• How do I define a foreign key that points to a class of a different name in ActiveRecord with Rails?

  - by Mark

  Hi there, I have a model Follow that defines a user_id and a followed_user_id. If you've used Twitter, this should make sense. I'm trying to make followed_user_id point to a User model, so I can access the user that is being followed through f.followed_user (in the same way that if I have an Entry with belongs_to :user and a user_id column I can use entry.user to get the user.) How can I do this? Thanks!

• Where to place logic in a rich domain model

  - by Fino

  I have a model "news item" which contains text, image etc to display as latest news on several pages in a website. This "news item" can also be posted to Twitter or Facebook. Is it clean to implement a method post inside the news item model and inject the different post implementations as a strategy? Or is it better to have a separate application service for this? Thanks

• How to rotate UIViews?

  - by user717452

  The Twitter app is a tab bar app on the iPhone. Nothing in any of the tabs will rotate, yet, when you click on a link from a tweet, the view controller that is pushed on top of it IS allowed to rotate. The only rotations I have ever doe is from tilting the device, landscape or portrait, but I don't understand how to use 2d transformations and animations to rotate views. How do you rotate any view with that's a subclass of UIView?

• How can i share data/text with other apps that will accept it?

  - by kefs

  I have an app that creates a new data entry in a sqlite db with several columns. I would like to have a simple share button on the final activity so they can share the results (or even a simple text field) with apps that accept it (email, mms, twitter, etc..). I did some reading on ContentProviders but the more I read, the more I'm thinking i'm heading down the wrong path. Any help is appreciated. Thanks!

• How do I call an upside down jQuery.slideDown()?

  - by Mark Rogers

  In the web app I'm working on I want to do a little slide up notification, like on twitter or your desktop. jQuery's .slideDown does exactly what I want, but it's upside down. The .slideUp doesn't execute an upside down version of slideDown. Instead it hides stuff, like after your cleaning up an old message you've displayed with slideDown. So what's the simplest code to do an upside down slideDown() in jQuery?
