cannot collect all model errors

[dedominicisfa]

`from schematics.models import Model
from schematics.types import StringType, FloatType

class schema(Model):
f1 = StringType(choices=['a'])
f2 = FloatType()

sample ={'f1': 'b', 'f2': 'x'}
instance = schema (sample)
instance.validate`

The exception only shows the float error without even initialixing the instance. How do I collect all errors according to documentation?

Looking at the library code, I set validate=True in the model construvtor and I collect both errors now. the issue remains that the instance is not created and, if I set f1='a', so it's valid, I'd expect that instance.f1 would be available as 'a'. But as the instance does not initialize, I haven't f1 available even if it is valid
