Why this code do not work(permalize is from plug-in):

def before_validation_on_create
permalink ||= name.permalize unless name.nil?
end

Regards

PS.
The method is called but it do not change attribute. How to change it?

I think permalink is treated as a local variable, i.e. local to your
method’s scope. Try self.permalink:

def before_validation_on_create
self.permalink ||= name.permalize unless name.nil?
end

Also have you checked that name isn’t nil?

It works.

Yes of course - many times via ./script/console.
