Deserialization errors not accessible from exception

[miracle2k]

I'd like to parse incoming request data using schema.load() and have my framework handle any parsing errors.

It seems that returning a clear error message to the user is hard to do, because I cannot figure out how to know from an UnmarshallingError which field actually failed.

Can you please provide a code snippet to show where you are receiving the error? Schema#load should return a dictionary of validation errors (keyed by field name) as the second element of its return value.

Yes, but I have set strict=True to raise an exception, and I want to let the exception bubble up to my Rest framework, so I can handle request parsing exceptions in one single place. I don't have access to the return value at that point, but I think it makes sense to attach it to the exception.

Oh, I see now. I didn't realize you were using strict=True.

OK, I don't see a problem with storing the field name and field object on the UnmarshallingError. I will implement this shortly.
