First we need a table to hold our data
class CreateUsers < ActiveRecord::Migration
def change
create_table :users do |t|
t.string :name
t.string :password
t.string :type # <- This makes it an STI
t.timestamps
end
end
end
Then lets create some ...
By default STI model class name is stored in a column named type. But its name can be changed by overriding inheritance_column value in a base class. E.g.:
class User < ActiveRecord::Base
self.inheritance_column = :entity_type # can be string as well
end
class Admin < User; end
Migr...
Having type column in a Rails model without invoking STI can be achieved by assigning :_type_disabled to inheritance_column:
class User < ActiveRecord::Base
self.inheritance_column = :_type_disabled
end
