Just started learning Rails (3). I am tearing my hair out trying to find how to do something presumably utterly trivial: access the value of a model instance's field, from inside a method on that model. In my case: def formal_name @title + " " + @forename + " " + @surname end All three @properties (which are all fields on the tabl...

I am writing a Rails back-end API for a Steam game that is only accessed via REST calls, so no user-specific authentication is required.

Here is the Ruby code I'm working wit...

I'd like a very basic example of a tiny base program, that reads in two plugins and registers them. These two plugins hook into the base program in the same way in a unconflicting manner. I'm very new to metaprogramming in any programming language for that matter, I'm not sure where to start. ...
I'm new to MVC. I'm using Padrino with MongoMapper and Haml to try to create this application. I have a database of items, each of which has a hash associated with it called 'params'. This hash has some required keys, but mostly arbitrary/random keys. Some of the keys have a finite set of allowable values. For example: item.params["pa...

Somehow, I was under impression that accepts_nested_attributes_for will let me populate child object through parent: person.update_attributes person_hash but in practice I ended up doing this: person.address.update_attributes person_hash[:address] person_hash.delete :address person.update_attributes person_hash Now, http://guid...
