• how to organize classes in ruby if they are literal subclasses

  - by RetroNoodle

  I know that title didn't make sense, Im sorry! Its hard to word what I am trying to ask. I had trouble googling it for the same reason. So this isn't even Ruby specific, but I am working in ruby and I am new to it, so bear with me. So you have a class that is a document. Inside each document, you have sentences, and each sentence has words. Words will have properties, like "noun" or a count of how many times they are used in the document, etc. I would like each of the elements, document, sentence, word be an object. Now, if you think literally - sentences are in documents, and words are in sentences. Should this be organized literally like this as well? Like inside the document class you will define and instantiate the sentence objects, and inside the sentence class you will define and instantiate the words? Or, should everything be separate and reference each other? Like the word class would sit outside the sentence class but the sentence class would be able to instantiate and work with words? This is a basic OOP question I guess, and I suppose you could argue to do it either way. What do you guys think? Each sentence in the document could be stored in a hash of sentence objects inside the document object, and each word in the sentence could be stored in a hash of word objects inside the sentence. I dont want to code myself into a corner here, thats why I am asking, plus I have wondered this before in other situations. Thank you!

• Explaining a Ruby code snippet

  - by Michael Foukarakis

  I'm in that uncomfortable position again, where somebody has left me with a code snippet in a language I don't know and I have to maintain it. While I haven't introduced Ruby to myself some parts of it are quite simple, but I'd like to hear your explanations nonetheless. Here goes: words = File.open("lengths.txt") {|f| f.read }.split # read all lines of a file in 'words'? values = Array.new(0) words.each { |value| values << value.to_i } # looked this one up, it's supposed to convert to an array of integers, right? values.sort! values.uniq! diffs = Array.new(0) # this looks unused, unless I'm missing something obvious sum = 0 s = 0 # another unused variable # this looks like it's computing the sum of differences between successive # elements, but that sum also remains unused, or does it? values.each_index { |index| if index.to_i < values.length-1 then sum += values.at(index.to_i + 1) - values.at(index.to_i) end } # could you also explain the syntax here? puts "delta has the value of\n" # this will eventually print the minimum of the original values divided by 2 puts values.at(0) / 2 The above script was supposed to figure out the average of the differences between every two successive elements (integers, essentially) in a list. Am I right in saying this is nowhere near what it actually does, or am I missing something fundamental, which is likely considering I have no Ruby knowledge?

• Calculations on the iteration count in for loop in Ruby 1.8.7

  - by user1805035

  I was playing around with Ruby and Latex to create a color coding set. I'm more than a novice with C++, but haven't looked at Ruby until now. So, still learning a lot of coding. I have the following block of code below. When attempting to run this, band1 = 1e+02. I've tried band1 = (BigDecimal(i) * 100).to_f thinking maybe there was some odd floating point issue. This is just me trying anything though as an integer multiplied by an integer should create an integer, if I'm still thinking correctly. I've tried a variety of other things as well (things that I can do in C++, but this ain't C++), but to no avail. (1..9).each do |i| #Band 1 (0..9).each do |j| #Band 2 (0..11).each do |k| #Band 3 #Band 3 Start #these are the colors of the resistor bands b1 = $c_band12[i] b2 = $c_band12[j] b3 = $c_band3[k] b4 = "Gold" oms = ((i*100) + (j*10)) * $mult[k] band1 = i*100 band2 = j band3 = $mult[k] end end end Not sure what I'm missing. Should I be using .each_with_index through these iterations? I've tried this: (1..9).each_with_index {|i, indexi| #Band 1 (0..9).each_with_index {|j, indexj| #Band 2 (0..11).each_with_index {|k, indexk| #Band 3 #Band 3 Start #these are the colors of the resistor bands b1 = $c_band12[i] b2 = $c_band12[j] b3 = $c_band3[k] b4 = "Gold" oms = ((i*100) + (j*10)) * $mult[k] band1 = indexk * 100 and I get the same answer. I can't see why 1*100 should equate to such a large number? Thank you, AT

• WEBrick::HTTPStatus::LengthRequired error when accessing create method in controller

  - by Chris Bisignani

  I have a very simple controller set up: class LibrariesController < ApplicationController ... def create @user.libraries << Library.new(params) @user.save render :json => "success!" end ... end Basically, whenever I try to access the create method of LibrariesController using HTTParty.post I get a WEBrick::HTTPStatus::LengthRequired error on the server.

  I'm trying to connect, read and write from a UNIX socket in Ruby. It is a stats socket used by haproxy.

• Book Review: Oracle ADF 11gR2 Development Beginner's Guide

  - by Grant Ronald

  Packt Publishing asked me to review Oracle ADF 11gR2 Development Beginner's Guide by Vinod Krishnan, so on a couple of long flights I managed to get through the book in a couple of sittings. One point to make clear before I go into the review.  Having authored "The Quick Start Guide to Fusion Development: JDeveloper and Oracle ADF", I've written a book which covers the same topic/beginner level.  I also think that its worth stating up front that I applaud anyone who has gone  through the effort of writing a technical book. So well done Vinod.  But on to the review: The book itself is a good break down of topic areas.  Vinod starts with a quick tour around the IDE, which is an important step given all the work you do will be through the IDE.  The book then goes through the general path that I tend to always teach: a quick overview demo, ADF BC, validation, binding, UI, task flows and then the various "add on" topics like security, MDS and advanced topics.  So it covers the right topics in, IMO, the right order.  I also think the writing style flows nicely as well - Its a relatively easy book to read, it doesn't get too formal and the "Have a go hero" hands on sections will be useful for many. That said, I did pick out a number of styles/themes to the writing that I found went against the idea of a beginners guide.  For example, in writing my book, I tried to carefully avoid talking about topics not yet covered or not yet relevant at that point in someone's learning.  So, if I was a new ADF developer reading this book, did I really need to know about ADFBindingFilter and DataBindings.cpx file on page 58 - I've only just learned how to do a drag and drop simple application so showing me XML configuration files relevant to JSF/ADF lifecycle is probably going to scare me off! I found this in a couple of places, for example, the security chapter starts on page 219 but by page 222 (and most of the preceding pages are hands-on steps) we're diving into the web.xml, weblogic.xml, adf-config.xml, jsp-config.xml and jazn-data.xml.  Don't get me wrong, I'm not saying you shouldn't know this, but I feel you have to get people on a strong grounding of the concepts before showing them implementation files.  If having just learned what ADF Security is will "The initialization parameter remove.anonymous.role is set to false for the JpsFilter filter as this filter is the first filter defined in the file" really going to help me? The other theme I found which I felt didn't work was that a couple of the chapters descended into a reference guide.  For example page 159 onwards basically lists UI components and their properties.  And page 87 onwards list the attributes of ADF BC in pretty much the same way as the on line help or developer guide, and I've a personal aversion to any sort of help that says pretty much what the attribute name is e.g. "Precision Rule: this option is used to set a strict precision rule", or "Property Set: this is the property set that has to be applied to the attribute". Hmmm, I think I could have worked that out myself, what I would want to know in a beginners guide are what are these for, what might I use them for...and if I don't need to use them to create an emp/dept example them maybe it’s better to leave them out. All that said, would the book help me - yes it would.  It’s obvious that Vinod knows ADF and his style is relatively easy going and the book covers all that it has to, but I think the book could have done a better job in the educational side of guiding beginners.

• Is there or why not having a ruby technology specification similar to Java's JSR?

  - by romeu.hcf

  I think on a community portal where specifications are made, documented and specified to reference libraries and systems implementation. An example: A specification for Message Queue where redis clients, for instance, could implement it and where the libraries could be validated by the specification's test suite. Redic, redis-rb, hiredis, redis-connection-pool, redis-namespace should all implement this specification. This way, being easily replaced.

• Ruby - when to use instance variables vs parameters between methods?

  - by Michael Durrant

  I'm writing several methods that call other methods. To pass the information I have a couple of choices: Pass the information as parameters Set instance variables so that other methods can access them When should I choose one option over the other? It seems that the first option is good as it is very specific about what is being passed. the downside seems to be that a lot of values are being passed around. The second method doesn't require passing all the values around but seems to lead to a lot of magic where methods set instance variables 'somewhere' Should I always be very explicit about gets passed to other methods in the class? Are there exceptions so this?

• Is Ruby on Rails' Active Record an example of Aspect-Oriented Programming?

  - by B Seven

  From Clean Code, about Cross-Cutting Concerns: Note that concerns like persistence tend to cut across the natural object boundaries of a domain. You want to persist all your objects using generally the same strategy, for example, using a particular DBMS... Is Active Record an example of aspect-oriented programming? In AOP, modular constructs called aspects specify which points in the system should have their behavior modified in some consistent way to support a particular concern. This specification is done using a succinct declarative or programmatic mechanism. If Active Record is an example of AOP, what is the "aspect"? Is it the class declaration that inherits from Active Record? class Foo < ActiveRecord::Base

• I'm confused with block in ruby, compared to smalltalk.

  - by weakish

  What does block in ruby mean? It looks similar with smalltalk, but you can't send messages to it. For example, in smalltalk: [:x | x + 3] value: 3 returns 6. But in ruby: {|x| x + 3}.call 3 will cause SyntaxError. Well, you can pass messages to lambda in ruby, though: irb(main):025:0> ->(x){x+3}.call 3 => 6 So in ruby, block is not a block, but lambda is a block? Is this true? I mean, are there any differences between ruby lambda and smalltalk block? If this is true, then what is ruby block?

• Is Ruby on Rails supposed to have a steep learning curve or is it just me?

  - by Anita

  I'm a self-taught programmer. I've been learning RoR since October with varying intensity (sometimes all day, sometimes nothing for several weeks). Before that I knew only Java, but knew it pretty well. I've heard so much hype about RoR and how it's supposed to make you happy, productive, etc. So far it's only made me frustrated. I learned it out of the Agile book, and I suspect part of the difficulty might have to do with my not knowing JavaScript and CSS, and having only a shaky grasp of databases and HTML. But apparently it took me much longer to complete the project in the Agile book than other people, and I still don't remember much of it. There are some things about Rails that I just can't seem to get, e.g. when to use symbols and when NOT to, or how dynamic methods are called. Recently I was given a small Rails assignment where I'm asked to make a small change to the interface. It's taken me around 25 hours and although I've made some progress in understanding the code, I still have no idea how to proceed. I can't even ask Stack Overflow because there is so much code I'll have to provide to give context. So my question is in the title: is RoR supposed to take a long time to learn or am I just slow? Can it be that I've been learning from the wrong book? My learning style is such that I either understand nothing or understand everything, if that makes sense. Thanks!

  I would like to ask you for advice more experienced ROR developers. I am new in programming and like to idea of ROR and I am before the decision on which programing language to specialize Java vs ROR. In the future I wish to learn for bigger international IT companies (IBM, Accenture etc.) but as I am reading their job openings, most of them are hiring Java, C++, .NET... Is the ROR used only in startups or also in bigger companies as well? What should be the reasons of their preference of Java over ROR?

• Escaping '“' with regular double quotes using Ruby regex

  - by DavidP6

  I have text that has these fancy double quotes: '“' and I would like to replace them with regular double quotes using Ruby gsub and regex. Here's an example and what I have so far: sentence = 'This is a quote, “Hey guys!”' I couldn't figure out how to escape double quotes so I tried using 34.chr: sentence.gsub("“",34.chr). This gets me close but leaves a back slash in front of the double quote: sentence.gsub("“",34.chr) => 'This is a quote, \"Hey guys!”'
