Use domains for fields

[josejachuf]

Do not think it's very difficult to implement the use of domains in the definition of the fields.

A domain is a user-defined custom data type. It is used for defining the format and range of field

Now it can be implemented through a dictionary:

person_name = dict(
type='string',
length=100,
requires=IS_NOT_EMPTY(),
etc,
etc
)
db.define_table('my_table',
Field('name', **dict(person_name))
)

but the proposal is to make it more explicit:

person_name = Domain(
type='string',
length=100,
requires=IS_NOT_EMPTY(),
etc,
etc
)

db.define_table('my_table',
Field('name', domain=person_name)
)

db.define_table('other_table',
Field('other_name', domain=person_name)
)

This is very comfortable when you want to change data types from many fields at once

Please, open discussion in the forum.

This can be a starting point
