Schema validation error - django

Question

I have used a field 'timestamp' is of type 'datetime.datetime' used in models.py in one of the django project,
Here is data :
{"bedId": "5807a14", "description": "",
"timestamp": "2013-09-16T15:40:16.383133", "encounterId": null, "patientId": null, "type":
"end_of_shift_note", "triggeredBy": "abc"}
Here is schema :
schema =
{
"type":"object",
"$schema": "http://json-schema.org/draft-03/schema",
"id": "http://jsonschema.net",
"required":true,
"properties":{
"type": {
"type":"string",
"id": "http://jsonschema.net/bedNumber",
"required":true
},
"encounterId": {
"type":"string",
"id": "http://jsonschema.net/encounterId",
"required":true
},
"timestamp": {
"type" :["null","string","date-time"],
'required' :false
},
"bedId": {
"type":"string",
"id": "http://jsonschema.net/cleaningStatus",
"required":true
},
"patientId": {
"type":["string","null"],
"id": "http://jsonschema.net/facilityId",
"required":true
} ,
"id": {
"type":["string","null"],
"id": "http://jsonschema.net/id",
"required":false
},
"triggeredBy": {
"type":["string","null"],
"id": "http://jsonschema.net/lastCleanedTime",
"required":false
}
}
}
On doing schema validation : https://pypi.python.org/pypi/json-schema-validator
def assertDataMatchesSchema(self, data, schema_file_name):
with open(os.path.join("hma/resource_jsonschema", schema_file_name)) as schema_file:
try:
schema = json.load(schema_file)
validate(data, schema)
except Exception as e:
print "Schema validation Error Message :",e.message
It is giving error on terminal:
Schema validation Error Message : Expecting property name: line 19 column 5 (char 401)
Problem is simple: What would be the type format for timestamp used in above jsonschema?
Please help

Got your problem:-
You are giving type instead of format.
Following example is working for me:-
data = {"timestamp": "2013-09-16T15:40:16.21211"}
schema ="""{
"type":"object",
"$schema": "http://json-schema.org/draft-03/schema",
"id": "http://jsonschema.net",
"required":true,
"properties":{
"timestamp": {
"format" :"date-time",
"type":"string",
"required" :false
}
}}"""
jsonschema.validate(data,json.loads(schema))
