The form model

Form data is stored in the form model. The form model stores information about UI elements with an ID assigned and input parameters.

Note

If a UI element and an input parameter have the same ID, they are treated as the same piece of data.

The form model is considered a JSON schema object. Every element in the form model is transformed to a JSON schema property inside the object. The property name is the UI element or input parameter ID, and the type is given by the lists, below. Input parameters are string type by default, but if you give an input parameter and a UI element the same ID, the input parameter takes the data type of the UI element.

UI element types

Active elements

Active elements are available for both request and response mapping.

  • Button Group (when type is checkbox): Array of <String>

  • Button Group (when type is radio): String

  • Checkbox: Boolean

  • Date Picker: String

  • Group (when mode is repeater): Array of <Object<{ [component’s model property]: component type following this list }>>

  • Input (when element Type property is Text or Textarea): String

  • Input (when element Type property is Number): Number

  • Number Picker: Number

  • Password: String

  • Select (when multiple is false): Any of <String, Number>

  • Select (when multiple is true): Array of <Any of <String, Number>>

  • Switch: Boolean

  • Time Picker: String

Passive elements

Passive elements are only available for response mapping.

Example

Consider this UI builder form

../../../../_images/ss-uibuilder-mapping-example1.png

When deployed, a user enters some data.

../../../../_images/ss-uibuilder-mapping-example2.png

For this data, the form model can be represented as:

{
        "username": "johnsmith"
        "email": "john.smith@demoisv.com"
        "isActive": true
}

Note

Button has no ID, so there’s no value stored for it in the model. Only properties that are present in the model can be mapped.

The JSON schema that represents the form indicates that the form model is an object that contains three properties: username (which is a string), email (which is a string), and isActive (which is a boolean). We can also specify that there cannot be any other properties in our form model that are not listed in properties.

{
        "type": "object",
        "properties": {
                "username": {
                        "type": "string"
                },
                "email": {
                        "type": "string"
                },
                "isActive": {
                        "type": "boolean"
                }
        },
        "additionalProperties": false
}
