Possible improvements

[max-si-m]

Hello, I've been recently integrated with your gem, and that is a wonderful piece of art. Helped me a lot, thank you. You did a great job.

I found some places that might be improved or changed according to my understanding:

• Some models missed the dependent and inverse_of for associations.

• No generator for models (needed for sharding and fixing associations).

• No way to attach API routes without a dashboard, when the dashboard isn't required or forbidden.

• Shouldn't the line 27 be moved to the 32? Is there a reason to generate stale pkpass?

  passkit/app/controllers/passkit/api/v1/passes_controller.rb

  Lines 27 to 32 in c7ef36a

  	pass_output_path = Passkit::Generator.new(pass).generate_and_sign
  	response.headers["last-modified"] = pass.last_update.httpdate
  	if request.headers["If-Modified-Since"].nil? ||
  	(pass.last_update.to_i > Time.zone.parse(request.headers["If-Modified-Since"]).to_i)
  	send_file(pass_output_path, type: "application/vnd.apple.pkpass", disposition: "attachment")

• I was curious what is the reason for having multiple passes per one generator? I mean when we have the same class for pass and generator. I've patched that to use find_or_create_by! but I'm wondering, maybe I'm missing something? Wouldn't it create a lot of redundant records?

  passkit/lib/passkit/factory.rb

  Lines 5 to 7 in 3522c16

  	def create_pass(pass_class, generator = nil)
  	pass = Passkit::Pass.create!(klass: pass_class, generator: generator)
  	Passkit::Generator.new(pass).generate_and_sign

Maybe those findings would be helpful. If they are helpful somehow, I can help with some of them if needed.
