This may be more of a Ruby question, but I wasn''t sure. Is there a way to run a find on a model and then save two fields as key => value in an array for each row. Then use this array on the template for checking if various checkbox or select values are checked? I''m trying to avoid running one query to check the value for each box in the form. - Kyle

I'm interested in using a data frame as if it were a hash table. For instance if I had the following, > (d <- data.frame(key=seq(0.5, 3, 0.5), value=rnorm(6))) key value 1 0.5 -1.118665122 2 1.0 0.465122921 3 1.5 -0.529239211 4 2.0 -0.147324638 5 2.5 -1.531503795 6 3.0 -0.002720434 Then I'd like to be able to quickly retrieve the "value" of "key" 1.5

Seth, It really depends how often you do that check. If it happens only once or twice in your whole application, that''s just fine. If it happens more than that and in multiple controllers/views then maybe you want to create a helper for it. Something like this: (didn''t test it, but should be working) module ApplicationHelper def current_id_select(controller, action) (

When using link_to_remote, I''d like to pass along some auxiliary data in the request. It''s a hash of dynamic data that can change with each request. But I get an error when rails trying to "stringify" the hash. For the regular link_to, it works because it turns the hash into a regular GET-like query string. I''m expecting to be able to get my hash as

Hello, I'm looking for a good way to apply a custom hash to passwords.? My hope is to add passwords to a (MySQL) database: INSERT INTO users (user='joblo', pass=MYHASH('plain-password').. For SASL authentication, my thought first was to apply the same hash to the issued password and compare it with the hashed password in the database.? I soon discovered the sql driver

I just started playing with rails this week and am working on porting our existing website to rails in our navigation we have a list that has the days of the week that link to the articles for those days. this seems to be working when I had it in the template it would give me the array I was looking for so I decided to move it to the helper so that I could use it on all my templates.

Because here in Puppet-land we''re all about self-reference and recursion, and because I actually have to give a talk at RubyConf next weekend about abusing self-reference, and because parent nodes aren''t considered harmful in my own world, I give you: http://www.codinghorror.com/blog/archives/000982.html I think it manages to somehow be both on- and off-topic at the same
