I want to use my own Model classes in a repository pattern. I don't want to be dependent on the classes that LINQ to SQL generates. Is that viable? How do I handle the Where (and other selections when its a Func<MyModel, bool> but LINQ to SQL wants a Func<LinqToSqlModel, bool>? I've devised this, but I might be starting to over engineer...

Hello all. Can't figure this one out. In rails model, I want to call a method within the same model to manipulate data returned by a find method. This 'filter' method will be called from many custom find method within this model, so I want it to be separate. (and I cannot filter from the SQL it is too complicated) Here is an example: ...
I'm working on a time management project and looking for some practical object / persistence models. Fowler has some great ideas on resource allocation in his Analysis Patterns book, but many are overkill for what I need right now, and by design, highly conceptual (as opposed to implementable) The focal conceptual object I'm thinking of...
Given the code below, how can default values be defined for the Model. (let's say the default for :name should be 'Thing'). require 'pp' require 'sequel' DB = Sequel.sqlite DB.create_table :items do primary_key :id String :name end items = DB[ :items ] class Item < Sequel::Model end Item.create :name => 'foobar' Item.create ...
I'm writing a small OpenGL demo and I would really like to show some example models with textures. The trouble is I have a really tough time finding such models. There are tons of repositories of 3D models in various formats but it seems that only a small fraction of them have texture coordinates. I'm looking for find some well known st...

The type of query I'm trying to generate is described here. So, let's say I have the following models - class ContactGroup(models.Model): .... whatever .....
Hello, all I want to do, is to fetch the lastest item from my models and have them in an array sorted (freshest items first) by the attribute "updated_at". Somewhere is an error, but I can't find it: @results = Array.new Note.find(:all, :limit => 3, :order => "created_at DESC").each do |item| @results << item end Pictur...
Hello everyone. I have this piece of code in a model that sets a start date and end date according to the time of the day that the method is run. Let's jump right into the code example: #MODEL now = Time.now if now.hour >= 17 && now.hour <= 23 #night n = now+1.day startd = Time.local(now.year, now.month, now.day, 17, 00, 0...
I'm slightly confused about what exactly the Model is limited to. I understand that it works with data from a database and such. Can it be used for anything else though? Take for example an authentication system that sends out an activation email to a user when they register. Where would be the most suitable place to put the code for the...

For those that process data, there is a saying: "If you torture data sufficiently, it will confess to almost anything". This is mathematically supported by the Boferroni's theorem, which states that "as one performs an increasing number of statistical tests, the likelihood of getting an erroneous significant finding (Type I error) also i...
Hi guys, I'm trying to get my models related using ReferenceProperty, but not have a huge amount of luck. I have 3 levels: Group, Topic, then Pros, and Cons. As in a Group houses many topics, and within each topic could be many Pros and Cons. I am able to store new Groups nice and fine, but I don't have any idea how to store topics und...
Hello everyone. Here's my question for today. I'm building (for fun) a simple templating engine. The basic idea is that I have a tag like this {blog:content} and I break it in a method and a action. The problem is when I want to call a static variable dynamically, I get the following error . Parse error: parse error, expecting `','' or ...
I've enjoyed building out a couple simple applications on the GAE, but now I'm stumped about how to architect a music collection organizer on the app engine. In brief, I can't figure out how to filter on multiple properties while sorting on another. Let's assume the core model is an Album that contains several properties, including: ...
