How do you designate private or protected attributes in Ruby/Rails?

Question

Are all DB fields automatically attributes, and don't need to be defined in the Model?

Any recommended tutorials?

Working in Rails 3.0.7.

The title doesn't match the question.

Yes, DB fields are automatically attributes (depending on what you mean by attribute; they're not simply @column_name as with attr_accessor).

You can provide some level of accessibility by using attr_accessible and attr_protected, but that's for mass-assignment, not general access.

You can use attr_protected, attr_accessible or attr_readonly

The attr_protected, attr_readonly and attr_accessible macros control what is accepted for mass-assignment. Read those links if you’re not familiar with the difference between those three macros.
