...pment. My idea of a perfect screen is plain white that is sparsely populated with black text with a single font and no effects. The default stylesheets that rails generates are quite a bit more elaborate than I would choose to build :o) I am trying to build a flash-card application that contains quizzes, questions, possible answers, and presentations, plus historical records of users''s answers over time (quiz_instances, question_instances, response_instances). I have been working from Thomas and Hansson (Agile Web Development With Rails), but I appear to be missing something in the move...

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

Hi In my app , a user can create a set of question then a table is dynamily created , in the database,to store the answers of the questions. the name of the table is answers_x (x is the id of the questionniare). Is it possible to dynamicly create a model, to handle the answer_x tables ?? I can''t manually create a model then restart the server.

...html and noticed that the the link to the Dilbert site on http://www.unitedmedia.com/comics/dilbert/ isn't working. I'm a Dilbert fan myself :) so I thought I'd mention a page I have bookmarked: http://www.answerconnect.com/articles/dilbert-fans It has a bunch of neat fan sites and quizzes and whatnot. I figured it might be a good addition to your page, if you were going to replace that dead link. Hope I could be of some help. Have a good day! -Angelica

Sorry to keep quizzing the r-helpers but I'm having real difficulty with arima. I am happy that i have chosen the best fitting arima model for my data,(in this case arima(1,1,1) but when i use the predict function the forecast damps to a constant value after just two or three values, and from a time series of almost 3000 values i am left with only a couple of predicted values. I have tried

I've been asked by someone else whom I originally taught `` to just work with substitute() and then all will be fine'' ... But it looks to me that I've been caught here. Is it possible to make this work along the way we thought it should? 1) Inside a function, say tst() with the 'formula' and a 'data' argument, 2) call another modeling function using

I have a magical proposal for the anti-magic web framework. Controller methods do not use arguments and yet expect arguments. This is handled through this params hash because we don''t know in advance what parameters a client could pass to Merb. But in almost every instance, it is too much to know all the query parameters - one doesn''t care if the user threw in an extraneous
