Turbolinks is like an electric car...it's so smooth, you don't even know it's working. And from a UI perspective, that can be bad.

The git page in one of it's examples has this:

document.addEventListener("page:fetch", startSpinner);
document.addEventListener("page:receive", stopSpinner);

I'm not sure if I like this. It's like adding a fake engine noise that is louder than a regular engine.

I'm curious if anyone has any good solutions.

Not sure if this is the most elegant, but this works if you want permission.rb working with Carrierwave.

allow_nested_param :post, :photos_attributes, [:image]

def allow_nested_param(resources, attribute, nested_attributes)
  @allowed_params ||= {}
  Array(resources).each do |resource|
    @allowed_params[resource.to_s] ||= []
    @allowed_params[resource.to_s] += [{ attribute.to_s => Array(nested_attributes).map(&:to_s)}]
  end
end
