How to render a tuple?

General

Hi all!

I’m using JSONForms v3.0.0-alpha.3 and I’m having problems rendering a form that contains the data below:

{
	"offers_to_testdrive": [
		[
			"Sumá 30GB GRATIS a tu plan. 10GB por mes durante 3 meses",
			"Usá tu Movistar sin preocuparte por 90 días y conocé tu plan ideal.",
			"Mirá también tus series favoritas con Movistar TV."
		],
		[
			{
				"benefits": "10GB al mes",
				"msg": "Para navegar",
				"type": "data"
			},
			{
				"benefits": "Llamadas",
				"msg": "A todas las compañías",
				"type": "call"
			}
		],
		[
			"No incluye llamadas internacionales ni Roaming. Tope de minutos a otras compañías: 1.000",
			"El uso de Test Drive no genera cargos adicionales en tu factura."
		]
	]
}

Currently I’m using this schema:

{
	"type": "object",
	"required": [
		"offers_to_testdrive"
	],
	"properties": {
		"offers_to_testdrive": {
			"type": "array",
			"items": [
				{
					"type": "array",
					"items": {
						"type": "string"
					}
				},
				{
					"type": "array",
					"items": {
						"type": "object",
						"properties": {
							"benefits": {
								"type": "string"
							},
							"msg": {
								"type": "string"
							},
							"type": {
								"type": "string"
							}
						},
						"required": [
							"benefits",
							"msg",
							"type"
						]
					}
				},
				{
					"type": "array",
					"items": {
						"type": "string"
					}
				}
			]
		}
	}
}

And I’m getting the following errors when opening the form elements:

Any ideas on what can I do with the schema? I can’t change anything from the data btw.

Thanks in advance :blush:

Hello @MauricioZanon,

JSON Forms does not contain a default renderer to show arrays with arrays as their items. Consequently, JSON Forms tells you that it could not find any applicable renderer.

To solve this, you can implement a custom renderer that can handle these kind of arrays.
See here for documentation on creating custom renderers: Custom Renderers - JSON Forms
