set_fixture_class

Importance_2
Ruby on Rails latest stable (v4.1.8) - 1 note - Class: ActiveRecord::TestFixtures::ClassMethods
set_fixture_class(class_names = {}) public

Sets the model class for a fixture when the class name cannot be inferred from the fixture name.

Examples:

set_fixture_class some_fixture:        SomeModel,
                  'namespaced/fixture' => Another::Model

The keys must be the fixture names, that coincide with the short paths to the fixture files.

Use it to solve FixtureClassNotFound errors.

If you are using a non standard table name by means of set_table_name in your model:

class MyClassName < ActiveRecord::Base
  set_table_name "mytablename"
end

then you will get FixtureClassNotFound errors when you try to use fixtures in you unit tests. To solve this use set_fixture_class inside your test:

require 'test_helper'
class MyClassNameTest < ActiveSupport::TestCase
  set_fixture_class :mytablename => MyClassName  
end

and rename your fixture file to mytablename.yml
