Dependencies

Would dependencies be complicated to implement?

https://spacetelescope.github.io/understanding-json-schema/reference/object.html#property-dependencies

I believe all scenarios of required fields would be covered.

If it’s too much work I’ll work around it.

That will do it for now.

I may look into automating the schema resolver. I’m sure it can all be done right from the original JSON Schema using the dependencies keyword.

Thanks again.

I would like to be able to conditionally display questions declaratively and I believe this could be supported through dependencies as well. Does the following example make sense?

{
  "title": "Person",
  "type": "object",
  "properties": {
    "Do you have any pets?": {
      "type": "string",
      "enum": [
        "",
        "No",
        "Yes: One",
        "Yes: More than one"
      ]
    },
    "How old is your pet?": {
      "type": "number"
    },
    "How old is your oldest pet?": {
      "type": "number"
    }
  },
  "required": [
    "Do you have any pets?"
  ],
  "dependencies": {
    "Do you have any pets?": {
      "oneOf": [
        {
          "properties": {
            "Do you have any pets?": {
              "enum": [
                "",
                "No"
              ]
            },
            "How old is your pet?": {
              "not": {}
            },
            "How old is your oldest pet?": {
              "not": {}
            }
          }
        },
        {
          "properties": {
            "Do you have any pets?": {
              "enum": [
                "Yes: One"
              ]
            },
            "How old is your oldest pet?": {
              "not": {}
            }
          },
          "required": [
            "How old is your pet?"
          ]
        },
        {
          "properties": {
            "Do you have any pets?": {
              "enum": [
                "Yes: More than one"
              ]
            },
            "How old is your pet?": {
              "not": {}
            }
          },
          "required": [
            "How old is your oldest pet?"
          ]
        }
      ]
    }
  }
}

If “Do you have any pets?” is “” or “No” then no further questions are present nor required; if it is “Yes: One” then “How old is your pet?” is present and required but “How old is your oldest pet?” is not; if it is “Yes: More than one” then “How old is your oldest pet?” is present and required but “How old is your pet?” is not.

This would support dynamic schemas without the need for a schema resolver which would simplify things, especially when array objects need to be dynamic, etc.
