Hi all, I''m messing around with has_many, and has_many :through (on edge rails), using a join model. Branches and Projects join through ProjectsAtBranches. If I do @branch.projects, I can see the associated projects, and visa-versa, if I manually put them in the join table. But I cannot do @branch.projects << Branch.find(blah), or @branch.projects.clear, and then save the

Is there some sort of good pattern for dealing with computed values with Rails/ActiveRecord? A simple example: 3 tables, classes, students, and student_class_records (habtm style relation but contains a good deal of additional state so is modeled explicitly) Something like select the 10 classes with the most students. Easy enough in SQL. So I''m using a lot of find_by_sql and

I have two models with an habtm relationship: Foo has_and_belongs_to_many Bars (and vice-versa, obviously). Let''s say Bar has_many Bazs (how the heck do you pluralize Baz?). It would be nice to be able to say that Foo has_many Bazs through => Bar, but this does not seem to work. Am I right, or should it be possible to do this? The best I have been able to do is this: bazs =

First the data model: class Forum < ActiveRecord::Base has_many :topics, :dependent => :destroy, :order => ''created_at desc'' end class User < ActiveRecord::Base has_many :topics, :dependent => :destroy has_many :comments, :dependent => :destroy has_many :replies, :dependent => :destroy end class Topic < ActiveRecord::Base belongs_to

Hi I have a timeSeries object (X) with monthly returns. I want to display the returns with a barplot, which I can fix easily. But my problem is labaling the x-axis, if I use the positions from the timeseries It gets very messy. I have tried rotating and changing the font size but it doesn't do the trick. I think the optimal solution for my purpose is too only display every second or third

Chris, Finally got time to fully play with your suggestions. Had to re-code a bit of stuff but the concept works - just like a bought one :~). Many thanks for the solution, Kind Regards, Eric. For those curious - here''s what it was about; On Monday 02 January 2006 02:10, Eric Sloane tried to type something like: > Hi, > I''m trying to figure the most efficient way to

Hi all, My question is somewhat complicated, but bear with me. My project has a number of models: User, Program, and Team. Users belong to multiple Programs. Programs have multiple teams, but Teams belong to one program. For each Program a User belongs to, he can belong to multiple Teams. (Think of this in an athletic context where users are athletes, programs are universities). So my

I am after a nice way to disable (not destroy, delete nor nullify) all associated records. I''m a hoarder, I don''t want to get rid of anything but I want to stop records being visible. I have a disabled boolean in my tables and if I disable the top record in the association (say the association is 5-6 levels deep), I would like to cleanly disable its children. I''ve

Greetings, I''m looking for suggestions on how to simplify getting customer addresses on a form: I''m jumping between controller and view several times; alternating between rhtml and rjs, in order to display customers and their addresses on an invoicing form. It''s very messy. I have a one to many relationship between Customer and Addresses, each customer has one or more

I have a pretty simple model, articles and users. class Article belongs_to :user end class User has_many :articles end In my unit tests I want to ensure that the associations work properly. What''s the best way to do this? The obvious thing to do is a test in each model. # user_test.rb def test_add_post u = users(:first) before_articles = u.articles.count u.articles

Hi Does anyone have a good pattern for using a sinlge form for a model with multiple associations including some has_many''s? For example I have a Property model with a has_one association an Address model and a has_many association to a Highlight model. I would like to update these all on the same page however if I render the main Property form, then use a partial for the address and

hi Guys, Just wondering if we should have some guidelines as to how version specific information should be handled on the wiki ? One way might be to have a version tag on each page on the top right and indicate what Versions that page is going to work with. Then in the body have a Grey bar to indicate version specific info. But this might get a bit messy. Any other ideas ? - KB --

I''m converting our app into restful rails. A couple of my classes (Resource and Asset) have a has_many relationship with each other - here''s the routes: map.resources :assets, :has_many=>[:resources] map.resources :resources, :has_many=>[:assets] I''m getting something weird in my view pages. When i go to /resources/4/assets it works. I go to the page

Relative newbie so would welcome comments re structure of a self-referential relationship I''ve got. It''s started off similar to the Person HABTM friends in the Rails recipes books (working fine), but I needed to turn the join table into a full-blown model as I wanted to add attributes to it. Few tricky bits dealing with the new :through structure and understanding how :scope

Hello, please have a look at this: My tables: create_table :languages do |t| t.column :name, :string, :limit => 3 t.column :title, :string, :limit => 30 end create_table :categories do |t| t.column :category_id, :integer (3.) t.column :created_at, :timestamp t.column :updated_at, :timestamp end create_table :categorytranslations, :id

Hi Everyone, Do I edit the corresponding migration also to show the belongs_to (and the has_many)? I have a many to many relationship where I am using the "has_many :through" association. When I place in the individual classes the ''has_many :through'' and the ''belongs_to'' associations, do I also edit the corresponding migrations to reflect those

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
