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
has_and_belongs_to_many :bars, :join_table => ‘foo_bars’
I created a FooBar class so I can actually access the records via AR.
question is this, is it fine to
add another column to this table?
