Hi list,

the current agility tutorial at http://hobocentral.net/agility-tutorial/
has a little bug in part 3 - the permissions/ edit permissions. To get
the task <-> user association working you must change the line

has_many :users, :through => :task_assignments
to:
has_many :users, :through => :task_assignments, :accessible => true

The version at 
http://github.com/drnic/hobocentral/tree/master/agility-tutorial.markdown
has the outdated statement

has_many :users, :through => :task_assignments, :managed => true

and only the one at http://cookbook.hobocentral.net/tutorials/agility#the_models
reflects it right.

There are also a couple of other adjustments according to the current
permission system.
