How to get rid of characters from ruby array output?

Question

I have array output I am outputting to the Show page like this:

@store.products.map(&:title)

But the output to the page includes the [" "] that I don't want, like:

Product: ["Hair Pins"]

How can I get rid of the brackets and quotes? Why isn't it just returning the string without the characters?

I have tried strip, chomp, and those don't work. Is there a regular expression I can use to clip off the brackets and quotes?

Thank you!

please provide the code used to render the output and I'm sure we can fix this real quick. Where is "Product: " coming from? — Kyle

This looks like the output of p rather than the output of to_s — matt

If you want to print the products on a single line this should work:

@store.products.map(&:title).join(",")

So you have a String instead of an Array being rendered

Sweet! the .join(",") did the trick. Thank you. I had a feeling it was something simple.

You can get rid of the brackets and quotes by using:

["Hair Pins"].gsub('[', '').gsub(']', '').gsub('"', '')

Most likely, the brackets are being added unintentionally. The best solution is to identify where that's happening and not put them there in the first place.
