User roles, authorisation, on specific projects

Rails
1

Hello,

Currently I am working on a app, so far I have User (with devise) which
are
able to create projects. So, if user1 create project A and project B I
want him, to be able to assign user2 with role admin on project A, and
user2 with moderator admin on project B.
I was thinking in creating a UserRoleProject link table, is it a good
idea?
Also I intend to use CanCan for the authorisation.

Thank you

Thinking more about this, I realised that I should have the fallowing
associations. User has_many Projects, Project belongs_to User, User
has_many UserRole, UserRole belongs_to User, Projects has_many UserRole,
UserRole belongs_to Project, Role has_many UserRole, UserRole belongs_to
Role, is this right?

That should work, however if you had a role of Creator or Owner then
you could also setup the creation through the link table and would not
need the direct association between user and projects.
