A good example is a LOC record +[RFC1876] which consists of many mandatory and optional parts (degrees, +minutes, seconds of latitude and longitude, altitude or precision). + +It may be difficult to manipulate such DNS records without making a mistake +and entering an invalid value. DNS module provides an abstraction over these +raw records and allows to manipulate each RR type with specific options. For +each supported RR type, DNS module provides a standard option to manipulate +a raw records with format --<rrtype>-rec, e.g. --mx-rec, and special options +for every part of the RR structure with format --<rrtype>-<partname>, e.g. +--mx-preference and --mx-exchanger. + +When adding a record, either RR specific options or standard option for a raw +value can be used, they just should not be combined in one add operation. When +modifying an existing entry, new RR specific options can be used to change +one part of a DNS record, where the standard option for raw value is used +to specify the modified value. The following example demonstrates +a modification of MX record preference form 0 to 1 in a record without +modifying the exchanger: +ipa dnsrecord-mod --mx-rec="0 mx.example.com." --mx-preference=1 + + EXAMPLES: Add new zone: @@ -960,23 +987,23 @@ class LOCRecord(DNSRecord): values=(u'N', u'S',), ), Int('lon_deg', - label=_('Degrees Longtitude'), + label=_('Degrees Longitude'), minvalue=0, maxvalue=180, ), Int('lon_min?', - label=_('Minutes Longtitude'), + label=_('Minutes Longitude'), minvalue=0, maxvalue=59, ), Decimal('lon_sec?', - label=_('Seconds Longtitude'), + label=_('Seconds Longitude'), minvalue='0.0', maxvalue='59.999', precision=3, ), StrEnum('lon_dir', - label=_('Direction Longtitude'), + label=_('Direction Longitude'), values=(u'E', u'W',), ), Decimal('altitude', |
