Here goes an example
class Person(Entity):
has_field('name',Unicode,required=True)
has_field('lastname',Unicode,required=True)
has_field('title',Unicode)
Assuming I have a list of like this dictionaries: people =
[ { 'title':'Mr','name':'Darth','lastname':'Vader' },
{'name':'Luke','lastname':'Skywalker'} ]
for person in people:
Person(person)
If title is missing from the dictionary then it is assumed to be None.
This example is very simple but I have a few tables where a lot of
missing fields can happen. I like this more than:
if not people.has_key(title):
title = None
else:
title = people['title']
Person(name=name,lastname=lastname,title=title)
Thanks!
