Get all fields from Documents and their type to validate insert new values

[AmitMalka94]

I want to insert every time value to field in Document Object i crated. To know if the value is valid i want to use Fields and their type with _deserialize method.

Example: validate Number with correct type without knowing Number is a Float type

class EsDoc(Document):
----Number = Float()

doc = EsDoc
setattr(doc, 'Number', 't') # don't raise error

if i want to validate i must know that number is Float to use _deserialize method:

Float._deserialize(doc, doc.Number) # raise the error i want

mybe i miss something, there is a way to validate field type without knowing his type? or get his type in some way and then validate by this type?

Thanks
