Rails - Aug 2006 - Applying foreign key during initialize gives me a view error

Hi all,

I''m trying to set the foreign key of a new Company entity to the 
organization id I have in the session.

Here''s the code in Company...
==============================
   def initialize(org_id)

      if !org_id.nil?
         # Link new company to the organization logged in.
         @organization_id = org_id
      end

   end

==============================
...here is the calling code, inside company_controller#edit :

==============================
     @company = params[:id] ? Company.find(params[:id]) : 
Company.new(session[''org_id''])

==============================
...and finally here is the edit.rhtml view:

==============================
<%= form_tag :controller => "company", :action =>
"edit", :id =>
@company %>
<%= render(:partial => ''company_form'') %>
<%= end_form_tag %>

==============================
...but I am getting this error when the view is called:

==============================
You have a nil object when you didn''t expect it!
You might have expected an instance of Array.
The error occured while evaluating nil.[]

Extracted source (around line #2):

1:
2: <%= form_tag :controller => "company", :action =>
"edit", :id =>
@company %>
3: <%= render(:partial => ''company_form'') %>
4: <%= end_form_tag %>

==============================
Can someone see what it is complaining about?

Thanks,
Michael

You need to call super in initialize to allow ActiveRecord
to do its stuff first.

Also, did you mean to set the organization_id attribute
rather than an organization_id instance variable?

def initialize(org_id)
   super
   # Link new company to the organization logged in.
   self.organization_id = org_id if org_id
end
