List of objects with required values

[Siecje]

How do you define required values in a list?

I have a list of objects with a property which is an enum with 10 options. But the list must contain at least 4 items with specific field values.

For example if the list is for contact information, the field property of each list object can be phone_number, or cell_number, or address, or first_name, last_name, parent1_name, etc.

The list must have a telephone number either phone_number or cell_number, but not both and then it must contain address, first_name and last_name and other fields are optional.

contact_information: [
  {
    field: "phone_number",
    value: "",
  },
]

"type": "array",
"items": { // this schema applies to all items
  "type": "object",
  "required": [ "address", "first_name", "last_name" ],
  "properties": {
    "address": { "type": "string", ... },
    .. all your other property definitions here...
  },
  "oneOf": [
    { "required": [ "phone_ number" ] },
    { "required": [ "cell_ number" ] }
  ]
}

See https://json-schema.org/understanding-json-schema/reference/combining.html and https://json-schema.org/understanding-json-schema/reference/array.html

I believe this works for making one of two fields required but how can you specify certain values of an list of enums are required?

The problem is they are not different fields.

It is a list of objects with field having different values.

contact_information: [
  {
    field: "phone_number",
    value: "",
  },
{
    field: "cell_number",
    value: "",
  },
{
    field: "address",
    value: "",
  },
{
    field: "first_name",
    value: "",
  },
]

"contact_information": {
            "type": "array",
            "items": {
                "type": "object",
                "properties": {
                    "field": {
                        "enum": [
                            "first_name",
                            "last_name",
                            "address",
                            "phone_number",
                            "cell_number",
                        ]
                    },

oh I see, they are not property names, but property values.

Then you would do this:

"type": "array",
"items": {
  "type": "object",
  "required": [ "field", "value" ],
  "properties": {
    "field": { "enum": [ "first_name", "last_name", ... ] },
    "value": { "type": "string" }
  },
},
"allOf": [
  { "contains": { "properties": { "field": { "const": "first_name" } } } },
  { "contains": { "properties": { "field": { "const": "last_name" } } } },
  { "contains": { "properties": { "field": { "const": "address_name" } } } }
],
"oneOf": [
    { "contains": { "properties": { "field": { "const": "phone_number" } } } },
    { "contains": { "properties": { "field": { "const": "cell_number" } } } }
]

You should be able to find the rest of what you need at the documentation site I listed above. Try experimenting and see what happens!
