But using form_remote_tag I end up with nothing inside my update div. I tested with rendering text so the right method is being executed and YM4R/GM is returning the Google Maps KML. But t...

I'm just starting with "The Well-Grounded Rubyist", and they gave the following example: print "Hello. Please enter a Celsius value: " print "The Fahrenheit equivalent is ", gets.to_i * 9 / 5 + 32, ".\n" In particular, I'm looking at line 2, where they seem to be using commas for string concatenation. I assume the + symbol isn't being...

I don't know ruby very well, but I'm trying to add some functionality to this script a co-worker wrote. Basically right now it takes a few flags and standard in as input, and it uses OptionParser to parse the flags.

Today I ran into an issue using RoR to stub calls to AR objects. I thought that I'd be able to do something along the lines of : stub.instance_of(BankAccount).save_to_other_spot { true } However when I tried this method it didn't seem to stub the method at all and it would end up running the original method I was trying to stub. I con...
