Could someone explain this?
#config/initializers/ar_attributes.rb
module ActiveRecord
module AttributeMethods
alias_method :ar_read_attribute, :read_attribute
def read_attribute(attr_name)
p "read_override"
ar_read_attribute(attr_name)
end
alias_method :ar_write_attribute, :write_attribute
def write_attribute(attr_name, value)
raise 'You made it!'
end
end
end
In the Rails console:
>> person.read_attribute :name
"read_override"
=> "Joe"
>> person.write_attribute :name, "Bilal"
=> "Bilal"
>> person.read_attribute :name
"read_override"
=> "Bilal"
