Hi, I am working thru the Ruby for rails book. On page 30 David Black talks about running erb from the command line i.e. $ erb erbdemo.rb just as you would a normal ruby prog ($ ruby erbdemo.rb) but when I try to do this I get command not found. How do I make this work? I am running Linux (Ubuntu Breezy) Regards, Paul

I have a loop that I iterate through in my view. <% coll.each do |itm| puts(itm.value) end %> How do I render the itm.value without using a <%= %> tag? Should puts not work? Joerg P.S. There is a good enough reason for me wanting to do this :-) -- Posted via http://www.ruby-forum.com/.

hello. first things first - I am new to ruby on rails (ruby, too), so I''m figuring this is just a basic newbie error. I''m creating a basic photography website. And I have two tables with a relationship: photos: - id (set up as PK) - title - shutter - aperture - date - the_order ...etc photo_comments: - id (set up as a PK) - photos_id (set up as a FK) - author - date -

I''m having a problem getting this example from the book to work: class Cookbook attr_accessor :title, :author def initialize @recipes = [] end def method_missing(m, *args, &block) @recipes.send(m, *args, &block) end end cb = Cookbook.new cb << recipe_for_cake cb << recipe_for_chicken beef_dishes = cb.find_all {|recipes| recipe.main_ingredient ==

I''m using Rails-1.1.4 with Ruby-1.8.4 So let''s say I have 2 model classes: class Item has_and_belongs_to_many :things end class Thing has_and_belongs_to_many :items end i = Item.new i.things << Thing.new( :value => "Something").save i.things << Thing.new( :value => "Something Else" ).save i.save Fine, now I have two records in the

I''m trying to figure out an elegant way to do this: I have the following three tables: people, employer, employees And consequently the following three models: class Person < ActiveRecord::Base end class Employer < ActiveRecord::Base has_many :employees end class Employee < ActiveRecord::Base belongs_to :person belongs_to :employer end I want to be able to say:

I have a users table. I have a assignment table. and I have to log in to see my assignments. i can and I hasve a session id. I can make a new assignment and save my id in the user_id field of the assigment table. I want to share my assignments. so I can create a assignments_users table. this way I can have assignment 1 shared with user 1 and 2. and If I log in as user 1 or 2 I see the assignment.

Hi, I have a class called Outlet which has_many Jacks. Apart from internal id, each jack is unique by the attribute ''color''. I''d like to iterate through each Outlet, and be able to output data for a Jack of a certain color. Say, I want to access the orange jack for the current outlet: <td><%=h outlet.jack.color[''O''].ip_address

This may be a more generic Ruby question, so I''m going to ask on the Ruby forum, but I''m trying to figure out if there is a way to pass in the string value of a variable as the name of a method. For example, I would like to do something like: def sort_obj_by_uid(objects,@attr) @tmparray = Array.new @tmphash = Hash.new for object in @objects if !

Hi all. Got a stupid-simple question about associations. I have two models - school and course. There are a fixed number of schools (set up in the migration). Each course is assigned a school and a school will be associated with multiple courses... How do I set up the associations? Do (can) I have School :has_one :course and Course :has_many :schools? Does the schools table then get a course_id

hello, On page 49 of the beta version of Ruby on Rails: Up and Running, the book suggests to download a zip file containing everything that has been done up to that point, and a create_tables_with_data.sql file. The book doesn''t have the link, and I couldn''t find it in the book site. Does anyone know where to get the files? This is a very good book. Thanks. -- Posted via

Can I set an application wide instance variable that is available for all actions...and their views? eg. class ApplicationController < ActionController::Base @current_user = User.find(session[:user_id]) end and everywhere I can call @current_user.id and I can get that object? Even down in the views? I could not get this to work... Thanks in advance, Jeff -------------- next part
