Hi Guys!
I've got a little problem trying to use Virtual Fields. I can't make them
work. I follow the example in the book and nothing, I don't have a clue of
what I'm doing wrong...
The idea is to have a virtual field that calculates the age of the person
based on his day of birth...
Here is the model:
db.define_table('personal_data',
....., # another fields
Field('dob', 'date', requires=IS_DATE()),
....., # more fields
auth.signature
)
db.personal_data.age = Field.Virtual('age', lambda row:
diff_in_years(row.dob))
Where the auxiliary function is:
from dateutil import relativedelta as rdelta
def diff_in_years(date):
try:
return rdelta.relativedelta(datetime.datetime.today().date(),
date).years
except:
return None
And here is my test controller:
def prueba():
response.flash = db.personal_data(uid=auth.user.id).age
The traceback says that "Row" doesn't have the attribute "age".
I've also tried with a method (Field.Method), with no luck. I always have
the same error....
Any help would be appreciated!
