rspec testing strong params and building a model - ruby-on-rails

Question

I am attempting to write a model test, like so:
require 'spec_helper'
describe Five9List do
before :each do
#five9_list = Five9List.new(name: 'test_list', size: '100')
end
describe "#new" do
it "takes two parameters and returns a Five9List object" do
#five9_list.should be_an_instance_of Five9List
end
end
describe "#name" do
it "returns the correct name" do
#five9_list.name.should eql "test_list"
end
end
describe "#size" do
it "returns the correct size" do
#five9_list.size.should eql 100
end
end
end
Currently, this succeeds and works fine. That's because my model is using attr_accessible, like so:
class Five9List < ActiveRecord::Base
attr_accessible :name, :size
end
If I want to get rid of attr_accessible and follow the rails 4 convention of using strong_params, how would I write that to where my rspec test would still succeed?
Adding this in my controller:
private
def five9_list_params
params.require(:five9_list).permit(:name, :size)
end
And removing attr_accessible does not work.
EDIT
Here is the error I receive from rspec .:

Answer 1

There's nothing wrong with your spec. I can only guess that you're not running Rails 4 or you've installed the ProtectedAttributes gem.
