I'm using the References module in Drupal 7 to do the following: I have projects and clients (content types), so that a project can belong to many clients, and a client can have many projects. I set this up using a Node reference field on the Project content type, which accepts unlimited values. What I need is a view (Views module) that shows a list of clients, and inside each one the projects that belong to it, like this:
Client 1
- project 1
- project 2
Client 2
(no projects)
Client 3
- project 45
- project 2
With links to the projects' pages.
I don't know how the view should be set up. I tried using the User aggregation option in the Advanced section of the view editor, with no luck whatsoever.
