How do you roll back a failed rails migration? I would expect that rake db:rollback would undo the failed migration, but no, it rolls back the previous migration (the failed migration minus one). And rake db:migrate:down VERSION=myfailedmigration doesn't work either. I've ran into this a few times and it's very frustrating. Here's a simp...

Only certain users can no longer receive notifications from my app. I was able to re-produce this with a test account but I dont know how and removing/adding the application doesn't seem to fix the problem. This application is only being used by 4-5 testers and the number of notifications being sent to any given user is very nominal and...
In ruby on rails, all has_many :widgets methods generate both a object.widgets method and an object.widget_ids method. The latter method is very useful because it bypasses the creation of ActiveRecord objects and runs a much faster query. The query speed can be improved by using the :select option, but ruby still allocates much more mem...

I followed the README and everything seemed to be going well, but now I'm trying to associate a User with a Role and it fails. Here's the ...
I've done some dabbling in Rails, but I see a lot more jobs wanting/using PHP than I do Rails. I really know neither of these that well (most of my "professional" experience has been hacking around with Classic ASP and some minor dabbling with ASP.NET; I'm comfortable with OOP and C#/VB.NET), but to maximize my job opportunities I'm hig...

To be sure I have logged hex versions of the data that is hashed to the console at both the Rails and Cocoa sides, and they match exactly. Here's the Cocoa part: #import <CommonCrypto/C...

Does anyone know where the method is defined? I've pretty much search all of the generated code, and still don'...
