Question

I have

add_column :foos, :bar_id, :integer

but I wast to be able to do stuff like

@foo.bar.name

rather than

Bar.find(@foo.bar_id)

I think its done with t.references when creating a table… but how do a add it post-table-creating?

Answer 1

You have to edit corresponding model file and add there for example belongs_to declaration. This is exactly what allows you to call the @foo.bar.name.
