Hey guys and gals,
I have the following object that has acts_as_versioned:
class Note < ActiveRecord::Base
acts_as_versioned
belongs_to :user
end
The schema for my notes table is as follows:
create_table :notes, :force => true do |t|
t.column :id, :integer
t.column :noteshare_id, :integer
t.column :user_id, :integer
t.column :title, :string
t.column :content, :text
t.column :created_at, :datetime
t.column :updated_at, :datetime
t.column :version, :integer
end
Note.create_versioned_table
Now I want to be able to do:
<% @notes.versions.each do |version| %>
<%= version.user.fullname %><br/>
<% end %>
But I can''t!
User is not associated with versions. How can I associate it?
Thanks for your help :-). This has been bugging me for a long time.

I think what you''ll need to do is create a DocumentVersion model and adds a belongs_to to that. I think it would work then.

I haven''t bothered to update the gem or rdocs though, plugins are more agile. And I don''t have that stuff all set up on my powerbook yet. I''m quite sure this will require edge rails too. Note: this creates an extension module that will be applied to both Note and Note::Version. No need to call belongs_to on the model then. http://techno-weenie.net/svn/projects/plugins/acts_as_versioned/lib/acts_as_versioned.rb -- Rick Olson http://techno-weenie.net

I think it would work then.If you want to modify the versioned class, try this: class Note < ActiveRecord::Base belongs_to :user end Note.versioned_class.class_eval do belongs_to :user end This will work on older versions of acts_as_versioned too. -- Rick Olson http://techno-weenie.net
That is great Rick. I can''t test it though because my application for some odd reason does not like edge rails. I am always getting unitialized constant. Any insight into that? :-) On 13-Feb-06, at 8:06 PM, Rick Olson wrote:> On 2/13/06, John Kopanas <john@protoseinc.com> wrote: >> Hey guys and gals, >> >> I have the following object that has acts_as_versioned: >> >> class Note < ActiveRecord::Base >> acts_as_versioned >> belongs_to :user >> end >> >> The schema for my notes table is as follows: >> >> create_table :notes, :force => true do |t| >> t.column :id, :integer >> t.column :noteshare_id, :integer >> t.column :user_id, :integer >> t.column :title, :string >> t.column :content, :text >> t.column :created_at, :datetime >> t.column :updated_at, :datetime >> t.column :version, :integer >> end >> Note.create_versioned_table >> >> Now I want to be able to do: >> >> <% @notes.versions.each do |version| %> >> <%= version.user.fullname %><br/> >> <% end %> >> >> But I can''t! >> >> User is not associated with versions.

This will work for me. My natural followup questions to this is how can two versioned classes be linked together? Assuming Parent has_many Children and a Child belongs_to Parent, I would want Parent_version to have_many Children_Version and a Child_Version to belong_to Parent_version. Is this easily doable ?

Rick Olson wrote:> Try this: > > class Thing < ActiveRecord::Base > acts_as_versioned do > belongs_to :user > end > endI think I must be misunderstanding something, or doing something wrong. When I modified my acts_as_versioned class (in my case "Thing") as described above, I get a NoMethodError: undefined method ''belongs_to'' for #<Module:0x2791c00>. Alternatively, I tried>class Thing < ActiveRecord::Base > belongs_to :user >end > >Thing.versioned_class.class_eval do > belongs_to :user >endand while there are no errors, eager-loading doesn''t happen when I''m viewing one of my versions. I''m using EdgeRails, and version 0.5.1 (Oct 5, 2006) of the AAV plugin. If it makes a difference, my user model is provided by ActsAsAuthenticated, and the related fields in my Thing model (created_by, and updated_by) are being handled dynamically by the userstamp plugin ( http://delynnberry.com/projects/userstamp/ ). If there are any pertinent details that I''m leaving out, please let me know! Any pointers anyone could offer would be very much appreciated! -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Gwen Campbell wrote:> I think I must be misunderstanding something, or doing something wrong.Murphy must have a law, yes, stating that one will only realize the solution *after* publicly asking for help :) The issue, of course, was that I was not specifying the foreign_key in the versioned table. Thing.versioned_class.class_eval do belongs_to :created_by, :class_name => "User", :foreign_key => "created_by" belongs_to :updated_by, :class_name => "User", :foreign_key => "updated_by" end is what was needed. I''m still not clear why class Thing < ActiveRecord::Base acts_as_versioned do belongs_to :created_by, :class_name => "User", :foreign_key => "created_by" belongs_to :updated_by, :class_name => "User", :foreign_key => "updated_by" end end doesn''t do the same, but that''s academic at this point. :) -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
