Hi Colin,

It is best not to top post as doing this makes it more difficult to follow the thread, and also makes it easier to reply to the wrong person.  cyber c was the original poster.  Best to insert your reply at appropriate points in the previous message.
 

   I think u r using rails 3.2.x where mass assignment is protected for saving the record into the db
you need to write this piece of code in model

attr_accessible : field/column name

Also if you had posted this after my comment which said

"You probably need to add the new field to the attr_accessible list in
the model.rb file so you can do such things as update_attributes(
params[...])  or new( params[...] )"

then you would have noticed that I had already answered the question.

You probably need to add the new field to the attr_accessible list in
the model.rb file so you can do such things as update_attributes(
params[...])  or new( params[...] )
