Como especificar qual item de um objeto JSON deve levar?
Usando Python ejsonschema
Estou tentando validar a atribuição deObjA
ouObjB
etc. parabeta
(test.json
)
{
"alpha": {
"beta": "ObjA"
}
}
No meu esquema (testschema.json
) beta
éoneOf
vários itens e cada item é definido como abaixo (com valores diferentes paraa
, b
ec
)
"ObjA": {
"type": "object",
"properties": {
"items": {
"a": [90, 95],
"b": [4, 8],
"c": [0.2, 0.6]
}
},
"additionalProperties": false
}
Isto é,beta
pode assumironeOf
valores que sãoObjA
, ObjB
, ObjC
eObjD
. Estou simplesmente tentando especificar qual deles deve usartest.json
"alpha": {
"type": "object",
"properties": {
"beta": {
"oneOf": [
{
"type": "object",
"properties": {
"ObjA": {
"type": "object",
"properties": {
"items": {
"a": [90, 95],
"b": [4, 8],
"c": [0.2, 0.6]
}
},
"additionalProperties": false
}
},
"additionalProperties": false
},
{
"type": "object",
"properties": {
"ObjB": {
"type": "object",
"properties": {
"items": {
"a": [100],
"b": [0],
"c": [0]
}
},
"additionalProperties": false
}
}
},
...
ObjC and ObjD defined
...
}
}
}
},
No entanto, ao tentar validar com relação ao esquema usandojsonschema.validate()
### Test the whole JSON is valid against the Schema
def test_valid__JSON_against_schema(self):
with open(schema_filename) as schema_file:
test_schema = json.load('testschema.json')
schema_file.close()
with open(json_filename) as json_file:
test_json = json.load('test.json')
json_file.close()
validate(test_json, test_schema)
Estou tendo o erro a seguir
Failed validating 'oneOf' in schema['properties']['alpha']['properties']['beta']:
Aqui está toda a mensagem

Alguém sabe a maneira correta de fazer isso?
Obrigado.
