Class Method Details

.flatten_date(dt) ⇒ Object

Convert date into flat, uniform format This method is idempotent: repeated calls give same result.

# File 'lib/wuclan/twitter/model/base.rb', line 35

def self.flatten_date dt
  return dt if dt =~ /\d{14}/
  DateTime.parse(dt).to_flat if dt
end

.unbooleanize(bool) ⇒ Object

Express boolean as 1 (true) or 0 (false). In contravention of typical ruby semantics (but in a way that is more robust for wukong-like batch processing), the number 0, the string ‘0’, nil and false are all considered false. (This also makes the method idempotent: repeated calls give same result.)

def self.unbooleanize bool
  case bool
  when 0, '0', false, nil
    then 0
    else 1
  end
end

.zeropad_id(id) ⇒ Object

Zero-pad IDs to a full 10 digits (the max digits for an unsigned 32-bit integer).

nil id will be encoded as 0. Shit happens and we’d rather be idempotent than picky.

Note that sometime in 2010 (or sooner, depending on its growth rate: in 2008 Dec it was 1.8M/day) the status_id will exceed 32 bits. Something will happen then. This method is idempotent: repeated calls give same result.
