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 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, 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

Hey Everyone, I'm pretty new at R and wanted to try and make some graphs with dummy data before using it to analyze my own. I successfully made a bar graph and error bars, but I can't figure out how to align them properly (currently they are not centered on the bars and some of them aren't even close). Here's the code that I'm using: > marks <- sample(4:10, size=50,

It looks like I am missing something obvious. ActiveRecord is generating _really_ bad SQL for this configuration, and I can''t quite figure it out. I''ve instrumented ActiveRecord enough to localize the problem somewhat, and generally by this time I would have a good idea of what I was missing because it''s all in the source. It appears that something in

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,

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

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.

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

Hi, Should I be able to use the Webrick postamble instead of using .campingrc, to tell Camping I want to use mysql? It doesn''t seem to be working for me. It does work however, when I''m using FastCGI (establish_connection :adapter => ''mysql''). James

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

For some reason, rails is generating this SQL: SELECT FIRST 1 * FROM questions WHERE (parent_id IS NULL) ORDER BY position DESC 1. There is no column named position referenced in my code. 2. POSITION is a reserved word in SQL92. It is the name of a string function that returns the offset of one string within another. I believe that this is a bug in Rails. Either position should be

Hello, We have been working with the ReceiveFax application for some weeks now in order to receive faxes in T.38 and it works fairly well, but there are some faxes that for some reason we are not able to receive correctly. The asterisk version we are using is 1.6.0.6 with spandsp-0.0.5pre4 and the asterisk machine is behind a CISCO mediaGW to be able to communicate with the PSTN. The SIP call

Ok, I *might* be getting this from the assembly code. The assembly code has: L_llvm_gc_root_chain$non_lazy_ptr: .indirect_symbol _llvm_gc_root_chain .long 0 and I see it being used in the function preamble. Is that a ref to an extern symbol or the def? I.e., is it referring to StackEntry *llvm_gc_root_chain; that I must have in my GC C code? (semispace.c has it) SO!

Hi, I work on MacOS, trying to Sweave an UFT8 document. AFAI remember R 2.14 used to render a warning when the encoding was not declared when using Sweave. With R 2.15 it seems to render an error. Sweave("sim_pi.Rnw") Error: 'sim_pi.Rnw' is not ASCII and does not declare an encoding Declaring an encoding by adding a line like \usepackage[utf8]{inputenc} in the preamble does

Hello list, We're currently facing some issues concerning T.38 gateway faxing. This is a device used almost exclusively for receiving faxes. Calls are incoming to asterisk on a SIP trunk (sangoma netborder) using G711A. Gateway mode is activated in the asterisk dialplan towards a Cisco SPA 112 running firmware 1.3.5. We are using asterisk 1.8.13.0 with the T.38 gateway patch applied (I know I

Hi there, My name is Angelica and I was just checking out your page at http://us1.samba.org/samba/docs/SambaIntro.html and noticed that the the link to the Dilbert site on http://www.unitedmedia.com/comics/dilbert/ isn't working.
