Rails: class_name can be a class

[ainar-g]

Steps for reproduction:

0. Create an empty rails application with rails new foo

1. Create two models:

   class A < ActiveRecord::Base
     has_many :bs, class_name: B
   end

   class B < ActiveRecord::Base
     belongs_to :a, class_name: A
   end

2. Create a test:

   require 'test_helper'
   
   class ATest < ActiveSupport::TestCase
     test "one" do
       a = A.new
       assert a
     end
   end

3. Configure RDL:

   RDL.config { |config|
     config.type_defaults = { wrap: true, typecheck: :now }
   }

4. rake

Result:

  1) Error:
ATest#test_one:
RDL::Type::TypeError: ActiveRecord::Associations::ClassMethods#has_many: Argument type error.
Method type:
        (Symbol or String name, ?{ (?ActiveRecord::Base) -> %any } scope, { class_name: ?(Symbol or String), foreign_key: ?(Symbol or String), foreign_type: ?(Symbol or String), primary_key: ?(Symbol or String), dependent: ?(:delete_all or :restrict_with_error or :restrict_with_exception or :nullify or :destroy), counter_cache: ?(false or true or Symbol or String), as: ?(Symbol or String), through: ?(Symbol or String), source: ?(Symbol or String), source_type: ?(Symbol or String), validate: ?(false or true), inverse_of: ?(Symbol or String), extend: ?(Array<Module> or Module) }) ?{ () -> %any } -> %any
Actual argument types:
        (Symbol, Hash) 
Actual argument values (one per line):
        :bs
        {:class_name=>B(id: integer, a_id: integer)}

    app/models/a.rb:2:in `<class:A>'
    app/models/a.rb:1:in `<top (required)>'
    test/models/a_test.rb:5:in `block in <class:ATest>'

1 runs, 0 assertions, 0 failures, 1 errors, 0 skips

I guess types for associations should include Class.

Thanks! This is fixed in dev and will be merged into master shortly.
