sigma.core
sigma.core is a validation framework.
Example
from sigma.core import Model, ErrorContainer, asdict, validate
from sigma.standard import Field
class User(Model):
id = Field(type=int, size=(5, 10))
password = Field(type=str, length=(8, 15))
user = User()
user.id = 5
user.password = "12345678"
asdict(user) # {"id": 5, "password": "12345678"}user.id = 20 # raise OverMaxErroruser.password = 10 # raise InvalidTypeErrortry:
user = User(id=20, password=10)
except ErrorContainer as errors:
errors["id"] # OverMaxError
errors["password"] # InvalidTypeErrorNote
The above type, size and length validation functions and error classes are not included in sigma.core packages.
They are included in sigma.standard packages.
user = User(id=20, password=10) # raise ErrorContainer
# equivalent to
# user = User(False, id=20, password=10)user = User(True, id=20, password=10) # raise OverMaxError or InvalidTypeErrorvalidate(User, *args, **kwargs)is equivalent to
User(*args, **kwargs)If you merely want to validate values and don't need the return value(Model instance),
use validate function to make the meaning clear.
