Workaround for rspec-fire "does not implement" errors with ActiveRecord models

spec_helper.rb

# inside config.before(:suite)
 
ActiveRecord::Base.subclasses.each do |model_class|
  columns = model_class.columns.map { |c| c.name.to_sym }
  missing = columns - model_class.instance_methods
 
  missing.each do |column|
    model_class.send(:define_method, column) { |*args| super(*args) }
  end
end
