shoulda sent this to the
Ruby group) or is it something funky with the View code? (which is why
I sent this here first)

Thanks,

you neeed to replace it with “\\'”

have a look here:

and in the documentation for sub

Ahhh, I should have thought to search for “backreference” instead of
just backslash. I did look at the API reference for the String object
but it didn’t mention the quadruple backslash.

Thanks for the info!
