jsonschema - choosing between different objects in JSON-schema -


i'm creating schema receipts , want have master schema core concepts variety of different detail objects specialized receipt types (e.g. itemized hotel receipts, etc.) current implementation leveraging oneof mechanism in json-schema

{     "$schema": "http://json-schema.org/draft-04/schema#",     "title": "receipt",     "type": "object",     "properties": {         ...         "amount": { "type": "number" },         "detail": {             "type": "object",             "oneof": [                 { "$ref": "general-detail.schema.json" },                 { "$ref": "hotel-detail.schema.json" },                 ...             ]         }     } }

the problem approach when validate (using tv4), appears of schemas specified in oneof being checked, , in fact, returning errors. can minimize effect getting rid of detail property, moving oneof schema-level (e.g. outside of properties) , creating root property names in each of sub-schemas. however, in case, "missing required property: generaldetail" in event there's error when i'm validating hotel receipt type.

so 2 questions:

  • is possible use generic detail property i'm doing , not have validator validate each sub-schema in oneof structure (e.g. using oneof wrongly)?
  • if not possible, more fine having set of 'typed' detail properties (like 'generaldetail', 'hoteldetail', etc.) - there way specify group , 1 of them should exist in document being validated?

tia

all of schemas in oneof need validated in order validator ensure 1 of schemas pass. if none pass or more 1 pass, validator needs tell validation results of each schema in order determine how fix error.

so, because validator telling why each of schemas failing doesn't mean expects of schemas pass.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
