How to assign a model to a resource?

In Laravel Route::resource('foo', 'AnyController') will generate the following routes:

GET foo
GET foo/create
POST    foo
GET foo/{foo}
GET foo/{foo}/edit
PUT foo/{foo}
PATCH   foo/{foo}
DELETE  foo/{foo}

I need to bind a different model in routes. How to get it to produce the following urls instead?

GET foo
GET foo/create
POST    foo
GET foo/{bar}
GET foo/{bar}/edit
PUT foo/{bar}
PATCH   foo/{bar}
DELETE  foo/{bar}
