Specify custom index name when using add_reference

Question

I have the following migration

class LinkDoctorsAndSpecializations < ActiveRecord::Migration
  def up
    add_reference :doctors, :doctor_specialization, poly         


        

Answer 1

I would not suggest leaving out "add_reference", but you could leave out the "index" option hash key and then use "add_index":

add_reference :table, :column
add_index :table, :column, :name => 'index_table_column'

Or, the more appropriate way would be like this:

add_reference :doctors, :doctor_specialization, polymorphic: true, index: { name: 'index_doctors_doctor_specialization' }
