Hello Guys,
I made a Validator which should check if the value is in the list, but only
if an expression is True.
It works fine BUT it produces no dropdown. Hope you can help me:
Class:
class IS_IN_SET_CONDITIONAL():
def __init__(self, liste, expression, error_message="Value not allowed"
):
self.expression = expression
self.error_message = error_message
self.liste = liste
def __call__(self, value):
if self.expression:
if value in liste:
return (value,None)
else:
return(value, self.error_message)
else:
return (value, None)
Field:
Field("Letter", label="Letter", requires=IS_IN_SET_CONDITIONAL(['A', 'B',
'C'], Expression)),
