Hi, I''m trying to use counter caching in a tree structure (in this case Bob Silva''s threaded list). This is the definition: class Folder < ActiveRecord::Base acts_as_threaded has_many :files end I would like each parent to have the total count of all the childrens member. So when inserting a new file I update the file_count following the parent_id through all the

I''m creating a address book. A user can have many contacts. In the user model, I put: has_many :contacts And in the contact model, I put: belongs_to :user To list all contacts, I search as following: @user = User.find(session[:user_id]) And rendering: <%= render(:partial => "contact", :collection => @user.contacts)%> To persist I am using the following

So I''ve worked through Agile Web Development with Rails and I''m now trying my first little app to get into the swing of things. Its a task tracking app where people can create tasks and assign them to others, and also log time against the tasks. I''m having trouble working out the model relationships. This is what I''ve got so far, but its not right as

I''ve already pulled my object from the database. Now I want to add a method. What I''m doing is adding the username to the activerecord object so I''ll have the name and user_id. How can I do this. The code below fails in the view. It appears it''s overwriting the rest of my object def self.find_with_author(id) @article = Article.find(id)

Hi! I''m converting my Rails 3.1 app from cookie sessions to database sessions. I''ve added an extra column on the sessions table to save the user_id. I read the documentation in http://apidock.com/rails/v3.1.0/ActiveRecord/SessionStore and googled but can''t seem to find a way to set the session''s user_id that works. Can someone help?

I''ve got User has_one Shop. Rails is not validating when I tried create_shop or build_shop, neither in the browser nor the rails console. My code: class Shop < ActiveRecord::Base attr_protected :user_id belongs_to :user validates_presence_of :name, :primary_address, :city, :country_code, :currency end class ShopsController < ApplicationController before_filter

Looking for some guidance/support on what feels like might not be an uncommon use-case. `User.has_many accounts` `User.has_many payment_methods` `Account.belongs_to :user` `Account.belongs_to :payment_method` `PaymentMethod.has_many :accounts` There are lots of `Accounts`. When I (a `User`) want to assign accounts to a `PaymentMethod`, I really don''t want to scope against all of them,

Hi all, I have what I thought was quite a simple requirement but something to do with the way ActiveRecord''s associations work is making it quite puzzling. I guess I can sum it up with this failing test: before(:each) do @source_comment = @source.comments.create(:user_id => 1) @target_comment = @target.comments.create(:user_id => 1) end

Hello all, I''m having a strange issue with a model that belongs_to two other models. The one association is polymorphic and the other is normal. ================================ class Role < ActiveRecord::Base belongs_to :user belongs_to :permission, :polymorphic => true end class User < ActiveRecord::Base has_many :roles has_many :programs, :through => :roles end

Hey all, I''m not positive if this is a Engines bug, but it seems very peculiar and a few hours of Googling haven''t given me any good leads yet, so I thought I''d see if it makes sense to any of you: I am writing a new version of the savage_beast plugin (implements Beast forums as a plugin) that''s Rails 2.0 compatible, and I am having trouble with the many

All, Tuesday week (July 15th) Mike Driscoll & I will be presenting "A Gentle Introduction to R and its Applications in Business Intelligence" at the SDForum Business Intelligence SIG in Palo Alto, California. One motivation is to judge interest in starting a Use R Group in the Bay Area. We will have an informal organizational meeting after the talk. We hope all local R

Hello rspec-users, I''ve encountered a strange bug in rspec, but it may be me who is wrong. I''m running latest version from the trunk (r1678) of both rspec and rspec_on_rails. Please consider the following model: class Url < ActiveRecord::Base def after_save Contact.create!(:primary_email => ''user at example.com'') raise

Hi all I am new to Rails, and obviously I''m missing something, I''ll get straight to the question: A User has many operations (granted to her), each Operation is associated with an OperationType. Each Operation may be associated with more then one User. So the model goes like this: class User < ActiveRecord::Base has_and_belongs_to_many :operations

Hi I''m trying to understand the AR find facilities, described here: http://api.rubyonrails.com/classes/ActiveRecord/Base.html#M000650 I have a list of ids that I want to retrieve, but have a condition that should restrict the list returned: return self.find( noteids, :conditions => [ "(private = 0 OR (private = 1 AND user_id = ?))", userid] ) According to the

Search doesn''t seem to be working, so forgive me if I''m covering old ground here, but I''m having a difficult time figuring out how to implement a "SUM()" function using Active record. Obviously, I could just create a query, but I''d rather make it part of my active record object. Basically I have an object called "Report <

I''m using zentest and the test::rails class to do my controller testing, and the following line in my controller throws an error: session.model.user_id = user.id It looks like session is just a hash when testing, which would be well and good except that now I have to write if session.respond_to?(:model) session.model.user_id = user.id end which doesn''t feel right to me

Hi folks, Im trying to use an xmlrpc server and have it serve data using activerecord, but every request seems to eat up a mysql database connection, until I run out with "Too many connections". I don''t know enough ruby/rails (or rather ActiveRecord) to figure this one out. > ruby -v ruby 1.8.4 (2005-12-24) [i686-linux] > rails -v Rails 1.0.0 code below: Here is some

I cannot find this anywhere, and it is holding up a project. I have a *very* simple rails app with three tables, one of which is the users table: users: Column | Type | Modifiers ---------------+-----------------------------+----------------- id | integer | not null default nextval(''public.users_id_seq''::text) login

Does anyone know if it is possible to perform an ActiveRecord find by passing in an array? I would like to be able to do the following: MyModel.find(:all, :conditions => ["user_id in (?)", users]) The problem I run into is that the returned SQL contains the to_s() output of the User object, not the ids of those users. Is it possible to change this behavior? I attempted to
