For this, I want to create a command-line application in Ruby (not Rails), which will check if there were made any changes, then upload changed or new f...
I have a Rails (2.3.5) application where there are many groups, and each Group has_many People. I have a Group edit form where users can create new people.

I am trying to find a way to contribute back to rails. I was thinking I should validate if this patch https://rails.lighthouseapp.com/projects/8994/tickets/4154-expires_now-broken works or not.

Hi, I'm using rails 2.2.2 on a linux box and am using a rake task to send some emails. It's a very simple script without error handling: 1.) Get emails to send 2.) Send email 3.)

I know the user needs to give the application "extended permission" for access to the email address. I went through the Facebooker documentation (I am using it for an iFrame app for whatever it's worth) but can't find any related stuff in the documentation or any sample code. ...

We have two separate rails_app, foo/ and bar/ (separate for good reason). They both depend on some models, etc. in a common/ folder, currently parallel to foo and bar. Our current svn setup uses svn:externals to share common/. This weekend we wanted to try out git. After much research, it appears that the "kosher" way to solve this is u...

I'm trying to update the to_xml method so that if a child record's to_xml is called it will return it's xml nested in the parent/ancestor xml to give the fully-qualified path to that resource. As an example I have Compiler which is a parent of Compiler/Version. Compiler should be re...

Is Rails 3 ready to use in Production? I know is in beta (currently beta 3), but is it suitable to build a simple app using authentication (devise)? Or should I wait for a final version? What is your opinion? Thanks ...
