Odd behavior on update

Rails
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 V.

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

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.
