I submitted this earlier, but the web forums went down and I''ve screwed up the thread, so I''m starting over. I''m trying to built a document upload system. The system has a main Document model with different subclasses for different types of documents. With the code below, if I attempt to create a Document, it works fine, but if I attempt to use one of the subclasses, I

Hello: I recall something like this being discuss recently, but I can't seem to locate an example in the archives. I have data like the following: df <- expand.grid(1:4, 1992:2002) names(df) <- c("MSA", "YEAR") df$IDUPREV <- runif(44) df$VALIDAT <- rnorm(44) I want to create an xyplot() with separate loess lines for each series (IDUPREV and VALIDAT) in

Hi, I''d really appreciate someone looking at some specifications I have. The context in each case is realised in the setup block (I''m assuming this is standard practice?). The specifications should be self-explanatory. I''m wondering if anyone can see anything obviously bad/wrong with what I have? I''m intentionally not stating anything else as in theory the

I''m trying to create a document upload system, where most of the code is the super class Document and just the path to file on the system is controlled by the sub classes. When I attempt to use my code, I get the following when I try to save the document. can''t dump anonymous class Class Any ideas? ** Migration ** class CreateDocuments < ActiveRecord::Migration def

Sometimes I want to show just one error, even when a field fails two or three validations. A custom validation method is easy enough, but the helpers are nice and concise. So, has anyone found a way of doing this with AR''s validation helpers? The :if/:unless look promising, but its made harder by validations being applied in a random order. - Andy P.s. The validatable gem has the

Hi there, I''m solving the problem about the plugin Magick.

I''ve found myself mocking out a published api in my set-up method. This has led to some contexts having a large set-up and empty specifications. As the mocks get auto-verified, the specification blocks have nothing to do but serve as documentation. Does this sound bad? Chris

I like have_one a lot. It speaks to me as a Rails developer and I think it speaks to

Is there an expert validater that can point me in the right direction? I''ve looked for extended documentation on ''validates_presence_of'' but i can''t seem to find any. I''m trying to make sure that i don''t enter a nil object in my database, so i''ve added validate...

Dear list I am using the mvr function of the package pls.pcr to compute PLS resgression using a X matrix of gene expression variables and a Y matrix of medical varaibles. I would like to obtain the R2 (sum of squares captured by the model) and Q2 (proportion of total sum of squares captured in leave-one-out cross validation) of the model. I am not sure if there are specific slots in the

What version of R, what version of pls.pcr, and on what OS? Have you checked whether your versions of software are up to date? I get: > n <- 1350 > p <- 180 > y <- rnorm(n) > x <- matrix(sample(0:1, n*p, replace=TRUE), n, p) > fit <- mvr(x, y, method="SIMPLS", validat="none", ncomp=2) > xt <- matrix(sample(0:1, 312*p, replace=TRUE), 312,

ActiveRecord supports composed_of for value objects which is fantastic but one thing that it doesn''t seem to support (or at least I am unable to find any documentation for) validation of the value objects. For example, given the following: class Message < ActiveRecord::Base composed_of :sender, :class_name => ''EmailAddress'' composed_of :recipient,

If I have belongs_to :user Do I need to have validates_presence_of :user_id ? Does Rails validate the presence of :user_id automatically if I have belongs_to :user? In other words, does Rails prevent against creating orphan records that belong to non-existent users? Thanks. -- Posted via http://www.ruby-forum.com/.

Hello everyone, I am new to rails and I am having some trouble getting the Devise authorization plugin working. I can get the login page to display, but when I enter the credentials for a known user (I seeded an account to the database) it just says "Invalid email or password," even though I''m 100% sure I entered the right information, and redirects me to the login form.
