Even though it''s a little OT, I thought I''d announce the free public beta of a new Rails app that I''ve been working on for a while: http://9cays.com Think of it as mini-mailing list software. For a lot of smallish conversations, normal mailing list are too heavyweight (requiring setup, moderation, admin, etc.), but group email is a pain because messages

Victor, Me parece que podrías investigar si Scribus puede generar e insertar la salida de R en sus documentos, por lo que estás agregando a tu pregunta me parece que BI no es el camino. Si lo haces, creo que a más de uno en esta lista le interesará la experiencia. La alternativa sugerida por Emilio usando Rthml y CSS con probablemente markdown y, yo agregaría, pandoc me resulta muy interesante y

Hi all, I have a has_many relationship, Cookbook :has_many Recipes If I want to create a new recipe in my cookbook I do: cookbook.recipes.create(data) It would be nice if I could then easily get the id of the new recipe, but the create() method doesn''t seem to return anything.

I''m having some trouble with an instance variable being read as nil in my app. I have an image uploading, that can be added to categories. The page loads up initially fine, and if I upload an image without errors everything works fine. I''m working on the validation, but with the code I have if their are validation errors it renders ''new'' again, but reads

One more question: Is there some way to set the human_name of a column? e.g.: human_name for column address1 shouldn''t be Address1 but "Address, line 1". If not, should I make a hash with my custom names?

Hi, I''ve noticed that my remote_function calls are resulting in POST requests. As a result, my routes do not apply since it does not generate a url based on the parameters, but simply posts to the raw url with post data. I want to make a GET request instead of a POST. How can I do that? Has anyone else run into this? Thanks, Ryan -- View this message in context:

I need to use UTF-8 in my app and was wondering if Rails would support it properly. Some sites seem to be saying that it has weak internationalization support. Is this true? If so, where is the problem? What should I look out for? Are there tweaks, plugins or gems that fix the problem? TIA. David -- Posted via http://www.ruby-forum.com/.

Hola lista: Una duda rápida (espero). ¿Se puede hacer un "inlcude" o un "input" en markdown? sin emplear Rmarkdown o knitr.... solo puro markdown, de modo que por ejemplo github lo interprete o un visor básico de markdown. la idea es q un file muestre(contenga) todo pero tener la info distribuida en varios files.

Buenas! Supongo que será fácil, pero se me está haciendo difícil. Tengo un documento Rmarkdown en RStudio en el que escribí lo que me pidieron, que me lo piden en formato MS Word. Markdown lo saca decentemente, pero me temo que no tan decente del todo las imágenes. Quiero que, además de salir las imágenes incrustadas en los respectivos chunks, también salve automáticamente la imágen en archivos a

I create a simple engine with a simple controller: class FredController < ApplicationController def hello render :text => ''Hello, world!'' end end and I create a simple functional test within the engine: class FredControllerTest < Test::Unit::TestCase ... def test_hello get :hello assert_response :success end

Ese es en particular uno de mis miedos. Aunque soy de la idea que todo conocimiento sirve, no ando con demasiado tiempo para ir probando. Capaz que la pregunta debió ser cual de los dos (o más, puesto que no se si existen otros) creen que seguirá un buen desarrollo futuro, no sea cosa de invertir mucho en alguna cosa que luego al final cuando ya le coja la mano tenga que migrar para otra...
