Updating attribute in model

Rails
1

I’m trying to make a change to a field in the model whenever someone
accesses it and it’s incorrect. So I have the following in my
ActiveRecord class:

def status
prev_status = read_attribute(:status)
if end_date < Date.today
update_attribute(:status, “Expired”)
end
status
end

I’m getting a “stack level too deep error”. Any suggestions on how to
fix and the correct approach to this.

thanks

Hi Allen,

I’m not sure, but this seems to be a before or after save filter, if
it’s before_save, instead of update_attribute, just call
write_attribute, when the model is saved it will automatically save
this new value, if it’s an after filter, make it a before one.

You’re calling status from within status so it’s recursing forever.

Replace that last status with read_attribute(:status) after perhaps
reloading the object to ensure you’ve got the latest.

Yeah that is was. Simple calling

‘read_attribute(:status)’ instead of ‘status’ did the trick. thanks
