So I know that you shouldn't use UrlWriter methods in a model, but I wasn't sure what a better way to handle my current situation is. Basically, I want to allow a User to post something to his facebook feed, and want to write a post_to_fb_feed(object) method in class User. Now, the URL of what is actually posted depends on the object, s...

I've read this somewhere but I can't find it now. I'm trying to change the default "find" method on a model from the id to for example the name. So when I map resources to a model it uses the the name instead of the id. I don't remember if this was a parameter in the resources command in the route file or if it was something you added ...
I'm trying to write a function to SELECT the least-recently fetched value from a table in my database. I do this by SELECTing a row and then immediately changing the last_used field. Because this involves a SELECT and UPDATE, I'm trying to do this with locks. The locks are to ensure that concurrent executions of this query won't opera...

Say I use a simple frontend for information passed on by a DAO that uses JDBC (without ORM). In other words, the class would have no attributes to speak of. Would this considered as a valid approach? What issues could it potentially cause and how could a class be designed to avoid them? ...
I'm pretty new to MVC, I'm trying to create a model that can be localized, but it doesn't seem like that would be possible given that I have to use a custom property attribute to define displayname and validation properties. Is there a way to dynamically create the model metadata attributes (DisplayName, UIHint, etc..) as opposed to h...

Lots out there about changing model names only or mapping new models to existing tables, but nothing about renaming both at the same time.
