Just an update and a request, if anyone might be able to help.

The patch works and merges fine, but @eviltrout wanted me to add a controller spec that checks for class\_name in the record being viewed, and assigns the `embeddable_css_class` variable for embedding in the template.

I am not having any luck getting it to work despite a great pointer to exactly where I should be looking:

I have modified **spec/controllers/embed\_controller\_spec.rb** down in the context `"with multiple hosts"` so the last call to Fabricator should include a class\_name:

```plaintext
...
Fabricate(:embeddable_host, host: 'https://example.com', class_name: 'example')

```

Following @eviltrout’s guidance, I then added a new test to check, but this is not working. ☹

```plaintext
    it "contains custom class name" do
      controller.request.stubs(:referer).returns("https://example.com/some-other-path")
      get :comments, embed_url: embed_url
      expect(assigns(:embeddable_css_class)).to eq('example')
    end

```

I’m apologize if I’m a little dense, but I could really use a hand here figuring out how to get this last bit working.
