Question

I’ve created a table with a references column in an earlier migration and now I would like to drop it. I know I can do a call to remove_column on the generated name, but is there a way to remove it using the the table name instead?

remove_references :blah, :users instead of remove_column :blah, :user_id

There is the method aptly named remove_references, as you guessed. It only needs one parameter, same as references needs one parameter too:

From the API documentation:

remove_references(*args)

#Removes a reference. Optionally removes a type column. remove_references and
#remove_belongs_to are acceptable.
Examples

 t.remove_references(:goat)
 t.remove_references(:goat, :polymorphic => true)
 t.remove_belongs_to(:goat)
