Revision 3973 - Directory Listing
Modified Wed Jan 25 23:13:56 2006 UTC (7 years, 4 months ago) by sh002i

forward-port from rel-2-2-dev: (update copyright date range -- 2000-2006.
this is probably overkill, since there are some files that were created
after 2000 and some files that were last modified before 2006.)

ordering, normalizers, booleans, documentation. details:

* changed order of table classes so that the has_a() part of a
  relationship occurs before the has_many() part.
* added WeBWorK::DBv3::NormalizerMixin, simiar to Class::Trigger, to
  manage normalizer subroutines for per-column normalization.
* overloaded normalize_column_values to all normalizers for changed
  fields.
* implemented predefined has_a_boolean() normalizer definition.
* defined boolean fields in tables using has_a_boolean().
* added/clarified docs.

still to do:

* add inflators/deflators for durations

Revision 3010 - Directory Listing
Added Tue Nov 23 02:50:13 2004 UTC (8 years, 6 months ago) by sh002i

preliminary WWDBv3 support.

Features:

* automatic schema updating (see WeBWorK::DBv3::Utils).
* basic table structure constructed by set_up_table().
* has_a/has_many relationships declared explicitly.
* works!

Limitations:

* uses Class::DBI::mysql explicitly. Needs to use BaseDSN instead.
* connection information is currently hardcoded into DBv3.pm. It needs
to be brought in at compile time, so there are constraints on how this
can be done.
* no wrappers for LOCK/UNLOCK TABLES yet.
* no inflating/deflating for dates, comma separated lists, etc. yet.
* basically no testing.
