Hello All
consider the example model file below :
db = DAL('sqlite://storage.sqlite')
signature = db.Table(db,'auth_signature',
Field('created_on','datetime',default=request.now,
writable=False,readable=False, label=T('Created on')),
Field('created_by',auth.settings.table_user,default=auth.user_id,
writable=False,readable=False, label=T('Created by')),
Field('modified_on','datetime',update=request.now,default=request.
now,
writable=False,readable=False, label=T('Modified on')),
Field('modified_by',auth.settings.table_user,
default=auth.user_id,update=auth.user_id,
writable=False,readable=False, label=T('Modified by'))
)
db._common_fields.append(signature)
db.define_table('mytable',Field('myfield','string'))
db.mytable.myfield.requires = IS_EMPTY_OR(IS_URL())
Then, if I want to activate lazy_tables
db = DAL('sqlite://storage.sqlite', lazy_tables=True)
I got the following error that I don't really understand.
Can anyone explain me?
Thank you
