similar to: has_one without inverse belongs_to

This bit of code finds several groups; all those which have entity_id''s of ''1'' OR ''2'' OR ''3'', as you would expect: ee = [ 1, 2, 3 ] groups = Group.find(:all, :conditions => "entity_id in (" + ee.join (",") + ")") But this bit of code only finds groups which have entity_id''s of

When I''m executing cucumber tests, I noticed that sometimes rails app (in test env.) getting several the same requests (GET or POST) usually around 3, and it doesn''t render anything with empty HTTP status code. Have anyone met something similar to that issue? here is some example of log file: Started POST "/account" for 127.0.0.1 at 2010-11-30 22:34:17 +0200

Hi all, I just finally figured out how to get 2.2.2 to do this, and thought I''d share in case others run into the same thing. The situation is a find with associations, but the tricky part is that the association shouldn''t always be loaded. This is similar to putting a condition on a has_many association in a model, but the condition is dynamic rather than predefined. The

Hi: I''m trying to manually append objects to an instance variable that is just an array of objects. Here''s my controller code: @tasks = Task.find(:all, :conditions => "entity_id = #{session[:user].id}") for t in @tasks if Subtasks.find(:first, :conditions => "child_id = #{t.id}") != nil @mtasks << t end end However, when I execute, I

i have a Project model, which belongs_to :user when i add a project, the users_id is based on the session[:users_id]. to get the users_id into the projects table, i''m doing this: @project = Project.new(params[:project]) @project.users_id = session[:users_id] this is working, i''m just verifying this is the best way to do it.

hey, i my database i have users and groups, each user can get in different groups my db structure: table groups: id, name, basegroup, firm_id table users: id, firstname, lastname, email table groups_users: group_id, user_id my relation is a many to many: class Group < ActiveRecord::Base has_and_belongs_to_many :users end class User < ActiveRecord::Base has_and_belongs_to_many

Hi, I''ve started reading some Java books. Gasp! What makes website development with Java so bad? I haven''t looked at Struts but I''m reading about Hibernate. Compared to ActiveRecord, Hibernate seems like some extra typing to explicitly define the model fields, getters and setters. I know that these are things that you can do in ActiveRecord when things get complicated

Hello forum! As the subject indicates, I am trying to make a barplot and would like my column names to be in bold. Is this possible in R without having to make my column names in mtext? Any help would be much appreciated. The code I am using is as follows. par(mar=c(3,8,2,2)) par(adj=.5) par(font=2) par(oma=c(3,3,3,3)) par(xpd=TRUE) Blot<-matrix(c(25.2995, 0.7625, 25.6135, 36.5770,

I have a problem with the :include option in find for my has_one :through association. I have Users, Profiles and Customers, all connected to each other with a has_one :through => :membership association like this: class Profile < ActiveRecord::Base #could also be user or customer has_one :membership # i saw an acrticle of Ryan about has_one :through, there this would be has_many, is

I''ve been using this sort helper to have sortable tables. http://wiki.rubyonrails.com/rails/pages/Sort+Helper I''ve encountered a situation where I need to sort a column that is not part of a table, but it''s related table. For example, say I have db tables called foos and bars. Foos have fields called name and title. And bars have fields called note and foo_id. Foos

I have two models (Car and Driver) and a combobox to select which driver belongs to which car. I want the combobox just show the objects that have not yet been associated. # vehicle belongs_to: driver # driver has_one: vehicle # simple_form # vehicle/_form.html.haml = f.association: driver, label_method: :name, value_method: :id How to ensure validation before saving, to avoid problems of

How can I save two models that have has_one and belongs_to relationship to each other? I want to save both the models by using script/console.

Hi. My model data is the following: - Place - User - Checkin Instead of having a Checkin that belongs to both User and Place, I chose to add another model, Program, that allows to list all the places a user can checkin into, and also hide the checkins he''s no longer involved in (= the user sign out of a specific program). That give me crazy relationships: Program has_many Checkin

So, I have 2 models A and B that share 5 common attributes and all other attributes are different. So I wanted to extract these 5 out into one common table and use has_one, belongs_to to knit it back together. So now there are 3 tables with 1 having the shared properties, we''ll call this table C. Table A id dollar_amount Table B id quantity_on_hand Table C id version My question is,

Hi All, Probably this has been asked numerous times, I apologize already! Can somebody point me to a good tutorial on how Rails works with relations? I know about database design and normalization, I also know about programming in general (and OOP for that matter). Only thing I can say is that I''m following the "Four days on Rails" tutorial by John McCreesh. He writes

Let me preface by saying i''m a total noob at ruby/rails. :-) For some reason, I am just not grasping the concept of has_one & belongs_to... I''m working on a project that includes user authentication, and 3 different types of user profiles. User profiles are either "fan", "band", or "venue" objects, and user logins are "user"

I have two objects, QuoteInput and Insured. QuoteInput has one Insured and Insured belongs to QuoteInput. I don''t understand what I''m seeing. I assign an Insured to a QuoteInput. The Insured object has invalid data. I call save! on the quote input. QuoteInput has no validations. I expect two things to happen - 1) an exception should be thrown, indicating that there was a

With a has_one/belongs_to relationship, what''s the best way to guarantee that the belongs_to object gets created and is accessible alongside the has_one object? I *think* the after_create callback is a good choice, but I discovered an oddity while trying it. F''rinstance, if every horse has a carriage: ============ ActiveRecord::Schema.define do create_table(:horses) {|t|

There really doesn''t seem to be a *declarative* way to define a default value for belongs_to and has_one associations class Person < ActiveRecord::Base belongs_to :address end p = Person.new p.address.city = ''Atlantis'' # Bummer! Of course, there''s an easy way to avoid this class Person < ActiveRecord::Base belongs_to :address
