Seeking best practise advise

Rails
1

I am doing this app, account - project - category orientated. Category
can belong to an account (url: account.example.com/categories) or
specific to a project (url: account.example.com/projects/1/
categories), my question is:

  1. is this url structure the proper way to do it?
  2. inside the category controller, to determine whether the category
    belong to an account or a project, i use “if param[‘project_id’]”,
    again is this the proper way to do it?

Appreciate any help,

Regards,

johnny
