[ json schema issue on required property ]
I need to write the JSON Schema based on the specification defined by http://json-schema.org/. But I'm struggling for the required/mandatory property validation. Below is the JSON schema that I have written where all the 3 properties are mandatory but In my case either one should be mandatory. How to do this?.
{
"id": "http://example.com/searchShops-schema#",
"$schema": "http://json-schema.org/draft-04/schema#",
"title": "searchShops Service",
"description": "",
"type": "object",
"properties": {
"city":{
"type": "string"
},
"address":{
"type": "string"
},
"zipCode":{
"type": "integer"
}
},
"required": ["city", "address", "zipCode"]
}
Answer 1
If your goal is to tell that "I want at least one member to exist" then use minProperties
:
{
"type": "object",
"etc": "etc",
"minProperties": 1
}
Note also that you can use "dependencies"
to great effect if you also want additional constraints to exist when this or that member is present.
Answer 2
{
...
"anyOf": [
{ "required": ["city"] },
{ "required": ["address"] },
{ "required": ["zipcode"] },
]
}
Or use "oneOf" if exactly one property should be present
