set the configured #inheritance_column on #become (#7503) I had to create a new table because I needed an STI table, which does not have both a "type" and a "custom_type" the test fails with: 1) Error: test_alt_becomes_works_with_sti(InheritanceTest): NoMethodError: undefined method `type=' for #<Cabbage id: 1, name: "my cucumber", custom_type: "Cucumber"> /Users/username/Projects/rails/activemodel/lib/active_model/attribute_methods.rb:432:in `method_missing' /Users/username/Projects/rails/activerecord/lib/active_record/attribute_methods.rb:100:in `method_missing' /Users/username/Projects/rails/activerecord/lib/active_record/persistence.rb:165:in `becomes' test/cases/inheritance_test.rb:134:in `test_becomes_works_with_sti' test/cases/inheritance_test.rb:140:in `test_alt_becomes_works_with_sti' 2012-09-02 11:19:50 -04:00			`class Vegetable < ActiveRecord::Base`

rewrite inheritance tests with a custom inheritance_column previously the tests with and without a custom `inheritance_column` used the same models. Since the model then has both fields this can lead to false positives. 2012-09-03 14:30:43 -04:00
