Greetings,
I''ve been getting an error all afternoon and haven''t been
able to
figure it out; any help would be wonder full.
Models-----
class Project < ActiveRecord::Base
belongs_to :job
belongs_to :thumbnail, :class_name => ''Image'',
:foreign_key =>
''image_id''
has_and_belongs_to_many :services
end
class Thumbnail < Image
has_one :project
end
Controller------
class Admin::ProjectsController < ApplicationController
def save
.
.
. # thumbnail image has been uploaded, created, and added to
@project.thumbnail
#if there''s an id then do an update otherwise it''s a new
project so
do a save
if params[:id]
@s1 = @project.thumbnail.save if @project.thumbnail
@s2 = @project.update_attributes( params[:project] ) # this is
the line which fails
@saved = ( @s1 == false || @s2 == false ) ? false : true
else
@saved = @project.save
end
if @saved # decide what to render or where to redirect, etc.
.
.
.
end
end
I only run into problems when no thumbnail has been previously saved and
the thumbnail I''m trying to save is invalid (ie. fails to save). If a
thumbnail has already been saved then uploading a new, invalid thumbnail
is handled perfectly. It also doesn''t matter if the Project is being
saved for the first time or updated.
Here''s the full error I''m getting:
ArgumentError in Admin/projectsController#save
wrong number of arguments (1 for 0)

Lastly it doesn''t crash till after the after_validation callback.
I''m stymied. Any insight would be great.
Thanks William

Chris T wrote:> Which is line 48 > (#{RAILS_ROOT}/app/controllers/admin/projects_controller.rb:48)?line 48 is: @s2 = @project.update_attributes( params[:project] ) I get the error for both Project#update_attributes and Project#save when the referenced (belongs_to) Thumbnail fails validation and does not save. Also this only happens if there has never been an associated Thumbnail. Once one is successfully associated it''s no longer a problem. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I figured it out a solution but I don''t feel 100% why I was getting this error. If anyone has any insight I''d still love to hear it. The solution was simple, I added: validates_associated :thumbnail to my Project model and all is good. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
