I have change formName/Modal Class Name in below search URL like SubjectMaster to SM.
When I search/filter data using GET method at time change my required name.
http://demo.local/report/subject?SubjectMaster[year]=3&SubjectMaster[course]=&SubjectMaster[session]=&SubjectMaster[status]=
If I understand correctly you need to override the formName method on the model.
class SubjectMaster extends ...
{
public function formName()
{
return 'SM';
}
}

I want to acces a function from another class. A solution would be to initalize the second class in the class I want to access. Like this:
class Calendarsub extends State<Calendar> with SingleTickerProviderStateMixin{
final TableCalendar tableCalendar;
Calendarsub(this.tableCalendar);
When I do this I can acces the functions but the app is not running because the Stateful Widget says: "1 required Argument expected but 0 found."
class Calendar extends StatefulWidget {
#override
State<StatefulWidget> createState() {
return Calendarsub(); // In this bracket must be the argument
// But I don't know which one
}
}
You constructor needs 1 argument - TableCalendar
So, you have to initialize it with this value:
TableCalendar tableCalendar = TableCalendar(); //or somethimg like that
Calendarsub calendar = Calendarsub(tableCalendar);
or make this parameter optional:
class Calendarsub extends State<Calendar> with SingleTickerProviderStateMixin{
TableCalendar tableCalendar;
Calendarsub({this.tableCalendar});
in second case creating will be like:
Calendarsub calendar = Calendarsub(tableCalendar: TableCalendar());
It sounds like you have two classes using the same name
Calendar, a subclass of StatefulWidget, which takes a parameter
Calendar, a State, which doesn't take any parameter
This confuses the compiler. You need to rename so that there's no name conflict anymore.
Introduction
In MVC Core I have a base ViewModel and two ViewModels included in the base model as properties, like so:
public class BaseViewModel
{
public FirstViewModel First { get; set; }
public SecondViewModel Second { get; set; }
}
In FirstViewModel I added a custom validation attribute on one of the properties, inheriting from RemoteAttribute. My goal is to use this attribute comparing the value to a property in SecondViewModel. I've set this up using the AdditionalFields property of the RemoteAttribute.
I think my problem lies in the way the HTML attributes are added to the control in the razor view:
data-val-remote-additionalfields="*.PropOfModelFirst,*.PropOfModelSecond"
When the clientside validation is calling the controller action, the *. is replaced by the framework by First., which is wrong, because the second value is not part of the First-class.
I tried prepending the classname to the second property, resulting in
data-val-remote-additionalfields="*.PropOfModelFirst,*.Second.PropOfModelSecond"
but as can be expected this is changed to First.Second.PropOfModelSecond.
Question
Can the AdditionalFields property be used to compare against values from another ViewModel?
You cannot use AdditionalFields to compare against values from another ViewModel. The reason is that the rules are added to jquery.validate.js by the jquery.validate.unobtrusive.js plugin (which reads the data-val-* attributes generated by the HtmlHelper methods). Specifically it is the adapters.add("remote", ["url", "type", "additionalfields"], function (options) { method that is pre-pending First to the property names.
One option would be to use a single 'flat' view model containing all properties.
If that is not desirable, then you can just write your own ajax code to call your server method that performs the validation. This actually has some added performance benefits as well. By default, after initial validation triggered by the .blur() event, validation is performed on every .keyup() event, meaning that you are potentially making a lot of ajax and database calls if the user initially entered an invalid value.
Remove the [Remote] attribute, and add the following script (I'll assume the properties are First.ABC and Second.XYZ)
$('#First_ABC').change(function() {
var url = '#Url.Action(...)'; // add your action name
var input = $(this);
var message = $('[data-valmsg-for="First.ABC"]'); // or give the element and id attribute
$.post(url, { abc: input.val(), xyz: $('#Second_XYZ').val() }, function(response) {
var isValid = response === true || response === "true";
if (isValid) {
input.addClass('valid').removeClass('input-validation-error');
message.empty().addClass('field-validation-valid').removeClass('field-validation-error');
} else {
input.addClass('input-validation-error').removeClass('valid');
message.text(response).addClass('field-validation-error').removeClass('field-validation-valid');
}
})
});
where the controller method would be
[HttpPost]
public ActionResult Validate(string abc, string xyz)
{
bool isValid = .... // code to validate
if (isValid)
{
return Json(true, JsonRequestBehaviour.AllowGet);
}
else
{
return Json("your error message", JsonRequestBehaviour.AllowGet)
}
}
I would like to say that i am quite new to prestashop.
I have added FrontController.php to override/classes/controller.
The file contains the following code
class FrontControllerCore extends Controller
{
public function thefunct()
{
return 'AA';
}
}
Now in the header.tpl i try to call the function by using {FrontController::thefunct()}.
When I put the public function in classes/controller it works, but when I put it in the override folder it doesn't.
How do I display the function in my header.tpl?
And how does the override folder work then?
(I assume you use ps 1.5)
If you are overriding FrontController you need to initiate your class like so
class FrontController extends FrontControllerCore
and delete cache/class_index.php file, (I mean, delete it everytime you override new controller or class)
Teach yourself how to override in ps. through excellent docs.
EDIT:
class FrontController extends FrontControllerCore {
//here you should create and assign variables which you want to use in templates
public function initContent()
{
parent::initContent();
//in such a way you assign variables into smarty template
$this->context->smarty->assign(
array(
'acme_variable' => $this->acme()
)
);
}
protected function acme()
{
return "Wile E. Coyote and The Road Runner";
}
}
//header.tpl
<div>{$acme_variable}</div>
I tried doing
trace(classname.functionname.variablename);
//or
trace(classname.functionname().variablename);
Didn't work.. any idea, to get from the classname.as the variable, that's inside a function?
Btw i tried making the function static, still didn't work
Any idea?
There's no way, as those variables that are defined inside a function only live as long as the function is executed, and disappear once there's a return or end of function body. In order to get whatever value you want from a function, make a class variable outside the function, assign it the value you want within that function, and address it from elsewhere.
class test {
public static var foo:Number;
function bar():void {
// ... some code
foo=baz*2.54;
// ... more code
}
}
class elsewhere {
...
trace(test.foo);
...
}
the variables created inside a function are only available in the scope of that function.
if the variables are class member variables (declared public on a class);
public class x {
public var varName:String="";
}
you will be able to access them as
classInstanceRef.varName
needless to say you will need to instantiate from that class an instance.
Unless your variable is declared static on the class
public static varName:String="";
and in that case you can access it using
className.varName;
I'm building a mobile AIR app using Flash Builder 4.5. The initial view in my views package is TestHomeView.mxml. I want to refer to it in one of my .as classes elsewhere in the app, and I'm not sure how to do that.
Theoretically I should be able to add an "id" attribute to TestHomeView.mxml, but FB gives me an error: "id is not allowed on the root tag of a component". The root tag is s:view.
The reason I need to do this is that within another class I make various calculations and then need to pass an array of values to a component in my view class. So in SomeOtherActionScriptClass.as I first assemble the array, myArray, and then in that class I want to do this:
myViewComponent.viewArray = myArray;
If I'm going to do that, I also need to import the view class into the .as class, which strikes me as weird. So is there a simple way to do what I want, or do I have to dispatch a custom event which contains the array, and listen for it in the view class?
EDIT - Based on the below MVC suggestion I did the following in model:
[Bindable]
public class Model
{
private static var myModel:Model;//doesn't let me name it 'model' because
//I have a package named 'model'
public var myArray:Array; //its value set later in model code
public function Model()
{
if ( Model.myModel != null ){
throw new Error( "Only one Model instance should be instantiated" );
}
}
// singleton: always returns the one existing static instance to itself
public static function getInstance() : Model {
if ( myModel == null ){
myModel = new Model();
}
return myModel;
}
Then in the view code I have:
[Bindable] //do I actually need this?
private var myModel:Model = Model.getInstance();
var viewArray = new Array();
viewArray = myModel.myArray;
But it is coming back null. It isn't null when I put a breakpoint in the Model class, but when I try to access it from the view class, it's null. The model itself isn't null, but that variable is.
What am I doing wrong?
Thanks.
First, if you are trying to make a singleton in AS3 you should first create a class, within the same class file as Model, that is used to ensure you can only create the class once.
Add this class at the bottom of the Model class file (outside of the Model class):
internal class SingletonEnforcer{}
Then create the Model constructor like this:
public function Model(enforcer:SingletonEnforcer){ Init(); } // if init code is needed
public static function get Instance():Model
{
if (!myModel){
myModel = new Model(new SingletonEnforcer());
}
return myModel;
}
Now you don't have to throw an exception for creating a second instance because it isn't possible.
I'm not sure about your first question of referencing your app's main mxml, but if you were asking how to call the app that is running (like WindowedApplication in AIR) then you would call it like this:
// my WindowedApplication file = MyApp.mxml
MyApp(this.parentApplication)
That will return the app's instance.
Once you've set up the Singleton like I have it above you should be able to access your array like:
Model.Instance.myArray;
I hope this helps!
Follow the MVC pattern.
Create Model class (make it Bindable) with a property viewArray. Bind to this property from your View. And in any other class just change viewArray property of the model. The binding event will be fired and this property will also be changed in your View. To make your Model "visible" from any point, you can make it a Singleton.
