In the Agile Rails book, on page 232 (PDF, 4th edition) there is an example of (within ActiveRecord) marking an article as read by a user at the present time. Short example code (from the book) here: class User < ActiveRecord::Base has_and_belongs_to_many :articles def read_article(article) articles.push_with_attributes(article, :read_at => Time.now) end # ... end

Hello All, I am new to ROR, and can''t seem to get HABTM to cooperate entirely... however I might be abusing it! Before I try a different strategy I thought I''d ask here and see if I''m missing something simple. So say Projects and Companies are related. Projects can have multiple Companies, and Companies can be on multiple Projects. But, the same Company can also

I''ve got some of this working but other parts are ellusive. I have CREATE TABLE `bags` ( `id` int(11) NOT NULL auto_increment, `name` varchar(255) NOT NULL default '''', PRIMARY KEY (`id`) CREATE TABLE `packages` ( `id` int(255) NOT NULL auto_increment, `name` varchar(255) NOT NULL default '''', PRIMARY KEY (`id`) CREATE TABLE

Hello there, this is probably a very simple problem but I''m stuck. I''m following the Login generator tutorial from rubyonrails. It''s all worked fine so far. But I want to add a bit more functionality so that when a user signs up in addition to chosing a login name and password they type in a company name which is added to a seperate table called COMPANIES. The id

Hello- I have a database with entries that are segmented by customers. I would like to be able to store / delete / restore a particular customer''s information. I will need to rebuild the rows on restore and also rebuild the associations for the different tables. For example, customer { id name } companies { id customer_id (belongs_to) name } contacts { id

Rails dies when I try to call a method from my Mailer. But I have defined my method. What could I have missed? Here is the irb session: >> p = Person.find(1) => Person data... >> SiteMailer.request_admin_approval(p) NoMethodError: undefined method `request_admin_approval'' for SiteMailer:Class >> SiteMailer.method_defined? :request_admin_approval => true The

Ok, this is a hard one and I just thought I''d see if people on the list had any suggestions on how they would approach this, I''ve not started to implement the rails to handle this yet as I''m still at the paper planning phase. I''m building an app that has to handle availability for travel packages. The complexity comes in that a person can choose a start

I''m trying to do, what seems like, a very basic join. However, the association just doesn''t seem to work. I''m sure it''s something very simple but I don''t know what. class Role < ActiveRecord::Base belongs_to :packages belongs_to :users end class Package < ActiveRecord::Base has_many :roles has_many :users, :through => :roles end

This SystemStackError is driving me crazy. It only takes place when testing with WEBrick - I can''t reproduce it with any tests. It is caused by calling the "missing" id method (base.rb:2435) on my ActiveRecord class. WEBrick and my tests are running as the same user, with a `ulimit -s` of 10240. Plus the query works sometimes so I don''t think this matters.

I am getting html output in my email body with spurious characters that cannot be rendered, so that my links are not handled properly. What am I not getting here?

I am building an invoicing system but cannot use the auto_increment field to determine the invoice number (because they are running 3 different companies off the one system. I need to find the last invoice number from any given company and then add 1 to it to get the next invoice number. BUT, there is a unique case on the very first invoice produced because there is no earlier invoice

Hi, I''m trying to figure the most efficient way to model the following. I can think of at least two ways to relate the tables but from a client/server perspective! I''m wondering how to best (and elegantly)relate them from an AR perspective. A project has many people, A person can work on many projects at any time, A project has many roles, A role is performed by a person, A

Hello *Gem* experts, Sorry for asking multiple questions in one post but they are both related to one problem. So far I have the following code: class Member < ActiveRecord::Base has_and_belongs_to_many :blogs, :uniq=>true ..... end class Blog < ActiveRecord::Base has_and_belongs_to_many :members, :uniq=>true ... end The issue is that

For a while, I''ve been getting that HMT is replacing HABTM. It appears that HMT can do all of what HABTM can do and more. The question is: Should I stop using HABTM? Let''s take a simple case: A case has many categories For a given category, there are certain valid statuses Category has_and_belongs_to_many :statuses Status has_and_belongs_to_many :categories Question: Is

Hi, I have 3 tables with HABTM relation. USERS -> QUOTE_TO_USER <- QUOTES Table QUOTE_TO_USER has 3 attributes: quote_id, user_id, component. I have a form where I can tie multiple users to QUOTE. This is easy one, thru "user_ids" (@quote[:user_ids] = @params[:quote][:user_ids]). In this form I have all users and I just check those I want to tie to this quote, however

This is probably a very stupid error on my side, but I am doing my first steps now and I don''t see what is wrong. I have companies and I have users. A user can create a company. When the user does he''s automatically a member of the company. A company should be able to have multiple users off course so every member of a company can add other users who don''t have a
