Hi
In my database i have a number field i have somethig like this
db.define_table("Inventory",
Field("idProduct", db.Product, label="Product"),
Field("quantity", "integer", default=None, label="Quantity"))
db.Inventory.idProduct.requires=IS_IN_DB( db, 'Product.id', ' %
(nProduct)s ')
If i want to leave the field quantity empty, it shows me that i must
put a numer between some range. Is there a way to put this field empy?
Other validation i have problem is inserting states
db.define_table("State",
Field("idCountry", db.Country, label="Country"),
Field("nState", "string", default=None, label="State", notnull=True,
ondelete='CASCADE'))
I cant put is_not_in_db() in nState, because
I have a state named Alberta in canada, but maybe is there a state
Alberta in other country if i put this, i cant insert the state
alberta in both countries. But if i dont do this i can insert Alberta
in Canada a lot of times.
so, is there a way to validate both fields in the model?
