Is it possible to rename a foreign key?

Question

Ruby on Rails

Is it possible to remove the prefix _idfrom a foreign key?
New table. two models OrderandProduct

class Order < ApplicationRecord
  has_many :products
end
class Product < ApplicationRecord
  belongs_to :delivery, :class_name => "Order"
end

t.integer :delivery, index: true
I make an error in the products table :

ActiveRecord::AssociationTypeMismatch: Order(#85313090) expected, got 1 which is an instance of Fixnum(#73138750)

How to fix?

Answer 1

It is possible through foreign_key, but why does delivery_id not suit you?
