AppML Models

Example

{
"security": "admin",
"rowsperpage" : 10,

"database": {
    "connection": "mysql",
    "sql"       : "SELECT * FROM Customers",
    "orderby"   : "CustomerName"}},

"filteritems" : [
    {"item" : "CustomerName", "label" : "Customer"},
    {"item" : "City"},
    {"item" : "Country"}],

"sortitems" : [
    {"item" : "CustomerName", "label" : "Customer"},
    {"item" : "City"},
    {"item" : "Country"}]
}

AppML Model Properties

Element Description
"data" Defines a flat file source for the model
"database" Defines a database source for the model
"filteritems" Defines filter restrictions
"rowsperpage" Defines number of rows to be fetched per page
"security" Defines the security for the model
"sortitems" Defines sorting restrictions

Application Security

You have to be logged in as a member of the "admin" group, to access this application:

Example

{
"security": "admin",
"database": {
    "connection": "mysql",
    "sql"       : "SELECT * FROM Customers",
    "orderby"   : "CustomerName"}
}

Private Models

You can add your own private data to the model.

This example suggests restrictions to data:

Example:

"restrictions" : {
    "fname" : {"maxlength": 40},
    "price" : {"max": 999,"min": 100}
    }

Model data can be used by server applications, and by your AppML controller.

This example uses model data to validate input:

Example:

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;
        }
}
