Consider a case where I have a functional JSON backend, and the admin-on-rest resources company, user and company_user.

The data is as follows

company

• id
• name
• address ...etc.

user

• id
• name
• phone
• address ...etc.

company_user

• id
• company_id (references company)
• user_id (references user)
• position ...etc.

It is very easy to have a separate top-level resource view for the company_user resource type; but it should really be editable per user and per company, on preferably on a tab of the user, or the company resource views.

Thus comes the problem: how to create a tab for user resource, where I can list the current company-references (company_user rows), but in the same tab I need a sane way to do the following functionality:

1. search for all the companies that are not currently referred to by this user (of course there is an API call for that);
2. add a row to to the company_user collection and;
3. refresh the tab
