I am developing an Rails 2.3.1 Web site. Throughout the Web site, I need to have a form for creating Posts on various pages (Home page, Create Posts page, Post listing page, Comment listing page, etc. -- suffice to say this form needs to be on many pages served by a variety of controllers). Each of these pages displays a wide variety of ...
I have overridden the SimpleHandler to pass a username and password using soap4r. the problem is that I am forced to give a QName, and this is causing the result to fail because it's not in the right format. What soap4r is adding is something like this (the "ns1" things are dummy values): <env:Header> <n1:ns1 env:mustUnderstand="0" ...
Here's something I often do when programming: code = '' code << "next line of code #{something}" << "\n" code << "another line #{some_included_expression}" << "\n" Is there some better way than having << "\n" or + "\n" on every line? This seems quite inefficient. I'm interested in Ruby solutions, in particular. I'm thinking something...

I have a problem in trying to link a stand with two checkboxes which are resident & communication, and they seem to be stored separately if more than one stand is choosen. If I have one stand the parameters seem to be stored in the correct manner inside a hash of an array, but once I add another stand to that same array it seems to swap...
I came across this method called record that Ryan bates uses in his authlogic Railscast and can't seem to understand what it does.

Does anyone know how to delete all files in a directory with Ruby. My script works well when there are no hidden files but when there are (i.e .svn files) I cannot delete them and Ruby raises the Errno::ENOTEMPTY error. How do I do that ?? Thanks in advance. ...
So I would like my Rails app instances to register themselves on a "I'm up" kind of thing I'm playing with, and I'd like it to be able to mention what local port it's running on. I can't seem to find how to do it - in fact just finding out its IP is tricky and needs a bit of a hack. But no problem, I have the IP - but how can I find wha...
Just briefly, why are the following three lines not identical in their impact? if @controller.controller_name == "projects" || @controller.controller_name == "parts" if @controller.controller_name == ("projects" || "parts") if @controller.controller_name == "projects" || "parts" The first gives me the result I want, but as there's a...

First time poster. Back to programming after being away for a few years, trying to clean off the rust. I'm creating a dashboard that will run initially on my laptop (Macbook Pro, 10.4.x O/S). Amongst other things I want it to retrieve latest information from my online accounts. I'm starting with html, but will probably migrate to som...
