Tangram::DateTime - map date & time fields


   use Tangram;

   # any of:
   use Tangram::RawDate;
   use Tangram::RawTime;
   use Tangram::RawDateTime;
   use Tangram::DMDateTime;

      classes => { NaturalPerson => { fields => {
         rawdatetime => [ qw( birth death ) ],
         rawdate => [ qw( depart return ) ],
         rawtime => [ qw( breakfast lunch dinner ) ],
         dmdatetime => [ qw( attack retreat ) ],


These classes are responsible for mapping strings to SQL date or time types. These classes are not imported by, thus they must be explicitly imported via a use directive.

The three typetags rawdate, rawtime and rawdatetime are for mapping strings to SQL date/time types. 'Raw' means that Tangram doesn't attempt to interpret the strings, it merely passes them down to DBI.

dmdatetime is like rawdatetime except that the date is converted to the Date::Manip internal format. This mapping was contributed by Gabor Herr <>.

The persistent fields may be specified either as a hash or as an array of field names.

In the hash form, each entry consists in a field name and an associated option hash. The option hash may contain the following fields:

col sets the name of the column used to store the field's value. This field is optional, it defaults to the persistent field name. Override if the field name is not an acceptable SQL column name.

sql sets the SQL type of the column. Used by Schema::deploy() when initializing a database. Defaults to 'VARCHAR(255) NULL' for strings, 'INT NULL' for ints and 'REAL NULL' for reals.

The persistent fields may also be specified as an array of strings, in which case the defaults are used.
