Odd behavior on update

rubyonrails-talk
1

If I have the following two legacy data tables:

CREATE TABLE `statusactivities` (   `id` int(11) NOT NULL auto_increment,   `activity` int(11) NOT NULL default '0' )

CREATE TABLE `activities` (   `id` int(11) NOT NULL auto_increment,   `activity` varchar(60) NOT NULL default '' )

And thus, the two models:

class Statusactivity < ActiveRecord::Base   set_table_name 'statusactivities'   belongs_to :activity, :foreign_key => 'activity' end

class Activity < ActiveRecord::Base   set_table_name 'activities'   has_many :statusactivities, :foreign_key => 'activity' end

and I go to update a Statusactivity, I get the following exception. Please note at the bottom, the parameters -- it doesn;t appear to be anything wrong here to me. Can someone please enlighten me as to what I may have specified wrong here that I am unable to update a record here? (I am using scaffolding_extensions btw) - Ralph Vince

and I go to update a Statusactivity, I get the following exception.

The problem is when you are doing the above activity, can you post the code?

thanks, andy

There isn;t any other than the model descriptions above -- the rest is handled by scaffolding_extensions plugin. -Ralph

You can't have your belongs_to association have the same name as your foreign key. Change the foreign key to activity_id or rename the belongs_to association.
