Why can''t I access an associated model in a validate method? I have some code that looks like the following: Models: class Product < ActiveRecord::Base has_many: upcs end class Upc < ActiveRecord::Base belongs_to :product def validate errors.add_on_blank(''upc'') unless product.new_record? end end Controller: def create @product =

Hi, I have configured two machines for testing gfs filesystems. They are attached to a iscsi device and centos versions are: CentOS release 5.4 (Final) Linux node1.fib.upc.es 2.6.18-164.el5 #1 SMP Thu Sep 3 03:33:56 EDT 2009 i686 i686 i386 GNU/Linux The problem is if I try to mount a gfs partition it hangs.

Dear all, I've found a bug report for R when installing it on an AIX5.1 system. There's a followup (number 4) that comments a segmentation fault on R when quitting "q()". I'm using a newer version of R but on the same operating system and I obtain the same error. There was a way to solve this problem? Best regards and thanks, --

We're using an internal PAM module (Linux) that sets a few environment variables using pam_putenv (on pam_sm_authenticate). In version 3.6.1p1i such variables are visible to the user (as expected), but since 3.7p1 they are not... Is this the expected behaviour? Thanks in advance, Jose ____________________________________________________________________________ Jose A. Rodriguez

Hi, I'm new to this list (and R), but my impression is that this question is more appropriate here than R-help. I hope that is right. I'm having several issues with the performance of an R script. Occasionally it crashes with the well-known 'Error: cannot allocate vector of size X' (this past time it was 4.8 Gb). When it doesn't crash, CPU usage frequently drops quite low

Hi, We have two nodes with centos 5.5 x64 and cluster+gfs offering samba and NFS services.

Hi all! I''m new on puppet, and I making my firsts classes. I have defined an example class to install 7Zip on Windows servers, it runs right, but I would like to improve it. The problem is that each time that I execute the "puppet agent --test" it downloads the 7zip.msi file, although it is really installed. So, my question is: Is possible to avoid the download of the

Queridos R-users: Tengo una duda que hace mucho tiempo que estoy intentando resolver, os explico a modo de ejemplo: Tengo estos efectos: Año(5 niveles),Localidad (10 niveles) y genotipo (3 niveles), año y localidad son aleatorios y genotipo es fijo (los he escogido yo). Me gustaría hacer obtener una tabla parecida a la Tabla Anova donde aparezca cada factor y sus interacciones y

I'm probably missing something simple here but in: CGDebugInfo.h: std::vector<std::pair<void *, llvm::WeakVH> >ReplaceMap; but then in CGDebugInfo.cpp: llvm::DIType TC = getTypeOrNull(Ty); void * v = Ty.getAsOpaquePtr(); std::pair<void *, llvm::WeakVH> tmp = std::make_pair(v, TC); if (TC.Verify() && TC.isForwardDecl())

Hi, I wish to write a new link function for a GLM. R's glm routine does not supply the "loglog" link. I modified the make.link function adding the code: }, loglog = { linkfun <- function(mu) -log(-log(mu)) linkinv <- function(eta) exp(-exp(-eta)) mu.eta <- function(eta) exp(-exp(-eta)-eta) valideta <- function(eta) all(eta != 0)

Hello, I am working in a project on a parallel programming language. I want to base our language on Java or C/C++. But Java is preferred. Many similar projects adopts a source-to-source methodology, e.g., Berkeley UPC(using Open64), Titanium, and Rice University's Co-array Fortran. They output C code with calls to the runtime. I think there are at least three reasons: 1) using C as the

Hi Ben, Thanks that helped a lot. The problem seems to be that with the move to C++11 we now have: void std::vector<_Ty>::push_back(std::pair<_Ty1,_Ty2> &&)' and there no conversion operator that can be applied to convert: 'std::pair<_Ty1,_Ty2>' to 'std::pair<_Ty3,_Ty4> && Where: [ _Ty1=void *,
