Not able to induce anyOf behavior with add_schema()

[jeyendranbalakrishnan]

I want to generate a schema with two sets of objects. combined with anyOf

import json 
from genson import SchemaBuilder

d11 = dict(a=1,b=2)
d12 = dict(a=3,b=4)
d21 = dict(c=2.0)
d22 = dict(c=3.0)

b1=SchemaBuilder()
b1.add_object(d11)
b1.add_object(d12)
s1 = b1.to_schema()

b2=SchemaBuilder()
b2.add_object(d21)
b2.add_object(d22)
s2 = b2.to_schema()

b=SchemaBuilder()
b.add_schema(s1)
b.add_schema(s2)

print(json.dumps(b.to_schema()))

gives

{
  "$schema": "http://json-schema.org/schema#",
  "type": "object",
  "properties": {
    "a": {
      "type": "integer"
    },
    "b": {
      "type": "integer"
    },
    "c": {
      "type": "number"
    }
  }
}

whereas I want it to generate:

  "$schema": "http://json-schema.org/schema#",
  "anyOf": [
    {
      "type": "array",
      "properties": {
        "a": {
          "type": "integer"
        },
        "b": {
          "type": "integer"
        },
       "required": ["a", "b"]
      }
    },
    {
        "type": "object",
        "properties": {
          "c": {
            "type": "number"
          },
         "required": ["c"]
        }
    }
  ]
}

How can I achieve this?

Your problem is that you aren't inputting any lists. If you do that, you will get anyOf.

from genson import SchemaBuilder

d1 = dict(a=1,b=2)
d2 = dict(c=2.0)
l1 = [1, 2]
l2 = [3.4, 5.6]

b=SchemaBuilder()

b.add_object(d1)
b.add_object(d2)
b.add_object(l1)
b.add_object(l2)
s = b2.to_schema()

print(b.to_json(indent=2))

this yields:

{
  "$schema": "http://json-schema.org/schema#",
  "anyOf": [
    {
      "type": "object",
      "properties": {
        "a": {
          "type": "integer"
        },
        "b": {
          "type": "integer"
        },
        "c": {
          "type": "number"
        }
      }
    },
    {
      "type": "array",
      "items": {
        "type": "number"
      }
    }
  ]
}
