Can someone explain strict mass assignment in Rails 3.2?

I'm just getting up to speed with Rails 3.2, and when I use create or update_attributes, I always seem to get mass assignment errors. Is this normal? How should I be creating and updating records?

add the attributes you want to set via massassignment to the whitelist in the model attr_accessible :my_attribute

allowing to set related nested model-attributes through the same form, you have to set an accepts_nested_attributes_for for this model and add the attributes to the whitelist attr_accessible :$RELATED_MODEL_attributes

read those links. http://api.rubyonrails.org/classes/ActiveModel/MassAssignmentSecurity/ClassMethods.html
