How to add dependency

[vicky-blr]

I would like to know how to add dependency on another property's value. For e.g. if I want B to be dependent on A, I can add below.

"dependencies": {
        "B": ["A"]
      }

This works perfectly for me.

Now, say A is a boolean and if I want to add a check that B should only be defined if A is true?

Hi @vicky-blr,

This sounds more like a general question regarding JSON Schema than how to produce that with the generator library. 😃
For that, I suggest you have a look at: https://tour.json-schema.org/content/05-Conditional-Validation/04-if-then-keyword
By swapping the if and then subschema in their lesson's example you'd get pretty close to what you're describing as your use case:

{
  "type": "object",
  "properties": {
    "A": {"type": "boolean"}
  },
  "if": { "required": ["B"] },
  "then": { "properties": { "A": { "const": true } }, "required": ["A"] },
}

I favor this alternative though: https://tour.json-schema.org/content/05-Conditional-Validation/03-Conditionally-Apply-a-Subschema

{
  "type": "object",
  "properties": {
    "A": {"type": "boolean"}
  },
  "dependentSchemas": {
    "B": { "properties": { "A": { "const": true } }, "required": ["A"] }    
  }
}

Both have the same meaning: if a property "B" is present, then a property "A" must be present and have the value true.
Note: It's important to include the "required": ["A"] in there, not just the true value.
You can play around with it on the json-schema.org lesson pages.

If you have any further questions on configuring your JSON Schema Generator to produce the desired output, I'm happy to help there as well. 😉
