Segurança do aplicativo
Você precisa estar logado como membro do grupo "admin", para acessar este aplicativo:
Exemplo
{
"security": "admin",
"database": {
"connection": "mysql",
"sql" : "SELECT * FROM Customers",
"orderby" : "CustomerName"}
}
Modelos particulares
Você pode adicionar seus próprios dados privados ao modelo.
Este exemplo sugere restrições aos dados:
Exemplo
"restrictions" : {
"fname" : {"maxlength": 40},
"price" : {"max": 999,"min": 100}
}
Os dados do modelo podem ser usados por aplicativos de servidor e por seu controlador AppML.
Este exemplo usa dados de modelo para validar a entrada:
Exemplo
function myController($appml) {
if ($appml.message == "submit") {
var price = document.getElementById("price").value;
if (price < $appml.model.restrictions.price.min) {
$appml.displayError(15, "Price
too low!");
return;
}
}
