Hello. I've been evaluating MindScape Lightspeed for the purpose of Model creation. So far I am satisfied. I was further looking for OOTB (actually some professional quality code) providers for MySQL for ASP.Net. I've come across 'dotconnect for MySQL' from Devart. This looks like fitting the bill for the latter requirement. It also has ...
Hi I have a stationary time series to which I want to fit a linear model with an autoregressive term to correct for serial correlation, i.e. using the formula At = c1*Bt + c2*Ct + ut, where ut = r*ut-1 + et (ut is an AR(1) term to correct for serial correlation in the error terms) Does anyone know what to use in R to model this? Than...
Besides the fact that Rails incorporates the database layer into the unit tests (which then is strictly not a unit test), what if I test for model interdependencies, e.g. check if has_many/belongs_to with :dependent => :destroy really destroys the associated items or items from join models to not leave orphans around? Should such a test...

What would be the best way around this? Sh...

Desc Model belongsTo Prod Model. I want that all Prod.Name will appear as checkboxes when adding a new desc, so that user will just click a Prod.Name when adding a new description for it.

The goal is to store activities such as inserting, updating, and deleting business records. One solution I'm considering is to use one table per record to be tracked. Here is a simplified example: CREATE TABLE ActivityTypes ( TypeId int IDENTITY(1,1) NOT NULL, TypeName nvarchar(50) NOT ...
Here's a simplification of my real models in ASP.NET MVC, that I think will help focus in on the problem: Let's say I have these two domain objects: public class ObjectA { public ObjectB ObjectB; } public class ObjectB { } I also have a view that will allow me to create a new ObjectA and that includes selecting one ObjectB from ...

The SQL database is only managed by a model through methods the programmer gives him like: "Hey we have name reco...
Hi I just started with ASP.NET MVC 1.0. I've read through some tutorials but I don't have any good ideas on how to build my model. I've been experimenting with LINQ to SQL. Can't say I like it that much, but I'll give it a try. I prefer using SQL Stored Procedures, but it doesn't seem to work very good together with the optional parame...
Hello, Is there any working automatic model generator for creating a model from existing database? Something like symfony's task symfony doctrine:build-model. I found just Dr Nic’s magic model generator but it doesn't work with rails 2.3+. Please do not recommend Dr Nic's magic models. That's not what I want. I don't believe that ther...
Using django, say I have model classes A and B, representing different types of Companies. Each Company may have multiple Users associated with it. Obviously I'd like to use django's User model, to get the login, etc. goodness. How would I go about doing that? Would I add a UserProfile that has two foreign keys, one to A and one to B...

I'm writing an application in Qt (with C++) and I need to represent an object structure in a tree view. One of the ways to do this is to create a model for this, but I'm still quite confused after reading the Qt documentation about the subject. The "structure" I have is pretty simple - there's a Project object that holds Task objects in...
