Use helpers within previews

[DEfusion]

I have a preview that requires a form builder passing in, in specs I can create a form using form_with helper but I can't figure out how to get that working in a preview.

I.e. something like:

class MyComponentPreview < ViewComponent::Preview
  def with_defaults
    model = FactoryBot.build(:my_model)
    form_with(model: model) { |f| @form = f }

    render(MyComponent.new(model: model, form: @form))
  end
end

I've tried customising the preview controller and extending our ApplicationController but that doesn't even get to the point of rendering.

I've also tried to see if preview_controller, helpers or helper etc. are available but to no avail.

Hey @DEfusion! These might be available to you if you define your preview as a template – could you give that a shot and let me know if it works?

That worked perfectly, I hadn't thought of doing that. Thanks.
