Hi, I have a selectbox that updates a given span area when a user selects a value. The selectbox has the option :include_blank => true. The controler will fetch the ID of the selected option in the combo box and sends the description of the item with the same ID. The problem is that the user is able to select the empty option, and the controler will not be able to fecth the ID. This

Hi, I''m trying to get a big picture about what can be done with the mix of these two technologies. My idea would be to use the power of Rails to provide the model and controller functionalities, and use Open Laszlo for the view design. This would provide a better abstraction level for the development of the GUI. Can someone provide me an idea if this is possible what are the

I''m somewhat of a newbie - played with recent versions of rails a few mths ago, but have decided to start from scratch with 1.0. I want to build my new db as much as possible with migrations, so I watched DHH''s migrations movie from rubyonrails.org. A few things confuse me: 1. He generates the model ("post") before running rake db_schema_dump. Is that necessary or

Hi, I have been using maxLik to do some MLE of Geometric Brownian Motion Process and everything has been going fine, but know I have tried to do it with jumps. I have create a vector of jumps and then added this into my log-likelihood equation, know I am getting a message: NA in the initial gradient My codes is hear # n<-length(combinedlr) j<-c(1,2,3,4,5,6,7,8,9,10)

hy, here is my speex encoder/decoder .. the sampleRate i use is 16000 and quality,complexity are at 5. can someone take a look in to the code and see if there is something that is making that robot voice here is a link to colored and numbered code, same as below http://barvanjekode.gama.us/temp/1257361243.html thanx. code ----------------------- #include "codec.h"

Hi, Yesterday I had to walk through the code of a plug-in and perform a minor fix. I confess that I didn''t like the experience. Because the plug-in is in the vendor directory, I had to restart the web server whenever the code changed. How can I debug a plug-in without having to restart the web server whenever the code changes? Thanks, Tiago Franco

Hi, I would like to know if there is a library that provides an API to support map scrolling, like the one available in google maps. This is, I would like to create a user interface where the user is able to see a small part of a large map. It can then move the view, thus observing another part of the map. Additionally, I would also like to provide a zoom mechanism. Thanks in advance. --

Hi, I have a mysql schema with some decimal(20,20) fields. Now, I made a rake db_schema_dump for deployment of my applications on other machines. Rails created a schema.rb with the decimal fields as float. After a rake db_schema_import the fields are just float not decimal. How can I force rails to create decimal(20,20) columns instead of float? Thx. Marc -- Posted via

Oh noes! What do I do? Just installed RoR and SQLite3 yesterday, watched a screencast that said the db_schema_dump will slaughter my enemies and make my poop smell like rainbows.

This is slightly OT for which I apologise in advance, but I was wondering if anyone here has had any problems when making multiple ajax calls at the same time. I''m working on a large Intranet application which makes heavy use of ajax calls and the bugs are flying in from the testers that if they repeatedly click on a link that makes an ajax call then Internet Explorer can fall
