Hi Just something that I have been finding very helpful sometimes when I am stuck with "how could I test this?" moments is looking at the Rails test suite. At the moment I am working on testing our custom error_messages_for methods and I have found looking at how the Rails tests in active_record_helper work helpful :-) So just thought I''d share that. Have

Hello all I would like to overload the error_message_on method in the ActiveRecordHelper module in order to emit a span tag instead of a div tag. I try to achieve this by way of plugins: Under vendor/plugins I''ve made a error_messages_on_fix directory, containing init.rb like this: --- require ''active_record_helper_fix'' --- ..and a lib directory with

Hi guys, I just upgraded to the latest version of Rails 1.1 and am getting some odd error messages. Specifically, I have the line: <%= error_messages_for ''user'' %> at the top of one of my .rhtml files and of course a variable @user. When an error occurs when saving ''user'', instead of getting the error message (which happened fine in Rails 1.0), I now

Hey All ! I have a form which contains two models. I would like both models to be validated, but have their validations aggregated on the page. If I do: <%= error_messages_for(:model1) %> <%= error_messages_for(:model2) %> It puts two big validation blocks on the page. I would like all the errors from both models, but only in one validation box. Is this possible ? All my attempts

Hi! I need to run ols regressions with Huber-White sandwich estimators and the correponding standard errors, without an intercept. What I'm trying to do is create an ols object and then use the robcov() function, on the order of: f <- ols(depvar ~ ind1 + ind2, x=TRUE) robcov(f) However, when I go f <- ols(depvar ~ ind1 + ind2 -1, x=TRUE) I get the following error: Error in

Greetings, I''m in the throws of deploying an app on site5, and I''m getting strange errors. I think I might need to understand how error_messages_for works.

The error occured while evaluating nil.errors Extracted

Dear friends, In S-PLUS, we can use the following argument, but not in R. mode12 <- gam(score1 ~ lo(latitude) + lo(longitude)) I searched the help in S-PLUS, it says lo() Allows the user to specify a Loess fit in a GAM formula, but i didn't find the correponding function in R. Anybody knows how to do the similar task in R? Thanks very much. -- With Kind Regards, oooO:::::::::

Hi, as it is not possible for me to use a sensible development environment to start with I have to use emulations. I use Cygwin on windows and also Colinux. (Colinux is really amazing cause it lets you run actual linux binaries und Windows.) So here is my problem, which by the way exists since Rails 0.5.0 I think. It was the reason I tried Colinux in the first place, cause the error first

My authentication (signup/login) is up and running in my app, now I need to implement an authorisation system. Its not going to be a complex one.

Hi All, I created a new rails application using rails 1.0. I used "ruby script\generate scaffold" for each of my tables. This worked on all but 2 of my tables. When I go to the new or edit action of my requests or admins table, I get the error below. On one table called admins I hadn''t followed the correct naming convention and wasn''t able to edit or create

Dear All Sorry for this simple question, I could not solve it by spending days. My data looks like this: # data set.seed(1234) clvar <- c( rep(1, 10), rep(2, 10), rep(3, 10), rep(4, 10)) # I have 100 level for this factor var; yvar <- rnorm(40, 10,6); var1 <- rnorm(40, 10,4); var2 <- rnorm(40, 10,4); var3 <- rnorm(40, 5, 2); var4 <- rnorm(40, 10, 3); var5 <- rnorm(40, 15,

I have an application that is using active record outside of rails. the app works fine w/o the activerecord code, but when I added activerecord to the mix I started having trouble with constants not being recognized, e.g.: [echo] 1) Error: [echo] test_pipeline_cruncher(IntradayCruncher::TestPipelineCruncher): [echo] NameError: uninitialized constant INFO [echo]

Hi All, I have a problem with the stemming(?) in rails. I have a table cookie and a Cookie model which I have generated a scaffold for. The problem is that rails starts looking for a file that it calls "cooky.rb", this must be some kind of misunderstanding between me and rails, but how do I correct it? Other scaffolds work just fine. /Hugo NameError in Cookie#index uninitialized

Dear List, Does anyone know how to simulate data from a GLM object correponding to values of the independent (x) variable that do not occur in the original dataset? I have tried using simulate(), but it generates a new value of the dependent variable corresponding to each of the original x-values, which is not what I need. Ideally I whould like to simulate new values for GLM objects

Consider all the text that one sees on the console during an R session. Is there a way, within R, to make all this text--both the "output" and the "messages"--automatically get copied to a single text file, in addition to seeing it on the console? If I remember to save the console to a file at the end of my R session, that does it. But (1) That requires pointing and
