Conditional validation in Rails

Question

I have a model. In some cases I need to validate all its fields for presence and another kinds of stuff, in other cases I need to validate only some of them and other fields can remain empty. What's the best way to achieve this?

Check this

validates_presence_of :state, :if => :in_us?

def in_us?
  country == 'US'
end

Here it validates presence of state only if country is US. For other country id dosen't validates state.
