Hi, i use this code in my application, it works very good when i
insert a new record, but i have a little problem when i want to update
a registry. For example:
I have un my table inventory: product, country, quantity
If i insert pencil, canada, 40 it inserts fine
then if i want to insert again pencil, canada, 50 it doesnt insert
beacuse i already have pencils in canada. This is working fine.
My problem is here, in the update. For example
I want to update my number of pencils in Canada, beacause i buy
another 50 pencils. I put update
pencil, canada, 90
But it says it already have pencils in canada, its like i am inserting
a new registry and not doing an update. How can i solve this?
This is my validator, is in the model:
class IS_NOT_IN_DB_DDOWN_UIM(IS_IN_DB):
def __init__(self,*a,**b):
IS_IN_DB.__init__(self,*a,**b)
def __call__(self,value):
e=IS_IN_DB.__call__(self,value)
if e[1]:return e e=IS_NOT_IN_DB(db
(db.Inventory.idProduct==request.vars.idProduct),'Inventory.idCountry',error_message=self.error_message)
(value)
return e
db.Inventory.idCountry.requires=IS_NOT_IN_DB_DDOWN_UIM
(db,'Country.id','%(nCountry)s',error_message="The product is already
in this country.")
