Hi everyone,
I'm sure I'm doing something stupid with this, so if somebody could talk some sense into me that would be great
I'm trying to just increment a variable and I think I'm missing some basic concept (this is RoR 2.0.2 btw)
So have a "players" table with several variables, including one called "odds". I'm using the basic scaffold generator for the CRUD stuff, but in my model I have:
attr_reader :odds
def initialize(odds) @odds = odds end
This results in: You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occurred while evaluating nil.+
I can view the correct odds number by using 'puts odds.to_s' but it won't let me set it at any point. Am I missing something?
Thanks in advance!
This is just a guess, but I would try replacing attr_reader with attr_accessor. It may be that since you're not telling ruby to make a method for setting odds, that it is unable to set it via the @odds variable.
I'm no expert, but I play one on tv.
cheers, jp
