Given the code from the Complex Form part III how would you go about testing the virtual attribute?
def new_task_attributes=(task_attributes)
task_attributes.each do |attributes|
tasks.build(attributes)
end
end
I am currently trying to test it like this:
def test_adding_task_to_project
p = Project.new
params = {"new_tasks_attributes" => [{ "name" => "paint fence"}]}
p.new_tasks_attributes=(params)
p.save
assert p.tasks.length == 1
end
But I am getting the following error:
NoMethodError: undefined method `stringify_keys!' for "new_tasks_attributes":String
Any suggestions on improving this test would be greatly appreciated.
