Very usefull, I think it need to be included in web2py, maybe in DAL.Field
as a static method.
something like
# define field templates
fieldtemplate = dict(
text = Field('name','text',requires=IS_NOT_EMPTY(), represent=...),
integer = Field('name','integer',.....)
)
# define tables
db.define_table('somthing',
Field('x'),
Field.template(text,'myfieldname')
)
Your like function go in Field.template static_method
