enum list as object property in json schema - json

I'm looking to find a way to declare objects defined in an enum list.
Here is what I want to check :
{
"object1": {
"subobject1": {
"value": 123
},
"subobject2": {
"value": 456
}
},
"object2": {
"subobject3": {
"value": 789
}
},
"object3": {
"subobject4": {
"value": 123
}
},
"object4": {
"subobject5": {
"value": 234
}
}
}
Here is my schema that I want to use for validation :
{
"$schema": "http://json-schema.org/draft-04/schema#",
"type": "object",
"definitions": {
"list1": {
"enum": [
"object1",
"object2",
"object3",
"object4"
],
"list2": {
"enum": [
"subobject1",
"subobject2",
"subobject3",
"subobject4",
"subobject5"
]
}
}
},
"properties": {
"type": {
"anyOf": [
{
"$ref": "#/definitions/list1"
}
]
}
},
"additionalProperties": false
}
But I get the following error :
Property 'object1' has not been defined and the schema does not allow additional properties.
I really want to be very restrictive and be able to declare only the one that as listed in the enum because I know that if I remove "additionalProperties": false I can add any propertry I want and it works.

The instance you gave as example can be validated with the following schema
{
"type": "object",
"definitions": {
"list1": {
"properties": {
"subobject1": {"type": "object"},
"subobject2": {"type": "object"},
"subobject3": {"type": "object"},
"subobject4": {"type": "object"},
"subobject5": {"type": "object"}
}
}
},
"properties": {
"object1": {"type": "object", "$ref": "#/definitions/list1"},
"object2": {"type": "object", "$ref": "#/definitions/list1"},
"object3": {"type": "object", "$ref": "#/definitions/list1"},
"object4": {"type": "object", "$ref": "#/definitions/list1"}
},
"additionalProperties": false
}
Maybe it's not what you wanted? Am I close?

Json schema permits override of fields in objects in array

I have an json that looks like this
"List": {
{"Color": "red"},
{}
},
"Color": "grey"
}
whereas it means that the default color is grey, and the object in the list could override this Color.
The schema should allow the json to pass as long as default color(the property in the same level of List) is present. If not, it shall only allow the json to pass the schema check if all items in the list have specified a "Color".
May I know how can I write a json schema that does this check? I am aware of anyOf but I don't think it can check for all items in the array.
I tried
{
"type": "object",
"properties": {
"List": {"type": "array", "items": {"$ref:" "#/definitions/Item"}},
"Color": {"type": "string"}
},
"definitions": {
"Item": {"type: "object", "properties": " {"Color": {"type": "string"}}}
},
"anyOf": {
{
"type": "object",
"required": ["Color"]
},
{
"type": "object",
"List": {
"type": "array",
"items": {"$ref": "#/definitions/Item", "required": ["Color"]}
}
}
}
But it does not seem that the required color for the anyOf[1] is picked up by the validator.
Please help.! Thank you.
The schema in the other answer is correct, but is unnecessarily complicated. Here's an example that removes duplication and make the schema easier to read.
{
"$schema": "http://json-schema.org/draft-07/schema#",
"type": "object",
"properties": {
"List": {
"type": "array",
"items": {
"type": "object",
"properties": {
"Color": { "type": "string" },
"Shape": { "type": "string" }
}
}
},
"Color": { "type": "string" },
"Shape": { "type": "string" }
},
"required": ["List"],
"allOf": [
{ "$ref": "#/definitions/color-required-if-no-default-color" },
{ "$ref": "#/definitions/shape-required-if-no-default-shape" }
],
"definitions": {
"color-required-if-no-default-color": {
"anyOf": [
{ "required": ["Color"] },
{
"properties": {
"List": {
"items": { "required": ["Color"] }
}
}
}
]
},
"shape-required-if-no-default-shape": {
"anyOf": [
{ "required": ["Shape"] },
{
"properties": {
"List": {
"items": { "required": ["Shape"] }
}
}
}
]
}
}
}
I think I found out a way:
Schema is like below
{
"$schema": "http://json-schema.org/draft-07/schema#",
"type": "object",
"properties": {"Color": {"type":"string"}, "Shape": {"type": "string"}},
"allOf":[
{
"anyOf": [
{
"required": ["Color"],
"properties": {"List": {"type": "array", "items": {"$ref": "#/definitions/Item"}}}
},
{
"properties": {"List": {"type": "array", "items": {"$ref": "#/definitions/ColorItem"}}}
}
]
},
{
"anyOf": [
{
"required": ["Shape"],
"properties": {"List": {"type": "array", "items": {"$ref": "#/definitions/Item"}}}
},
{
"properties": {"List": {"type": "array", "items": {"$ref": "#/definitions/ShapeItem"}}}
}
]
}
],
"required": ["List"],
"definitions": {
"Item": {
"type": "object",
"properties": {}
},
"ColorItem": {
"allOf": [{"$ref": "#/definitions/Item"},
{"properties": {"Color": {"type": "string"}}, "required": ["Color"]}]
},
"ShapeItem": {
"allOf": [{"$ref": "#/definitions/Item"},
{"properties": {"Shape": {"type": "string"}}, "required": ["Shape"]}]
}
}
}
Basically this does what I want. So it will pass the json only if either there is a Color/Shape read from top-level json, or we can find it in the array.

Validate JSON Schema based on "type" property

I have the following JSON which validates against my current schema:
{
"information": [
{
"value": "closed",
"type": "power"
},
{
"value": "on",
"type": "door"
}
]
}
However, I want this validation to fail (since open/closed should relate to door, and on/off should only relate to power.
How can I tie the two together?
My current working schema:
"$schema": "http://json-schema.org/draft-07/schema#",
"type": "object",
"definitions": {
"Type": {
"type": "string",
"enum": ["power", "door"]
},
"Power": {
"type": "string",
"enum": ["on", "off"]
},
"Door": {
"type": "string",
"enum": ["open", "closed"]
},
"InformationField": {
"type": "object",
"required": [ "type", "value" ],
"properties": {
"label": { "type": "string" },
"value": {
"anyOf": [
{ "$ref": "#/definitions/Power"},
{ "$ref": "#/definitions/Door"}
]
},
"type": { "$ref": "#/definitions/Type" }
}
},
"Information": {
"type": "array",
"items": { "$ref": "#/definitions/InformationField" }
},
},
"properties": {
"information": { "$ref": "#/definitions/Information" }
},
}
I have a lot of types, so I want to do this in the cleanest way possible.
Here is one of my attempts, which fails to validate correctly:
{
"$schema": "http://json-schema.org/draft-07/schema#",
"type": "object",
"definitions": {
"Type": {
"type": "string",
"enum": ["power", "door"]
},
"Power": {
"type": "string",
"enum": ["on", "off"]
},
"Door": {
"type": "string",
"enum": ["open", "closed"]
},
"InformationField": {
"type": "object",
"required": [ "label", "value" ],
"properties": {
"label": { "type": "string" },
"type": { "$ref": "#/definitions/Type" }
},
"anyOf": [
{
"if": {
"properties": { "type": { "const": "power" } }
},
"then": {
"properties": { "value": { "$ref": "#/definitions/Power" } }
}
},
{
"if": {
"properties": { "type": { "const": "door" } }
},
"then": {
"properties": { "value": { "$ref": "#/definitions/Door" } }
}
}
]
},
"Information": {
"type": "array",
"items": { "$ref": "#/definitions/InformationField" }
},
},
"properties": {
"information": { "$ref": "#/definitions/Information" }
},
}
(Validates, even though it shouldn't ...)
Changed anyOf to allOf in my attempt, which fixes validation.
My reasoning as to why this works:
From the anyOf JSON schema spec:
5.5.4.2. Conditions for successful validation
An instance validates successfully against this keyword if it validates successfully against at least one schema defined by this keyword's value.
If my first if condition is false, then it doesn't evaluate the then, and is therefore valid.
Using allOf evaluates every condition's validation (not the condition itself).

why doesn't json schema validate definitions defined in required attribute

I'm trying to create a json schema that validates an object depending on its type. It picks the right definition, however, it doesn't validate the required attributes in the selected definition. Here is the json schema i am trying:
{
"$schema": "http://json-schema.org/draft-07/schema#",
"definitions": {
"literal": {
"type": "object",
"properties": {
"raw": { "type": "string" }
},
"required": ["raw"],
"additionalProperties": false
},
"identifier": {
"type": "object",
"properties": {
"name": { "type": "string" }
},
"required": ["name"],
"additionalProperties": false
}
},
"type": "object",
"oneOf": [
{
"type": "object",
"properties": {
"type": {
"enum": ["Literal"]
},
"content": { "$ref": "#/definitions/literal" }
}
},
{
"type": "object",
"properties": {
"type": {
"enum": ["Identifier"]
},
"content": { "$ref": "#/definitions/identifier" }
}
}
],
"required": ["type"]
};
the following schema is valid, even tho its missing the "raw" property:
{ "type" : "Literal" }
thanks
There is no keyword content in JSON Schema spec.
Once you have asserted "type":"object" in root schema, there is no need to do it again in subschema.
In order to combine object type enumerated value with associated extended definition, you need allOf keyword.
Also in definitions if you use "additionalProperties": false you have to list all properties of the object (see "type": {}). For previously defined/validated properties you can just use permissive schema: {} or true.
{
"$schema": "http://json-schema.org/draft-07/schema#",
"definitions": {
"literal": {
"properties": {
"type": {},
"raw": { "type": "string" }
},
"required": ["raw"],
"additionalProperties": false
},
"identifier": {
"properties": {
"type": {},
"name": { "type": "string" }
},
"required": ["name"],
"additionalProperties": false
}
},
"type": "object",
"oneOf": [
{
"allOf": [
{
"properties": {
"type": {
"enum": ["Literal"]
}
}
},
{"$ref": "#/definitions/literal"}
]
},
{
"allOf": [
{
"properties": {
"type": {
"enum": ["Identifier"]
}
}
},
{"$ref": "#/definitions/identifier" }
]
}
],
"required": ["type"]
}

Json schema auto completion property

I have already created my own schema on intellij environment, and it's working good, but still have problems in auto completion which provides intellij to the schema,
for example if object "car" defined in json schema then intellij can recognize that there's such object in the schema and intellij will give it as suggestion through out coding json, the problem that I'm facing is that the suggestions are contains all the objects that defined in the schema, but the expectations are to get the objects which defined under the scoop of another object
This is some code of my own schema:
{
"$schema": "http://json-schema.org/draft-04/schema#",
"title": "Pipe File",
"type": "object",
"definitions": {
"Pipe": {
"type": "object",
"properties": {
"components": {
"$ref": "#/definitions/components"
}
},
"required": [
"components"
]
},
"components": {
"description": "section which defines the pipes in the file",
"type": "array",
"minItems": 1,
"items": {
"oneOf": [
{
"$ref": "#/definitions/setValuesComponent"
},
{
"$ref": "#/definitions/invokeWebServicesComp"
}
]
}
},
"setValuesComponent": {
"type": "object",
"properties": {
"name": {
"type": "string"
},
"type": {
"enum": [
"setValuesComp"
]
},
"out": {
"type": "object",
"properties": {
"dateFormat": {
"$ref": "#/definitions/setValuesCompOut"

"setValuesCompOut": {
"type": "object",
"properties": {
"exprValue": {
"type": "string"
},
"ctxEntry": {
"type": "string"
},
"value": {
"type": "string"
},
"exprConst": {
"type": "string",
"pattern": "(Class|class)\\.\\w+\\.\\w+"
}
},
"anyOf": [
{
"required": [
"exprValue"
]
},
{
"required": [
"ctxEntry"
]
},
{
"required": [
"value"
]
},
{
"required": [
"exprConst"
]
}
]
},
"invokeWebServicesComp": {
"type": "object",
"properties": {
"name": {
"type": "string"
},
"type": {
"enum": [
"invokeWebServices"
]
},
"mode": {
"enum": [
"innerJoin",
"leftJoin",
"union",
"parallelJoin"
]
},
"method": {
"type": "string"
},
"headers": {
"$ref": "#/definitions/invokeWebServicesCompHeaders"
},
"dataFilePath": {
"type": "string"
},
"restRelativeUrl": {
"type": "string"
},
"in": {
"$ref": "#/definitions/invokeWebServicesCompIn"
},
"out": {
"$ref": "#/definitions/invokeWebServicesCompOut"
}
},
"required": [
"type",
"name",
"out",
"in"
]
},
"invokeWebServicesCompOut": {
"type": "object",
"patternProperties": {
"doc": {
"type": "string",
"pattern": ".+"
}
}
},
"invokeWebServicesCompHeaders": {
"type": "object",
"patternProperties": {
".{1,}": {
"type": "string",
"pattern": ".+"
}
}
},
"invokeWebServicesCompIn": {
"type": "object",
"patternProperties": {
".{1,}": {
"type": "string",
"pattern": ".+"
}
}
},
"properties": {
"pipes": {
"description": "section which defines the mandatory pipes object in the file",
"type": "object",
"patternProperties": {
".{1,}": {
"$ref": "#/definitions/Pipe"
}
}
}
},
"required": [
"pipes"
]
}
}
So what I expected is, when the type of object determined to "setValuesComp", the auto completion will suggest the relevant properties, that's mean it will not suggest "in" property which is belong to "invokeWebServicesComp" not "setValuesComponent".this picture show the auto complete problem in my real environment
Your JSON schema seems to be invalid. The below JSON content should be present inside object type.
"properties": {
"pipes": {
"description": "section which defines the mandatory pipes object in the file",
"type": "object",
"patternProperties": {
".{1,}": {
"$ref": "#/definitions/Pipe"
}
}
}
},
"required": [
"pipes"
]
In your schema, it is present as part of the "definitions". Please make this correction and then check if you are able to get the suggestions.

AJV schema validation error

I have the input json like below,
{"contents":[{"type":"field"},{"type":"field","itemId":"594b9980e52b5b0768afc4e8"}]}
the condition is,
if the type is 'field', then 'itemId' should be the required field
and if the type is 'fieldGroup' or 'subSection', then 'itemId' is optional
This is the Json Schema I tried and its not working as expected,
"type": "object",
"additionalProperties": false,
"properties" : {
"contents" : {
"type" : "array",
"items": {"$ref": "#displayItem" }
}
},
"definitions": {
"displayItem" : {
"id": "#displayItem",
"type": "object",
"items": {
"anyOf": [
{"$ref": "#fieldType"},
{"$ref": "#fieldGroupSubSectionType"}
]
}
},
"fieldType" : {
"id": "#fieldType",
"type": "object",
"additionalProperties": false,
"properties": {
"itemId": {
"type": "string"
},
"type": {
"type": "string",
"enum": ["field"]
}
}
},
"fieldGroupSubSectionType" : {
"id": "#fieldGroupSubSectionType",
"type": "object",
"additionalProperties": false,
"properties": {
"itemId": {
"type": [ "string", "null" ]
},
"type": {
"type": "string",
"enum": [
"fieldGroup",
"subSection"
]
}
}
}
}
Any help / workaround with Sample Json Schema to achieve the above use case is appreciated.
If I understand the description of what you want correctly, then the json example you provide is not valid since it has a type: "field" but does not have an "itemId" property.
Assuming that is true. Instead of using
type: ["string", null]
use the required property.
I changed your schema a bit, instead of having separate definitions I inlined them, but other than that (and the use of required) is the same:
{
"type": "object",
"additionalProperties": false,
"properties": {
"contents": {
"type": "array",
"items": {
"anyOf": [
{
"type": "object",
"additionalProperties": false,
"properties": {
"itemId": {
"type": "string"
},
"type": {
"type": "string",
"enum": [
"field"
]
}
},
"required": [
"itemId"
]
},
{
"type": "object",
"additionalProperties": false,
"properties": {
"itemId": {
"type": "string"
},
"type": {
"type": "string",
"enum": [
"fieldGroup",
"subSection"
]
}
}
}
]
}
}
}
}
Here is your answer with a little cleanup for best practices and style. The trick is that you need to use implication "a implies b <=> (not a) or b". In this case you have "type = field implies itemId is required <=> type is not field or itemId is required".
{
"type": "object",
"properties": {
"contents": {
"type": "array",
"items": { "$ref": "#/definitions/displayItem" }
}
},
"definitions": {
"displayItem": {
"type": "object",
"properties": {
"itemId": { "type": "string" },
"type": { "enum": ["field", "fieldGroup", "subSection"] }
},
"anyOf": [
{ "not": { "$ref": "#/definitions/fieldType" } },
{ "required": ["itemId"] }
]
},
"fieldType": {
"properties": {
"type": { "enum": ["field"] }
}
}
}
}
