There are a number of column types available for use with the web.database.object module. These include:
Each web.database.object column is derived for the corresponding web.form.field field which means it behaves in exactly the same way. You can see the available options in the web.form.field documentation. Each web.database.object column has two more parameters in addition to those of its corresponding web.form.field. These are unique and key described in the previous example.
