From 00f55516509770f58f9ce462d45afb80d8f649ca Mon Sep 17 00:00:00 2001 From: Sean Griffin Date: Fri, 4 Jul 2014 14:51:12 -0600 Subject: Add a `required` option to singular associations In addition to defining the association, a `required` association will also have its presence validated. Before: ```ruby belongs_to :account validates_presence_of :account ``` After: ```ruby belongs_to :account, required: true ``` This helps to draw a distinction between types of validations, since validations on associations are generally for data integrity purposes, and aren't usually set through form inputs. --- activerecord/lib/active_record/associations.rb | 10 ++++++++++ 1 file changed, 10 insertions(+) (limited to 'activerecord/lib/active_record/associations.rb') diff --git a/activerecord/lib/active_record/associations.rb b/activerecord/lib/active_record/associations.rb index 6222bfe903..d9b339a1f6 100644 --- a/activerecord/lib/active_record/associations.rb +++ b/activerecord/lib/active_record/associations.rb @@ -1309,6 +1309,10 @@ module ActiveRecord # that is the inverse of this has_one association.
