  validates_length_of :phone, :is => 10, :message => 'must be 10 digits, excluding special characters such as spaces and dashes. No extension or country code allowed.', :if => Proc.new{|o| !o.phone.blank?}

  validates_length_of :fax, :is => 10, :message => 'must be 10 digits, excluding special characters such as spaces and dashes. No extension or country code allowed.', :if => Proc.new{|o| !o.fax.blank?}

Too small for function, too big to be un-DRY

I wanted to execute the same block of code twice in the same procedure, but the block itself I did not feel warranted its own function (this was in a Rails test). So here's a neat trick to keep it DRY:

    

p = Proc.new do

  r1 = Record.find 1

  r2 = Record.find 2

  r3 = Record.find 3

end



p.call



# ... do some useful stuff ...



p.call # do it again!
