similar to: has_many and belongs_to example?

I have two tables: class PgmUpdate < ActiveRecord::Base has_many :pgm_visits, :foreign_key => ''pgm_update_fk'' ... and class PgmVisit < ActiveRecord::Base belongs_to :pgm_update, :foreign_key => ''pgm_update_fk'', :dependent => true ... According to the has_many docs (http://api.rubyonrails.org/classes/

class PgmUpdate < ActiveRecord::Base has_many :pgm_visits ... class PgmVisit < ActiveRecord::Base belongs_to :pgm_update ... I am trying to make sure that none of the visits in PgmUpdate overlap start and end dates. Should this validation exist in PgmUpdate or the controller? It seems natural to put them in PgmUpdate, but I must force the relationship together because

Hi, I am pulling my hair out trying to work out how to put together what should be a simple app in rails. The app is to CV''s so I have a table of CV''s and each CV can have multiple skills. Skills are in a 2nd table below; CREATE TABLE cvs( id INT not null AUTO_INCREMENT PRIMARY KEY, first_name VARCHAR(30) not null, family_name VARCHAR(30) not null, email

Hi all, How does this look as a general approach to a SID.create method: # Creates and initializes def self.create(authority, *sub_authorities) if sub_authorities.length > 8 raise ArgumentError, ''maximum of 8 subauthorities allowed'' end authorities = Array.new(8, 0) authorities.replace(sub_authorities) count = authorities.select{ |e| e > 0 }.size

I am populating a table skills which relate to a table cv in a 1 cv to many skills relationship... I populate the skills as below; def new @session[:cv_id] = params[:id] @skill = Skill.new end def create @cv = Cv.find(@session[:cv_id]) @cv.skills << Skill.new(params[:skill]) if @cv.save flash[:notice] = ''Skill was successfully created.''

Hello all, I''ve come up w/ a worker class that manages queued jobs using a fixed number of child workers. Well, that''s not quite true -- a new worker is spawned for each job, but you set the total number that may exist at once. There are three components: 1) queue_worker.rb: The singleton worker that manages the child workers. You probably want to auto start this. Make sure you

Disclaimer: Ruby newbie at work Thought I was going so well. Wanted to produce a select box from an array constant, with the indices returned as values , and the array values used as the descriptions. Checked out Ruby RDoc and saw there was an each_with_index method and came up with: <%= select (''type'', ''typecategory'', Typecategory.each_with_index

Okay, I know this will probably be a very easy question. But I am discovering that RonR makes just about everything easy. The problem is, it takes me a few hours to figure out that I can do it the easy way. I need to know how to move to the next record in a database. I want to format my out put in a table. For example, I want a 3 by 3 table. So record one goes in the first cell, record

I''m trying to figure out how to design a view and controller to work with a simple collection. I have a Foo that has many Bars, so here''s what I did: $ ruby script/generate model Foo $ ruby script/generate model Bar (Uncomment t.column, :name: :string in foo and bar migrations) (Edit Foo.rb and Bar.rb, add has_many :bars to Foo, belongs_to :foo to Bar) $ rake db:migrate $ ruby

Team, I am trying to learn a GUI for Ruby and I picked wxRuby. The problem is that I am kind of slow learning this and I now feel frustrated after trying for about at least 7 hours. I am trying to design a simple Sudoku 9x9 grid to display numbers, 1 - 9, using buttons. I posted a question on Ruby forum ruby-talk and a gentleman, Alex Fenton, answered my questions. Alex gave me what appear to be

Hi, for my isbn plugin, I''m wishing to incldue generated isbn pages in caller pages (the ones with <isbn value=""> tags). But I want my isbn page to be processed before for its tags to be transformed (like the relocatable or other ones). Besides, i do not want its header to be included.

Dear R users, I have a problem in the configuration of R: I just changed university, and my conection to the net is via a password, which permits me to access the packages with no problem via the internet explorer (version 6). I just updated R to R 1.81, and I cannot download nether upgrade packages (and many are not working with the update!!!). I have been looking in the help and emails, and

Hello, I'm fairly new to Linux and I like it a lot. Unfortunately some of my favorite applications are Windows based, so I started looking into Wine. I don't have a Windows installation. I got a few 16 bit and 32 bit applications to work, but as soon as I try to set up an application that tries to write files into a folder with spaces, like 'Program Files', the destination

I have a need to subclass models a lot and I thought modules would be the way to go, but I am encountering nothing but trouble with them. I seem to be getting stuck with storing an object in the session, but on the next request it can no longer read the session data and creates a new session. Any other time I use the model it works just fine. I read "Agile Web Development With

Hi, [reposting to list, posting via google groups apparently didn''t work] I''m trying to use acts_as_list for the first time. Can anyone confirm the odd behaviour reported here? http://blog.nominet.org.uk/tech/Web/2006/03/06/Using_acts_as_list_in_... i.e. element access and move_higher require an odd indexing scheme to work. I''m personally finding that I

So I''m having some problems with some of my manifests that I''ve been using for a while and I''m not entirely certain what''s going on. What appears to be happening is that puppet when it runs can''t see the value for one of the default facter facts (domain). I''m not real certain that this is the actual problem I think this is just how
