similar to: Subclassing a model

Hi! I have two models, artists and songs. I have this in my route file: resources :artists, :path => "ackord" do resources :songs end Which gives me urls like this (I''m using https://github.com/norman/friendly_id to create and manage slugs): example.com/ackord/artistname/songs/songname-id Now I want to remove the /songs part to get a url like this:

Having problems with STI. Names below have been changed to protect the innocent. Imagine a system that allows someone to apply for one of two different types of school scholarships. Each scholarship goes through a different review process, represented by a state machine (this is not a state machine question). So there are two state machine classes that differ slightly and subclass a generic

First of all, sorry for the crossposting, but I put this into the Ruby Forum first of all, but was pointed to this as a more appropriate location. I''m using ActiveRecord and ActiveSupport in a non-rails environment to connect to multiple databases, and I''ve found the following (single database) to cause me an error. Note that params is my database settings and omitted for

when using prototype and Class.create(), what''s the preferred method of creating a subclass? say I have a real simple class: var Testing = Class.create(); Object.extend(Testing.prototype, { initialize: function() { ... }, ... }); would I subclass it as so? var SubClass = Class.create(); Object.extend(Object.extend(SubCLass.prototype, Testing.prototype), { ...

I need to create a subclass that derives from MCELFStreamer. We use MCELFStreamer for direct object generation and need to override a virtual method in the base class MCStreamer::EmitGPRel32Value(). I have been having trouble creating the subclass due to #include issues. I can't seem to get it right at the lib/target/<my target>/MCTargetDesc level. My first thought is always that I am

I''m new to Rails3, and I''m just trying to get one last thing to work before I call it a night. The situation is the following (please if the code is horrible, just let me know, still learning): I want to log a dive. I might have a new location on that dive at which point I have to create a new Location, and then create the dive. A dive has_one location. A location has_many

I''m about to embark on a project and am seeking advice on my approach. I have an automotive site that needs to have shared categories. I''ve checked out different nested set, ancestral, acts_as_tree, acyclic plugins but feel they don''t exactly fit. So I am about to roll my own simple solution. Any feedback as to whether this looks good is appreciated. Essentially I

Hi Jack, Can you elaborate a bit on what you're trying to do? Relocations are handled by the ObjectWriter interfaces, not by the streamer. The <ObjectFormat>Streamer classes aren't intended to be subclassed by targets. -Jim On Nov 14, 2011, at 5:50 PM, Carter, Jack wrote: > I need to create a subclass that derives from MCELFStreamer. > > We use MCELFStreamer for direct

I'd trying to subclass the "lm" class to produce a "mylm" class whose instances behave like lm objects (are accepted by methods like summary.lm) but have additional data or slots of my own design. For starters: setClass("mylm", "lm") produces the somewhat cryptic: Warning message: Old-style (``S3'') class "mylm" supplied as a

Hi, I think it would be great if we could subclass the LayoutPass. All the generic functionality could be in the parent to run the layout-after/in-group/ and currently the layout-before passes(until it gets removed). Flavors can *choose to run the layout passes* that they use and determine the way things get ordered in the layout pass. The compare function in the LayoutPass would call

A lot has been posted about validation issues with associations, however, I don''t see this issue addressed specifically. ex: class Foo has_one :schedule, :dependent => :destroy validates_presence_of :schedule class Schedule belongs_to :foo validates_presence_of :foo_id this creates a circular dependency that breaks test frameworks like pickle and machinist. At first I was

Well Jim, that may just be my problem. As background I am working on the outer reaches of llvm for the direct object output for Mips. Part of what I am to do is instruct the folks working closer to the backend what I am getting that is incorrect. My first reaction is to assume that I am being fed things the correct way and that I am not handling it correctly. I feed the compiler a source file

Hi Jack, I'm not 100% up on how MIPS represents jump tables, so take with a grain of salt and all that. Normally how this stuff works is that the streamer will create Fixups (MCDataFragment::addFixup()) for anything that might require a relocation. That may come from the generic streamer stuff (see MCObjectStreamer::EmitValueImpl() for example), or from the target's MCCodeEmitter (for

Jim, Ok, you are where I am in the understanding. This is exactly what I do for relocations applied to code. Now I want to apply fixup information to relocations applied to data. The issue I was having was the difficulty of subclassing MCELFStreamer. Or are you saying that I should be messing with the base MCELFStreamer for a specific fixup. One of the issues I hit initially with llvm is that

Hi, I want some of my models to inherit from a custom ActiveRecord::Base class. Where is the best place to put this custom subclass? Actually, I just wanted to translate the default validate message so maybe there was a better thing to do than subclassing ActiveRecord::Base.

Hi, I''m sure there is an easy way to do this, but I just can''t see it: I have a large amount of rooms, that are for different purposes, and for only one ''purpose'' do I want to create a specific subclass. Ex: banquet,wedding,admin. I want to have additional information about admin rooms. Trying to use the ''type'' field just gives an error

Hi Jim, Daniel, The last time the topic of subclassing MCELFStreamer came up, you both were helpful in identifying ways to handle the use case without requiring subclassing. Can you please take a look at the context below and let me know if you have any suggestions? For reference, this was posted to the list yesterday under the subject "sub-classing MCObjectStreamer?": > Okay,
