i have created a scaffold Zone witch contain : name , interface and
description as attribute
all works fine but when i add this line to my model :
class Zone < ActiveRecord::Base
validates_presence_of :name, :message => "Missing name "
i have an error when the name is empty !
this is the error :
You have a nil object when you didn’t expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.inject
