Unchecked checkbox show up as checked

I have the following schema for checkbox:

{
type: "checkbox",
label: "Terms and Conditions",
model: "terms",
default: false
}

When I save the form, it posts the string “false” to the server.

So when the data is read from the server and the response is assigned to the model (ex. when editing an existing form), the component interprets “false” as truthy (strings are truthy) and makes the checkbox ticked.

You can define a “get” method in schema, where you can convert the model value.

{
    type: "checkbox",
    label: "Checkbox",
    model: "status",
    inputName :"checkname",
    get(model) {
        if (model){
            if (isString(model.status))
                return model.status === "true" ? true : false;
            
            return model.status;
        }
    }
}
