Thanks for the reply, Mick. I do the have the database connection params set correctly in config/database.yml. I stumbled across the following post (http://www.elharo.com/blog/category/software- development/databases/), and the suggestion was to change the mysql version from 64-bit to 32-bit (the mysql.com downloads). I did, and it works as expected now. As the mysql gem is compiled

Hi all, I wonder if it is somehow possible to execture or redirect to a controller function from RJS? Right now I do: def foo() render :partial => ''executeagain'' end _executeagain.rhtml <script> new Ajax.Updater(''elmntID'', ''/test/foo/'', {evalScripts:true}); </script> This will loop I know :) How can I achieve the same

In java/c++ the method signature provide a good details on which parameters the method accept, but in rails the ability to send hash as parameters make it impossible to know which parameters can be send. This ability make the rails API doc a must to be full of details and not supply partial examples of usage. When for example I see *link_to_remote*(name, options = {}, html_options = {}) I would

Hey all, Ok this is probably a newb question, but I haven''t been programming with MVC for very long, and I''ve been wondering what the general opinion is, or best practices, for making a new controller. Like what cases would you need a new controller for and what cases can you just put everything into one controller? Thanks in advance, Randal -- Posted via

In the initial version of my application I am just going to require cookies - down the road _considering_ changing that and providing something that works without. Anyway, this is somewhat of a two part question 1. Does this approach make sense or is there a better way typically used? Just have a before_filter in my application.rb to verify that the :_session_id cookie is present. If it

Is the mechanism by which packages are tested on CRAN described anywhere? Is it by any chance written in R?

Hola, ¿qué tal? Cierto, cierto, había un error en el código que publiqué. Pero el diagnóstico es parecido. Cuando los datos se generan con el coeficiente de x2 igual a 7, los coeficientes estimados tienen una distribución extraña, bimodal (aparentemente), en lugar de _normalmente_ distribuida alrededor del 7 como se espera. Supongo que depende del número de casos en que x2 = 1 e y = 0. Un

Hola, Deseo simular un modelo logit con interacción, estimar sus coeficientes y comprobar si son o no parecidos al modelo teórico.
