Hi!

In one of my current projects, I have an habtm relationship between two models.  To access the table

via console, I created the model for the join table.  so for example, I have

class Foo

  has_and_belongs_to_many :bars, :join_table => 'foo_bars'

I created a FooBar class so I can actually access the records via AR.  My question is this, is it fine to

add another column to this table?

If you are going to add another column to the FooBar table then you might as well change the associations of models Foo and Bar to has_many :foo_bar and then put belongs_to :foo belongs_to :bar in your model FooBar. The point of the has_and_belongs_to_many is to setup a join table for association that you don't plan on accessing through a model or need additional fields for.
