similar to: Division not working!?!??

I''m basically a Ruby noobie. At the moment I''m having a fair bit of trouble trying to figure out what''s going wrong here (partial template): <%= @project = Project.find(@the_id) if current_user.userid == @project.client hidden_field ''messages'', ''recipient'', ''value'' => @project.project_manager

Hey all, In my code, it seems that when I divide two integers, the result is an integer. Is there any way to make it such that when I divide two integers, the result is a double?

Hi, I am trying to read a series of stock tickers into R, and I'm running into trouble with Ford (F) and the old AT&T (T). Read.table seems to interpret these as boolean values instead of strings, even when I set colColumns to a vector of character(0)'s. Is there a way to convince it to read them as strings? Thanks in advance for the help, David

I can''t for the life of me figure this out. Been banging my head on this since the weekend, and can''t see what I''m doing wrong. This code works: image.resize("640x480") image.write(path) I run this and I get the resized file just fine. This doesnt work at all: width = 200 height = 100 dimensions = "#{width}x#{height}"

Hello-- There must be a better way to do this. I have a class method in my model that finds averages and does a few calculations using find_by_sql. The problem I¹m encountering is that all computed columns from MySQL come back as type string. E.g., def self.find_averages(domain_id) if @@domain_average return @@domain_average else @@domain_average =

Hello everyone! I''ve noticed, that the book uses double quotes almost everywhere. It is like <%= javascript_include_tag "prototype" %> I''ve checked the "programming ruby, 2ed" book and found that double quotes are most suited when escape sequences and substitutions are required. Isn''t it more semantically correct to write this code like

Hi, Is there an easy way of querying an active record for a maximum column value? I need to do queries like: SELECT MAX(salary) FROM employees TIA, Jeroen

Hi all - To avoid floating point issues, I''ve decided to store monetary values in cents in the database. However, the user will enter these in dollars and cents. Two questions: 1) How do I do the validation for the currency format? It looks like ActiveRecord truncates the cents since it thinks the field type is a Fixnum. Am I forced to do validation in the controller? 2) Where

I''m stuck in a catch-22 type problem. I have an insert form for a table that uses the validation in the model. i.e. When you click submit on the form and haven''t filled in the required fields then you get the nice rails error messages saying "field can not be blank". This works fine until I introduce some more logic. What I''m trying to do is to validate

Hi i''m using ferret to enable geographical postcode.

Hey Guys, Again, I am just learning Rails, so I am asking advice here. I have a model called Company which has many Owners. The Owners model indicates the name of the owner and their share (as a percentage) of the company. The total shares for any one company can not be more than 100%. So if I have 10 owners each with 10% of the company and I update one of the owners and set their share to 11%,

Easy one: Let''s say I have a table called ''employees'' with a column called salaries, how can I add Employee.salaries_total to the model? Thanks! -- Posted via http://www.ruby-forum.com/.

Hi all, I just noticed that in ActiveRecord::ConnectionAdapters::Column.type_cast[1] (and type_cast_code[2]) the type casting for float columns simply does value.to_f, whereas all the others have a rescue or call out to a method, the default implementations of which have rescues or enough logic in that I don''t think they''d fail. Imagine the following: create_table :vehicle do

Hi, Just thought it was weird that Ruby doesn''t automatically cast ints to floats. Seems so un-rubyish irb(main):006:0> 12/16 => 0 irb(main):007:0> 12.to_f / 16.to_f => 0.75 Jeroen
