Hi,
I’d like to upcase a variable before it is saved, but I’m not sure how
to access the incoming param or where this work should be performed:
In my update method, I have:
@device = Device.find(params[:id])
params[:device[macaddress]].upcase <-- problem code
if @device.update_attributes(params[:device])
…usual stuff here
‘macaddress’ is the variable I’d like to upcase.
Does anybody have suggestions?

Nic,
In your model, I think you want to hook into the before_save callback,
like:
before_save :normalize
def normalize
macaddress.upcase!
#other modifications here
end
Hope that helps,
Regards,
Ed C.

You could use a before_save callback in the Device model.
class Device < ActiveRecord::Base
before_save :normalize_macaddress
…
private
def normalize_macaddress
self.macaddress = macaddress.upcase if macaddress
end
end
