Hi, I am thinking about how to best design a quiz site in RoR. I think it should be fairly easy, but have run into a wall. In the simplest form, the view would grab all of the questions for a particular quiz and display them (e.g. multiple choice, so 4 option buttons per question). However, I can''t figure out how to "mark" the quiz. The form is submitted to the

I am building a relatively trivial application to try to learn my way around Rails. I am having difficulty understanding how to navigate a heavily denormalized hierarchy. Could someone direct me to a bare-bones explanation of using rails to navigate database hierarchies? I am an experienced developer. Most of my work has been desktop client server, high performance, or server to server

Hey, I just put up a little rails pop-quiz on my blog (more fun than just writing a post saying "hey did you know..."). Seeing as it''s probably of interest to more than just the three people (including my wife) that actually read my blog I figured it would be okay to announce it here. http://tinyurl.com/prxdl I''ll post my answers in a followup tomorrow

Railsriders: Quizmeister James Edward Gray II selected the best 25 Ruby Quizzes from last year, then carefully collected answers and annotated them. The result is "The Best of Ruby Quiz", a wonderful book which will teach any Ruby programmer new techniques and approaches to coding. If you want to hone your programming skills, stick to the front part of the book and enjoy

I was implementing dirty checking for an application, and I found something that is a little counterintuitive. Let me start with a quick quiz: bob=User.find(1) alice=User.find(2) trip=Trip.new trip.driver=bob old_driver=trip.driver trip.driver=alice In this example, who is old_driver? If you guessed Alice, you''re right. Inside associations.rb, the mutator is defined as:

Today, I was looking for an elegant (and efficient) way to get a named (atomic) vector by selecting one column of a data frame. Of course, the vector names must be the rownames of the data frame. Ok, here is the quiz, I know one quite "cute"/"slick" answer, but was wondering if there are obvious better ones, and also if this should not become more idiomatic (hence

I am trying to create, display and edit a referenced object''s text field on the same view as my root object. I have just about come to the conclusion that whoever invented of taglibs should be shot. quiz.preamble_presentation references a Presentation object instance. The Presentation object contains a property called text, among others. The generated form will display the ID of the

Hi all, I''m looking for some advice on where we should be putting an advert if we are looking to hire a full time rails developer? Or turning it around what websites (or mailing lists) do folks here use to if they feel the need for a change in view from their desk? A few details to narrow down scope since it might affect the advice, apologies in advance, trying to NOT make this an

Dear expeRts, I would like to create a plotmath-label of the form X_1^\prime. Here is how to *not* do it [not nicely aligned symbols]: plot(0,0,main=expression(italic(X*minute[1]))) plot(0,0,main=expression(italic(X[1]*minute))) plot(0,0,main=expression(italic(X)[1]*minute)) Any suggestions? Cheers, Marius

I offer my apologies in advance for the repost. On a list as busy as this, it is sometimes easy to get missed in the shuffle. I am trying to create, display and edit a referenced object''s text field on the same view as my root object. For example: ------------------------- Quiz: <<quiz.name>> Preamble: <<quiz.preamble_presentation.text>> Postamble:

I have a real-world application with some complex queries that I want to convert to Arel (as part of an upgrade to Rails 3.1). So that I can understand what I''m doing before I flail around in my real app, I wrote a little sample app (just the models) with some similar associations -- one table joined with itself and more tables that join to another table, so there are some queries that

I am successfully navigating between controllers. However, I am unable to construct a new child (question) record. What does "undefined method `stringify_keys!'' really mean"? I think I am missing a subtlety of Ruby syntax here, since the question_controller is actually trying to call the Question constructor. Can someone point out what I am missing please? Thanks in

This has the look of a "just don''t quite get it yet" problem. I am using the ActiveRecord.find_by_id method to identify the parent object (Quiz) to tie to the child object (Question) at create time. Here is the stdout log: 127.0.0.1 - - [31/Mar/2006:22:43:22 CST] "GET /question/new? parent_quiz=ff2d7022-be0a-11da-9f01-00400506faf5 HTTP/1.1" 200 806

I am using ruby 1.8.4 with rails 1.0 under fedora core 3 on a WIntel platform. Rails appears to be losing key information under some circumstances. Specifically, in the Questions class that follows, the presentation_id property is apparently being lost. The STDOUT dump from the create method indicates that the presentation_id should be 42, but the dump from the database shows that it is 43,

If you look at the FileCheck documentation page: http://llvm.org/docs/CommandGuide/FileCheck.html you'll find this intriguing example of combining -DAG with -NOT (slightly amended to avoid some potential confusion): ; CHECK-DAG: BEFORE ; CHECK-NOT: BETWEEN ; CHECK-DAG: AFTER The page says this will reject the sequence "AFTER BEFORE", which is correct. It's intuitively obvious
