Class Method Details

.asc(*args) ⇒ Object

Returns an instance of Order::Asc where args is either a single or array of Symbol representing columns.

Eases the use of class Order::Asc. You can use it whenever selecting rows or in #default_order.

order_lower = Momomoto.asc( :person )
  => #<Momomoto::Order::Asc:0x5184131c @fields=[:person]>
Table.select( {}, {:order => order} )
  => returns Table's rows ordered asc by column person

# File 'lib/momomoto/base.rb', line 44

def asc( *args )
  Momomoto::Order::Asc.new( *args )
end

.desc(*args) ⇒ Object

Returns an instance of Order::Asc where args is either a single or array of Symbol representing columns.

Eases the use of class Order::Desc. You can use it whenever selecting rows or in #default_order.

order_lower = Momomoto.lower( :person )
  => #<Momomoto::Order::Desc:0x5184131c @fields=[:person]>
Table.select( {}, {:order => order} )
  => returns Table's rows ordered desc by column person

end

.lower(*args) ⇒ Object

Returns an instance of Order::Lower where args is either a single or array of Symbol representing columns.

Eases the use of class Order::Lower. You can use it whenever selecting rows or in #default_order.

order_lower = Momomoto.lower( :person )
  => #<Momomoto::Order::Lower:0x5184131c @fields=[:person]>
Table.select( {}, {:order => order} )
  => returns Table's rows ordered case-insensitively by column person
