Hello. I'm trying to create a registration form with Rails. It's working, but it doesn't displays the errors from the validation (it validates, but the errors don't display). Here are my files: # new.html.erb <h1>New user</h1> <% form_for :user, :url =>{:action=>"new", :controller=>"users"} do |f| %> <%= f.error_messages %> <p> ...
The situation is that I'm trying to write a server script that accepts file transfers from a client. I figured out how to make and connect to and from the server using the TCP protocol. However I was wondering how do you transfer a binary file in ruby? I mean you can open a binary file, but what steps are necessary to be able to transfe...
Hi all, I could use some help figuring out what's going on. Check the log output below -- why would rails treat the two renders differently? Why does one succeed, without any related SQL calls and the second fail -- with an SQL access. (It's not an ActiveRecord model, no SQL should be involved in this render.) Background I have a cu...
Hi all, I'm using restclient for a multipart form to send data to a restful web service (it's Panda video encoding service). The trick though, is that the file I am passing into restclient (Technoweenie branch) is coming from my own form that a user submits. So, lets walk through this. A user posts a file to my rails app. In my control...
I'm working on a GUI for Windows XP. Everything works great, except when I run an external command through backticks, %x(), IO.popen, etc, I get a DOS window that pops up for a split second. I know this doesn't happen when I've developed on OS X and Linux. Any ideas on how to get rid of it? (Or at least hide it?) I'm using rubyw 1.8...
I have a Ruby CGI (not rails) that picks photos and captions from a web form. My users are very keen on using smart quotes and ligatures, they are pasting from other sources. My web app does not deal well with these non-ASCII characters, is there a quick Ruby string manipulation routine that can get rid of non-ASCII chars? ...
This question contains java and ruby. I have a java program that I make a call to from ruby. This code works under merb perfectly without any modifications. This code will work under irb perfectly by setting $KCODE="UTF8". For the life of me I can not get it to work under phusion passenger -- this is a problem since our production ser...
Is there a way in the Ruby On Rails Routing framework to make a decision about which controller or action to call based on some logic all within a single route? For example, let's say have a url zip/354 and I want to call the foo action if the integer is even and the bar action if the integer is odd. To use pseudo-ruby: map.connect 'z...
I need to have a view able to update an array attribute on a model such that I can dynamically add things on the view to be able to add this. Does that even make sense? Basically a Foo has urls. So in the DB I just have a text datatype that I want to store the comma separated list of urls, and I override the default AR setter and getter...
I'd like some advice on how to best refactor this controller. The controller builds a page of zones and modules. Page has_many zones, zone has_many modules. So zones are just a cluster of modules wrapped in a container. The problem I'm having is that some modules may have some specific queries that I don't want executed on every pag...
In Rail 2.3.2 can I have merb style action definitions: Eg: instead of def show @user = User.find(params[:id]) end Can I have: def show(id) @user = User.find(id) end What kind of crazy monkey patching do I need to do to get this working, note I only need this working for MRI so ParseTree is an option. Note: there is a Rai...

Hey guys, I'm very verrry new to rails. I'm using the autocomplete (plugin) text field to browse through titles of my records.

I'm trying to make a simple search f...
I'm in a situation where I need the ASCII value of a character (for Project Euler question #22, if you want to get specific) and I'm running into an issue. Being new to ruby, I googled it, and found that ? was the way to go - ?A or whatever. But when I incorporate it into my code, the result of that statement is the string "A" - no chara...
If I have 2 different classes with name User, say one in FooModule and other as a model in app/models/user.rb, how do I make sure I am using the correct one? EDIT: FooModule::User would definitely give me the correct one. What I had meant to ask was: If ApplicationController includes FooModule, would User or ::User still give me app/m...

I've been looking at some articles that say that class variables are bad in Ruby. They suggest using the meta-class (or singleton class). This is my sample code class Joe class << self # here we're putting methods in Joe's "meta class" attr_accessor :foo end def self.foo2 end def self.foo2=value end end puts Joe.single...

I tried to use the JSR179 location API to do this, but I was only able to get it to work on a GPS enabled phone.
