Hi folks, Thanks to the community feedback on the 1st version, I''ve come up with a much improved version of the acts_as_taggable mixin. There´s some piece of the action here: http://dema.ruby.com.br/articles/2005/09/03/tagging-on-steroids-with-rails Cheers Dema -- http://dema.ruby.com.br - Rails from a .NET perspective

There appear to be three acts_as_taggable implementations and I''m looking for a recommendation on which to use. - Gem - DHH plugin - Dema mixin The Gem implementation appears to be obsolescent, from what I can read on the lists and Google search. I like that the DHH plugin uses polymorphic associations because there will be lots of different taggable items in my application; however, adding and removing tags is a bolt-on, not desig...

I was testing my models with this new library and I got: >> s.tag "warp" ActiveRecord::StatementInvalid: ERROR: inserción o actualización en la tabla «tags_stories» viola la llave foránea «tags_stories_story_id_fkey» DETAIL: La llave (story_id)=(8) no está presente en la tabla «stories». : INSERT INTO tags_stories ("tag_id", "story_id") VALUES

This is a weird one: My app works fine on our local box with webrick. After uploading to TxD server, the app starts behaving weirdly. I make some edits to one of the controllers and my changes don''t seem to be going through. So I go ahead and change the name of the controller file. The page loads without error. I figure maybe I''m in the wrong directory, so I change the

...ruby and rails under windows(exactly this one: http://rubyforge.org/frs/download.php/4174/ruby182-15.exe that includes rubygems) the thing is that while trying to install the mysql gem, it seemd to try to build the native extension, so I finally added a compiled version that I found in http://dema.ruby.com.br/ the problem is that webrick behaves quite unstable while querying to the database and makes it to close too often. is anyone suffering this too? any recomendation? thanks in advance

...hown in the diagram. These spikes do not have more than one or two points. I consider larger groups as relevant and want to keep them in. I sometimes have less than 5 points for each step, and up to 50 at max. Given these conditions would you suggest using one of the moving averages (e.g. SMA, EMA, DEMA, ...) or the locally linear regression (lowress) method. Are there any other options? Does anybody know a good site that overviews all methods without going to much into mathematical details but rather focusing on the requirements and underlying assumptions of each method? Is there perhaps even a p...

...lp-es, Estoy interesado en estimar una curva dosis-respuesta para un conjunto de datos y para ello, estoy utilizando la libreria "drm". Hasta ahi todo bien. Me gustaria automatizar algunas cosas y el primer paso para ello es la estimacion del modelo. Si la estimacion funciona, todo lo demas funciona; de lo contrario, todo fallara. Tengo algunas lineas que mitigan un poco el problema, pero no cuando hay problemas de convergencia como el que se ilustra a continuacion: # datos d <- structure(list(y = c(509.75, 498.8629, 584.9069, 808.5421, 679.3904, 597.3327, 561.4653, 496.4428, 47...

Hi, I began experimenting with habtm relationships, and so I created a stories table, a tags table, and a stories_tags table referencing the former 2. When I create a "story", I want to add several tags to it. Then, the model should create those tags and link them to the respective stories, and for the tags that already exists, just link them to the story. I tried something like

Googling for acts_as_taggable is a little confusing: gem, plugin?! What are the differences? Which one to choose? Where is the best doc? Alain

Hola Jose, si CONCATENAR significa APILAR, es decir, concantenar verticalmente, por decirlo de algun modo, podrias hacerlo con rbind(): nuevovector <- rbind(vector1,vector2) Si ademas quieres que cada valor de los vectores originales sea identificado en el nuevovector, puedes usar: nuevovector <- stack(vector1,vector2) en este ultimo caso se agrega una columna adicional tipo factor, con el nombre de la columna de los vectores originales. lo demas no lo entiendo :) ojala...
