thanks help!

check if have run migration, , if in migration file there active column.

for redoing migrations use:

rake db:reset db:migrate 

edit

now understand problem, active method belongs user not customer.

so first think should take @ this post regarding default_scope. achieve want may use method active in customer this:

def active   self.user.active end
