Restrict attributes in to_xml

Rails
1

For example, let’s say I have a User model with 2 attributes:

  1. pw_hash
  2. pw_salt

I don’t want these to show up in the to_xml method. How do I keep to_xml
from using these attributes?

You can specify what you don’t want using except:

user.to_xml :except => [: pw_hash, : pw_salt]

Look at the :except option:
http://rails.rubyonrails.org/classes/ActiveRecord/XmlSerialization.html#M000910

If you want to make this default you can just override it in your model:

to_xml(options = {})
super(options.update(:except => [:pw_hash, :pw_salt]))
end
