@user.task_assignments is a list of tasks, so you can't do
@user.task_assignments.task.name - how should the interpreter know
which task assignment (out of many) you want the task for?
You'll have to iterate through the tasks in some way, for example to
collect all the names:
names = @user.task_assignments.collect { |assignment| assignment.task.name }
or
<% for assignment in @user.task_assignments %>
<%= assignment.task.name %>
<%= assignment.to.name %>
<% end %>
You can also save yourself some typing by declaring
class User
has_many :tasks, :through=>task_assignments
end
Read up on "has_many through", that should give you some ideas.

This may not be exactly how you're setup works, but I think it's accurate. Please let us know how it goes.
