Is it possible to know the path of error

[Freed-Wu]

Assume Invalid will trigger error when validate():

{"name" : "a", "attr": {"price" : "Invalid", "number": 20}}

Is it possible to know the path of error like .attr.price? TIA!

Yes, that is called the "path" of the error, and is available on any ValidationError object. See here for details.
