-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I would like to extract an image BLOB from my database and display it alongside some other information on my ''edit'' page. I read the information here http://wiki.rubyonrails.com/rails/show/HowtoUploadFiles and that was really helpful. However, it still isn''t clear to me how I would get access to the image in my views if

Hi, I''m using SQL Server. I have a BIT field. I have a fix and a question.

Stupid activeldap is messing with my mind ;-) rails (3.1.1 activeldap (3.1.0) rubygems-update (1.4.2) I have activerecord (database.yml/postgresql) and activeldap (ldap.yml) as configured sources for my models. I want to add some more things to my models but activeldap is killing my attempts to create migrations... cwhite@nxpc:~/tti_framework$ rails generate migration AddSettings error

Hi, Has anybody tried using the Productize plugin on a recent Rails install? The pages on RubyForge http://rubyforge.org/projects/productize/ seem to indicate the development has sort of stalled, or perhaps it''s stable as can be. Just thought I''d ask for before I give it a go.. Cheers, Jeroen

I jumped into RoR @ about 3 AM. I think I''ve got it running, but need a simple sanity check. I''ve been through as many references as possible, but thought that I''d ask the list here for references. This list sort of almost being "live". _______________________________________________ Rails mailing list Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org

Is class table inheritance possible with MySQL and Rails? I saw John Wilger''s cool yet complicated Postgres implementation. I have looked for a solution, but I can not find one. Are there any plans for class table inheritance for Rails in the future? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups

My needs are far more modest than Capistrano''s capabilities. Also, when working in a shared hosting environment, the Capistrano model can be outside the capabilities allowed by the Web host. I simply need to push selected directories (on a changed-file basis) out to a server. I have about 80% of the code written to do this (I''m considering YAC for the name, with a nod to

1) The Pareto P(alfa) distribution is defined by its density f(x|alfa) =alfa*X^(-alfa-1) over (1 to infinity). Show that it can be generated as the -1/alfa power of a uniforme variate. Plot the histogram and the density. 2) The Poisson distribution P(lambda) is connected to the exponential distribution through the Poisson process in that it can be simulated by generating exponential random

I am just trying to teach myself how to use the mle function in R because it is much better than what is provided in MATLAB. I am following tutorial material from the internet, however, it gives the following errors, does anybody know what is happening to cause such errors, or does anybody know any better tutorial material on this particular subject. >

OK, I''m finally starting to play around with the AWS part of Rails, and I''m running into problems with the functional tests. If I use the generator to create the web service as ./script/generate web_sevice MyTest do_it and then run the unit tests without further editing the code, I get the following error: test_do_it(MyTestControllerApiTest): ArgumentError: illegal

I have a data with 236 observations. After plotting the histogram, I found that it looks like non-central t distribution. I would like to get MLE for mu and df. I found an example to find MLE for gamma distribution from "fitting distributions with R": library(stats4) ## loading package stats4 ll<-function(lambda,alfa) {n<-200 x<-x.gam

Greetings, I''m a newby to both "R"s in RoR. I would like to use Builder::XmlMarkup to generate my pages. If there is a working downloadable example somewhere, that would probably be enough. Otherwise, here''s what I want to do: With the following controller: class AccountsController < ApplicationController layout ''accounts'' model :account

Dear all, I appreciate suggestions for following problem. I wrote to RStudio: plot(c(1,20),c(1,20), xlab = expression(paste(alfa))) or the same happen when I wrote: plot(c(1,20),c(1,20), xlab = expression(alfa)) what happen is, that description under x label is exactly "alpha", not greek letter alfa (?). Please where should I search problem, or what information to sent to list for

Dear R users, I have to call fortran program from within R (R 2.8.1 on ubuntu 8.10 machine). Suppose I have a fortran code like this (this is only a toy model, my working model is far more complex, but input/output is similar) DOUBLE PRECISION FUNCTION model(times, alfa, beta) DOUBLE PRECISION alfa, beta, times model=beta*sin(times)+alfa*cos(times) END FUNCTION which

I have not had a great amount of success installing/updating packages from the "Packages" menu of Rgui under Windows XL. (Except for installing from loacal zip files.) But I am not asking for help in using these facilities because I prefer to keep a folder of package zip files. On the other hand I do find it tedious having to right-click "Save link as" on every individual

Here''s the text of a quick note I''ve added to the Inheritance wiki page. I''m actually proposing that it would be a good idea to drop automatic single table inheritance and force people to declare it explicitly. There are two reasons for this: 1. Implicitly doing it unnecessarially limits your use of inheritance where you really need it: in your object-oriented
