Error on Save

Rails
1

Hi,

i have a model that extends AcitveRecord::Base called PhoneUser. This
table has a field called hits in it. This is set to default at 0. When
I try and increment the value for hits in a controller I get the
following error

wrong number of arguments (1 for 0) and points to line 57

My code is

@phone_user = PhoneUser.find(uaid)
@phone_user.hits += 1
@phone_user.save

If I remove the line @phone_user.hits += 1 then it works fine, with no
errors

Has anyone got any ideas

line 57 is the line
@phone_user.save

read the rails doc
look at the AR function increment!
