rspec testing strong params and building a model

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 .:

Failures:

  1) Five9List#name returns the correct name
     Failure/Error: @five9_list.name.should eql "test_list"

       expected: "test_list"

  2) Five9List#size returns the correct size
     Failure/Error: @five9_list.size.should eql 100

       expected: 100

u are requiring wrong param (:name) check your params properly and pass it inside require()...here i think it should be require(:five9_list).....if u are using rails default REST routes — Rahul Singh

I fixed the above, and I am using default REST routes. Still no luck though. — Luigi

Your test doesn't involve any controller code, so nothing in your controller matters and your routes don't matter either. — Peter Alfvin

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.

I do have the appropriate columns in my DB. Still no dice.

Nailed it. I had the ProtectedAttributes gem installed, I was thinking that only added functionality - not hindered the strong_params functionality. Thanks for the tip!
