Rails validates_uniqueness_of with a :conditions param

validates_uniqueness_of :prod_id, :scope => [:col_id, :parent_col_id], :conditions => lambda { |table| table[:state].not_in(%w(cancelled denied)) }

I can't find any documentation for passing :conditions to validates_uniqueness_of... I'm looking for an explanation.

Update - thanks for the answer, a custom validation or using if or less would make sense... however this is pre-existing code that I'm trying to fully understand before changing.

You can make your own validation method for this. For example:

validates_uniqueness_of :prod_id, :scope => [:col_id, :parent_col_id],
                                  :if => :custom_validation

def custom_validation
  #your code here
end
