In my application model I have three classes: Accounts, Projects, and Items class Accounts < ActiveRecord::Base has_many :items, :through => :projects, :source => :items has_many :late_items, :class_name => ''Item'', :through => :projects, :conditions => [''due_on < ?'', Time.now], :source => :items end class Projects <

Hello again, I have a table called line_items, with the following fields: id int item_name varchar() qty int conditions text I''ve made my LineItem model, and everything works as such (with simple text_fields).. Now I''d like for the conditions field to be a select_tag() with multiple choice possibility. I''m guessing I need some code to expand/restract the array for

Dear list, I'm having trouble to see how my elements on a 4 dimensional array are listed. For example, I generated the following array: junk.melt=melt(occ.data,id.var=c("Especie", "Site", "Rep", "Año"), measure.var="Pres") y=cast(junk.melt, Site ~ Rep ~ Especie ~ Año) Now, I want to be able to look at how my species (Especie) are listed, in

What is the equivelant of the following SQL in rails: SELECT person, count(person) as occurance FROM invoice GROUP BY person; This would give something like: Person | Occurance -------------------- Bill 1 Joe 15 Carlos 7 etc etc.. It seems the fx. Person.count(..) will only yield the actual occurance, but not listed with the actual person - and Person.find(..) will not

Hello, I''ve got DB like this: (roughly) create table projects ( id int auto blabla, name varchar(200), user_id int, sales_id int); create table users ( id int auto.., name varchar(50)); So project.user_id has a foreign key to user.id - all is good. Everything works fine. Now my question.. How can set a relationship from two different fields to the users table ?? Fx.

List, I want to reshape my data, but I'm not sure how to do it... it might be a simple task, but don't know which package does this. "occ.data" (see below) is how my original data are arranged, and I know that with melt() I can reshape it like "y" (see below). However, I just want to build a matrix like the "y" matrix, but with only 2 dimensions. Something

Hi i am trying to figure out what is the best way to do this very basic thing: lets say i have two tables: one with parents and one with children. there is a one to many relation between them. I scaffolded the parents tabel and i can open each parent. Now i want to add a link to the ''show'' view which will create a new child record. In the model i defined the has_many and

Hello, I''m writing a search function for my application, but I am unsure on how to search for all results that contain my search string; here''s what I''ve got: def search @products = Product.find(:all, :conditions => "date_available < now()", :conditions => [ "title ilike ?",

Hello, I want to a select tag, where you can choose a number between 1 and 100. My inital code is based on the examples from Agile Web Development with Rails, and looks like this: view: <%= options = [["Select number of lines", ""]] + RfqLines::LINE_QTY select("rfq_line", "line_qty", options) %> model: LINE_QTY = select_fill def

So I''ve pretty much followed the steps in the video tutorial on RoR.com for creating a small app, to search for photos on flickr.com - all is good, and works as intended to.. How would I go about adding validation, so if no tags are specified it will fail. I know I have to use validates_presence_of :tags - but not in the controller.. so I tried to generate a model called

This was published on O'Reilly's site last week, but they didn't tell me until now. :) The article is pretty minimal, because I had a limited number of words to work with, so many features are not implemented. However, it's a good start. http://www.onlamp.com/pub/a/onlamp/2003/07/03/asterisk.html I had a few people review it beforehand, but I'd also welcome changes or

I am working on an Rails application that uses a pretty complex category structure through out the site. I have defined a table to house all the info and a FK to reference parents within the table CREATE TABLE categories ( id int(11) NOT NULL auto_increment, name varchar(50) NOT NULL, parent_id int(11) default NULL, constraint fk_category_id foreign key (category_id) references

As far as I can see, here is a summary of the situation, and there's a point to this, but I only make it in step (4), needing the first three steps to set up a background to keep my own thoughts clear: 1) Fedora (via Jakub) shows it's possible to patch OpenSSH. 2) OpenVPN (via gert) shows it's possible to build a 'shim' of sorts that allows code to work with libreSSL and

I am going nuts here.. I have a form where users can write a city name (used with auto_complete) - and once they click on the desired city in the dropdown menu - I would like to have the Country field filled automatically as well... Is this possible at all ? If so, can somebody please tell me where I can find some documentation on the subject, or preferrably an example ? Many thanks in

So, I hear that with_scope is going to be deprecated. Which is a bit of a shame, given the stuff I''ve been writing recently. I have a CMS with multiple clients. A ''client'' is essentially a company, with multiple users. Content on the site belongs to a client - content could be messages, images, schedules, etc etc. People belonging to one client should not be able

I just upgraded from v0.9.9 to v0.9.32 (on Ubuntu 6.06) and Eudora Pro v4.2 stopped working. It no longer opens a mailbox when the icon is clicked. The log shows "fixme:rpc:alloc_serverprotoseq protseq "mswmsg" not supported" each time I click to open a mailbox. This was working on v0.9.9 so I am looking for ideas as to how to work around this problem. There is a bug
