I have a Project that has_many Tasks. Tasks belongs to a Project. When I try the following: project = Project.new project.tasks.build I get: >> s = Project.new => #<Project:0x25f9e28 @attributes={"name"=>"", "end_at"=>nil, "updated_at"=>nil, "published_at"=>nil, "user_id"=>nil,

...9;ve used console to test my models and they all work ok, I can do manually what I''m trying to do with Rails. There is something in the code somewhere outside of the model code that is causing this problem and I''m at a loss to track it down. I''ve traced into the code for has_many_associations.rb: def insert_record(record, force = false, validate = true) set_belongs_to_association_for(record) force ? record.save! : record.save(validate) end and it blows up on the force ? record.save! : record.save(validate) line. Here is the stack trace: wrong numbe...

I am trying to do something right from Agile Web Dev with Rails book and it does not work. I must be missing something obvious. I have a one-to-many relationship: class Draft < ActiveRecord::Base has_many :endorsees end class Endorsees < ActiveRecord:: Base belongs_to :draft end >From my reading, methinks I should be able to say: d = Draft.new d.endorsees << Endorsee.new

I''m in the process of creating a sign up form for an online application. The form collects account info, company info, and then info for an administrative user. The method looks like this: def create @account = Account.create!(params[:account]) @company = @account.companies.create!(params[:company]) @user = @company.users.create!(params[:user]) end However, this inevitably fails

Without getting too deep into my app I''m wondering if anyone has any clues what might give rise to the error posted below. It occurs when I run my unit tests. class Actor < AR:Base belongs_to :court_case end class CaseCause < AR:Base belongs_to :court_case end class CourtCase < AR:Base has_many :actors has_many :case_causes ... end def my_test_method ...

Hi, This is just kindof a RoR question, but since you all potentially do the same things as I do, I thought I''ll ask here.. Im trying to use the boolean type in the database. Migrations is no problem, it even converts the 0/1 values from my import CSV to false and true. However, I cannot make the :conditions part of a find work: Loading development environment (Rails 2.0.2) >> c

I am dealing with a large project. I use a lot of STI and therfore have a lot of models. I''d like to use namespaces to help organize my models but am having trouble getting started. I have a base model Term::Base located in /app/models/term/base.rb: class Term::Base < ActiveRecord::Base set_table_name "terms" end I have a non-namespaced client model: class Client <

I''m getting the following error unexpectedly for my rails app. I just exported the databae from dreamhost and imported it on textdrive for my rails app. Mysql::Error: MySQL client ran out of memory: SELECT COUNT(*) FROM comments WHERE (comments.listing_id = 2666) /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.13.2/lib/active_record/connection_adapters/abstract_adapter.rb:88:in

[Sorry for the poor subject; this is really hard to explain] I''m trying to run a search over several objects which themselves contain multiple model objects, like so: class Collection << ActiveRecord::Base def findpkg self.repositories.each do |r| p = r.packages.find(:all, :conditions => "name like ''%pkg%''") end end end

For some reason rake spec is totally crapping out on me. I don''t know what I did to make it break, the only thing I tried new was install haml, but even after removing it there is still a stack trace. Here is what I am getting- sparta at phalanx ff $ rake spec (in /Users/sparta/Projects/work/idastudios/ff)

Hello All, I''ve run into a snag. (I apologize in advance. I''m not very good at system administration.) I''m building an app that allows users to upload files. Up until now I have been storing the files on the file system, but tonight I decided to change the app so the files are stored in the database as a longblob. I thought everything was working great, until I

has_many.count does not seem to support an options hash like ActiveRecord::Base.count does. Example: >> AcademicProgram.find(:first).course_requirements.count :conditions => "courses.name LIKE ''a%''", :include => :course => 40 >> ap.ap_requirements.count :conditions => "courses.name LIKE ''a%''", :include =>

So, I''ve written a partial that does some stuff with a given instance of my class "entity". Entity is ActiveRecord. I''m able to retrieve all sorts of data from an @entity, until I do something like: <% for @attribute in @entity.attributes %> <div id="attribute_<%= @attribute.id %>"> <%= render(:partial =>

I''ve been stumped on this for a few days and I''m not sure if it''s an error on my end or an actual bug. I have a system where I have workshops and users. Workshops have students, presenters, and troubleshooters. I wanted to represent this simply by using has_many :through with :source. Workshop has_many :presenters, :through =>:presenterships, :source=>:user

Hi, I have a strange problem that only occurs on the production server. I''ve been banging my head for hours trying to figure it out with no success. Below is a copy of the error from the production log. ActionView::TemplateError (Expected /www/rails_apps/scanlan/current/ public/../config/../app/models/image.rb to define Image) on line #6 of app/views/admin/design/_record.rhtml: 3:

I can submit a patch, but wanted to confirm I''m looking at this right... The docs indicate that if you specify a has_many association with :finder_sql, but no :counter_sql, it constructs the appropriate counter sql by substituting the SELECT clause. But has_many_association.rb doesn''t seem to do that -- it just passes Base#count_by_sql the finder_sql, which doesn''t

Hi, I am quite new to Ruby on Rails so this might have a very simple answer... My problem gives the following error message when I try to call the count function for an item. Mysql::Error: Unknown column ''TournamentTemplate'' in ''where clause'': SELECT count(*) AS count_all FROM action_logs WHERE (action_logs.loggable_id = 1 AND action_logs.loggable_type =

I seem to be missing something because I am at a loss on how to get rcov, RSpec, and Rails working together. Would someone mind dropping some hints?
