This module helps to generate HTML forms for creating new database rows
or editing existing rows. It maps column names in a database table to
HTML form elements which fit the schema. Large text fields are turned
into textareas, and fields with a has-a relationship to other
Class::DBI tables are turned into select drop-downs populated with
objects from the joined class.
The module is a mix-in which adds two additional methods to your
Class::DBI-derived class.
This returns a hash mapping all the column names of the class to HTML::Element objects representing form widgets.
This maps an individual column to a form element. The how argument
can be used to force the field type into one of textfield, textarea
or select; you can use this is you want to avoid the automatic detection
of has-a relationships.
Version 1.x of this module returned raw HTML instead of
HTML::Element objects, which made it harder to manipulate the
HTML before sending it out. If you depend on the old behaviour, set
$Class::DBI::AsForm::OLD_STYLE to a true value.
