search for: custom_fields

...an application where I want the ability to customize a blog post with custom fields. The custom fields come in 2 types , global and user. global custom fields should appear on EVERY initial blog post, and the user ones can be added optionally. At this point, I have for the post model a has_many:custom_fields, but I have no idea how to implement the ability to have an interface where the custom fields always display (along with their values), and any custom user fields that have since been associated with the post. Any ideas?
