I like how Rails gives me flexibility in naming view files, ie index.erb or index.html.erb essentially do the same thing. The problem is that I've merged two separate projects, where one uses filename.erb for all its views and the other uses filename.html.erb. It seems that Rails expects only one naming scheme as I keep getting missing...

I am writing an IRC bot and my intention is to have "!reboot" reboot the bot. I have already got it to part from a channel and break the running loop, but I cannot get it to re-run the file.

I am experimenting with Ruby and Rails. I like Ruby, but not Rails. I have Java/PHP background, I have used some frameworks, but never totally liked any of them.

I'm sure this is a very simple question, but I'm just a newbie so... I have a model, Game, which has_many :piles. Pile, in turn, has_many :cards. I'm able to populate the Piles and Cards at creation of the Game, so my code at present looks something like: class Game < ActiveRecord::Base has_many :piles def after_create 1.upto(...
Hello, I'm very new to ruby and I'm trying to write a web application using the rails framework. Through reading I've seen methods being called like this: some_method "first argument", :other_arg => "value1", :other_arg2 => "value2" Where you can pass an unlimited number of arguments. How do you create a method in ruby that can be u...

I wrote this code to achieve it (assuming that the array is not empty, which is not the case in my situation) if array.length == 1 result = array[0] else result = "#{array[0, array.length].join(', ')} a...

I have a 2-dimensional array in Ruby that I want to produce a working duplicate of. Obviously I can't do this; array=[[3,4],[5,9],[10,2],[11,3]] temp_array=array as any modifications I make to temp_array will also be made to array, as I have merely copied the object identifier. I thought I would be able to get around this by simply us...
I've got a project for work I'd like to do in Ruby that will have to run on Windows, but perturbing the filesystem for a Ruby install or RubyScript2Exe unpack isn't an option (this is supposed to be the harness for a testing system). Has anyone successfully used Crate to package up something on Windows? If so, what was your build envi...
I've come across conversions of the form Array(value), String(value), and Integer(value) on occasion. It appears to me that these are just syntactic sugar for a call to the corresponding value.to_a, value.to_s, or value.to_i methods. So I'm wondering: Where/how are these are defined? I can't find them in Object, Module, Class, etc A...
