View users contributed content in profile I have users that have profiles using Profile2 module. I created a content type called Projects. A user can add a project, it has fields: title, description, and file. I would like to add a view to the users profile page that lists all of their Projects. 

How can I connect the profile to the content author and use a contextual filter to get only that users content when viewing their profile?

Any help is greatly appreciated. 

Edit: An example to clarify:
If user1 is logged in and views his profile he will see a list of his projects.

If user1 views user2's profile he will see a list of user2's projects.
In the views UI


Your view must be a view of nodes
Then, add a relationship with the node's author (the relation is: Content: Author)
Then, add an other relationship : select user and check profile. Then you can use the profile node in Contextual filters or Filter criteria. The technic part is that it is a relationship of relationship ;)
