+tip-description: Setting a default vaue for a field in rails 5 without using a migration.
+
+---
+
+
+We used to write a migration or a before save method for setting a default vale to a field, but in Rails 5 this has been made much easier bu using [attribute API](http://guides.rubyonrails.org/5_0_release_notes.html)
+you can mention the default value of the attribute as
+
+```ruby
+    class User < ApplicationRecord
+        attribute :status, default: "registered"
+    end
+```
+
+```ruby
+User.new => #<User id: nil, first_name: nil, last_name: nil, user_name: nil, email: nil, status: "registered">
+```
